Submersible tubular pump is particularly suitable for ultra-low head (net head less than 2 m) pumping station which can reduce the excavation depth, lower engine room height, simplify hydraulic structure, and save civil engineering costs. Submersible tubular pump with smaller motor unit can reduce the flow resistance. The flow field inside the submersible tubular pump is simulated in a commercial computation fluid dynamics (CFD) code FLUENT. The RNG k-ε turbulent model and SIMPLE algorithm are applied to analyze the full passage of a submersible tubular pump, the performance of pump such as head, shaft power and efficiency are predicted based on the calculation of different operating conditions. The simulations are carried out over a wide range of operating points, from 0.8 of the reference mass flow rate at the best efficiency point (BEP) to the 1.28 of the BEP flow rate at the same rotating speed. For verifying the accuracy and reliability of the calculation results, a model test is conducted. The comparison of simulation results and the experiment data show that the calculation performances are agree with the experiment results in the high efficiency area and large discharge condition, but in the condition of low discharge, it exists deviations between the two results. Compare with the numerical simulation and experiment, which can provide more evidences for the hydraulic performance prediction and optimization design of submersible tubular pump pumping system.

A joint venture led by Italian firms Impregilo and CMC has been awarded a contract by Eskom Holdings to construct the underground works and reservoirs for the Ingula pumped storage project in South Africa.
The Ingula plant is being built about 350km south east of Johannesburg, on the border between KwaZulu-Natal and the Free State. It is scheduled to be operational in 2013.
Impregilo said that the construction contract was worth approximately Euro600M (US$795M), and it has a 40% stake in the JV.
The project involves linking the Bedford Stream upper reservoir to the powerhouse via an approximately 2km long headrace tunnel. The water will be discharged to a lower reservoir through a tailrace tunnel of about the same length.
Construction works on the scheme include caverns, tunnels, adits, shafts and penstocks, installation of the pump-turbines, and construction of the dams for the upper and lower reservoirs.
Last year, Eskom awarded Voith Siemens Hydro Power Generation the contract to supply electro-mechanical equipment to the project. The plant will be supplied with four pump-turbines, each of 342MW rated output, in a contract worth approximately Euro140M (US$186M).

The total volume of water stored in the reservoir system at the start of this runoff season is expected to be 8.3 million acre-feet, less than the full pool designed to provide water downstream at reduced levels through a 12-year drought such as the one in the 1930s, the corps said.
To conserve water, releases from Gavins Point Dam in northeast Nebraska are being scheduled at the lowest level possible this winter while still serving municipal, industrial and power-plant water intakes at Omaha and other places along the lower river, said Jody Farhat, chief of the corps' Missouri River water management division.
Releases will be stepped up in mid-March for the navigation season, which will open April 1 at the mouth near St. Louis.
The reservoir behind Gavins Point will gradually be lowered 1.3 feet by the end of February to make room for potential spring runoff.

Eastmain-1-A and Rupert diversion project
Step in the procedure
Certificate of authorization issued on Novembre 24, 2006.
Information on the projet
This project involves the partial diversion (71%) of the waters of the Rupert River starting at kilometre 314. The diverted waters are routed north through the La Grande River to increase the power produced at the Robert-Bourassa, La Grande-2-A and La Grande-1 powerhouses. Annual production is assessed at 8.5 TWh.
On the reduced-flow section of the Rupert River, the proponent has constructed eight hydraulic structures to prevent exposure of the riverbanks, among other things. The project also included the creation of the upstream and downstream Rupert diversion bays, including the construction of dams on the Lemare and Nemiscau rivers and several dikes, as well as the construction of a transfer tunnel for the movement of water between the two diversion bays. The construction of the Eastmain-1-A powerhouse, with an installed capacity of 768 MW, and the Sarcelle powerhouse, installed capacity of 150 MW, were integral parts of the project.
The project also included the construction of the permanent Muskeg-Eastmain road, 40 km in length, and a 101 km, 315 kV transmission line. Several temporary camps to house 5,500 workers were also planned. The cost of the project, including the cost of financing, was estimated at $4 billion.
Since 2006, the project has been subject to numeros conditions arising from the initial certificate of authorization and subsequent amendments, generating numerous follow-ups also reviewed by COMEX.
Details on location
The Eastmain-1-A and Rupert diversion project extends over a large part of the Eeyou Istchee James Bay Territory (formerly known as the Municipality of James Bay). To the south, a dam at km 314 on the Rupert River diverts part of the river’s flow northward. There are 8 hydraulic structures on the Rupert River between km 0 and 314. To the north of the Rupert, dams were built on the Lemare and Nemiscau rivers, and the Rupert diversion bays were created.

