The Three Gorges Dam is the world’s largest hydropower project and most notorious dam. The massive project sets records for number of people displaced (more than 1.2 million), number of cities and towns flooded (13 cities, 140 towns, 1,350 villages), and length of reservoir (more than 600 kilometers).
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, China.
The Three Gorges Dam is the world’s largest power station in terms of installed capacity (22,500 MW).
In 2014, the dam generated 98.8 terawatt-hours (TWh) and had the world record, but was surpassed by the Itaipú Dam in Panama, which set the new world record in 2016, producing 103.1 TWh.
Except for the locks, the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. The ship lift was complete in December 2015. Each main water turbine has a capacity of 700 MW.
While Three Gorges is the world’s biggest hydro project, the problems at Three Gorges are not unique. Around the world, large dams are causing social and environmental devastation while better alternatives are being ignored.

THE National Economic and Development Authority (Neda) Board’s Investment Coordination Committee-Cabinet Committee (ICC-Cabcom) has approved the Ambal-Simuay River and Rio Grande de Mindanao River Flood Control Projects during its meeting on March 8, 2018.
"The Mindanao flood control projects, costing P39.2 billion, would involve the construction of various flood management infrastructure such as dikes and floodgates along the Ambal-Simuay and Rio Grande de Mindanao which are parts of the Mindanao River Basin, the second largest river basin in the country," Neda said in a statement.
According to the data provided by the Mindanao Development Authority (Minda), the project is seen to mitigate flooding in Cotabato City and the municipalities of Sultan Kudarat and Sultan Mastura in Maguindanao.
For the Ambal-Simuay flood control, the project will involve river widening and construction of parallel dikes along the river to the cut-off channel; establishment of a new channel with a dike-to-dike width of 250 meters; dredging and excavation of an estimated 2.87 million cubic meters of materials to achieve the design river width covering a total length of 11.2 kilometers (km); and construction of an 11.6km and a 9.1km dike along the left and right banks.
For the Rio Grande de Mindanao, the project will involve channel dredging and construction of dikes, retaining walls, and flood gates; dredging works covering a total length of 6.1 km and an estimated volume of 7.87 million cubic meters of dredged materials; construction of the dikes and retaining walls with a total length of 25 km; and installation of flood gates at every entrance or exit of the creeks connected to Rio Grande de Mindanao, with 23 flap gates.
The implementation of the project will be within six years and will involve the procurement of consulting services; consulting services for the detailed engineering design and construction supervision; procurement of civil works contractor; and construction works.
Aside from its infrastructure component, the project also aims to strengthen the flood management capabilities of and coordination among concerned government agencies and local government units.
The project is among the three new projects that were approved by the Neda ICC-Cabcom. The other two are the 10 Proposed Priority Bridges Crossing Pasig-Marikina River and Manggahan Floodway of the Department of Public Works and Highways and the Rural Agro-Enterprise Partnership for Inclusive Development and Growth (Rapid Growth) Project of the Department of Trade and Industry (DTI).
Neda said the 10 priority bridges project aims to improve road transport network capacity and efficiency in Metro Manila by adding fix links and alternate routes, was also approved.
The DTI's Rapid Growth project, which has a total cost of P4.78 billion, seeks promote productive rural enterprises and value chain development; increase competitiveness and ease of doing business; invest in human capital and innovative technologies; and match skills development with private sector demand.
These ICC-approved projects will be elevated to the Neda Board, chaired by President Rodrigo Duterte, for confirmation. (RJL with PR)

Research paper: Cost modelling and design optimisation of tidal stream turbines
A newly developed cost model for tidal stream turbines is presented. The model is based on (a) an existing tidal stream turbine cost model, (b) published CapEx data from an operational tidal stream turbine array, and (c) wind turbine cost data. The new cost model is utilised to establish cost-effective tidal stream turbine design, with the aim of reducing cost of energy through appropriate sizing of turbine rated power and rotor diameter for a given resource. A validated hydrodynamic model is used to estimate turbine energy yield at locations in Ramsey Sound, allowing cost of energy to be quantified. Drivers for cost reduction are identified and quantified. It is shown that optimal turbine placement and sizing can reduce turbine CapEx per unit energy by up to 40% on previously considered locations. The cost of ballast for gravity based foundations is also considered. Initial results show that through appropriate quantification of the effective friction between the gravity based structure and the seabed, the total gravity based structure cost can be reduced by up to 18%. Finally, we demonstrate how vessel costs can be reduced at relatively low flow sites such as Ramsey Sound as a result of longer duration slack tide periods.

