Pinhook Road Overlay
Public Works Project Number: 1900
Project Length (miles): 1.2
Parish District: 4, 5
Construction Estimate: $2,300,000.00
Project Cost: $2,500,000.00
Project Type: Traffic, Roads & Bridges
The Pinhook Road Overlay project is a road rehabilitation project that aims to improve the condition and functionality of Pinhook Road from S. College Rd. to E. University Ave. One of the primary components of the project is the improvement of the drainage system along the roadway. The existing storm drain system is in poor condition and no longer functioning efficiently. The existing catch basins and manholes will be removed, and new catch basins and manholes will be installed at strategic locations to improve the flow of stormwater runoff, prevent flooding, and reduce erosion. In addition to the new catch basins and manholes, trench drains will be added to improve drainage along the road. Trench drains are important for efficiently capturing and conveying stormwater runoff. The trench drains will be installed at appropriate locations along the roadway to ensure maximum effectiveness. The project will also include drainage improvements such as the installation of pipes and culverts to channel water away from the roadway. The team will work to minimize disruptions to the community during the construction process by scheduling work during off-peak hours and minimizing lane closures.
The graphic below provides a conceptual view of the proposed improvements that will be considered for the project.
DRAINAGE AND GREEN INFRASTRUCTURE CONSIDERATIONS
To address the drainage concerns, the construction team will be removing the existing catch basins and manholes that are in poor condition and replacing them with new ones. This will help to ensure efficient drainage of stormwater runoff and prevent flooding along the road. Furthermore, the project will also replace the existing pipes and install new trench drains to further improve the drainage system along the road. The trench drains will be designed to effectively capture and convey stormwater runoff, reducing the risk of flooding and erosion.
To address the green infrastructure concerns, the team will work to incorporate sustainable design practices into the project. For instance, the construction team may consider adding vegetated swales or bio-retention areas to help filter and manage stormwater runoff, promoting healthier soil, and reducing the heat island effect.
Considerations have been identified and must be reviewed and potentially addressed. Upon research, very minimal impact to the environment will be done with this project.
*Note that this is not exhaustive of possible future environmental considerations.
A preliminary assessment of the project area is provided for the utilities listed below. Potential utility relocation costs will be included in the project budget if the infrastructure is located within the utility’s own servitude.
RIGHT OF WAY CONSIDERATIONS
The current project under consideration does not require any right-of-way acquisition.

SUBSTITUTE PUMPS WITH ELECTRIC
The submersible pumps with propellers are a range of axial flow submersible pumps and are suitable for raising large volumes of water at relatively low level differences. Common applications include drainage of flooded water, irrigation, water supply for artesian fountains, and cooling water supply.
Submersible pumps with axial and semiaxial propellers are specially designed to lift high flow rates at small and medium heights. Reliability and high efficiency make them suitable for pumping rainwater collected, drainage, drainage, rice fields, water purification stations, aquaparks (water fun parks), marine water, etc.
The pumps have a solid structure, and they are supplied with a sturdy classical shaft offering solid and compact equipment. Insulation between the engine and the hydraulic end is made by two high-end mechanical gaskets, and the oil bath. The motor is three-phase, short-circuit rotor with IP 68 and insulation class F for 155 degrees Celsius.
The installation is very simple, when the pump is inserted into the exhaust pipe, it is supported by its own weight. This range of pumps includes models with flow rates of up to 30000 m3 / hour.


In order to study flow pattern and hydraulic performance of vertical pumping station with bell inlet and worm outlet, which was used by South-to-North water transfers project, the incompressible N-S equations are solved by the control finite volume method. Based on the RNG k-ε model with Wall-Function Law, the SIMPLEC algorithm is applied for the solution of the discretization governing equations. Using multiple reference frames, the flow detail of whole vertical pumping system is attained. The named height of pump is put forward. The numerical hydraulic performance was computed. A good agreement was achieved between predicted data with experimental data on BEP. This type of pumping station will be applied in the East Route Project of South-to-North Water Transfers of China.

