LHDA advertises Tender for construction of Polihali Water Transfer Tunnel in Lesotho
The Lesotho Highlands Development Authority (LHDA) has advertised a tender for construction of the 38 kilometre Polihali Water Transfer Tunnel.
The construction of the Polihali Transfer Tunnel is part of the Lesotho Highlands Water Project (LHWP) Phase 2.
The 38 kilometre long Tunnel will have a nominal bore of five metres, and will be excavated using both tunnel boring and drill and blast methods. The Polihali Transfer Tunnel works also includes the intake works and gate shaft at the Polihali reservoir; outlet works and gate shaft at the existing Katse reservoir, with underwater connection to the lake; access adits to the waterway and associated construction infrastructure.
The Lesotho Highlands Water Project (LHWP) delivers water to the Gauteng region of South Africa and utilises the water delivery system to generate electricity for Lesotho. In Phase 2 of the LHWP, the Polihali Dam will create a reservoir on the Senqu and Khubelu rivers with an estimated surface area of 5053 hectares and a full supply storage capacity of 2325 million m3.
The flow from the Polihali reservoir through the transfer tunnel will increase the volume of water in the Katse Dam and the current water supply rate of 780 million m3 per year to the Gauteng region of South Africa will incrementally increase to 1270 million m3 per year. At the same time, it will increase the quantity of electricity generated at the Muela hydropower plant which is a further step in the process of securing an independent power supply to meet Lesotho’s domestic needs.
“Our objective is to attract firms with experience in the construction of major underground works under complex geological and geotechnical conditions, diverse environmental conditions, in remote areas and at high altitude,” said the Chief Executive Officer of LHDA, Tente Tente.
“Equally important is to attract firms that have impeccable records in delivering projects of this magnitude within budget and the set timeframes.”
The closing date for submission of tenders is 30 August 2021. Interested construction firms can obtain further information on the requirements and conditions of the tender from the LHDA website.
The contract for the design and construction supervision of the Polihali Transfer Tunnel and its secondary structures was awarded to the Metsi a Senqu-Khubelu Consultants (MSKC) Joint Venture. The MSKC Joint Venture comprises Lesotho-based FM Associates (Pty) Ltd, and South African firms Zutari (Pty) Ltd, Hatch Africa (Pty) Ltd, Knight Piesold (Pty) Ltd and SMEC South Africa (Pty) Ltd.
Timely construction of the dam and transfer tunnel is critical to meeting the water delivery deadline of the project. According to the current master programme, water delivery is scheduled for September 2027.

Control and Controllability of Electrohydraulic Valvetrain in High and Medium Speed Diesels 2002-01-2175
An electrohydraulic valvetrain for experimental engine, having power density twice the level of current production engines, has been developed by the Institute of Hydraulics and Automation of Tampere University of Technology. Valvetrain offers significant benefits in comparison to traditional cam actuated valvetrain to control of the engine and also to general engine design.
Applying an electrohydraulic subsystem for valve actuation into the engine, having speed range up to 1600 rpm and combustion pressure range up to 400 bar, sets speed and controllability requirements of the electrohydraulic system to very unusual level. Hydraulic system peak power of approx. 100 kW and the nominal actuation time of 6 ms make hydraulic component and both hydraulic and control system design very different from traditional hydraulic systems. Delays caused by single hydraulic components and hydraulic volumes as well as dynamics of them have much more significant effects on the performance of the complete system than in traditional hydraulic systems. Speed of the system also makes it impossible to utilize control strategies usually used in electrohydraulic systems but a completely new approach is needed.
The paper will give an indepth introduction to valvetrain and its control system design. Simulation models used in design, hardware-in-the-loop models for testing the control system and combined Amesim hydraulics model / Simulink control system model are discussed. Also the final valvetrain construction and dSpace control system are introduced.

New pump stations planned for Minnesota pipeline
Minnesota Pipe Line Co. plans to build new pump stations in Minnesota along its newest pipeline, which is part of a system delivering crude oil to Minnesota refineries.
The project will place new stations in the rural areas of Hubbard, Wadena, Morrison, Meeker, McLeod and Scott counties.
The new pump stations will use available capacity to ensure the reliability of the company’s pipeline system, the company said in a news release.
The system is the primary pipeline system supplying refineries that produce much of the transportation fuels used in Minnesota and the Upper Midwest.
The addition of the six pump stations and upgrades at existing stations will allow the pipeline, called Line 4, to operate at its original design capacity of 350,000 barrels of crude oil per day when needed. Line 4 currently transports about 165,000 barrels per day. No new pipeline will be installed in the project.