The Seminoe Pumped Storage project is a planned reservoir-based energy storage project that will be located in Wyoming, the US. The project will be the first pumped hydro storage project in the state.
Currently, the project is in design and permitting phase.
Black Canyon Hydro, a subsidiary of project developer rPlus Hydro, is the licence applicant for the Seminoe Pumped Storage project.
According to the Final License Application, construction works may start in October 2026, after securing the licence and completion of land lease/ purchase agreements.
Commercial operations are expected to begin in 2031. The cost of construction is estimated to be $2.5bn.
Once complete, the project will with a generating capacity of up to 900MW.
Location and Infrastructure
The Seminoe Pumped Storage project will be located in Carbon County, Wyoming.
The site, around 35miles northeast of Rawlins in Wyoming, was selected as it meets all requirements for a pumped storage project.
A typical pumped hydro energy storage project has two water reservoirs at different elevations. Such facilities generate and store electricity by moving water between the two reservoirs.
The Seminoe project will have two such reservoirs, three variable pump-turbine units in an underground powerhouse, groundwater wells and a connection to the existing electric transmission grid.
The project’s facilities will create an ‘open loop’ hydraulic arrangement.
Seminoe Pumped Storage Project details
The existing Seminoe Reservoir, which has a water storage capacity of nearly one million acre-ft, will be used as the lower reservoir for the project.
Key construction works will involve building the above-ground reservoir and a nearly 30-mile transmission line for the project.
The above-ground reservoir will be located in the Bennet Mountains around 1.7 miles east of the Seminoe Dam around 1,000ft higher than the Seminoe Reservoir.
The upper reservoir will be constructed as a roller-compacted concrete (RCC) water-retaining perimeter structure. The crest of the RCC water-retaining structure will be at an elevation 7,455ft.
The two reservoirs will be joined by underground tunnels, while underground powerhouse will host the pump-turbine units to generate power from water flow.
The same equipment in the powerhouse will also pump water from the lower reservoir back to the upper reservoir to restart the cycle.
The machine hall will also have three generator-motors, and unit spherical shut-off valves upstream of the pump-turbines, control room, stores and other systems for the general functioning of the plant.
When the process will start with a full upper reservoir, the plant would be capable of providing full power output for ten hours before recharge.
The project is expected to create up to 500 high-skilled construction jobs over three to five years. Once operational, the project will employ 35 people in full-time skilled positions.
The power generated by the project will be delivered through a new 30-mile transmission line that will connect the project to electric power company PacifiCorp’s existing Aeolus Substation.
Two 500kV circuits from the underground gas insulated switchgear will transfer power through the low-level cable tunnel up the cable shaft to a take-off structure at the surface.
Subsequently, two separate 500kV overhead primary transmission lines will evacuate power to Aeolus Substation, located 30miles to the southeast of the project.
The overhead transmission system will transverse through Bureau of Land Management (BLM) and private lands.
In April 2020, Black Canyon Hydro filed a Notice of Intent to File License Application, Pre-Application Document (PAD) and Request to Use the Traditional Licensing Process (TLP) with the Federal Energy Regulatory Commission (FERC), the agency for non-federal hydropower projects in the US.
The use of the TLP was approved in June 2020.
Study plans were developed and distributed to stakeholders for comment in March 2021.
According to rPlus Hydro, detailed engineering and environmental studies will continue through approximately 2024.
rPlus Hydro announced the submission of the Draft License Application for the project in June 2022 to Wyoming and Federal agencies.
This was followed by the submission of the Final License Application to the Federal Energy Regulatory Commission (FERC) in January 2023.
In October 2021, rPlus Hydro selected Stantec to conduct a detailed feasibility study for the Seminoe Pumped Storage project.
The scope of work included identifying the alternative intake and outlet structure types; location and type of upper reservoir to complete the pumped storage scheme.
Stantec also performed a geotechnical investigation to support the feasibility design of the underground facilities, identified pump-generating equipment and transmission line route, assessed project constructability and offered an opinion on probable construction cost.
Engineering company HDR is also serving as a project partner.