Physical modifications to improve a channel’s flow distribution
ABSTRACT A modified approach is suggested to achieve even flow distribution (i.e., the equality of flow distribution) in an open channel in water treatment plant. The suggested approach includes installing
a longitudinal baffle with orifices in the main flow direction. To evaluate the efficiency of suggested model, both computational
fluid dynamics (CFD) model and pilot tests were carried out. The pilot tests, which were scaled down to 1/8 of full scale,
showed that the equalities of the flow distributions in the modified channels were up to 30% higher compared to those in the
conventional channel when the equalities were quantified using the standard deviation of the flow distributions. In addition,
the velocity contours computed by numerical simulation in the conventional full scale channel were compared with the velocity
contours in the remodeled channel in order to verify the more even flow distribution in the modified one than that in the

ABSTRACT: The Reynolds stress model is applied to open-channel flows with vegetation. For the computation of pressure-strain term, the Speziale, Sarkar, and Gatski's model is employed. Mellor and Herring's model and Rotta's model are used for diffusion and dissipation rate of Reynolds stress, respectively. Flow structures of open-channels under two vegetative conditions are simulated, namely submerged and emergent plants. Plain open-channel flows are also simulated for comparisons. Computed profiles are compared with the results from the κ-ε model and the algebraic stress model as well as measured data available in the literature. For the plain open-channel flow and the open-channel flow with emergent vegetation, the Reynolds stress model is observed to simulate the non-isotropic nature of the flows better than the algebraic stress model and the κ-ε model. For the open-channel flow with submerged vegetation, it is found that the Reynolds stress model predicts the mean flow and turbulence quantities best compared with the other models. Sediment transport capacity of vegetated open-channel flows is also investigated by using the computed profiles. It is shown that the isotropic turbulence model underestimates the suspended load seriously.Journal of Hydraulic Research 12/2010; 2004(Vol. 42):3-11. · 1.04 Impact Factor

The sod has been turned on a 114 million euro wastewater project in Athlone.
It took place earlier today by Minister Darragh O'Brien at the site of the new pumping station currently under construction at Golden Island.
The Athlone Main Drainage Project involves the construction of new pumping stations at Golden Island and Coosan West, and almost 3km of new sewers. The existing pumping stations and pipework will be decommissioned and combined sewer overflows will be eliminated at six locations along the River Shannon.
These will be replaced by two new stormwater overflows designed to meet current licencing standards, which Irish Water say will improve water quality and safeguard the environment. The project itself is one of the largest investments by Uisce Eireann to date.
Speaking at today's sod turning Minister Daragh O'Brien welcomed the commencement of work and stated it was pivotal for the future growth and development of the town. Uisce Eireann say they will continue to engage with the local community throughout the duration of the project.

This report documents the development of the Fox River watershed hydrologic model using the Hydrological Simulation Program - FORTRAN (HSPF). The Fox River HSPF model simulates rainfall runoff processes for watersheds adjacent to the Fox River from Stratton Dam to the mouth of the Fox River at the Illinois River. Runoff is simulated from 31 separate tributary watershed models and is used as an input to the mainstem model. Observed flows at Stratton Dam are used as the upstream boundary condition defining inflow from the Fox River watershed above Stratton Dam. Calibration is based on Hydrologic Response Units (HRUs). These units represent homogeneous areas of land use, soil type, and slope. Parameter values from prior calibration of Blackberry and Poplar Creek models were initially used for the same HRUs in the other 29 tributary watershed models and the mainstem model. However, additional calibration was needed to simulate flow at the Fox River mainstem gages accurately. Calibration was simplified to determine model parameters for dominant HRUs covering more than 10 percent of drainage area. The model parameters for dominant HRUs and reported literature values guided development of model parameters for other major and minor HRUs. Parameter values were developed through calibration of the mainstem model using observed flows from United States Geological Survey gages at Algonquin, South Elgin, and Dayton. The Fox River mainstem model was calibrated for water years 1991–1999 and validated for water years 2000–2003. Simulation results are presented in graphics, and model accuracies were evaluated through graphical comparisons and statistical measures such as the Nash-Sutcliffe efficiency coefficient and coefficient of determination. Exceedence probabilities of simulated and observed flows were compared to assess the simulation accuracy for high-, low-, and middle-range flows at three Fox River mainstem gaging stations. The integrated model simulates flow at the mainstem gages adequately based on specified calibration criteria. Model performance for the two pilot watersheds, Blackberry and Poplar Creek, worsened slightly, but overall performance for all seven gaged tributary watersheds improved.

