NiBRAS is a decision support system that intends to promote societal applications of satellite missions in water management practices.
The NiBRAS system is designed to provide users with three main outputs:
1) Real-time monitoring of reservoir operation using a reservoir modeling approach;
2) Forecasting of reservoir outflow and storage change using global numerical weather prediction (NWP) model-based forecasts of the weather.
3) Assessment of reservoir operation under various scenarios (e.g., LULC, climate change, GW recharge, and transboundary dams).


A dual level design methodology for designing detention basins has been developed in an effort to standardize detention basin design and expedite the design/review process. The methodology utilizes a dual level design approach. The first level involves use of nomographs to determine the dischage and volumetric requirements of a detention facility to meet the drainage specifications set forth by a municipality. The second level of the methodology involves using the values of design discharge and maximum storage obtained from the nomographs along with a computer program to design the outlet works of the associated structure. The developed methodology provides both a uniform and a streamlined process for the design of stormwater detention basins for small urban watersheds where more comprehensive methodologies may not be cost effective or readily available.

To evaluate the protection effect of the Three Gorges Dam Project (TGP) on the flood in the middle region of the Changjiang River basin, we applied the integrated watershed hydrological model using gauged daily precipitation data of 1998 when the second largest flood occurred in the basin in the last century. From the results simulated by applying the discharge volume controlled by each upper limitation value from 40, 000 m3/s to 60, 000 m3/s, we could not find the clear effect on the reduction of the water level during flood period not only in the Dongting Lake but also in the Changjiang mainstream in the cases that the upper limitation discharge value were over 50, 000 m3/s. In the case that the upper limitation value was 40, 000m3/s, although the flood protection effect was clearly exerted in both the mainstream and the lake, the simulated storage volume of TGP remarkably exceeded the total flood control volume (221.5×108 m3) at the peak of inflow to TGP. These results suggested that TGP flood control ability does not efficiently work for the decrease of flood damage in the middle region of the Changjiang basin in case of the occurrence of 1998 type flood phenomena.

The impounded reservoir, also formed with the Edgar Dam and the Serpentine Dam, is called Lake Pedder which flooded Lake Edgar, a naturally forming fault scarp pond. The dam was constructed in 1973 by the Hydro Electric Corporation (TAS) as part of the Gordon River Power Development Scheme for the purpose of generating hydro-electric power via the conventional Gordon Power Station. Water from Lake Pedder is diverted to Lake Gordon (formed by the Gordon Dam) via the McPartlan Pass Canal.
Location and features
The Scotts Peak Dam, together with the Edgar Dam and the Serpentine Dam, are three major dams that form the headwaters for the Gordon River Power Development Scheme. The dam is located near Lake Pedder's most easterly point in the upper reaches of the Huon River where the river descends from the Marsden Range and descends into what is now known as the Huon Basin. Also at the southern end of the Lake Pedder, the Scotts Peak Dam impounds the upper reaches of the Huon River. At the northwestern end of the lake is impounded by the Serpentine Dam across the Serpentine River. The water in Lake Pedder provides around 40% of the water used in the Gordon Power Station. The water flows to Lake Gordon via McPartlan Canal. Water from Lake Gordon then exits through the Gordon Dam.
Built on a foundation of rock and soil, the Scotts Peak Dam wall was constructed with 584 thousand cubic metres (20.6×106 cu ft) of rockfill and faced with asphalt. The dam wall is 43 metres (141 ft) high and 1,067 metres (3,501 ft) long. At 100% capacity the dam wall holds back 2,937,930 megalitres (103,752×106 cu ft) of water. The surface area of Lake Pedder is 241,330 hectares (596,300 acres) and the catchment area is 734 square kilometres (283 sq mi). The dam wall does not have a spillway.
This non-hydroelectric dam helps retain water in the new impoundment, which then flows to Lake Gordon via the McPartlans Pass Canal at Engineers Australia.. In 2001 the dam was recorded as an Historic Engineering Marker along with twenty-four other dams by
In the 2008 edition of Ticklebelly Tales engineers associated with the dam acknowledge that there were issues leaks as soon as it was built. Evidence of deformation is still current in the 2010s.

