During his recent visit to China and Henan, Alimak’s segment manager for underground construction and mining Karl-Östen Holmberg signed a contract to supply two 400m ALIMAK Raise Climbers for the Baoquan power station project.
The 1,200MW pumped-storage power station will produce electricity which will be con-nected to the power grid and will serve the function of peak load, valley filling frequency and phrase regulations as well as standby power for emergency.
THE ALIMAK RAISE CLIMBERS
The two ALIMAK STH-5DD diesel-hydraulic driven Raise Climbers will be used to drive two parallel pressure shafts of 400 metres height in inclinations of 50 degrees. The contract also includes two ALIMAK service and safety climbers of model Alicab-5D as well as installation and training on site. Delivery of the Raise Climbers is scheduled for January 2005.
These two Raise Climbers are the latest in a row delivered to hydropower projects in China. Recent earlier deliveries are for Shanxi Xilongchi, Tongbai, Tian Huang Ping, Ming Tombs and Guangzhou I project. In all, more than 2300 ALIMAK Raise Climbers have been delivered to mines and hydro power projects the world over.
The power station is composed of an upper and a lower reservoirs, water delivery and power generation facilities. The lower reservoir is to be reconstructed from the existing Baoquan reservoir, which is a stone masonry gravity dam. Its crest height will be 107m after reconstruction and the total storage capacity will be 67.5 million m3. The highest water head for power generation is 562 meters.
The power station is located on the Yuhe River, in Huixiang County, Xinxiang City, Henan province, having a straight distance of 80km from Zhengzhou City.
The Yuhe River is a tributary of Weihe River in Haihe river basin. The 82km long Ruhe River covers a drainage area of 672km2. Above the Baoquan dam controls a drainage area of 538.4km2, occupying 86% of the whole river basin.


Locks and Dam No. 52 is located on the Ohio River about 1.5 miles downstream of Brookport, Illinois, at mile 939 below Pittsburgh, Pennsylvania. The locks are located on the Illinois bank of the river. The upper pool above the dam extends for 20.5 miles to Smithland Locks and Dam. Locks and Dam No. 53 is located on the Ohio River approximately 11 miles upstream of Cairo, Illinois. The locks are located on the Illinois side of the river approximately 962 miles downstream from Pittsburgh, Pennsylvania. The upper pool above the dam extends upstream for a distance of 23 miles to Locks and Dam 52.
Modernization of the facilities at Locks and Dam 52 and Locks and Dam 53 were authorized under the provisions of the Rivers and Harbors Act of March 3, 1909. The original structure of 52 was completed in 1928 and 53’s original structure was completed in 1929.
Locks and Dams 52 and 53, in the lower portion of the river, are remnants of the original 1929 river navigation system. A temporary 1200‑foot lock has been built at each project to handle the traffic that moves through the lower portion of the river. These low-cost structures provide an immediate relief to the traffic jam (as much as a three-day wait) at each lock and dam. The temporary 1200-foot lock at Locks and Dam 53 was designed similar to an earlier structure built at Locks and Dam 52. The temporary 1200‑foot lock at Locks and Dam 52 was designed and constructed in just over a year. The structure won a Chief of Engineer’s Award for its many innovative technical features. Locks and Dams 52 and 53 are scheduled for replacement by the Olmsted Locks and Dam project.

South Carolina Electric and Gas (SCE&G) is to begin raising the level of the Lake Murray reservoir behind the Saluda dam in South Carolina, US ahead of schedule.
The work is part of a remedial strategy that saw the construction of a second dam at the site that will secure the reservoir in the face of seismic activity up to the magnitude of the Charleston earthquake, measuring 7.3 on the Richter scale, which struck in 1886.
The level of Lake Murray will now be increased from its current 105m up to the target level of 107m. Once this level is reached, it will be maintained until the last segment of foundation backfilling is completed.
The news was announced by the US Federal Energy Regulatory Commission (FERC), which allowed SCE&G to proceed early with its plans once it saw that the dam was responding well to the construction of the back-up dam. If the dam continues to respond well, refilling at the reservoir will continue to its seasonal level.
The reservoir was first lowered in order to reduce the risks of dam failure during critical stages of construction of the back-up dam.
The programme of work is to be completed by spring 2005.

