Dubai: Dubai Electricity and Water Authority (DEWA) is notching up steady progress at the Dh1.42 billion Hatta hydroelectric power plant, having touched the 23 per cent project mark. The plant will have a production capacity of 250 megawatts (MW) and a lifespan of 80 years.
“This project supports Dubai Clean Energy Strategy 2050 to provide 75 per cent of Dubai’s total power capacity from clean energy sources,” said Saeed Mohammed Al Tayer, Managing Director and CEO of DEWA. “The project is part of DEWA’s initiative to provide innovative job opportunities for the people of Hatta.”
The tunnelling operations at the location are complete. Each tunnel is 500 metre long. The project has so far recorded more than 3.5 million safe working hours without injuries.
DEWA is implementing two projects in Hatta – the ‘Dubai Summit’ and ‘Hatta Sustainable Waterfalls’. The Dubai Summit includes the construction of a 5.4-kilometre cable car to transport tourists to the summit of Um Al-Nesoor. At 1,300 metres above sea level, it is the highest natural summit in Dubai. The project is expected to be a major tourist attraction in the UAE.
The cable car route passes over the Hatta Dam Lake and the Upper Dam Lake for the hydroelectric power station, as well as through mountains, ending at the summit of Um Al Nesoor.
The ‘Hatta Sustainable Waterfalls’ project will use the slope of the upper dam to create a natural waterfall. A waterway will be built along the parking area below the dam. The water used in the waterfall will be collected at the end of the stream, recycled and pumped back to the top of the dam. The area will be developed to create recreational spaces and restaurants.

Sinicon Comfort Plus drainage system is designed specifically for use in places with increased noise insulation requirements. The drainage system, as shown by the tests, produces at least 4 dB (A) less noise than conventional gray drainage system. The reduction in noise level depends on the water flow in the drainage system - the lower water flow, the lower noise produced.
Pipes and fittings of the Sinikon Comfort Plus drainage system are made of homopolymer of propylene (type 1) PP-H with mineral additives. They differ in their increased wall thickness from standard pipes (for example, the thickness of pipes walls with diameter of 100 mm is 3.4 mm).
The noise level produced by the water flow in the pipes at the level of 2 l/s is only 11 dB (A).

Steady-state empirical and analytical models were developed for symmetric and nonsymmetric vortex resistors. The empirical model for the nonsymmetric (NSVR) configuration (with flow in the high resistance direction) has been developed from experimental data taken on 24 different geometries and at temperatures of 35.0 C to 57.2 C (with MIL-5606A hydraulic oil). The model predictions exhibit a maximum error of 30 percent over the range of the experimental data. Empirical models were also developed for the NSVR configuration with flow in the low resistance direction, and for the SVR configuration. Approximate analytical models have been developed for the symmetric and non-symmetric vortex resistors. Two steady-state analytical models have been developed for the non-symmetric vortex resistor. A one-dimensional model has been developed for the symmetric vortex resistor configuration. Noise measurements made on three typical NSVR geometries (6.35 mm vortex chamber diameter) indicate that the signal-to-noise ratio (for signal levels up to 1,722 kN/sq m pressure drop) of a vortex resistor operating in the laminar flow regime is better than 900.

Double acting, High Tonnage, Lock Nut Hydraulic Cylinders for all movement
New works and galleries in Portugal
Double acting lock nut cylinders
In Portugal, the A4 motorway is expected to expand to improve the viability of the area and the city of Porto. Among the various works, expansion, modification and construction of a new tunnel network was also planned. As part of the first phase of the expansion, both the construction of a new 367 m long tunnel and the renewal of the existing tunnels are planned. The new tunnel, located just north of the original tunnel, will have four separate lanes for traffic traveling from Amarante to Porto; the original tunnels will provide the passage for traffic in the opposite direction.
FPT – Fluid Power Technology collaborated on the project by designing and producing the hydraulic equipment and the double acting lock nut cylinders suitable for the movement of the formwork used for the construction of the tunnels.
Various wagons were used both to waterproof the entire tunnel and to install the reinforcement. The wagon is equipped with hydraulic equipment to facilitate the installation and handling of the formwork, as well as the lowering, levelling and advancement of the entire structure. And finally, for the concrete casting.
The hydraulic unit built is equipped with both a high-pressure line for lifting operations and a low pressure line for the handling and shifting operations. The hydraulic pump has been designed according to the specific needs of the customer, paying particular attention to the aspect of safety and ease of use. The hydraulic cylinders produced are of various types according to the individual operations to be carried out. At the base of the transport wagon double acting lock nut hydraulic cylinders with FPT mechanical locking ring were used to raise and lower the metal structure. The FPT cylinders were used to lift the formwork, the use of double-acting FPT cylinders made it possible to speed down the lowering operations, guaranteeing the prefect control of the movement of the structure.
The tunnel was completely completed in three months, including assembly and disassembly. This is one of the many projects where FPT hydraulic equipment has been built on specific customer needs. Download the product data sheet.