Modeling Gerotor Oil Pumps in 1D to Predict Performance with Known Operating Clearances 2016-01-1081
Engine and transmission oil systems are commonly pressurized by gerotor style pumps, due to their simplistic design and low cost. Gerotor pumps are designed with certain tolerances of the gears and housing, thus creating a tradeoff of lower cost with larger tolerances and higher cost with smaller tolerances. By building a detailed gerotor pump model with a 1D hydraulic flow network, engineers can evaluate pump performance with these tolerances as input and compare to find the optimal design. This paper showcases the ease of building a gerotor model in 1D by using an automated process extracting the key model inputs directly from the pump CAD file. The gerotor pump performance is predicted including flow rate, total power loss, volumetric efficiency, and total efficiency vs. pump speed, pressure rise, clearance tolerances, and temperature, and compared with experiment. A predictive friction model for gerotor pumps is proposed and total torque required to drive the pump is compared directly with experiment. Additionally, an internal leakage model for predicting volumetric efficiency taking into account physical clearance between inner and outer gears, as well as temperature is discussed.

This project consisted of installing new drainage structures; including catch basins, piping and drywells; in a neighborhood area that regularly saw roadway flooding during runoff events. The new structures were installed along 63rd Avenue, near the intersections of Helena Street, Martin Street, and Crestline Street. The goal of this project was to decrease the frequency and extent of roadway flooding and add sediment storage capacity to increase the required maintenance interval of these drainage structures. Construction of this project was completed by NNAC Inc. under the supervision of Spokane County Stormwater Utility in November 2018.
The existing drywells in this area were found to be in a failed state when flooding conditions persisted after cleaning and other maintenance practices were performed. Seven new double-depth drywells were installed with pipe connections from existing drywells. Three new catch basins were also installed at desirable locations to decrease surface flows and add sediment removal capacity prior to water entering drywells. The existing drywells were left in-place to retain available runoff storage volume and add another layer of sediment storage upstream of the new drywells. Funding for this project was provided by the Stormwater Utility and was completed using Spokane County’s Small Works Roster program.

Ft. Patrick Henry Dam, Tennessee
SAM (formerly as HALIS) was contracted to provide simultaneous LiDAR and Imagery acquisition of the Fort Patrick Henry Dam and downstream area. SAM contracted with a survey firm to provide field surveys to be utilized in the calibration of LiDAR data and triangulation of imagery.
Data Acquisition for this project included close coordination with dam personnel to ensure that acceptable downstream water levels were achieved. In order to fly with water as low as possible, SAM alerted dam personnel before flight window so that the dam could be closed. Once the dam was closed, data acquisition had to be completed within a four-hour window, starting 20 hours after closure. SAM completed one flight utilizing a helicopter platform for high density dam scan to be utilized in the construction of a 3D model, and a second fixed wing flight during low water conditions to be utilized in the generation of 1′ contour data and color orthophotography.
Project deliverables included DTM and 1′ contours in CADD format, 3D model of the dam in CADD format, orthophotography in TIFF format, and LIDAR Accuracy report in PDF format.