A two-member team of Geological Survey of India (GSI) has conducted a survey for construction of proposed additional spillway at the left dyke of the Hirakud Dam Project in Odisha, an official said today. The team members - Director of GSI, Jayadeep Mukharjee and scientist of GSI, Ramesh Chandra Munda - visited the site on Tuesday, Superintending engineer of the Hirakud Dam Project, Harmohan Pradhan said. They would prepare the final report on the additional spillway and submit it to the project's Chief Engineer. Later, it would be submitted to the Central Water Commission (CWC), he said. An amount of Rs 350 crore has already been approved by the World Bank for the construction of additional spillway at Hirakud Dam under the Dam Rehabilitation and Improvement Project (DRIP), he said, adding that land acquisition status for the additional spillway was also reviewed recently. Around 311 acres of land, including 157 acres of private tracts, is required to be acquired for construction of the spillway, Executive Engineer of the Hirakud Dam Project, Chinmaya Rout said. The additional spillway was earlier proposed to be constructed at Gandhi hillock, but GSI did not find the rock beneath the soil suitable for the construction there. Subsequently, a new site on the left dyke was identified for the construction of the spillway. Construction of additional spillway is planned to increase the flood water discharge capacity of Hirakud Dam to around 24 lakh cusec, officials said. At present, there are 98 gates to release the flood water from the Hirakud dam. Of the total, 64 are sluice gates and 34 are crest gates. Around 15 lakh cusec water is released through the 98 gates at a time. The additional spillway was proposed after CWC revised flood water release capacity of all major dams.

First Colony Levee Improvement District No. 2 has authorized Jones|Carter (JC) to begin design of the Stormwater Pump Station Expansion. The expansion project will add a 3rd pump to the existing station, with additional pumping capacity of 22,000 gpm. The additional pump will be located in a separate wet well and will be lower than the existing pumps. This will improve the overall performance of the pumps by allowing the District to begin pumping operations earlier and at a higher capacity than the existing system currently allows. The improvements will also allow for the ability to efficiently test the pumps on a regular basis.
Additionally, the project proposes to upgrade the existing generator with a new 450 kW natural gas generator and add an additional 450 kW diesel generator for backup. The electrical controls will be upgraded with the addition of the 3rd pump and will be moved inside the storage building. The outfall from Alcorn Lake to the pump station will be replaced with a larger storm sewer to reduce the time it takes to gravity drain the lake and to provide the capacity necessary to run the pumps. The project is estimated to bid late summer and start construction in Fall 2018. Construction is estimated to be complete prior to the height of hurricane season 2019.

The 531MW Alto Maipo hydroelectric power project involves two run-of-the-river power plants, namely Alfalfal II and Las Lajas that are currently under construction on the Maipo River, in the Cordillera province of Chile.
The project is being developed through a special purpose company Alto Maipo comprising the Chilean subsidiary of AES Corporation, AES Gener (60%), and Antofagasta Minerals (40%).
The construction works on the £866.24m ($1.375bn) project were started in the fourth quarter of 2013 with commissioning expected in the second half of 2021.
At full capacity, the Alto Maipo power project is expected to generate approximately 2,350 Giga-watt hours (GWh) of electricity annually.
Location and site details
The Alto Maipo hydroelectric power project is located in the Andes, on the Maipo River, in the San José de Maipo district, Cordillera province, Chile, approximately 50km south of Santiago.
The project site lies near the load centre of Chile’s power grid. The Alfalfal II plant is situated in the Colorado River sub-basin, downstream of the existing Alfalfal I power plant, while the Las Lajas power plant lies on the southern bank of the Colorado River in the El Sauce sector.
Alto Maipo hydroelectric power project make-up
The Alto Maipo hydroelectric power project consists of the Alfalfal II and the Las Lajas power plants of 264MW and 267MW capacities respectively. Each plant will have an underground powerhouse equipped with two Pelton-type turbines.
The Alfalfal II plant will receive the water flow for power generation through a 600m-high and 2.4m-diameter penstock, while the Las Lajas plant will be transferred water through two 160m-high and 3.7m-diameter penstocks.
The project also involves the construction of 67km of tunnels, four inverted siphons to cross streams, two forebays, and associated facilities, as well as 31km of new access roads, four new bridges, and 17km of 110/220kV power transmission lines.
The surface civil works include the construction of water intake structures, delivery canals, and new bridges over Colorado and the Yeso Rivers.
As the project does not involve dam construction, the majority of the construction works are limited to two underground powerhouses, water abduction systems, and associated infrastructure. A 4.2t Liebherr 53K self-erecting tower crane, along with an 85 EC-B 5b flat-top crane was deployed for the installation activities.

