Its 125MW power station will be able to supply 520.8 million KWh of electricity per annum to Dung Quat Industrial Zone, Quang Ngai’s western districts, the neighboring province of Quang Nam, and the national grid.
The DrakDrinh is the main tributary of the Tra Khuc, the largest river in the central province.


Alleviating Severe Flood Risk, Supplying Natural Resources
Liaoning Water Conservancy and Hydropower Survey and Design Research Institute was responsible for delivering the engineering design of the Dongtaizi Reservoir. This project is one of 172 major water conservancy endeavors meant to tackle China’s water scarcity and flood risk issues sponsored by the Chinese government. The proposed infrastructure is a rockfill dam with an asphalt core wall and a concrete gravity dam with a total storage capacity of 321 million cubic meters. Located in the upper and middle reaches of the Xar Moron River in Chifeng, Inner Mongolia, the reservoir will mitigate severe flood risk in the lower reaches of the river and supply water and agricultural irrigation to the areas adjacent to bottom of the river basin.
Challenging Boundary and Structural Conditions
The surveying tasks and engineering specifications on the Dongtaizi Reservoir Project were immense. The site’s complex terrain required an accurate geological survey of the rock mass foundation types and structural plane upon which the dam design would be based. A curved ecological fishway that enables migrating fish to pass through the dam demanded significant excavation that necessitated more than traditional 2D processes. Designing the rockfill dam section involved many control conditions and complicated interactions with the landscape, which cannot be solved with conventional 3D modeling. Additionally, multidiscipline engineering and visualization capabilities were essential to design the metal structure, hydraulic machinery and engineering, and an electromechanical system. Therefore, Liaoning Water realized that they had to adopt building information modeling (BIM) solutions to overcome traditional design limitations on this large-scale water conservancy project.
BIM Applications Overcome Traditional Design Restrictions
After considering their options, the team employed Bentley’s BIM software for accurate 3D design. Liaoning Water integrated OpenBuildings and OpenRoads Designer to streamline collaboration among multiple engineering disciplines and to manage data. They surveyed the landscape and created a detailed 3D geological model to precisely calculate excavation volumes and plan excavation processes. This visualization in OpenRoads also allowed the project team to accurately position the ecological fishway and connect the structure’s complicated spatial curve to the landscape. The rockfill dam section was designed using OpenRoads’ linear engineering capabilities to generate a truthful 3D model incorporating all control and boundary conditions. Several engineering disciplines collaborated on the design of the concrete dam in OpenBuildings, allowing the hydraulic machinery, metal structure, and electromechanical equipment to be designed to avoid collisions.
Leveraging BIM Technology to Deliver a Digital Twin
By using Bentley applications, Liaoning Water reduced design error by 90%. Delivering a technologically advanced model minimized changes to the overall design during construction. Accurately calculating project cost in the design stage of the project decreased the government’s overall investment. With the support of open modeling technology, the project team improved design efficiency by 40% to deliver the plans two weeks ahead of schedule. They leveraged BIM software to produce a digital twin that provides full lifecycle support of the dam, including management during construction, operations, and maintenance. Using this project as the foundation for BIM usage on future water conservancy projects, Liaoning Water has implemented corporate 3D collaborative design standards and trained personnel to become a regional leader in BIM application.
- The Dongtaizi Reservoir Project is one of 172 major water conservancy projects in China and one of 12 key livelihood projects in Inner Mongolia meant to mitigate severe flood risk and combat water scarcity.
- Complex terrain and infrastructure design required 3D modeling solutions to quantify structural elements and excavation amounts.
- Using BIM applications reduced design error by 90%, avoiding design changes and rework during construction.
“The use of Bentley software has solved the important and difficult problems in the engineering design of Dongtaizi Reservoir, provided strong endorsement for designers, improved the design efficiency of our institute, reduced design errors, and made the digital transfer of design results possible.”