Construction of a new reservoir and water mains has commenced in Triabunna, Tasmania, to upgrade water infrastructure and improve water security for the local area.
The scale of the project includes the construction of the new 6m-high reservoir and drilling under the existing road to install 800m of water mains.
TasWater’s Capital Delivery Office Project Manager, Nathan Toomer, said these improvements will provide great benefits to the community.
“We are constructing a 2ML storage reservoir and new water mains which will be installed on Selwyn Street, Tapner Court, Ryan Place, Howells Place and Roberts Street,” Mr Toomer said.
“This project will improve water pressure for residents and provide better fire protection capabilities for local emergency service personnel to better protect the community.
“Once complete, it will also support future development and growth of the town while ensuring the infrastructure is compliant with current guidelines.”
This project is part of TasWater’s commitment to delivering new and upgraded water infrastructure improvements in the Glamorgan Spring Bay area and forms part of the $1.1 billion capital works program over the next four years.
This program of works, undertaken by TasWater’s Capital Delivery Office, has boosted local employment with about 93 per cent of all contracts to upgrade or build new infrastructure going to Tasmanian businesses.
The new reservoir and water main project for Triabunna is anticipated for completion before the end of 2022, with Fulton Hogan carrying out the work as the main contractor.

Polavaram project is a multipurpose irrigation project. The primary motive behind the construction of this project was to overcome the deficiency of water. This would require a combined network of 30 river links. After 4 chief ministers rule over the Andhra state, Polavaram project is still in the dream state only. Chandrababu Naidu said that the project would be completed by 2018 at any cost but the Union government said the project cannot be completed before 2021 in the current situations.
In a reply to Congress Rajya Sabha member Renuka Chowdary’s question, Sanjiv Kumar Baliyan, the Union water resource minister said that only 1900 crores have been spent on Polavaram project past 3 years and only 24 % of main canal works have been completed. More than 96% of the work has to be completed for the project to be able to release water.
The current pace at which the project is moving, Polavaram project wouldn’t stand to see the light before 2021. Even Chandra Babu Naidu seems to have lost hopes that the project would be completed by 2018

Prime Minister Narendra Modi on Sunday inaugurated the Sardar Sarovar Dam. It is the second biggest dam in the world on the Narmada river in Gujarat. It is said that the project has helped transport the waters of the Narmada river to the water-Exiguous areas of Gujarat through an detailed canal and pipeline network.
Activist Medha Patkar has been on indefinite fast since 27 July soliciting proper resettlement of Sardar Sarovar Project-oustees, from Chikhalda in Dhar district.
Thousands of families along the Narmada river in Madhya Pradesh’s Barwani, Dhar, Alirajpur and Khargone districts are at risk of getting displaced with the closing of gates of Sardar Sarovar Dam in neighboring Gujarat and resultant rise in the water level in its catchment area.


In this study a new grated inlet is proposed for small roads which do not have storm water collection systems. A setup was designed and constructed in the laboratory conditions to calibrate the grated inlet. The inlet is suggested to be installed at the end of the road where the road itself joins to another road or to a street. Thus, newly installed inlet will collaborate with existing storm water collecting system of the main road. Inlet structure covered by slots is installed across a 0.90-m wide flume which will act as a small road. The slots are longitudinal and parallel to the flow direction in order to curtail clogging. It is a tilting flume and both subcritical and supercritical flow regimes can be observed. The intercepted flow by the inlet is measured and the efficiency of the inlet is obtained in terms of longitudinal slope and the Froude number. It is observed that the grate efficiency gets higher as the longitudinal slope approaches to horizontal. Further the grate efficiency also depends on the total flow through the channel. As flow increases in the channel, the efficiency of the grate increases within the limit of the inlet or discharge channels capacity.