Water System Improvements
LOCATION: Corryton, Tennessee
- Steve Bostic
CONSTRUCTION COST: $2.5 Million
- 2 Storage Reservoirs
- Remote Telemetry Unit
- USDA-Rural Development Program
The overall improvements project for the North East Knox Utility District consisted of 2 new 1 million gallon water storage reservoirs, a new booster station, and the construction and installation of new water transmission line. One of the new storage reservoirs was constructed on Babelay Road, and the other reservoir was built on Terry Drive both were pre-stressed concrete. Additional tasks associated with the reservoirs included site grading, slope stabilization, and altitude valve pits and appurtenances. The reservoir on Babelay Road also required a concrete retaining wall, as well as 2,100 linear feet of 16-inch ductile iron pipe.
The new water booster station involved two 1,000 gpm vertical turbine pumps, installation of a new remote telemetry unit (RTU) control system including telemetry connection to a new water storage tank, and SCADA equipment and programming. LDA was also tasked with installing 6,200 linear feet of new 12-inch ductile iron water transmission line and appurtenances between the new booster station and new storage reservoir. The majority of the new line was installed outside of the right-of-way on private easements. A tie-in at the booster station was added, along with a 16-inch stub-out for connection to the new storage reservoir.
LDA provided design, services during construction, surveys and document preparation services, and property acquisitions.Back to Projects


Rifa Compensation Reservoir
As part of a capacity enlargement programme for a whole chain of power plants, the storage volume of the Rifa reservoir needed to be increased from 670,000 m3 to 1,100,000m3.
In order to increase the storage volume of the reservoir so dramatically, the existing earth dam needed to be lifted by five metres and the asphalt slopes had to be extended by twelve metres. All WALO’s work had to be undertaken during the normal operation of the power plant, which was achieved by reducing the water level in the reservoir and then working on the slopes above it.
To ensure that the connection between the existing liner and the new extension lining was impermeable and durable, the existing dense asphalt course was milled along its upper edge to form a strong key between the linings. The drainage gravel, the Asphaltic Binder Layer (ABL) and the Dense Asphaltic Concrete (DAC) were installed by paver and the joint between them and the existing asphaltic lining was formed in a conventional manner, ensuring a homogeneous lining system. Further stages of the modernisation included the construction of additional inlet/outlet structures and a further, second extension was created by building a wave-breaker around the crest.


The Bureau of Reclamation will spend 18 months project in late 2013 upgrading a ’70s-era relay system that serves high voltage power lines connected to the Grand Coulee Dam.
The relay system protects seven transmission lines that run from a hydroelectric power plant to the 500-kV and 230-kV switchyards. From those switchyards, the dam’s energy is connected to the regional power grid.
The Bonneville Power Administration (BPA) will fund the $4 million project, which will also include installing several miles of fiber optic cable for relay communications between the switchyards and power plants.
The upgrades are scheduled to be completed by April 2014.
Other preliminary projects include the replacement of oil-filled transmission cables within the dam itself with overhead 500-kV transmission lines.
Power facilities at Grand Coulee Dam include 33 generators in three power plants, a pumping plant and three switchyards. Total rated generating capacity of the dam is 6,809 MW, making it one of the largest hydropower producers in North America, according to BPA.


ISLAMABAD, (Pakistan Point News - APP -22nd Augst,2016) : As many as 67 per cent work has been completed on the Tarbela 4th Extension Power Project so far and its unit would start supplying power generation by August 2017. Official sources told APP here Monday said that the up- gradation of the Switchyard was scheduled to be completed in May 2017, which would enable WAPDA to disperse electricity from Tarbela Hydel Power Station to the National Grid after completion of Tarbela 4th Extension Hydropower Project.
They said the project would cost $ 920 million and additional 1410 MW cheaper hydel electricity would be generated. Earlier the project was scheduled to be completed in 2018, but on the directive of the prime minister, work has been expedited on the project and now it would be ready by next year. The World Bank was providing $ 840 million for the project while Water and Power Development Authority arranged the remaining $ 80 million.
Three units of 370 MW each would be installed at the power house which would enhance the total electricity generation to 4888 MW from the existing 3478 MW. Dilating upon the benefits of the project, they said that the project having three units of 370MW each would produce 3,840GWh of cheap hydropower at a time when electricity needs would be at peak in hot and humid weather. Annual benefits of the project have been estimated at around Rs30.7 billion. The project will pay back its cost in just three years.