The Tato II project is one of the largest hydro investment in Arunachal Pradesh.
Located in the West Siang district on Siyom river, the Tato II project would consist of four units of 175 MW each.
The project is set to generate annual design energy of over 3,000 MU with an annual load factor of over 50 per cent, which is one of the highest amongst hydro projects in the country.
Tato is designed to operate as a peak power station, and a power purchase agreement (PPA) has been signed with the BSES Rajdhani Power and BSES Yamuna Power for sale of power to the power-starved Delhi region.
A subsidiary of Reliance Power, the Tato Hydro Power Pvt Ltd came into being to implement a hydroelectric power project in Arunachal Pradesh.
The Tato II project envisages an estimated investment of Rs 6,000 crore and is expected to be commissioned within six years from zero date.
The levelised tariff for the project is expected to be competitive due to the high plant load factor and run of the river structure of the project.
Levelised tariff in the power sector essentially refers to the average fixed and variable tariff over the entire term of the PPA.

Optimization of Hydropower Generator Performance using Neuro-Fuzzy Scheme
- Post by: airjournals
- January 13, 2021
- Comments off
In this paper, Neuro-fuzzy software tool was used to ensure a design of an optimized hydropower plant model. It was used to estimate the size and technical data in a hydraulic turbine. The neural network software was imbibed into the fuzzy logic controller. Input data of this software are hydraulic site conditions, desired operating parameters namely, water level and flow rate, as well as the desired arrangement. The designed adaptive power stabilizers based on artificial neural networks (ANNs) and Fuzzy logic are meant to adapt themselves to the operating conditions based on input-output response of the system. Result analyses were carried out using Neuro-fuzzy software tool in MATLAB to ensure optimal turbine rotational speed is maintained at a desired real-time response. The real-time controller emphasizes the robustness of Neuro-fuzzy application of the scheme for steady-state rotational stability for turbine spinning in a hydropower system.

Current South Park Conveyance study area; boundaries may change based on technical feasibility.
Seattle Public Utilities is currently working on three stormwater projects in northwest South Park's lower industrial basin to reduce flooding and improve water quality in the Lower Duwamish Waterway.
The South Park Conveyance project will complete design for a new stormwater collection system in roadways that don't currently have one. Scope and budget will ultimately determine which roads will receive new drainage systems. Selected roadways will be rebuilt to ensure they drain into the new inlets and catch basins.
We are also planning two additional projects in the lower industrial basin:
The South Park Conveyance project is supported in part with funding from the King County Flood Control District.
The South Park Conveyance project is a joint effort with SDOT. The project is currently in the design phase for improvements to the drainage system and streets. The joint project team is working with technical consultants to determine the best approach and sequencing for the planned improvements.
In 2017, we gathered feedback from lower industrial basin businesses and residents on how they utilize the right-of-way, drainage and flooding issues they experience, and SPU’s proposed plan. We will use this feedback to inform drainage system design.
SPU is analyzing and planning drainage improvements for the entire project area, but the 2018-2023 budget is not sufficient to complete all the work. The plan will include all the work, along with a phased approach for full implementation. The initial phase of construction will be based on available budget.
When complete, this project will work in tandem with the flood control pump station to reduce flooding in the industrial and residential areas in the northern part of South Park. The pipe improvements will collect and convey flows to the existing drainage system and lessen overall flooding. The drainage system will direct stormwater to the flood control pump station, which will pump stormwater to the Lower Duwamish Waterway, and to the future water quality facility