African Development Bank (AfDB) has approved 115 million dollars, which is the third round of loans to finance the construction of the cross boarder electricity transmission line project between Ethiopia and Kenya, last week. Three months earlier, the AfDB approved the second phase of funding for the project with 348 million dollars.
The 1.26 billion dollar project is a 1,068Km high voltage transmission line with a power transfer capacity of up to 2,000Mw. The project will position Ethiopia as the main powerhouse and Kenya as the main hub for power trading in the East African region; and on completion the project will promote power transfers, economic trading and regional integration, according AfDB.
The completion of the Ethio-Kenya power line will enable Ethiopia to start substantial electricity exports to Kenya. It currently exports electricity to Djibouti and Sudan. Overall, Ethiopia plans to invest over 12 billion dollars to increase its hydropower generating capacity from the current level of 2,000Mw to 10,000Mw by 2015, and then to over 40,000Mw by 2035, making the country Africa's largest power exporter.


Two key projects aimed at restoring Louisiana’s coast will move forward after receiving almost $200 million for engineering and design work.
The Gulf Environmental Benefit Fund awarded the money, which is part of the $370 million designated for 24 projects in Louisiana, Texas, Florida, Alabama and Mississippi, on Nov. 15. The fund was created using oil giant BP’s $2.5-billion settlement for the Gulf oil spill.
About $102.3 million will be used to complete the engineering and design for the $1.3-billion mid-Barataria sediment-diversion project.
The project is expected to move up to 75,000 cu ft per second of sediment-laden Mississippi River water into the Barataria Basin to create new land.
Lafayette, La.-based HDR Engineering has completed some preliminary engineering for the project.
The engineering and design of the project will include a gravity flow structure, a conveyance channel and relocation of a road, a rail line, utilities and pipelines.
The smaller but similar mid-Breton sediment-diversion project received $90.7 million to begin and complete engineering and design. The $700-million project will move 35,000 cfs of river water to rebuild Breton Sound.
Another $16.1 million was provided to manage both of the diversion projects, located on opposite sides of the river in Plaquemines Parish.
Engineering and design for the projects are expected to take until 2020, when construction is anticipated to begin.
The Louisiana Coastal and Restoration Authority, which oversees Louisiana’s coastal projects, will let the projects for bid next year, said Chuck Perrodin, spokesman for Louisiana’s coastal authority, but he did not have a more definite time frame.

The 462MW Chaglla hydroelectric power plant, developed by Odebrecht Energia’s subsidiary Empresa de Generación Huallaga (EGH), is Peru’s third-biggest hydropower project.
Construction of the project began in May 2011 and operations commenced in 2016. The plant has an operational life of 30 years. It required a $1.2bn investment and produces approximately 2.8GW/h a year while offsetting approximately 467,000t of carbon dioxide emissions from the atmosphere.
In August 2017, Odebrecht Latinvest entered an agreement with a consortium led by the China Three Gorges Corporation (CTG) to dispose of the Chaglla hydroelectric plant.
Chaglla power plant design and development
The Chaglla hydroelectric project is located on the Huallaga River in the Chaglla district of Huanuco, Peru. It includes a concrete-face rock-filled dam, which impounds a 4.66km² reservoir upstream of the dam, diversion tunnel and hydroelectric generation facilities, comprising a powerhouse, substation and transmission line.
The rock-filled dam has a maximum height of 202m and a crest length of approximately 273m, while the crest of the dam is located at an elevation of 1,202m above sea level and 11.2m-wide.
The reservoir has an elevation of 1,196m and a water surface area of 4.5km². It has a storage capacity of approximately 375 million cubic metres, and three tunnels with a total length of 2,850m were built on the left margin for spillway discharge.
In addition, the plant features two turbine generators with a nominal output of 253MVA and frequency of 60Hz. These turbines have a nominal voltage of 13.8kV and operate at a synchronous speed of 900rpm.
Water from the dam is diverted through a 14.7km intake tunnel to the main powerhouse, which is equipped with two Alstom power transformers with a nominal output of 225MW. The project also features a small powerhouse, including a power transformer with an output of 6MW.
The substation is situated above the main powerhouse at an elevation between 900m to 925m.
Power transmission from the Chaglla power plant
The power generated by the plant is transferred to the Peruvian national grid (Sistema Electrico Interconectado Nacional-SEIN) at the Paragsha substation, via a 137km-long, 220kV transmission line.
Construction of the hydropower project
Four sites were created for the construction phase. Major works include the construction of the concrete-face dam with a 466ha reservoir, a surface powerhouse and a 1,053m-long diversion, spillway and headrace tunnel. For the foundation and dam construction, an upstream and downstream cofferdam was constructed at 1,068m and 1,009m respectively.
Construction works also included the river bypass through trunk tunnelling, which has a diameter of 12.5m and length of 1,125m. The upstream cofferdam measures 66m, while the downstream is 14m-high.
Inter-American Development Bank (IDB) provided a $150m loan facility to Odebrecht Energia for the hydroelectric power plant.
The project was also co-financed by Banco Nacional de Desenvolvimento Econômico e Social (BNDES), COFIDE (Development Finance Corporation), and other international commercial banks, while BNP Paribas acted as the financial advisor.
Alstom was awarded a contract to supply all the hydro and electromechanical equipment, spare parts and services. The scope of supply included two generation units with a total power of 450MW, power transformers and switchyard equipment, as well as the complete mini hydropower plant.
Mott MacDonald was engaged by The Bank of New York Mellon as the independent engineer to monitor the power plant construction. The contractual scope included providing support for the lenders in the construction, operations and monitoring phases of the project.