Mambilla hydropower project is a 3.05GW hydroelectric facility being developed on the Dongo River near Baruf, in Kakara Village of Taraba State, Nigeria.
The project is being undertaken by Nigeria’s Federal Ministry of Power, Construction and Housing, with the help of Chinese investments.
Expected to commence operation in 2030, Mambilla will be Nigeria’s biggest power plant, producing approximately 4.7 billion kWh of electricity a year.
The project is estimated to cost $5.8bn and will generate up to 50,000 local jobs during the construction phase.
Mambilla hydropower project development history
Although Mambilla hydroelectric project was originally conceived in 1972, it could advance only after 35 years when China’s Gezhouba Group awarded a contract to develop the project with 2,600MW installed capacity in 2007.
The ground survey for the project was completed in August 2010 and environmental approval was received in December 2011.
The capacity of the project was increased to 3,050MW in 2012. The project was, however, put on hold due to administrative clashes, until it received government approval in 2016.
Nigerian Federal Ministry of Power Works and Housing awarded the project development contract to a consortium of three Chinese companies including the Gezhouba Group, in November 2017.
Mambilla hydropower plant make-up
Mambilla hydroelectric facility will comprise four dams and two underground powerhouses having 12 turbine generator units in total.
The four dams to be constructed on the Dongo River for the Mambilla hydropower project include Nya (formerly known as Gembu), Sumsum, Nghu and Api Weir dams.
Nya and Sumsum will be 100m and 35m-tall roller compacted concrete (RCC) dams with crest length of 515m and 460m, respectively.
Nghu will be a 95m-high rockfill dam with a crest length of 650m, while Api Weir will be a small regulatory dam to raise the water level of the river.
Nya and Sumsum dams will be connected through a 16km-long, 6m-diameter tunnel, whereas Sumsum and Nghu dams will be connected by a 1.5km-long and 10m-wide canal.
The headrace canal for the plant will be 3.1km-long and 15m-wide.
Each underground power house of the plant will measure 175mx27mx38m and house six 250MW Pellton turbine units operating at a total dynamic head of 1,007m.The diameter of the power shafts connecting each turbine will range between 5.25m and 8.40m.
Two 6km-long tailrace tunnels for the plant will be of 8m diameter each, while the tailrace canal will be 3km-long and 25m-wide.
Financing for Mambilla hydropower project
Chinese Export Import (Exim) Bank is funding 85% of the estimated $5.8bn project cost, while the remaining 15% funding will come from the Federal Government of Nigeria.
The power generated by the Mambilla hydroelectric facility will be transmitted to the national grid by four 500kV DC transmission lines connecting Makrudi, and one 330kV DC transmission line connecting Jalingo.
The combined length of the transmission lines will be 700km.
Contractors involved with Mambilla hydroelectric project
The engineering, procurement and construction (EPC) contract for the Mambilla Hydropower project was awarded to a joint venture between China Gezhouba Group (CGGC), Sinohydro and CGCOC (formerly CGC Overseas Construction), in November 2017.
The EPC contract is led by China Gezhouba Group, which is a subsidiary of the state-owned China Civil Engineering Construction Corporation (CCECC).
Studio Pietrangeli, an engineering company based in Italy provided the design for the hydropower project.
London-based Bennie&Partners along with Diyam Consultants were earlier engaged to carry out the feasibility study for the project which was later reworked by Lahmeyer International.
Messrs Maps Geosystems completed the detailed aerial mapping for the project in 2008.