Vortechs is a below-ground, engineered stormwater treatment device
that combines swirl concentration and flow controls into a single
treatment unit. Vortechs is ideal for capturing and retaining trash,
debris, sediment, and hydrocarbons from stormwater runoff. The Vortechs
system’s large swirl concentrator and flow controls work together to
create a low energy environment, ideal for capturing and retaining
particles down to 50 microns.
How Vortechs Treats Stormwater
- Untreated stormwater enters the Vortechs swirl chamber through an inlet pipe.
- The swirling motion of the water within the chamber promotes
gravitational separation of solids which settle on the chamber floor.
- Stormwater exits the swirl chamber, where a baffle wall traps floatables and hydrocarbons.
- Stormwater flows under the baffle wall into the flow control chamber which contains separate flow controls for peaks and low-intensity flows that are designed specific to project requirements.
- Treated stormwater flows to the outlet chamber and exits via the outlet pipe.


TVA's series of dams and reservoirs is well designed to hold back floodwaters as well as to provide power to the citizens of the Valley.
The space allocated for flood storage in the TVA reservoir system varies with the time of year and potential flood threat. From January 1 through March 15, the system has the capacity to store about 11 million acre-feet of water—or a volume equal to one foot of water covering 11 million acres of land. A capacity of about 5 million acre-feet is maintained during summer to reduce flooding caused by summer storms.
Flood Storage Above Chattanooga
Chattanooga is the most flood-prone city in the Tennessee Valley, and the reservoir system in the eastern Tennessee Valley was primarily planned to protect it from flooding. At least one reservoir was built on each of the five major tributary rivers above Chattanooga with enough space to store floodwaters from large storms in the drainage areas above them.
These seven reservoirs do the main work in controlling floods:
- Norris Reservoir on the Clinch River
- Fontana Reservoir on the Little Tennessee River
- Douglas Reservoir on the French Broad River
- Cherokee Reservoir on the Holston River
- Chatuge, Nottely and Hiwassee reservoirs in the Hiwassee River basin.
Three main-river reservoirs above Chattanooga—Fort Loudoun/Tellico, Watts Bar and Chickamauga—provide additional, limited storage capacity. Together, all TVA reservoirs above Chattanooga can store about 5 million acre-feet of water during the winter flood season.
Flood Storage Below Chattanooga
Kentucky Reservoir, near the mouth of the Tennessee River, has 4 million acre-feet of flood storage space during the winter and early spring. This represents more than 40 percent of the flood storage in the entire TVA reservoir system. This capacity can be used to reduce flood crests on the Mississippi River at Cairo, Ill., by as much as two to three feet.
Three other main-river reservoirs upstream from Kentucky but below Chattanooga—Pickwick, Wheeler and Guntersville—provide about 1 million acre-feet of storage space. This is used to supplement storage in Kentucky Reservoir and to reduce flooding immediately below these dams.
Storage space in main-river reservoirs is limited by topography and the requirement in the TVA Act for a 9-foot waterway for commercial navigation from the beginning of the Tennessee River at Knoxville, Tenn., to its mouth at Paducah, Ky.


Check valve is also known as one-way valve or non-return valve. This kind of valve is automatically opened and closed by the force generated by the flow of medium in the pipeline. A check valve is an automatic valve, and mainly applied to the pipe with medium flows in one direction to prevent accident. 3d video xxx mainly manufactures four types of the check valve: swing check valves, pressure sealing swing check valves, dual plate check valves and tilting disc check valves.
1. As the channel within the valve is in streamline form, the flow resistance of the swing check valve is smaller than that of the lifting check valve. It's suitable for low flow and large-caliber applications without frequently change in flow. However, it's not suitable for pulsating flow for sealing performance poorer than that of the lifting check valve.
2. A swing check valve is suitable for various working conditions of pipeline for petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry.
3. The swing check valve is suitable for the clean medium like water, oil, steam, acid medium, but not suitable for medium with solid particles and great viscosity.
From the working performance point of view, pressure sealing bonnet valve has better sealing when facing the greater pressure within the working pressure range. It is mainly used in working conditions above 900lbs.
The center vertical pin shaft. When the valve is open, the resultant force of fluids is on the center of sealing face of the disc, while the point of action of counter spring support force is on the center of disc surface so that the root of the disc opens firstly. It avoids wearing of the sealing surface of the old conventional valve when the valve opens, and increases the persistence of valve seal.
When the flow slows down, the counter force of the torsion spring makes the disc moves to the valve seat, and the valve is in slow off stage. When fluid flow backwards, the closing speed of the disc is correspondingly increased and it enters the rapid closing stage under the force of backflow fluids on the disc and counterforce of the torsion spring. The influence and harm of water hammer is effectively reduced. When closed, the spring force closes the top of the disc firstly so that the root of the disc is prevented from being bitten to guarantee longer service life of valve sealing surfaces.
The API 594 single disc wafer check valve is a single disc swing wafer connecting check valve that prevents backflow of the medium. They are all ultra-thin check valves. The single disc swing wafer connecting check valve is designed to be connected through the wafer. Stainless steel or stellite build-up welding may be applied to sealing surfaces of the valve body and the disc. The valve is suitable for the clean medium, and not suitable for medium with solid particles and great viscosity. The main merit of the tilting disc check valve is that it overcomes shock and water hammer in operating condition of swing check valves and lifting check valves to realize shock-free operation.