Executive Mayor, Melvin Naik today officially opened the construction site for the raising of the Garden Route Dam spillway project with a Sod Turning ceremony. The construction works on the dam wall and spillway area started on 13th May this year.
“This is a first for George and the Western Cape, the project design is unique and I would like to thank all role-players within George Municipality and externally who started with the planning of this project as far back as December 2008. Given the uncertain impact of climate change and the future expansion of George, I am excited about this project which is part of the Grow George initiative, increasing the storage capacity of this precious resource is a positive step for the future development of George. I wish only success to the project and everyone involved here today,” said Naik.
The dam’s full supply level will be raised by 2.5 metres, which will increase the total storage capacity of the dam by approximately 25%. The current weir height is 179,94m with a volume capacity of about 10.0 million cubic metres. The new weir height will be 182,5m with a storage capacity of approximately 12,5 million cubic metres. The construction period is still estimated to be ten months from time of contractual commencement and the site and an extended surrounding area remains closed to the public for safety reasons. The fill for the raising of the dam wall will be excavated on the MTO/NMU side of the dam and transported to the construction site and it is expected that approximately 13 000 cubic meters of material will be transported.
The new spillway will be approximately 80m in length and varies between 3.7m to 4.7m in height (above existing ground levels) and approximately 400 to 600mm thick at the top of new spillway wall. Hydraulic testing on the spillway design was done at the Department of Water and Sanitation’s (DWS) Hydraulic Laboratory in November 2017 and was undertaken to substantiate the computer modelling simulation undertaken by Aurecon. The model tested as calculated and was accepted as such by DWS.

Check valves are classified according to their structure and installationRelease Date: October 04, 2019
Check valve can be divided according to its structure and installation:
1. Swing check valve :
The flap of the swing check valve is disc-shaped, and rotates around the rotation axis of the valve seat passage. Because the passage inside the valve is streamlined, the flow resistance is smaller than that of the lift check valve, which is suitable for low flow rates and flow. Large-caliber occasions that often change, but it is not suitable for pulsating flow, and its sealing performance is not as good as that of lifting type. Swing check valve is divided into three types: single, double and multiple. These three types are mainly divided by the valve diameter, in order to prevent the hydraulic shock when the medium stops flowing or flows backward.
2. Lift check valve:
The check valve with the valve disc sliding along the vertical centerline of the valve body. The lifting check valve can only be installed on horizontal pipelines. On the high-pressure small-diameter check valve, the valve disc can be a ball. The shape of the valve body of the lift check valve is the same as that of the shut-off valve (can be used with the shut-off valve), so its fluid resistance coefficient is large. Its structure is similar to a globe valve, with the same body and disc as the globe valve. The upper part of the valve disc and the lower part of the valve cover are processed with a guide sleeve. The valve disc guide can be freely raised and lowered in the valve guide. When the medium flows, the valve disc is opened by the thrust of the medium. When the medium stops flowing, the valve disc is Falling down on the valve seat, it plays a role in preventing the medium from flowing backward. The direction of the inlet and outlet channels of the straight-through lifting check valve is perpendicular to the direction of the valve seat channel; the vertical inlet and outlet check valve has the same direction of the medium inlet and outlet channels as the valve seat channel, and its flow resistance is smaller than that of the straight-through valve.
3. Butterfly check valve:
Non-return valve in which the disc rotates around a pin in the valve seat. The butterfly check valve has a simple structure and can only be installed on a horizontal pipe, which has poor sealing performance.
4. Pipeline check valve:
A valve whose valve disc slides along the centerline of the valve body. Pipeline check valve is a new type of valve. Its small size, light weight, and good processing technology are one of the development directions of check valves. However, the coefficient of fluid resistance is slightly larger than that of the swing check valve.
5, compact check valve:
This valve is used as a boiler feed water and steam shutoff valve, and it has the integrated function of a lift check valve and a stop valve or an angle valve.