The Tanzanian presidency is hosting on Wednesday the signing ceremony of the Stiegler’s Gorge dam project in Tanzania between Tanzanian President John Magufuli and Egyptian Prime Minister Mostafa Madbouly on behalf of President Abdel Fattah al-Sisi.
The owner of the project is the Tanzanian Ministry of Energy, while Arab Contractors and Elsewedy Electric are constructing the project.
The power station would be located across the Rufiji River in the Stiegler’s Gorge of the Selous Game Reserve in the Morogoro region, which lies 220 kilometers southwest of Dar es Salaam, the commercial capital and largest city of Tanzania.
The project aims at generating electricity of 2,115 MW to provide energy needs in Tanzania, as well as controlling water levels during flood periods and thus providing the water needs of the Tanzanian state.
Construction on the project is scheduled to take 36 months to complete, Tanzanian “Daily News” reported last month.
The 134-meter dam will have the storage capacity of 34 million cubic meters of water. The reservoir will be 100-kilometer long and 1,350 square kilometers in area, while the earth embankment will be 3.7 million cubic meters.
The powerhouse will be above-ground and consist of nine vertical Francis turbines with capacity ranging from 200 MW to 300 MW each, and power generators with a capacity of 1,200 MW each.
Power transformers of 235-353 MVA each and having combined capacity of 2,470 MVA will be installed. The plant will also include a 400 kV switch yard.
Additional infrastructure will include electric switch gears, protection system and fire detection system, along with auxiliary power supply, DC systems, cooling and sewage systems.
Construction of the 10-kilometer internal roads, 15-kilometer long residential roads, 350 permanent houses and 3,000 secondary houses is also part of the project.
The construction work in the dam will last three years, starting in January and will conclude in 2022. The project will cost $2.9 billion and employ about 5,000 people.

Pakistan to begin construction of Sukhi Kenari hydel project6 March 2011
The government of Pakistan will shortly begin construction of the 840MW Sukhi Kenari hydel project in the Khyber Pakhtunkhwa province of Pakistan.
The run-of-river hydro power project will be built on the Kunhar River, a tributary of River Jehlum, in Mansehra. The project will include the construction of a 21.4km headrace tunnel. The construction cost of Sukhi Kenari hydel project is estimated at $1.14 billion The Khyber Pakhtunkhwa government has approved the environmental impact assessment report of the project while submission of performance guarantee by the sponsors is under process and is expected to be completed shortly. Private Power Infrastructure Board (PPIB) issued a letter of intent to SK Hydro (Private) Limited for the project in November 2005. In November 2007, the feasibility study of the project was completed and submitted to PPIB which was reviewed and approved in March 2008. As the Khyber Pakhtunkhwa government was in court of law on certain constitutional issues, the project was held up since January 2009.


Voith Hydro has signed a contract to supply machinery and equipment for two small hydropower projects in Colombia’s northwestern Antioquia department.
The El Molino and San Matias hydroelectric plants will be built and operated by HMV Ingenieros. Each will have an installed capacity of 20 MW, Voith said.
The projects will be built in cascade form, meaning the same water that passes through the first plant will be reprocessed to produce power at the second downstream. Voith said the arrangement will “significantly reduce the environmental impact”.
Per its contract, Voith will supply four Francis horizontal turbines and four generators, in addition to governors, automation systems, and engineering, erection and commissioning supervision services.