Talk by Jim Crossley: Development of Grimwith Reservoir
February 24 @ 19:30 - 21:00
Abstract: Grimwith Reservoir is situated on the River Dibb, a tributary of the River Wharfe, some four miles east of Grassington. The illustrated account describes its development from the construction of the first reservoir on the site in the mid-1800s, to provide compensation for water abstractions taken for supply from other areas of the River Wharfe catchment, to its subsequent extensive enlargement commissioned in 1983, to support new and existing public water supply abstractions from the River Wharfe downstream.
The presentation includes a detailed description of the planning and design of the enlarged reservoir supply scheme, as well as addressing with photographs, the problems encountered and progress made on the construction of the enlarged earth dam. The associated river abstraction and water transmission works are also briefly referred to.


Pumping system operating efficient operation is important to reduce operating power cost. Considering a typical 5 year lifecycle of 100KW and above pumps, spent on power contributes to more than 90% of total ownership cost. Therefore it is important to consider operating efficiency of pump. Pump efficiency is always a major consideration while pump procurement, but because of no of reasons in many cases pump efficiency drops while operation. lets check, How to operate pumping system efficiently.
Reason for efficiency drop can broadly be divided in two categories:-
- Best efficiency point shift as per system requirement.
- Pump efficiency deterioration.
Let us try to estimate pump operating efficiency step by step:
STEP-1 Measure and collect pump system data as below
- Operating Flow
- Operating differential Head. (Discharge head – suction head)
- Fluid type
- Motor power withdrawn and shaft power.
- Pump curve
STEP-2 , After collecting data measure pump efficiency
Efficiency of pump is calculated by
Pump efficiency = Ph(kw) / Ps(KW) X 100
Where, Ph(kw) is hydraulic power & Ps(KW) is shaft power
Ph (KW) = ( (Sprg X Q ) X H X g) / 3600
- Q = capacity in m3 /
- spgr = specific gravity (water =1)
- H = differential head in mtr
- g = gravitational acceleration in m / sec 2 (g=9.8)
Ps (KW) = motor measured power X motor efficiency
STEP 3 Example with a typical pump data
Data collected as per below format and pump efficiency calculation
Pump flow 750 m3/hr,
Differential head = 37 mtr,
Measured power = 109 KW
Motor efficiency = 93%.
Ph (KW) = 750X37X9.8/3600 = 75.54 KW
Ps (KW) = 109X.93 = 101.37 KW
Pump efficiency =75.54 / 101.37 =74.5%
STEP 4 Identification of Problem
|Sr. No.||Case||Condition||Reason for efficiency drop|
|1.||Pump efficiency is low||If pump flow, head and power follows pump characteristics curve.||Best efficiency point shift as per system requirement.|
|2||Pump efficiency is low||If pump flow, head and power does not follows pump characteristics curve.||Pump efficiency deterioration|
STEP 5. Solution to pump efficiency drop
|Sr. No||Reason for efficiency drop||Condition||Solution||Disclaimer|
|1||Best efficiency point shift as per system requirement.||Flow is high, Head is low||Pump needs to be replaced with suitable design.|
|2||Best efficiency point shift as per system requirement.||Flow is low (constant) , head is high||Impeller trimming may be done.||Impeller tripping will shift pump operating condition to Best efficiency point|
|3||Best efficiency point shift as per system requirement.||Flow is low( But Variable) , head is high||VFD can be planned|
|4||Pump efficiency deterioration||Flow is low, Head is low||Wear ring clearance increase.||Need to replace wear ring|