Seven Oaks Dam Project: The Santa Ana River Mainstem Project includes the Seven Oaks Dam as a major feature. Seven Oaks Dam accounts for $450 million of the total $1.7 billion project cost. The structure is a 550 feet high earth and rock fill dam with a crest length of 2,980 feet. In early 1990, a contract was issued for testing and abutment stripping. Actual dam construction began in 1993. Completion of embankment and outlet contracts were in 2000. Care was taken during construction of the dam to insure the continuous function of the local water purveyors on the Santa Ana River. Incidental water conservation and control is a valley wide benefit as well as the purchase of 787 acres of Upland habitat, 760 acres of habitat for the Woolly-Star, San Bernardino Kangaroo Rat and the Slender-horned Spineflower—all protected species.
Description: The construction of the Seven Oaks Dam, 35 miles upstream of the Prado Dam, is a part of the Santa Ana River Mainstem project. Besides Seven Oaks Dam, this $1.7 billion project involves raising existing Prado Dam, channel construction along 23 miles of the Santa Ana River downstream of Prado Dam and channel construction on several tributary streams. The project will provide annual benefits of about $140 million to 160 square miles of urban development, mostly in Orange County, although many benefits accrue to the counties of Riverside and San Bernardino. The Santa Ana River Mainstem Project provides the necessary flood protection for over two million people and hundreds of square miles of developed lands within Orange, Riverside and San Bernardino Counties. The Corps of Engineers has estimated damages of approximately $15 billion could occur in the three counties without the protections of this project.

Check valve is the popular valve which widely used in different industries, today WESDOM will introduce to you some check valves.
A check valve whose disc slides along the vertical centerline of the valve body. Lifting check valves can only be installed on horizontal pipelines. Balls can be used for discs on high-pressure small-diameter check valves. The shape of the valve body of the lift check valve is the same as that of the globe valve (it can be used in common with the globe valve), so its fluid resistance coefficient is larger.
Its structure is similar to the globe valve, and the valve body and disc are the same as the globe valve. The upper part of the valve disc and the lower part of the valve cover are machined with guide sleeves. The valve disc guide can be freely lifted and lowered in the valve guide. When the medium flows downstream, the valve disc is opened by the thrust of the medium. It falls vertically on the valve seat to prevent the reverse flow of the medium.
The direction of the medium inlet and outlet channels of the straight-through lift check valve is perpendicular to the direction of the valve seat channel; the vertical lift 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 type.
The disc of the swing check valve is disc-shaped and rotates around the shaft of the valve seat passage. Because the passage in the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for large-diameter occasions with low flow rate and infrequent changes in flow, but it is not suitable for pulsating flow, and its sealing performance is not as good as that of lifting type.
The swing check valve is divided into three types: single-lobe type, double-lobe type and multi-half type. These three types are mainly divided according to the diameter of the valve.
The butterfly check valve is similar in structure to the butterfly valve. The main difference is that the butterfly valve must be driven by external force as a shut-off valve, while the butterfly check valve is an automatic valve and does not require a driving mechanism. When the medium stops flowing or flows back, the disc rotates to the valve seat by its own weight and the action of the backflow medium.
This check valve can be used on both horizontal and riser pipes and is usually wafer mounted. Under the action of fluid pressure, the two discs rotate around the pin shaft against the spring force, and the opening state is a bit like a "">" sign. There should be some straight pipe sections at the inlet and outlet of the valve, because the valve disc must have a certain space for rotation.


(12/1/12) The U.S. Army Corps of Engineers will officially close the navigation system on the Upper Mississippi next Monday.
The shipping season is ending. It started back on March 17th. Traditionally, the last tow heading south of Lock and Dam 2 near Hastings means the end of the season. The tow Show Me State went through the lock last Wednesday. While the Mississippi River hasn’t frozen over yet, the Corps plans to start winter renovation and repairs on Lock and Dam 6 near Trempealeau Monday.


Compact regulator with rotating plate
suitable for the greatest discharges
no electrical power required
Modern hydraulic management concepts require throttling devices to be considered. The ideal is where the flow curve is perpendicular providing a constant discharge. Throttling controls are required for foul and surface water systems, for watercourses and river control. These regulating devices are required to provide precise discharge control throughout the regulating range.
The HydroSlide® Flow Regulator Type MINI is a simple, robust stainless-steel designed regulator with brass / PE bearings. The compact design makes it possible to enable simple control structures to be designed to house this regulator. Its compact design guarantees a high degree of reliability whilst remaining practically maintenance-free. The MINI regulator is designed to continually regulate the flow rate throughout the operating range of water level. The regulating of the discharge begins when the water level rises. The float rises as the water level increases which in turn rotates the orifice plate to reduce the orifice area to maintain a constant head / flow relationship. The constant discharge flow is attained from an impounding head of approx. 1.0 x DN.
The robust mechanics of the HydroSlide® Flow Regulator Type MINI, make it an ideal choice for flood retention operations.
- no external power source, no electricity
- perpendicular Q/H line
- simple, low-cost flow regulator
- range from small to largest impounding heads
- for small structures