Plans to improve the reliability of Gloucester’s water supply network are set to take a significant step forward, with MidCoast Council expected to appoint a contractor to undertake the construction phase of the project at the 24 March Council meeting.
The project will ensure consistent water quality and pressure is supplied throughout the network and replace infrastructure that has deteriorated over time.
“The construction of a seven megalitre reservoir and a second small elevated reservoir will largely eliminate the current reliance on pressure booster pump stations. These boosters cause continuous pressure fluctuations in town and fail completely during power outages,” said Council’s Director of Infrastructure and Engineering Services, Rob Scott.
The new reservoirs will be built at Council’s existing Cemetery Road site and will be connected to the water treatment plant via a pipeline that will be constructed from the showground. A gravity water main will also be constructed from the Cemetery Road site to the industrial area to address ongoing issues with water pressure in that part of town. Several other mains will also be upgraded throughout the network, allowing for old infrastructure to be decommissioned.
Mr Scott said the additional storage capacity provided by the new reservoirs would also prove beneficial during wet weather events, as they would reduce the need to draw from the Barrington River during times of high turbidity.
“This will greatly reduce the risk to the drinking water system and make it a lot easier for our operators to guarantee the treated water quality.”
It is anticipated the project will take around 12 months, with construction expected to begin in June. An accurate timeframe will be provided to the community once a contractor has been appointed.
Council is also committed to improving Gloucester’s water security in the long term, however Mr Scott said this would be an expensive undertaking that would require considerable investigation and extensive community consultation.
“In the meantime, upgrading Gloucester’s existing infrastructure will go a long way towards improving the reliability of the town’s water supply.”

Bypass Channel Construction
Photo: Jersey Village Bypass Channel
A bypass channel diverts excess stormwater "around" an area with restricted right-of-way or an area with sensitive environmental values. Bypass channel construction involves building a new channel that is attached to an existing channel and, as mentioned, conveying the excess stormwater runoff around its original path. Bypass channels usually "short circuit" the meander or curve of a bayou and are usually constructed in conjunction with downstream channel modifications or a detention basin.

Check valve belongs to automatic valve category, which is mainly used in one-way flow pipe of medium. Only the medium is allowed to flow in one direction to prevent accidents. Usually, the fluid opens the valve disc under pressure and flows from the inlet side to the outlet side.
1. disc broken;
2. media backflow. The reason for the valve breaking is that the dielectric pressure before and after the check valve is in a state of close balance and mutual "pull saw". The valve plate often beats with the valve seat, and the valve plate made of some brittle materials (such as cast iron, brass, etc.) is broken.
The preventive method is to use the valve as a ductile material check valve.
Reason for media backflow
1. Sealing surface damaged;
2.Repair the sealing surface and remove impurities to prevent backflow.

The water level sensor can be divided into contact type water level sensor and contactless liquid sensor according to the measurement method. Water level sensors are often used in water treatment, metallurgy, petroleum, chemical industry and other industries. Here are two water level sensors with different measurement methods: Contact and contactless water level sensors.
The contact water level sensors, as level indicator transmitter types, include the capacitive type, floating ball type, floater type and pressure type. In the process of water level measurement, detection sensors are in direct contact with the measured medium. In some applications, the detection sensor will produce reactants, which leads to the sensor's abnormal working. Therefore, when choosing the sensor, you need to understand the characteristics of the medium to be measured.
Contactless water level sensors mainly include radioactive isotope type, ultrasonic type, radar type, external paste type, magnetostrictive level sensor. For radioactive isotope type water level sensor, it is not suitable for occasions where large range water level measurement is needed because of its small measuring range. The ultrasonic water level sensor, made by ultrasonic level sensor manufacturers, has a wide range, which can be used to conduct large range measurements. What's more, contactless measurement is also achieved, which is not affected by the medium. The disadvantage is that the application of ultrasonic water level sensors is restricted by medium temperature, ambient temperature, the fluctuation degree of measured water level and many other external environmental factors. These restrictive factors will seriously affect the measurement accuracy of ultrasonic water level sensors. The medium characteristics have a certain influence on the measurement range of radar water level sensors. The liquid with a small dielectric constant has a great influence on the measurement distance of the radar water level meter, which reduces its measurement range. The liquid with a large dielectric constant has little effect on the measuring distance of the radar water level meter, and the measuring range is enlarged. The water level sensor of the external paste type is suitable for the measurement of sealed containers and inflammable and explosive dangerous media. The probe can be directly adsorbed on the bottom of the container and measurement can be finished by using the principle of sonar ranging without trepanning the container and stopping to measure.
Therefore, different liquid level sensors have different application occasions. According to the needs of field measurement, we decide to choose the contact type or contactless liquid sensor, and then see which measurement principle is more suitable for current liquid level measurement.