"OMAHA, Nebraska -- Releases from six Missouri River reservoirs, already at historic levels, will be increased again this month, say water managers with the U.S. Army Corps of Engineers.
Reservoir storage is now near capacity after a year's worth of rain fell in the Upper Missouri River Basin during the past few weeks. In addition, snowpacks measured at 140 percent of normal in Montana, northern Wyoming and the western Dakotas are melting, contributing to unprecedented runoff to the Missouri River and its tributaries.
Water managers expect significant flooding in cities, towns and agricultural land along the Missouri River in North and South Dakota. Many stretches of the river from Sioux City, Iowa to the Mississippi River will rise above flood stage. "

Ultrasonic Water Level Controller with 8051 Microcontroller In our day-to-day life, we frequently use different types of sensors in various electronic appliances such as proximity sensor-mobile phone, motion sensor-automatic door operating system, temperature sensor-automatic fan speed controller, LDR sensor-automatic street light system or automatic outdoor lighting system, and so on. Similarly, to avoid the overflow of water in overhead tank or water container we can use the ultrasonic sensor based electronic circuit. This article discusses about ultrasonic water level controller using 8051. Water Level Controller Water level controller, the name itself indicates that an electronic device or circuit kit used for controlling the water level can be termed as a water level controller. It is difficult to know the level of water in the overhead tank such that wastage of water can happen frequently. To conserve water, avoid overflow of water in the overhead tank which may cause loss of water, loss of electrical power, etc.,. Thus, ultrasonic water level controller using 8051 microcontroller is an innovative electronics project application for controlling water level. 9-Level Overhead Water Tank Indicator 9 Level Overhead Water Tank Indicator Project by www.edgefxkits.com 9-Level overhead water tank indicator project is used to display the level of water in the overhead tank using 7-segment display. The project block diagram is shown in the figure below which consists of various blocks such as a power supply block, water container, priority encoder, transistor, BCD to 7-segment decoder, 7-segment display, etc.,. 9 Level Overhead Water Tank Indicator Project Block Diagram by www.edgefxkits.com The sensor is placed such that the ground terminal of the sensor is kept at the tank bottom and based on the sensor signals sent to priority encoder. The encoder will generate BCD outputs which are fed to the BCD to 7-segment decoder. Thus, the 7-segment display is used to display the amount of water or water level the tank using a scale of 0 to 9. This project can be further enhanced using automatic turn on or off motor for maintaining required water level in the overhead tank. Do you want to design a water level controller on your own at home? In our day-to-day life we use overhead water tank, if water level controller is designed, then we can save water and electrical energy also. The water level controller block diagram is shown below figure which consists of water sensors, transistor, level indicator, battery. Overhead Water Tank Level Indicator The water level sensors used in this project are insulated copper cables, three water sensor cables are used for demonstrating three levels of water, such as empty, half and full levels of water in overhead tank. Three NPN transistors and resistors are used in this project along with water level sensors for analyzing water level by switching ON the LEDs in ascending order. This project can be further enhanced for controlling the motor pump which is used to pump water to the overhead water tank, which can be termed as automatic water level controller using 8051 microcontroller. Ultrasonic Sensor based Water Level Controller using 8051 Microcontroller Similar to 9-level overhead water tank indicator, the ultrasonic sensor based water level controller using 8051 microcontroller project is an advanced and innovative electronics project designed for displaying water level in a tank and also control pump motor accordingly. The water level controller project block diagram is shown in the below figure. Water Level Controller Project Block Diagram by www.edgefxkits.com As represented in the above block diagram, there are various blocks such as a power supply block, microcontroller, relay driver, LCD display, relay, lamp (for demonstration purpose lamp is used instead of a motor), etc.,. The power supply block consists of a transformer used for stepping down the voltage from 230V to 12V AC, rectifier bridge used to rectify the voltage (convert AC voltage to DC voltage), IC 7805 voltage regulator used to maintain a constant output voltage for the circuit. This project circuit consists of microcontroller and components that require DC voltage around 5V, hence, power supply block is used for obtaining required supply to the circuit. The project is designed for controlling the overhead tank water level by controlling the motor operation using a relay. The scale from 0 to 9 is considered for measuring and indicating the water level in the tank. The sensor ground terminal is placed at the bottom of the tank which will give signal to the microcontroller whenever the water level reaches maximum level in the tank. Water Level Controller Project by www.edgefxkits.com Based on the signal received from the water level sensors, the microcontroller generates control signal for operating relay connected to the motor (here it is connected lamp instead of a motor). Thus, the relay will shut down the motor for controlling the water level in the tank. The water level can be indicated over the LCD display.