The 500MW Dungowan project is a pumped hydro energy storage (PHES) power plant, which is proposed to be developed in New South Wales (NSW), Australia.
The project is being implemented by Walcha Energy, a partnership between MirusWind and Energy Estate. It forms a part of the larger 4GW Walcha Energy Project, which aims to develop wind, solar and PHES project at an estimated cost between A$3bn ($2.12bn) and A$6bn ($4.24bn), near the town of Walcha in NSW.
Dungowan pumped hydro storage project location
Dungowan hydroelectric project will be developed on the existing 6.4 megalitre Dungowan Dam, approximately 45km south-west of Tamworth in the New England region of NSW.
The project location is surrounded by deep gorges on the east and Walcha plateau on the south, making the location suitable for pumped hydro storage. The Walcha Energy Project is expected to be a major part of the New England renewable energy zone (REZ), which was proposed by the NSW state government in July 2020.
Dungowan pumped hydro storage project development
Tamworth Regional Council signed a memorandum of understanding (MoU) with Walcha Energy and Arup to study the feasibility of a pumped storage hydro project near the Dungowan Dam in November 2018.
Walcha Energy started working on the next phase of the feasibility study in June 2019. The study will also evaluate the possibilities of water security enhancement through the PHES scheme design and expansion of the existing catchment due to the growing drought in NSW and pressure on water supply for the Tamworth region.
Arup conducted a site assessment study on the PHES development options at Dungowan dam in 2019.
Details of Dungowan hydropower project
The pumped hydro energy storage project has potential for three PHES projects each with a dispatchable electricity capacity of 500MW and storage capacity of eight hours. The project partners identified three separate locations with separate upper and lower reservoirs.
PHES will provide detachable energy supply and help to make up for the lost power capacity from the decommissioning of coal-fired power stations, starting in 2022, and meet the grid demand.
The Dungowan PHES project is part of the ‘Dungowan Renewable Energy Hub’, which falls under phase two of the Walcha Energy Project.
The Dungowan Hub will include a new 810MW transmission line between Liddell and Dungowan.
Walcha Energy received funding for pre-investment studies of the Dungowan PHES under the A$75m ($53.67m) NSW Emerging Energy Programme in 2019. The pre-investment studies include evaluation of commercial, hydrological and technical feasibility of the project.
Walcha Energy Project
Walcha Energy Project comprises renewable energy development of 3.8GW of wind and 700MW of solar and pumped hydro and battery storage projects with a total capacity of more than 4GW in the proposed New England REZ, one of Australia’s largest renewable energy zones.
The project is being developed in four phases. Uralla Renewable Energy Hub will be developed in phase one, Dungowan Hub in phase two, while wind and the solar hubs will be developed in phases three and four with new connections under the latest Integrated System Plan.
The project already includes the 700MW Winterbourne wind farm, 700MW Salisbury solar farm and 700MW Ruby Hills wind farm, which will be unified under the Uralla Renewable Energy Hub.
GE Renewable Energy signed an agreement with Walcha Energy for the joint development of the Dungowan hydroelectric project in August 2020.
GE Renewable Energy Hydro Solutions, a subsidiary of GE Renewable Energy, will provide technical and commercial support for the development of the project.


Background: FERC has announced its receipt of an application for modifications to the existing Lake Byllesby Hydroelectric Project on the Cannon River in Dakota County, Minnesota. The proposed modifications would include repair/replacement of several project features in conjunction with an upgrade to the project’s turbine generator units. The work would primarily involve: (1) construction of gate structures, intake pier, and buttressing; (2) replacement of the project draft tubes, turbines, and other generation equipment; (3) repair or restoration of several historic features of the project powerhouse; and (4) restoration work in the downstream river channel. The replacement of the turbines and related generation equipment would increase the project’s maximum intake design flow from 650 cubic feet per second (cfs) to 1,050 cfs, resulting in an increase in installed generating capacity from 1.9 megawatts (MW) to an estimated 4.0 MW.
- Comments are due by January 7, 2019 and can be submitted via the FERC eFiling portal at http://www.ferc.gov/docsfiling/efiling.asp using Docket ID P-6299-014.

Kumali: With the inflow of water into the Mullaperiyar dam strengthening, four spillway shutters of the Mullaperiyar dam were opened on Sunday morning.
The water level in the dam is at 141.8 feet.
The district collector have issued a warning to the local people on the Periyar banks to be alert as chances of opening more shutters looks imminent.
The Mullaperiyar dam has for long been a bone of contention between the two States of Tamil Nadu and Kerala and has seen a series of legal battles.
Kerala has, citing the weak health of the dam, wanted to cap the water level at 135 feet, while Tamil Nadu fought for a full capacity. The Supreme Court has fixed it at 142 feet.

The Foz Tua hydroelectric plant is situated on the Tua River in a deep valley with dense vegetation in a hard-to-reach region of Portugal. The EUR 260 million project features a double-curved arch dam and a hydraulic system that consists of two underground tunnels. Due to the remoteness of the site and the large amount of concrete required to build the plant, Sacyr Somague was contracted to install platforms and equipment to manufacture the concrete structures on-site.
Sacyr Somague defined an accurate geometric model of the site using MicroStation and OpenRoads and coordinated the dam drawings in MicroStation. The project team used the model to prefabricate the auxiliary structures to decrease waste. The model served to plan the number, size, and weight of the parts that were dismantled and transported to the site. Project collaboration improved productivity, lowering costs and keeping the project on schedule.