The excavation of an underground powerhouse cavern at Kidston Pumped Storage Hydro Power Plant in North Queensland, Australia, has begun. This comes approximately 14 months since the implementation of the project began in January 2022.
The project seeks to transform the former Kidston gold mine into a pumped storage hydroelectric power generation facility. It is being carried out by a Joint Venture between McConnell Dowell and John Holland.
Located approximately 270km northwest of Townsville, the plant is the flagship scheme of renewable energy and storage firm Genex. It will form part of a renewable energy hub that also includes 320MW solar and 258MW wind power plants.
Scope of the Kidston Pumped Storage Hydro Power Plant Project in North Queensland, Australia
The project scope involves the conversion of the site’s two existing mine pits into upper and lower reservoirs. It also involves the construction of significant underground infrastructure that includes a large powerhouse cavern and waterway shafts.
The underground infrastructure also includes tunnels that will transfer water between the reservoirs. The water will be used to generate power when solar and wind generation is unavailable.
The Kidston Pumped Storage Hydro Power Plant powerhouse will host two 125MW Andritz hydro reversible pump turbine units. These units will allow the turbines to be used to both generate electricity and pump water for energy storage purposes.
The project is expected to be completed in 2024 while the plants’ operation is expected to begin in early 2025. A new 200km (from Kidston to the East Coast of Queensland) transmission line with 275kV capacity will connect the facility to the main grid.


Funding for flood control outlets on Lake Manitoba and Lake St. Martin announced
June 19, 2018
The project consists of building two approximately 23km-long diversion channels as well as building two bridges and water control structures, a 24-kilovolt distribution line, and adjusting surrounding highway infrastructure.
The governments of Canada and Manitoba will cost share up to $540 million in new flood management infrastructure for the Lake Manitoba and Lake St. Martin outlet channels.
Federal funding of $247.5 million will be provided for the Lake Manitoba and Lake St. Martin Outlet Channels Project, the first project to be funded under the recently launched Disaster Mitigation and Adaptation Fund. Manitoba will provide matching funds in the amount of $247.5 million, plus an additional $45 million in order to complete the project.
The governments of Canada and Manitoba identified the channels project as a major priority, due to severe flooding in the area in 2011 and 2014. These disasters resulted in extensive damage to homes, businesses and infrastructure in the province, as well as emergency evacuations, particularly for communities around Lake St. Martin.
During times of flooding and high-water levels on Lake Manitoba, the new outlet channel will carry water directly from Lake Manitoba to Lake St. Martin. The Fairford River is the natural outlet to Lake St. Martin. The Lake St. Martin channel will move water directly to Lake Winnipeg. The Dauphin River is the natural outlet to Lake Winnipeg from Lake St. Martin.
The project consists of building two approximately 23km-long diversion channels: the Lake Manitoba Outlet Channel will run north from Watchorn Bay on Lake Manitoba to Birch Bay on Lake St. Martin; the Lake St. Martin Outlet Channel will run northeast from Lake St. Martin to Lake Winnipeg south of Willow Point. The project also involves building two bridges and water control structures, a 24-kilovolt distribution line, and adjusting surrounding highway infrastructure.
The project will significantly reduce the flood damage experienced by First Nations located along Lake St. Martin, complementing other regional flood protection infrastructure to ensure a more comprehensive provincial water control network that enables the province to effectively manage flows from the Assiniboine River and Lake Manitoba watersheds spanning Manitoba, southeast Saskatchewan and northeast North Dakota.
Together, the channels will allow Manitoba to regulate lake levels and provide flood protection to individuals, businesses, communities and farmland around Lake Manitoba and Lake St. Martin. Once completed, this work will significantly enhance the region’s ability to regulated water levels on both lakes and protect local Indigenous and non-Indigenous communities from flooding.
The new Lake Manitoba outlet channel is designed with a capacity of 7,500 cubic feet per second (cfs) and the Lake St. Martin channel will carry approximately 11,500 cfs at capacity.
The current capacity of the Lake St. Martin Emergency Outlet Channel is approximately 4,000 cfs. The existing single Lake St .Martin emergency channel to Lake Winnipeg will be available on an emergency basis during construction. After the permanent channels are completed, the existing emergency channel will be modified for environmental support purposes, which are still being defined and developed.
KGS Group was the prime consulting engineer working for the Ministry of Infrastructure and Transportation on the studies and recommendations for flood mitigation in the province.
The current proposed channel alignments are a result of evaluating several options for each channel. Construction of an access road to the Lake St. Martin construction area is underway. The remainder of construction could start as soon as fall 2019.