The design capacity of a water supply can be derived from the peak factor. In this research, four different methods were used to determine the peak factor more precisely. Applying Method 1 could result in the design capacity being underestimated, by designing the lower part of the pipeline to apply the peak factor to the whole area. Applying Method 2 could overestimate it by 10–30% in the upper part of the pipeline by dividing the sum of the regional peak factors according to the ratio of peak day demand to the region. Applying Method 3 underestimates the design capacity in small areas, while it could overestimate it in large areas. Finally, Method 4 gives optimum results for the peak factor for estimating the design capacity.

KARIBA Dam Rehabilitation Project is on course with some specific works which will improve power generation in Zimbabwe and Zambia set to be completed next week.
The completion of the works will pave way for the lifting of power generation restrictions on Zesco Limited of Zambia and Zimbabwe Power Company (ZPC) which had been reduced to six (6) hours on a few selected dates.
In a statement, Zimbabwe River Authority Chief Executive, Engineer Munyaradzi Munodawafa said the request to reduce power generation will end after the completion of specific works on January 24.
He said the Kariba Dam Rehabilitation Project is expected to be completed by 2024 adding that it will ensure the long-term safety and reliability of Kariba dam.
Meanwhile, the Zimbabwe River Authority says the water inflows into Kariba Dam only started improving this month due to the late onset of the rainy season.
The authority is however hopeful that the dam levels will continue improving in light of the Rainfall Season Outlook which predicted normal to above normal rainfall in the SADC region.