Contractors should be ready to begin work by the end of the year on the final stage of improvements to Soniat Canal in Jefferson Parish.
The U.S. Army Corps of Engineers recently awarded an $8.1 million contract to Shavers-Whittle Construction of Mandeville to replace the westbound West Metairie Avenue bridge over the drainage canal. The work is part of an ongoing $36 million canal improvement project under the Southeast Louisiana Flood Control Project, spokesman Rene Poche said in a statement. The corps has been working since 2006 to improve drainage flow in the canal, which sends storm water into Lake Pontchartrain.
The scope of the work includes complete demolition and reconstruction of the westbound bridge to accommodate the improvements made to that part of the canal. Before demolition, contractors will construct a temporary detour bridge to alleviate traffic issues.
Westbound traffic on West Metairie Avenue would be reduced to one lane during construction of the temporary bridge. Poche said the Corps of Engineers is working with Jefferson Parish to adjust traffic patterns.
The project is expected to be complete in August 2015.
The SELA program was federally authorized in 1996. Its goal is to reduce damages from rainfall flooding from a storm with a likelihood of occurring once every 10 years. SELA work includes improvements to about 26 drainage canals, additional pumping capacity for four pump stations and the construction of three new pump stations throughout the parish.

According to the press release, the construction of the dam is estimated at Rs 1406.5 billion. Announcing the commencement of work on the construction of the dam immediately, it was stated that the construction of the dam would be completed in the year 2028.
Similarly, an agreement worth Rs. 442 billion was also signed with the partners of the two companies for the construction of the Diamer Bhasha Dam Project Diversion System, Main Dam, Access Bridge, and 21 MW Tangier Hydropower Project. These are given to a partner called Diamer Bhasha Consultants Group. The Consultant Group consists of 12 companies, the parent company of which is Nespak.
The Water and Power Development Authority of Pakistan (WAPDA) has announced that the contract for the construction of Pakistan’s largest Diamer-Bhasha Dam has been awarded to the Pakistan Army-run Frontier Works Organization (FWO) and the Chinese government. The company is a partner of Power China.
Why is the contract for Mohmand Dam controversial?
According to WAPDA, a contract for consultancy services was also awarded for the construction of the Diamer-Bhasha Dam project. The consultancy services contract worth Rs. 27.18 billion has been awarded to a partner named Diamer Bhasha Consultants Group. The consultant group consists of 12 companies, with Nespak as its parent company.
According to Diamer-Bhasha Dam project sources, Rs 175 billion will be allocated for land acquisition and payments for the dam, resettlement of victims, and local development.
Obstacles to the project
Part of the Diamer-Bhasha Dam will be built in Gilgit-Baltistan, and India has long claimed the Gilgit-Baltistan region.
According to WAPDA sources, the cost of the dam in 2008 was about 12 billion. Pakistan could not provide this huge amount of money from its own resources. Therefore, it was expected that the World Bank, the Asian Development Bank, and the Aga Khan Network would provide capital. But with the launch of the dam project, India had raised objections to the project.
Investment in the construction of the dam was temporarily halted by international organizations over India’s objections. But in 2012/13, despite the efforts of the then government, international institutions made the provision of capital from India conditional on NOC.
Asim Saleem Bajwa has claimed in his tweet that Pakistanis will get 16500 jobs from this project, while 4500 MW of electricity will be generated.
Rs. 791 billion has been allocated for Diamer-Bhasha Dam for power generation and other needs. Rs 480 billion is earmarked for the construction of the Tangier Hydropower Project.
Retired Lt. Gen. Asim Saleem Bajwa, Special Assistant to the Prime Minister for Information, claimed in his tweet that the project would provide 16,500 jobs to Pakistanis and generate 4,500 MW of electricity. He termed the commencement of the construction of Diamer-Bhasha Dam as great good news.
Pakistan considers Diamer-Bhasha Dam essential for electricity and water. Pakistan has not built any major dam since the 1960s.
Diamer Bhasha Dam and its location:
The dam is to be built in Gilgit-Baltistan in northern Pakistan and Bhasha in the border region of Khyber Pakhtunkhwa. Part of it falls in the Kohistan region of Khyber Pakhtunkhwa, while part of it falls in the Diamer district of Gilgit-Baltistan, hence the name Diamerbhasha Dam. The dam will be built on the Indus River. The construction will take place at an altitude of 315 km from Tarbela Dam, 165 km from Gilgit-Baltistan’s capital Gilgit and 40 km from Chilas on the lower reaches of the Indus. According to WAPDA, the height of the dam will be 272 meters. Its 14 spillway gates will be constructed. It will have a total storage capacity of 8.10 million acre-feet, while it will have 6.40 million acre-feet of water at all times.
Gilgit-Baltistan government spokesman Faizullah Faraq claims that the area falls in Diamer district. This area belongs to the Diamer tribes. He said that our people are not against the dam but consider the dam as a guarantor of regional and national development, but before the construction of the dam, this dispute must be resolved.