Cla-Val offers turnkey solutions for terminals, bulk storages and airports, including a complete range of fuel system control valves and ground fuelling equipment. In fuelling systems, each of our fuelling control valves performs a unique function in the system including flow limiting, surge protection, fuel shut-off, level control, back pressure control, pressure reducing.
Cla-Val valves, nozzles, couplers and accessories play a vital role in commercial and military fuelling applications throughout the world.
The Cla-Val model 40-36 rate of Flow and Fuel Shut Off Check Valve is a hydraulically operated, pilot controlled, diaphragm actuated control valve that limits flow to a preselected maximum rate, regardless of changing line pressure. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is assured as very small changes in the controlling differential pressure produce immediate corrective action of the main valve. The orifice bore is factory sized based on flow rate to ensure proper control valve performance. Flow rate adjustments can be made by turning an adjusting screw on the pilot control. The fuel shut off feature closes the main valve when remote pressure from a Cla-Val Model CFF18T-H2 or CFF21-H2 flanged float control is admitted into the cover of an auxiliary Hytrol. The integrated chack feature protects upstream equipment like filter separators by admitting downstream pressure into the main valve cover chamber, closing the main valve upon pressure reversal.

Submersible sand dredging pump daily failure and maintenance measures are as follows:
- Why does the vacuum table indicate a high vacuum and that the pump does not absorb water.
Reason: Because the diving sediment pump bottom valve does not open or is seriously blocked. Suction pipe has big resistance. Absorb height is too high.
Treatment: Check the bottom valve flexibility, remove the plug. Try to make the suction line simple. Reduce the height of the submersible sand pump.
- submersible sand dredging pump power consumption is too large.
Reason: the volume chamber packing pressure too tight, filling room heating. Sand pump impeller wear. Pump water supply is too large.
Remedy: Relax the packing gland. Replace the wearable alloy material impeller. Turn down the break valve, reduce the flow.
- Long-term operation cause the bearing heat when working
Reason: submersible sand pump bearing lack of oil or oil viscosity too much impact lubrication. Sand pump bearing wear gap is too large. The pump and the motor are not concentric.
Treatment: add lubricating oil. Change better oil or oil with low viscosity. Replacement of new bearings. Adjust the sand pump and motor, to ensure concentric.
- Submersible sand dredging pump sound abnormal vibration, can not pump the mixture of water and sediment.
Reason: Suction pipe resistance is too large. Absorbance is too high. There is air into the suction pipe. The temperature of the conveying liquid is too high or the conveying particles are too large to block the mechanical seal.
Treatment: Check the submersible sand dredging pump suction pipe with or without plug. Clean the bottom valve, lower the liquid temperature or lower the suction height.
Submersible slurry pump is made of wear-resisting alloy steel with advanced structure. It has the characteristics of high efficiency, abrasion resistant, automatic coupling and long life span etc. It is powerful to discharge solid particles like sand and coal cinder ,mainly used on the dredger, ship or boat for dredging and mineral waste residue transfer, bottom with extra agitator greatly improve the work efficiency