PIERRE, S.D.(KCCR)- While the level of the Oahe and other reservoirs on the Missouri River main stem system are low, the system is roughly only half-empty compared to the record all-time minimum low in 2007. John Remus, Chief of the Missouri River Water Management Division of the U-S Army Corps of Engineers says drought conditions would need to continue to get to 2007 lows.
The historic low for system storage in 2007 was 33-point-nine million acre feet. Current system storage is at 51-point-three million acre feet or 17-point-four million acre feet above the 2007 all-time low. Lake Oahe’s 2007 low elevation level was 1570-point-three. It currently sits at 1598-point-two or 28 feet above the all-time 2007 low mark.

The Kihansi hydro power project in Tanzania, one of the largest electricity projects in the country, has been inaugurated by Tanzania’s President Benjamin Mkapa. But while the 180MW Kinhansi project takes off, power rationing looks imminent as water levels have dropped considerably at the Mtera and Nyumba ya Mungu dams in southern and northern Tanzania.
Ethiopia is facing similar problems. The Ethiopian Electric Power Corporation (EEPCO), the only power distributor in Ethiopia, has instituted a power rationing schedule which includes a total 16-hour blackout every fourth day. This latest power rationing measure has replaced an earlier one under which there was a blackout for a similar duration every three days. The improved rationing schedule is possible due to an increase in water at the dams of the Koka and Melka Wakena hydro plants, the two biggest suppliers of electricity in Ethiopia.
Finally, Malawi is working on completion of the US$130M Kapichira hydroelectric power plant which, officials say, will improve the power generation capacity of the Electricity Supply Corporation (ESC) of Malawi.

Two 32MW units have already been commissioned and another 64MW (2x32MW units) will be added to the national grid when the project is completed in 2003.
ESC’s project manager Lameck Mchembe said although the project will ensure that electricity generation will improve, the corporation will also go ahead with plans to obtain power from neighbouring Mozambique’s Cahora Bassa dam.

Solar water pumps are specially designed to utilize DC electric power from photovoltaic panels. They must work during low light conditions at reduced power, without stalling or overheating.
Low volume pumps use positive displacement (volumetric) mechanisms which seal water in cavities and force it upward. Lift capacity is maintained even while pumping slowly. These mechanisms include diaphragm, vane and piston pumps. These differ from a conventional centrifugal pump that needs to spin fast to work efficiently. Centrifugal pumps are used where higher volumes are required.

The PS2 series piston dosing pump also offers multiple combinations of pump heads and motor power that enables it to adapt to a large number of applications. The PS2 achieves flow rates of between 10.5 – 340 g/h with a pressure up to 80 psi.
PS2 Series is also flexible, being able to alter its hydraulic characteristics thanks to a bigger size of piston and longer stroke length, which therefore alters the flow rate and power.
The PS2 pumps have a spring-loaded mechanism in an aluminium housing, and each model can be adjusted to between 0-100% of the total flow rate. This can be done manually or automatically by using the AKTUA actuator which operates with a 4-20 mA signal.

In a world-first, two disused goldmine pits in Queensland are being transformed into an energy storage facility, with its main access tunnel currently being dug and expected to be complete in early 2022.
The pits sit underground at two different heights, making it ideal as a pumped hydro project. Genex Power has undertaken extensive works throughout December and January to establish the tunnel at the Kidston Pumped Hydro Storage Project (K2-Hydro) in Far North Queensland.
CEO of Genex, James Harding, revealed that the engineering, procurement and construction (EPC) joint venture of McConnell Dowell and John Holland has commenced the subterranean excavation while Entura has signed on as the engineering consultant.
McConnell Dowell said the two mine pits would be converted into reservoirs, which will involve “the construction of significant underground infrastructure including a large powerhouse cavern and waterway shafts and tunnels”.
The cavern will be 250 metres below ground level and home to two 125 MW hydro reversible pump turbines that will generate electricity and pump water. Ultimately, 250 MW/2000MWh of storage capacity will be available.
The main access tunnel, when complete, will be six metres wide as well as high, with a length of around 1.5 kilometres. John Holland revealed the project will create 800 jobs, calling it a ‘game-changer’ for the clean energy industry with its new approach to large-scale energy storage.
The K2-Hydro project is expected to be complete in Q4 in 2024 when it will become the fourth operating hydro project in Australia. It will join the NSW-based Tumut 3 power station, part of the Snowy Hydro scheme, and Shoalhaven scheme, and the Wivenhoe Power Station in Queensland. A fifth project is currently being developed as part of the Snowy 2.0 project which will be the largest once it is operational.