Common valve selection instructions
The butterfly valve is suitable for occasions with large caliber (such as DN>600mm) and short structural length requirements, as well as need to adjust the flow rate and fast opening and closing requirements, generally used for temperature ≤80°C, pressure≤1.0MPa water, oil and compressed air medium.
Because the butterfly valve relative to the gate valve, ball valve pressure loss is relatively large, so the butterfly valve is suitable for piping systems with poor pressure loss requirements.
Ball valve selection instructions
Ball valves are suitable for low temperature, high pressure, high viscosity media. Most ball valves can be used in media with suspended solid particles and can also be used in powdered and granular media depending on the material requirements of the seal.
The full-channel ball valve is not suitable for flow regulation, but it is suitable for occasions requiring quick opening and closing, which is convenient for emergency cutoff of accidents; usually, the sealing performance is strict, wear, shrinkage passage, quick opening and closing action, high pressure cutoff (large differential pressure).
Ball valves are recommended for pipes with low noise, gasification, low operating torque and low fluid resistance.
The ball valve is suitable for light structure, low pressure cut-off, corrosive medium; ball valve is also the most ideal valve for low temperature and deep cooling medium, and the low temperature medium pipe system and device should use the low temperature ball valve with bonnet.
When the floating ball valve is selected, the valve seat material should bear the load of the sphere and the working medium. The large-diameter ball valve needs a large force during operation, DN≥200mm ball valve should be in the form of worm gear transmission; the fixed ball valve is suitable for occasions with larger caliber and higher pressure.
In addition, the ball valve used for process highly toxic materials and combustible medium pipeline should have fireproof and anti-static structure.
Gate valve selection instructions
In general, the gate valve should be preferred. In addition to suitable for steam, oil and other media, the gate valve is also suitable for media containing granular solids and high viscosity, and is suitable for valves for venting and low vacuum systems.
For media with solid particles, the gate valve body should have one or two purge holes. For low temperature media, low temperature special gate valves should be used.
Check valve selection instructions
Check valves are generally suitable for cleaning media and should not be used for media containing solid particles and high viscosity. When≤40mm, it is advisable to use a lifting check valve (only allowed to be installed on horizontal pipes). When DN=50~400mm, it is advisable to use a swing-type lifting check valve (can be installed on both horizontal and vertical pipes, such as Installed on a vertical pipe, the flow of the medium is from bottom to top).
When DN≥450mm, buffer type check valve should be used; when DN=100~400mm, the clamp type check valve can also be used. The swing type check valve can be made into a high working pressure, and the PN can reach 42MPa. Depending on the material of the housing and seal, it can be applied to any working medium and any operating temperature range.
The medium is water, steam, gas, corrosive medium, oil, medicine, and the like. The media operating temperature range is between -196 and 800°C.
Globe valve selection instructions
The shut-off valve is suitable for pipelines with less demanding fluid resistance, that is, pipelines or devices with little consideration for pressure loss, and high-temperature and high-pressure medium, suitable for medium pipes such as steam with DN<200mm.
Small valves can be used with shut-off valves, such as needle valves, instrument valves, sampling valves, pressure gauge valves, etc.
The shut-off valve has flow regulation or pressure regulation, but the adjustment accuracy is not high, and the pipeline diameter is relatively small, and a shut-off valve or a throttle valve should be used.
For highly toxic media, a bellows-sealed shut-off valve should be used; however, the shut-off valve should not be used for mediums with high viscosity and media containing particles, and should not be used as valves for venting valves and low vacuum systems.

Ever wonder what it takes to build a dam? At Fast Pulse, Nelspruit’s leading plant hire company, we know the ins and outs of which equipment will best serve the purpose of successful dam construction and in our latest blog, we explore this fascinating topic.
In South Africa, the construction of dams is of vital importance as South Africa does not have a lot of water. Most large dams are constructed in such a way that they are capable of bearing rails or even bridges.
Dams are used to channel water supply as well as store it. A lot of dams are constructed on rivers and without the use of heavy construction equipment it would be near impossible for the engineers to build these huge dams that can hold the tons of water under pressure.
Before dams are built, the purpose that that dam is going to serve is carefully planned. Some of the reasons for building a dam are as follows:
- Providing protection from flood, by channelizing water supply
- Reserving water or making water reservoirs at the backwater dams
- Creating shipping channels as lateral dams
- Producing hydroelectricity.
The construction equipment used to build a dam, whichever your chose, is always the same.
List of heavy construction equipment needed for dam construction include:
The first step when building a dam on a river is to divert the river away from the construction site. Once the river has been successfully diverted the ground where the dam is going to be can be excavated.
After the excavators have done their work the loaders get called in to remove the excavated ground from the construction site. Loaders remove the ground to another area so that the construction site is completely clear of debris. High power pumps come in after the loaders to remove all water from the entire area to enable further construction.
Once dried, the compactors are brought in ensure that the ground is suitable compacted before construction can start. Often several different kinds of compactors are used to get the area completely compacted and safe for the construction of a dam.
- Ready-mix concrete trucks
Because huge amounts of concrete gets used in the construction of a dam, ready-mix concrete trucks are brought in to mix and fill the area with concrete. With the construction of very large dams, mixing plants are often built on the construction site.
Large amount of water is stored in dams and so engineers make plans for dams with either gates in them or an outlet for excess to be able to flow away safely once the dam is full. Once the concrete is dried up entirely, the original path of the water is channelled back to its original path. The dam is now ready for either storing water or holding water or in cases of huge dams, generating hydro-electricity.