Gwayi-Shangani Dam Project Takes Off
Image Credits: The Herald
Implementation of the Gwayi-Shangani Dam project in Matabeleland North Province has resumed following the allocation of resources by Treasury, President Mnangagwa said yesterday. A major component of the National Matabeleland Zambezi Water Project (NMZWP), the Gwayi-Shangani Dam project has been in limbo for years due to lack of funding.
The project requires an estimated $53 million.
President Mnangagwa told thousands of people as he officially opened the 59th edition of the Zimbabwe International Trade Fair (ZITF) that the dam project was significant in power generation as well as water supplies for the region.
“The construction of the Gwayi-Shangani Dam has resumed in earnest following the requisite budgetary allocation, and is expected to generate power and also increase water supply and availability to the region,” said the President.
Last month, President Mnangagwa pledged to ensure the project was completed by next year, as well as speed up other outstanding projects in Matabeleland.


Happy Valley Underground Stormwater Storage Scheme wins 2012 IWA Project Innovation Awards
4 July 2012
The Drainage Services Department (DSD)'s Happy Valley Underground Stormwater Storage Scheme (HVUSSS) has won the 2012 International Water Association (IWA) Project Innovation Awards (East Asia Regional Awards) in the Planning Category. The IWA established the Project Innovation Awards Programme in recognition of excellent and innovative water engineering projects around the world.
The DSD has always been committed to adopting sustainable flood prevention proposals. The HVUSSS is Hong Kong's first application of the movable crest weir system with supervisory control and data acquisition. One of its advantages is more effective collection of excess stormwater, which results in a smaller storage tank. The shallow tank design also enables the water pump to consume less energy, as well as reducing construction time and costs. The HVUSSS answers problems related to flood prevention and environmental protection.
The project is Hong Kong's first example of applying state-of-the-art hydraulic modelling techniques including 1-D and 2-D hydraulic models for drainage network and overland flow. It also makes use of a 3-D computational fluid dynamics model to analyse the hydraulic performance of particular parts of the system in an effort to increase the precision of the flood prevention design.
Construction of the HVUSSS commenced in 2011. Upon the completion of Phase 1 in early 2015, residents of Happy Valley and the vicinity will benefit from an enhanced level of flood prevention. The project is scheduled for completion in early 2018 and its estimated cost is HK$1 billion. On completion, the flood prevention level is expected to be further upgraded to the ultimate design level.

Safe Harbor Dam
The Safe Harbor Dam is a concrete gravity dam on the lower Susquehanna River with an associated hydroelectric power station.
After the failure of an existing concrete skimmer wall spanning nearly 50 ft., Providence was asked to design a replacement wall. In addition to accounting for design loads such as differential water levels, ice, wind, earthquake, waves and debris, maximum wall thickness and wall weight were factored into the design due to load restrictions during installation. To satisfy all constraints, the final design consisted of (3) 8 ft. tall stackable wall segments of steel channel frames with upstream and downstream plated faces. Connections to support piers on either end were designed to be ‘breakaway’; therefore, if loads in excess of design loads are ever encountered, the connections will fail, but the wall and piers will remain intact and reusable.

Near Real-Time Optimization of Multi-Reservoir during Flood Season in the Fengman Basin of China
- Wang, Fuxing, Saavedra Valeriano, Oliver C., Sun, Xinguo
- Water resources management 2013 v.27 no.12 pp. 4315-4335
- energy, floods, hydrologic models, China, Japan
- This study aims to develop a multi-objective optimization model in a multi-reservoir system during flood season using Numerical Weather Predictions (NWPs) outputs (short forecast). The optimization model was coupled with the Water and Energy Budget-based Distributed Hydrological Model that was used to forecast the reservoir inflows. The model was forced by 8-day lead time global deterministic NWPs by Japan Meteorological Agency. The reservoir objective function was established by considering the reservoir and upstream safety, downstream safety and future water use. The model was applied to the Baishan-Fengman multi-reservoir system of Northeast China. The results have demonstrated the model with high efficiency in optimizing reservoir objectives for all of the reservoirs. The sensitivity of the system to lead time and decision time were investigated. With the decreasing of lead time, the dam release peaks decrease and the end water levels increase. This is mainly due to the fact that the model with longer lead time needs to keep storage capacity for detected floods during long lead time period. The variation amplitude of dam releases and water levels decrease with the increasing of decision time due to the smoothing of floods and dam releases during long decision period. The model is easy to operate and is able to be coupled with other hydrological models or earth system models.