Preliminary Models Relating Lake Level Gate Operation and Discharge at Reelfoot Lake in Tennessee and Kentucky
- Document: Report (2.57 MB pdf)
- Data Release: USGS data release— Preliminary model data for lake level gate operation and discharge at Reelfoot Lake—Tennessee and Kentucky
- Database: USGS water data for the Nation— U.S. Geological Survey National Water Information System database
- Download citation as: RIS | Dublin Core
Preliminary models for gate operations at the new outlet control structure for Reelfoot Lake were developed by the U.S. Geological Survey, using calibrated ratings of the lift gates, to support the U.S. Fish and Wildlife Service in managing lake level. In 2018, the old structure at the outlet of Reelfoot Lake was buried and lake level control was transferred to a new structure. The transition from lake-level management of the old control structure to the new control structure was documented using historical lake level and discharge measurements and records of stop-log management from March 7, 2013, to August 12, 2018. Discharge into Running Reelfoot Bayou was determined using a standard stage-discharge rating curve. Discharge measured using an acoustic Doppler current profiler was used to calibrate gate-discharge equations for free and submerged orifice flow at the new structure.
Two lake operation models, one for the summer season and another for the winter season, are provided for the new structure based on data from this period. The summer operation model is based on operation of the gates once the lake level exceeds an elevation of 282.7 feet (ft) above the North American Vertical Datum of 1988 (NAVD 88). Free flow begins when lake level reaches 282.3 ft above NAVD 88 and becomes transitional once the lake level exceeds 282.8 ft above NAVD 88. Submerged flow begins once the lake level reaches 283 ft above NAVD 88 and the tail-water depth is above critical flow depth. The winter operation model is based on operation of the gates once the lake level exceeds 283.2 ft above NAVD 88.

The Central Interceptor is a major wastewater tunnel being constructed in Auckland, New Zealand.
AWMA has been engaged by head contractor, Ghella Abergeldie Joint Venture and their client Watercare.
AWMA were required to custom design, manufacture and supply a range of regulating and isolating water control structures.
The Central Interceptor tunnel will run underground for 14.7km. Travelling from Grey Lynn to the Māngere Wastewater Treatment Plant, the tunnel will pass multiple shafts and chambers being constructed as part of the project to connect the existing waste water systems.
AWMA’s contribution involves the specialised design, manufacture and supply of gates to be installed in the control and diversion chambers and shafts along the route, which will be used for collecting and transferring wastewater into the tunnel.
The wastewater control gates currently progressing through AWMA’s design and engineering phase include hydraulically actuated slide gates, electrically actuated slide gates, stoplogs, stop plates and flap gates.
All water control gates will be manufactured from Duplex 2205 and 2507 stainless steel for strength and longevity in the highly corrosive environment.