Scottsdale project to protect against floods
More than 600 properties in Scottsdale will be removed from a floodplain because of the Granite Reef Watershed Drainage Improvements Project.
Scottsdale, the Flood Control District and the Salt River Pima-Maricopa Indian Community will share the cost of the project, with the initial phase estimated at $3.5 million. The complete project is expected to cost $24 million to 28 million.
The initial phase will design the expansion of existing storm drain systems and property acquisition for future detention basins. Future phases will include construction and additional storm drain and channel features.

Goksu River Dam Project
In 1990 a series of seven dams was started in the Goksu River basin in southeastern Turkey. The goal of the dams was to provide long-term hydroelectric power to the region. Landsat satellite data have been used by government officials and by others to study the growth and impact of the dams as the Goksu River is one of the few remaining free flowing rivers in Turkey and the presence of the dams has impacted the aquatic species and wildlife in the area.
The Gezende dam was completed in the early 1990's. The diminished downstream flow of the river significantly affected aquatic species.
The construction, in the early 2000's of the Ermenek dam project created a large reservoir that inundated previous fragile wildlife habitat.

Lesotho launches Polihali Dam Construction Tender
The Lesotho Highlands Development Authority (LHDA) has launched a tender for construction of the Polihali Dam.
The tender marks the start of procurement for the second main works construction, and follows on the issuance in May of the tender for construction of the Polihali Transfer Tunnel.
The Polihali Dam will be a concrete faced rockfill dam (CFRD) similar to the Mohale Dam, which was built during Phase I of the Lesotho Highlands Water Project (LHWP). The embankment will stand approximately 166m high, have a crest length of about 920m and a crest width of 9m. Over 14 million cubic metres of rock which will be quarried locally within the dam basin will be compacted to form the embankment. The dam will create a reservoir on the Senqu and Khubelu rivers with an estimated surface area of 5,053 hectares and a full supply storage capacity of 2,325 million cubic metres. The Polihali Dam infrastructure also includes a 43m high, 600m crest-length CFRD saddle dam, a spillway and a compensation outlet.
The flow from Polihali will increase the volume of water to be transferred from the Katse Dam, the centre point of the Lesotho Highlands Water Project which was constructed during Phase I. The current water transfer volumes to the Gauteng region of South Africa will incrementally increase from 780 to 1 270 million cubic metres per year. This will also simultaneously increase the energy generated by the ‘Muela hydropower plant from approximately 500GWh to 800GWh per year, a further step in the process of securing an independent power supply to meet Lesotho’s domestic needs.
“The launching of the construction of the main works open tender is the culmination of years of planning and hard work of dedicated design and procurement teams. Our objective with this final procurement stage is to attract suitably qualified companies with the capability, experience and resources to undertake the construction of the Polihali Dam within the set timeframes and to the required quality,” stated Tente Tente, CE of the LHDA.
The Phase II Agreement encourages the Project to benefit the economies of Lesotho and South Africa but emphasises the need for procurement that fosters competitiveness, transparency, cost-effectiveness and quality. LHDA’s robust Procurement Policy and tender evaluation protocols will ensure a fair and transparent procurement process.
The launching of the dam construction tender process marks the start of the final construction phase of the water transfer component under Phase II of the Lesotho Highlands Water Project.
Interested construction firms have up to 12 November 2021, to submit tenders. Specific information on the requirements and conditions of the tender is available on the LHDA website.
The Matla a Metsi Joint Venture which comprises Lesotho, South African and international experts: GIBB (Pty) Ltd; MPAMOT Africa (Pty) Ltd; Tractebel Engineering SA; LYMA Consulting Engineers of Lesotho, was awarded the Polihali Dam design and construction supervision contract in 2017.