A foot valve is a check valve, which is mounted at the bottom of a suction line. If the pump is switched off, the foot valve prevents the emptying of the suction line. This keeps the pump primed and ready for use. In addition, a foot valve is usually equipped with a filter, in order to prevent contaminants from reaching the pump or the foot valve itself. We have foot valves made of several materials in our collection.

Earlswood Lakes - major repairs
From April 2021 we're carrying out some major repairs to Earlswood Lakes. As this is likely to have some impact on residents and visitors we wanted to share our plans and explain why this work is important.
The project is expected to last around six months and will involve:
- Temporarily lowering the water levels within the Engine and Windmill Pools. This will maintain the safety of the dam until works are complete and allow our construction team easy and safe access to the reservoir dam wall and embankment.
- Raising the core of the reservoir main dam along Valley Road. This will help improve the dam resilience during flood events.
- Installing drainage and a collector drain within the embankment of the main reservoir dams adjacent to Valley Road. This will help drain rainwater away from the embankment.
- At Windmill Pool, the footpath along the top of the River Blythe embankment, will be raised to prevent the reservoir from topping over along this length.
- Erosion damage to the wall of the dams and to the toe of the dam in the River Blythe will be repaired at various areas in both Engine and Windmill Pools.
- To improve waterflow along the River Blythe the culvert will be fitted with a trash screen to prevent it becoming blocked with litter and debris
- To allow colleagues easy access to the reservoir for essential reservoir safety maintenance purposes, new access areas will be created at the base of Windmill Pool and at Engine Pool dams as well as near the River Blythe channel outlet on Windmill Pool dam.
- The channel from Terrys Pool to Engine Pool car park will be desilted and the bank between channel and reservoir improved.
Road and footpath closures
- From the 29 March, and throughout the works, Wood Lane car park will be closed.
- From the 13 April - the Engine Pool footpath will be closed from the northern section of Engine Pool to the path between Terrys and Engine Pool. The access from Mason Lane will also be closed
- From 19 April the Causeway roads (including the section of Malt House Lane that separates Engine and Windmill pools) will be closed to vehicular and pedestrian traffic. The eastern path at Windmill Pool will also be closed from the pathway between Engine & Windmill and the main dam crest.
All local businesses will remain open and trading throughout these works.
The work is due to be completed by November 2021.

Sanguem: The Selaulim dam at Sanguem began to overflow from the duckbill spillway at its crest on Friday morning when the water level at the dam reached 41.15 metres.
With heavy rains in the taluka over the last few days, the reservoir got filled to the brim five days earlier as compared to last year, informed Assistant Engineer Jason Menezes, attached to the Water Resource Department office in Sanguem.
Menezes further informed that the total rainfall in the area as of Friday morning was 1599 mm, which is 314 mm more compared to the same day last year, resulting in water overflowing from the duckbill spillway at its crest five days earlier.
The total water storage capacity of the dam is 234 million cubic metres, informed the official.
Menezes also informed that while entry to people at the dam site is banned for security reasons, visitors are permitted to visit the Botanical Garden on the other side of the dam area.
Ever since the construction of the Selaulim dam, people would flock to experience the enchanting beauty of the overflowing waters at the dam.
However, entry to the dam site has been banned for since the last two years and there has been considerable resentment among the public.

© 2017 Hydrogen Energy Publications LLCDraft tube is the part of Francis turbines which is used to both discharge water and recover kinetic energy at the exit of the runner. A design optimization study of an elbow type draft tube based on the combined use of Computational Fluid Dynamics (CFD), design of experiments, surrogate models and multi-objective optimization is presented in this study. The geometric variables that specify the shape of the draft tube are chosen as input variables for surrogate models and the pressure recovery factor and the head loss are selected as output responses. It is determined that, pressure recovery factor, which is the main performance parameter, can be increased by 4.3%, and head loss can be reduced by %20 compared to the initial CFD aided design. Pressure recovery factor, is represented with a second order polynomial regression model in terms of the geometrical parameters based on the optimization results. The verification of the model is also provided by comparison with CFD results for different draft tubes other than that are used in the development of the model. The model is verified using 30 different design points and it can predict the pressure recovery factor with an error of less than 8%. This model allows the fast and correct design and optimization of elbow type draft tubes, without the need for further CFD simulations.