Importantly, Uganda has several new projects in the pipeline. One such project is the Isimba Hydropower Plant, which is currently under construction on the Victoria Nile. Noteworthy, Isimba Plant is 40 kilometers downstream from the Bujagali plant. Additionally, the Isimba plant is expected to have an installed capacity of 183 MW.
Another major project in the works is the Karuma Hydropower Plant, which is being constructed on the White Nile. Moreover, Karuma Hydropower Plant is 110 kilometers downstream from the town of Karuma. The Karuma plant will have an installed capacity of 600 MW, making it the largest hydroelectric power plant in Uganda.
Uganda’s Renewable Power Capacity on River Nile
Uganda has significantly been harnessing renewable power from the river Nile over the years. Reportedly, one of the most significant hydroelectric projects in Uganda is the Bujagali Hydropower Plant. Located 8 kilometers north of the town of Jinja, the Bujagali plant has an installed capacity of 250 megawatts (MW). The project was developed as a public-private partnership between the government of Uganda, the Aga Khan Fund for Economic Development. Noteworthy, the Bujagali plant has significantly increased Uganda’s power generation capacity. Furthermore, it has helped to reduce the country’s reliance on expensive and polluting fossil fuels.
In addition to Bujagali plant, Uganda has several other hydroelectric power plants in operation, including the Nalubaale and Kiira plants. The Nalubaale plant, formerly known as Owen Falls Dam, was commissioned in 1954 and has installed capacity of 180 MW. The Kiira plant, which was commissioned in 2000, has an installed capacity of 200 MW. Together, these three plants account for the majority of Uganda’s hydroelectric power generation.

Tampa Bay Water’s Cypress Creek Wellfield Surface Water Improvements project was approved for $432,500 in state funding as part of the 2014 state budget. The state funding represents 50 percent of the construction costs to make drainage modifications at the Cypress Creek Wellfield.
The project builds on earlier efforts to successfully re-route excess surface water on the wellfield property to rehydrate wetlands and enhance the shallow aquifer. Five wetlands on the property will benefit from the newly planned enhancements to the surface water management system. Additionally, the project has the potential to alleviate some nuisance flooding in adjacent subdivisions.
The project started in 2004 with a feasibility study that evaluated potential drainage modifications and determined the project was viable. The first phase of the project was completed in 2007 and has proven successful.
This phase of the project builds on the previous efforts. The total project cost is approximately $1,000,000 for design, permitting and construction. Construction is scheduled to begin in spring 2015.

- Q:Can the slow stop disc check valve close quickly?
- At this point, the valve will automatically close under the influence of the spring and the medium return. However, as the piston rod is in an extended position, the valve can not be closed all the way, and there is about 20% of the area left to make the medium pass, so as to eliminate the water hammer. The disc is divided into two parts by the piston, which is fast, slow and slow. It can not only prevent the motor from reversing, but also eliminate the mute effect.
- Q:What are the differences between different check valves applications?
- The application performance of the acoustic check valve only allows the medium to flow in one direction, and prevents flow in the direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Not suitable for medium containing solid particles and viscosity. The design of the check valve takes full account of the requirements of the use of the environment, and uses the inclined plate structure to achieve no vibration, no noise, stable operation, and ensure the quiet environment of the hotel and the residential environment, and has the effect of energy saving.

- Q:What is the purpose of installing a check valve in the air pipe before the fan?
- Check valveRefers to rely on the flow of the media itself and automatically open and close the valve, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q:How can the check valve be distinguished from the cut-off valve?
- 1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed. 7, Y%, s) C, N, L., Q3, U6, J&, E9, R2., the cut-off valve can be used to regulate flow, can be closed, can be closed.
- Q:What type of check valve should be installed before the suction pump?
- Swing, turn, or automatic (note, anyway) can be.
- Q:What happens when the check valve is broken?
- Check valve is broken, there will be back water, down pressure, serious will produce pump reversal, burning motor
- Q:How do I install the pump outlet check valve?
- Because the check valve is easy to be damaged, therefore, the check valve shall be installed near the pump outlet, and a shut-off valve (usually ball valve or gate valve) is arranged on the top of the check valve, so that it is easy to overhaul. In order to facilitate the check valve before disassembly pressure relief, the valve itself is not equipped with a net valve, should be installed between the check valve and the shut-off valve with pressure relief valve.
- Q:Ball shaped sewage check valve pictures and working principle of the structure.
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q:Does the Vatti range hood e601a2z have check valves?
- The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve:1. lift check valve is divided into two types of vertical and horizontal.2. swing check valve is divided into single, double flap and multi flap type of three.3. butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.