The Polihali dam construction procurement is launched as construction activity on ten advance infrastructure contracts progresses steadily with some contracts expected to be completed in 2021. Construction of the 33kV line, which will provide a temporary power supply to the Polihali village, was completed in 2020. Work on the 132kV line has advanced with the construction of access roads, 91 tower foundations and the erection of 84 towers out of a total of 93. The Polihali and Katse civil works; access roads, pipe laying for potable water and sewerage lines have been completed, and construction on the main access roads is underway. Excavation on the Polihali diversion tunnels is close to completion with breakthrough on both tunnels expected in the second half of August.
According to the current master programme, water delivery is scheduled for the year 2027/2028. Timely construction of the dam and transfer tunnel is critical to meeting the water delivery deadline of the project.
Phase II of the Lesotho Highlands Water Project builds on the successful completion of Phase I in 2003. It delivers water to the Gauteng region of South Africa and utilises the water delivery system to generate hydroelectricity in Lesotho.
The Lesotho Highlands Water Project (LHWP) is a multi-phased, multi-billion Maloti/Rand project between the Governments of the Kingdom of Lesotho and the Republic of South Africa.
It comprises water transfer and hydropower generation components with associated ancillary developments. The water transfer component entails the construction of dams and tunnels in Lesotho, enhancing the use of water from the Senqu (Orange) River and its tributaries by storing, regulating, diverting and controlling the flow to effect the delivery of specified quantities of water to South Africa, and utilizing the delivery system to generate hydro-electric power in Lesotho.
The major works of Phase I included the construction of the Katse Dam, the transfer and delivery tunnels, Matsoku Weir, ‘Muela Hydropower Plant and the Mohale Dam. The Phase II water transfer component comprises a dam at Polihali and a gravity tunnel that will connect the reservoir at Polihali with the Katse reservoir. The further feasibility studies for the hydropower component of Phase II have concluded that conventional hydropower is the more feasible option to meet Lesotho’s energy needs. Three potential sites were identified: two on the Senqu River and a third site at Oxbow on the Malibamats’o River. The plan is to commission the selected option at the same time as the Water Transfer component, which is 2027.
The Lesotho Highlands Development Authority (LHDA) is the implementing and management authority of the Lesotho Highlands Water Project, on behalf of the government of Lesotho.

● Happy Valley Underground Stormwater Storage Scheme
The project comprises the construction of an underground stormwater storage tank with a capacity of 60,000m3, an automatic operation pump station and the Fan Room and associated drains at Happy Valley Recreation Ground. An underground stormwater storage tank is to be built to temporarily store part of the stormwater collected from the upstream catchment through the downstream stormwater drainage systems. The total contract sum is 711 million HKD and the contract period is from September 2012 to April 2018.
W T Chan & Associates Ltd. is appointed by the Contractor to conduct the ELS design for various structures including but not limited to the Still Basin, Box Culvert, and Irrigation Tank. The main constrains that encountered during the design are the high groundwater table, which is only about 0.5m below the existing ground level; and a layer of Clay material at the excavation level. Due to the high groundwater table and clay material being encountered, the embedment length of the sheetpile wall should penetrate beyond the clay layer for the stability of the sheetpile. Moreover, a layer of strut is proposed close to the final excavation level in order to limit the sheetpile wall deflection due to the ‘soft’ clay stratum.

Design of a New Water Level Meter
Download as PDF
In engineering and experiment, it is often necessary to accurately measure water level, which can be used for flood control and has a significant impact on people's lives. At present, the commonly used methods are image acquisition and recognition, but they are vulnerable to interference, and the accuracy rate is low. In order to reduce interference and improve accuracy, a new technology based on capacitance sensing is adopted. When the water level changes, the parasitic capacitance will change. This change can be detected by a high-precision sensor and converted to the water level value.