In order to determine the layout method of storage facilities up to standard, three drainage systems with the different drainage characteristics are selected, and the general rules of the layout of storage facilities are studied. The calculation results of the model show that the layout of storage facilities up to standard mainly depends on the location of the waterlogging in the drainage system. The layout of storage facilities at the upstream of the waterlogging location can obtain a good effect of waterlogging reduction. According to the research results, the evaluation index of the storage facility layout and the corresponding layout planning and design method of storage facilities based on the potential of waterlogging reduction are put forward, which provides a reference for the planning, layout and design of storage facilities up to standard.


Why it's important
Antero Dam is fully operational, but it’s old. The dam has been in service for more than 100 years, and this rehab project helps ensure the dam can operate for another 100 years. That meant a big, but necessary, project to bring the dam more in line with current standards of engineering and safety.
How it impacts recreation
Anglers and campers can rejoice, because the reservoir, popular recreation spot, reopened for camping and modified fishing on June 5. Recreationists should still expect to see construction activity on the south side of the reservoir as Denver Water works on the final phase of the dam rehabilitation project.

LAHORE: The 720 MW Karot Hydro Power Project is being connected to national grid through a 500kV double circuit transmission line existing evacuation arrangements of Neelum Jhelum HPP as per schedule, a statement said on Wednesday.
The National Transmission and Despatch Company (NTDC) has achieved 90 percent progress on the transmission line construction. The remaining work will be completed upon receiving go-ahead from Karot hydro power project authorities as the work is to be done inside Karot premises.
As part of China Pakistan Economic Corridor (CPEC), the 720-MW Karot hydro power project is being constructed under independent power producer (IPP) mode by China’s Three Gorges Corporation and is located partially in Karot Village of Kahuta, Punjab. The project, costing estimated $1.72 billion was originally planned to be commissioned in December, 2021, however, there is a slight delay in the project execution due to restrictions imposed by the Karot plant authorities as a result of prolonged lockdowns in the wake of Covid-19 pandemic.
The Karot hydro power project will be connected to National Grid through a 3km 500kV Double Circuit Transmission Line through in/out arrangement from existing Neelum Jhelum Transmission Line. Contract price for 500 kV transmission line for interconnection to Karot HPP is Rs78.643 million
The power will be evacuated through NTDC system and will be delivered to load centers of Punjab province. The clean energy obtained from these hydropower projects will be useful to drive industries etc. and would prove beneficial for the national economy in the large.
According to project details, the financial close of Karot Hydropower Project was achieved in March 2017. The Karot hydropower project is a run-of-river project being built on the Jhelum river. It is being developed by Karot Power Company (KPCL), a special purpose vehicle in which China Three Gorges South Asia Investment (CSAIL) holds a majority share.
The project is being developed in the private sector under the Power Policy 2002 on a Build-Own-Operate Transfer (BOOT) basis with an expected concession period of approximately 35 years, which includes the construction period of 5 years and the operation period of 30 years.
CSAIL was established by China Three Gorges Investments, the overseas intermediary of China’s state-owned China Three Gorges Corporation (CTGC). CTGC was founded to build the Three Gorges Project, which is the world’s biggest hydroelectric power plant with a 22.5GW capacity.
The Karot HPP is the fourth of five cascade hydropower stations planned on the Jhelum River. It will generate 3,174GWh (net) of energy a year, which will be sold to NTDC under a 30-year power purchase agreement. The generated power will be sufficient to power approximately seven million households.
The reservoir is expected to stretch approximately 27 kilometer upstream of the dam and feature a capacity of 152 million cubic metres at full supply level (FSL), which will be 461m above sea level. The surface powerhouse, consisting of four turbines, will be situated approximately 650m downstream of the dam crest and 300m upstream of the Karot Bridge.