The Panjiakou Dam is a concrete gravity dam on the Luan River in Qianxi County, Hebei Province, China. The primary purpose of the dam is to provide water for the cities of Tianjin and Tangshan, located to the south. The dam also provides flood control and its power plant has an installed capacity of 420 MW which includes a 270 MW pumped storage power station.
Construction on the first stage of the project began in 1975 and the single 150 MW generator was operational in 1981. In 1984, the first stage was complete and in the same year, construction on the second stage began. This consisted of the lower reservoir and pump-generators for the pumped storage power station. In 1989, the lower reservoir began to impound and in 1993, the pump-generators were operational. Water supplied by the dam is used for industrial, agricultural and municipal needs in Tianjin and Tangshan. When the Panjiakou Reservoir was filled, it submerged the town of Panjiakou under 50 m (164 ft) of water. Located in the hills above the town is a section of the Great Wall, part of which was submerged as well. The submerged section ran through Panjiakou pass and a portion can be seen on a small island off the reservoir's edge at , particularly during droughts when the reservoir holds less water. The scenery around the reservoir is a popular tourist destination and with the surrounding terrain, it is often called "Qianxi Little Three Gorges".
Design and operation
The Panjiakou Dam is a 107.5 m (353 ft) tall and 1,040 m (3,412 ft) concrete gravity dam. The dam's reservoir has a capacity of 2,930,000,000 m3 (2,375,390 acre⋅ft) and surface area of 67 km2 (26 sq mi). Of the reservoir's capacity, 1,950,000,000 m3 (1,580,891 acre⋅ft) is active (or "useful") for power generation and water supply. The dam sits at the head of a 33,700 km2 (13,012 sq mi) catchment area which constitutes 75 percent of the Luan River basin. The dam's spillway is located on its left face and contains 18 floodgates. It has a maximum discharge capacity of 40,400 m3/s (1,426,713 cu ft/s). To the right of the spillway is the power house which contains one 150 MW Francis turbine generator and three 90 MW reversible Francis turbine pump generators. Located 5.5 km (3 mi) downstream is the lower reservoir dam. It is a gravity type and has a height of 28 m (92 ft) and length of 1,010 m (3,314 ft). It creates the lower reservoir with a storage capacity of 36,180,000 m3 (29,332 acre⋅ft) of which 10,000,000 m3 (8,107 acre⋅ft) can be used for pumped storage power generation. When the pumped storage capability is used, the Panjiakou Reservoir serves as the upper reservoir and water is released down to the three pump generators for power production. It is subsequently discharged into the lower reservoir. This occurs during periods of high peak power demand. When power demand is low, usually at night when electricity is cheaper, the turbines of the pump generators reverse and pump water back into the upper reservoir. This process repeats as needed. A small power plant on the lower reservoir dam contains two 5 MW Kaplan turbine bulb-generators.

Zlatoličje power plant: the number one power plant in terms of energy generation
This power plant generates more than a fifth of all the electric power generated by Dravske Elektrarne Maribor and makes use of the energy potential of the Drava River between the cities of Maribor and Ptuj where the river turns into a flatbed. Due to its location, it has been designed as a channel-type power plant.
The Zlatoličje HPP makes use of the 33 m head and after refurbishment between the years 2007 and 2012, generates annually 577 GWh of electricity with a threshold capacity of 126 MW. The power plant, built between 1964 and 1969, has a supply and discharge channel separate from the riverbed, a 4,5 million m3 reservoir and a dam structure in Melje near the city of Maribor.
The reservoir is 6,5 km long and lies entirely within the area of the city of Maribor. A lateral embankment with concrete lining preventing leakage of water into adjacent lower lying areas was built alongside the Melje industrial zone. The dam structure consists of six 17 m wide spillways with radial gates and top flaps. The spilling capacity of the dam is 4200 m3/s. A small hydroelectric power plant has been installed in the Melje dam structure.
The 17,2 km long supply channel is trapezium shaped and partially buried, while the majority of it runs in a dike raised above ground level. The side and bottom walls are coated with a waterproof concrete lining with. At the mouth of the canal, a spillway to the Drava riverbed is located, preventing any dangerous rise in water levels. The high-rise powerhouse in Zlatoličje has two overhead travelling cranes. The Kaplan turbine units are vertical and two main transformers are located outside the powerhouse. The plant is connected to the Cirkovce substation via a double 110 kV transmission line. At the intake and outlet, cranes are installed for the placement of stoplogs for maintenance. The intake crane also serves for the cleaning of the trashracks.
The discharge channel with a length of 6,2 km is also trapezium-shaped and buried deeply. Downstream from the powerhouse, a 300 m portion of the discharge channel is lined with concrete plates. Just before Ptuj, water is discharged back into the Drava River.
After refurbishment the capacity of the Zlatoličje HPP has increased by 12 MW which has been achieved primarily by installing new, high-quality primary unit equipment.

Update as of August 7
The average level of the lower reservoir at the Dnipro HPP dam is 14.74 m BS.
The development of the pilot project for the restoration of the Kakhovka HPP will take two years. At the first stage, it is planned to design a temporary reservoir dam. After de-occupation, this will help to quickly begin construction of a temporary hydraulic structure to block the reservoir and, in the event of a flood, help fill it with water to the required level.
Ukrhydroenergo's HPPs and PSPPs continue to restore capacities lost during the shelling, conduct scheduled maintenance campaigns, and actively prepare for the 2023-2024 winter load.