The state-owned electricity producer of Montenegro - Elektorprivreda Crne Gore (EPCG) - for the first time in 40 years received the right to build a hydroelectric power plant. The construction of the Komarnitsa HPP will cost between 260 and 290 million euros.
The first large hydropower project in modern Montenegro will have an installed capacity of about 172 MW and produce 213 GWh per year.
The hydroelectric power station will be built in the middle part of the Komarnitsa river near the town of Lontsi - 45 km upstream of the operating Piva PSP (installed capacity 342 MW). The project envisions a 171 m high concrete arch dam that will contain a 227 x 10⁶ m³ reservoir.
The construction of hydropower facilities designed mainly for the production of electricity will also lead to further development of the territories, since the reservoir will create favorable conditions for the development of tourism, agriculture and improve transport links.
The projected construction period for the Komarnitsa HPP is five years. A thousand workers will be involved in the work, and after the launch, about a hundred people will work at the hydroelectric power plant - mainly local residents.

In turbomachines the energy transfers between fluid and machine by means of flow forces.
Thermal turbines work with compressible fluids: e.g. gas, wind and steam turbines.
Hydraulic turbines work with incompressible fluids: water turbines.
A characteristic of fans is the pressure ratio, which indicates the ratio of the absolute final pressure to the absolute intake pressure. Fans are different from compressors because of their low pressure ratio of max. 2,5.
In centrifugal pumps the energy is transferred hydrodynamically.In the hydrodynamic transfer of energy the fluid is accelerated by the impeller of the centrifugal pump. Therefore, the impeller of the centrifugal pump has to move with high velocity and thus a high rotational speed.
Axial-flow pumps are also known as propeller pumps. Axial-flow pumps come with fixed blades and with variable blades. The flow passes through the impeller in axial direction. In axial-flow pumps, the pressure is not built up by the effect of centrifugal force but, like the aerodynamic principle, by the propeller blade.
Engineering animations such as cutaway models are ideally suited to representing processes and functions. GUNT uses up-to-date original parts for its cutaway models. Movement and switching functions are maintained.


Jinghong Hydropower Station--Yunnan
- Description: Jinghong Hydropower Station, which began construction in July 2003, will have a combined generating capacity of 1.75 million kw upon completion. It has been built with a dam that is 108 m high and 704
Jinghong Hydropower Station, which began construction in July 2003, will have a combined generating capacity of 1.75 million kw upon completion. It has been built with a dam that is 108 m high and 704.5 m long on the Lancang River, known as the Mekong River once it leaves Chinese territory.
The project is a key part of the country's strategy to develop its vast western region and send electricity from there to the more populated eastern area. Apart from power generation, the project will also bring such benefits as shipping, flood control and tourism development.
With a budget of 12.3 billion yuan (about US$ 1.76 billion), the Jinghong station is the third such facility on the river. It will be capable of generating 7.86 billion kwh of electricity annually when it fully completed next year.
From the Tibetan Plateau, the Lancang runs through Tibet Autonomous Region and Yunnan Province, and flows through Myanmar, Laos, Thailand, Cambodia and Vietnam before emptying into the South China Sea. The river has a length of 2,100 km inside China, and is said to have 25.45 million kw of hydropower potential.
China plans to build 15 power stations on the river with a total installed capacity of 25.2 million kw. At present, the Manwan and Dachaoshan power stations are operational.


Manipur is richly endowed with considerable Hydro Power
Potential. However, barely 108.2 MW has been harnessed in the form of one medium project and micro projects. The Loktak Hydro Electric Project (3x35 MW) commissioned in 1984 is so far the main source of power supply in the State.