1. As the channel within the valve is in streamline form, the flow resistance of the swing check valve is smaller than that of the lifting check valve. It's suitable for low flow and large-caliber applications without frequently change in flow. However, it's not suitable for pulsating flow for sealing performance poorer than that of the lifting check valve.
2. A swing check valve is suitable for various working conditions of pipeline for petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry.
3. The swing check valve is suitable for the clean medium like water, oil, steam, acid medium, but not suitable for medium with solid particles and great viscosity.


Introduction to localization of pumped storage Static Inverter SFC
The capacity of the reversible unit of the large pumped storage power station is relatively large. When it enters the working condition of the water pump and starts as the motor, if it is directly incorporated into the power grid, it will cause certain impact on both the power grid and the unit, inverter needs to be configured to start the unit from static to grid-connected.
The static frequency converter is the preferred drag equipment for the pump start-up of the pumping and storage power station unit. It can not only drag the unit from the static state to the rated speed, but also realize the integration of the unit without impact, it can also flexibly stabilize the unit at a certain set speed.
At present, the foreign SFC equipment used in the start-up of pumped storage units in China mainly include: ABB, CONVERTEAM (Including ALSTOM)
, GE, Siemens, GANZANSALDO and other manufacturers of products.
Among them, Panjiakou, Yixing, Tai'an, Xilongchi, Qingyuan, xiangshuijian, Xianyou, Hohhot and other power stations have been built using abb sfc equipment;
Tianhuangping, Guangzhang Phase I, Ming Tombs, Tongbai, Baoquan, Huizhou, Bailianhe, Pushi River and other completed pumping and storage power stations use CONVERTEAM SFC equipment;
The SFC equipment of Siemens company has been put into use in the second phase of Guangchang and Xianju pumping and storage power station;
The SFC equipment of GE company has been put into use in Liyang pumping and storage power station;
The SFC equipment of ganz ansaldo company in Hungary is used in Paradise and Huilong pumping and storage power station, and has been replaced by domestic Nanrui Jibao SFC equipment.
Imported static inverters are imported with the main engine. Over the years, the imported SFC system equipment technology has tended to be perfect and the operation tends to be stable, which basically meets the operation requirements of pumped storage units.
However, there are still more and more prominent problems of technical support or spare parts in the imported SFC system.
The construction of a large number of pumped storage power stations in China requires the gradual localization of major equipment matched with them.
Reversible pumped storage unit, static frequency conversion starting equipment (SFC)
They are the main equipment, key and important equipment of pumped storage power station, which requires the localization of static frequency converter as soon as possible.
The first domestic Static Inverter developed by Nanrui group was put into operation in Panjiakou pumping and storage power station in Hebei province in April 2010, and Nanrui Jibao's domestic SFC equipment for Anhui xiangshuijian pumped storage power station was put into operation in April 2014.
Through the implementation of several projects, China has fully mastered the design, manufacture, commissioning and other technologies of the complete set of static inverter equipment for pumped storage power stations.
At present, the domestic Static Inverter Products have been extended to infrastructure projects of pumped storage power stations and renovation projects of old Static Inverter equipment.
Now, the infrastructure projects of Fengning power station in Hebei and Jixi power station in Anhui as well as several projects which just started the host calibration in 2018 also basically adopt the domestic SFC, the second phase of Guangzhou Pumped Storage Power Station, Henan Huilong pumped storage power station and Hubei paradise pumped storage power station have adopted domestic SFC equipment.

Amberwood Subdivision Drainage Improvements
The Amberwood Subdivision Improvements Project consisted of replacing an existing, failing drainage system with a system capable of passing a 100-year storm without the flooding that had been a recurring problem. This project included permitting and construction of a new drainage crossing of Highway 98, without any closures.
Key to the accomplishment of the design objectives, Fabre Engineering developed a stormwater flow model that satisfied FDOT’s concerns, and indicated that the proposed improvements would actually decrease the flood stage of a 100-year storm at the Highway 98 crossing. Lack of this analysis had previously been an insurmountable obstacle to obtaining FDOT approval of proposed improvements.