Andritz has won a contract for the rehabilitation and modernization of the entire electro-mechanical equipment, including the inspection and repair of nine penstocks, for the Nurek hydropower plant in the Republic of Tajikistan.
The contract, valued at just over €120 million, was awarded by Barqi Tojik. The refurb project is being funded by the World Bank.
With a current installed capacity of 3000MW, Nurek is the largest hydropower plant in Central Asia and covers more than 70% of the national electrical energy demand.
The objectives of the Nurek Hydropower Rehabilitation Project for Tajikistan are to rehabilitate and restore the generating capacity of nine power generating units at Nurek hydropower plant, improve their efficiency, and enhance the safety of the Nurek dam.
Andritz’s scope of supply comprises comprehensive modernization of the existing nine generating units by supplying and installing new 380MW Francis turbines and generators, including new transformers, as well as the electrical and mechanical auxiliary equipment within the power house. After modernization, the installed capacity of the generating units will be increased by about 12%.
The design of the new units takes account of the plant’s annual storage operations and will, therefore, be suitable for operation with a wide range of heads. Together with the Rogun hydropower plant, which is under construction and located upstream of the Nurek reservoir, this project will optimize water storage management on the Vaksh river cascade, ensuring a significant increase in electrical energy production by the Nurek hydropower station as well as meeting the changing grid demands. The contract also stipulates that environmental conservation measures and water management requirements must be incorporated.

The energy efficiency of the piston pumps is one of the considerable important factors in design and analysis of hydraulic system, especially in the process of real-time tracking of energy dissipation in a variety of loading conditions. The existing methods for obtaining the energy efficiency curve of piston pumps are either time-consuming or inaccurate. In order to quantify the energy efficiency of the piston pumps quickly and accurately, the leakage and friction energy loss caused by the clearances in the sliding pairs are analyzed, and an overall efficiency model was established, which contains two constants to be determined by two test points. The accuracy of the model was verified based on a test rig for a hydraulic pump, and it can be improved by selecting appropriate test points via the method of deviation analysis. The results show that the proposed efficiency models are in good agreement with the experimental results, and the best test points are in the range of 0–25% and 51–75% of the peak pressure of the investigated piston pump.

Main Article Content
The Research studies on filtration shows, over 70 Percentage of hydraulic systems failures are due to contamination or poor liquid conditions. Therefore filters are necessary in modern hydraulic systems to provide specified level of cleanliness, reliability, the hydraulic efficiency and the performance of the filters needs to be ensured the real life working conditions. For efficient operation of any pumping system, appropriate selection of associated pump is highly essential which in turn needs correct estimation of head losses of various elements specials of the pumping system including valves, filters, bends, piping etc. Since electric energy required for pumping reduces with reduction in head loss in pumping system. A need for minimum loss of head across the filters is required in pumping systems. On this background the selection of filter for a certain application is often based not solely on the filtration efficiency and dirt capacity but also low head across the filter.
The paper highlights the improvisations effected in design of Y type filter through research undertaken at CWPRS for achieving percentage reduction in head loss with original design by using CFD simulation and experimentation. The reduction in head loss to such an extent had achieved huge saving in recurring expenditure towards power charges for pumping purpose.

Helping to develop America’s domestic and international energy resources.
From large locks and dams built for the U.S. Army Corps of Engineers to local flood control projects, Lane has the expertise to complete the most challenging types of heavy civil engineering.
The Webuild Group (previously Salini Impregilo Group) has been acknowledged as the worldwide leader, since 2013, in the construction of infrastructure projects in the water segment. The Group has built 257 dams and hydroelectric plants in five different continents, with an installed capacity of more than 37,500 MW of low-cost clean energy, thereby contributing to the sustainable development of entire nations.
The Group is involved in the development of complex hydraulic engineering projects which include the Expansion of the Panama Canal, one of the most important engineering feats of the XXI century, the Grand Ethiopian Renaissance Dam in Ethiopia, which when finished will be Africa’s largest dam, as well as the Lake Mead Intake, a system for collecting and transporting the waters of one of the largest artificial lakes of the United States.


The Board of Managers of the Middle River Snake River Watershed District (now the Middle Snake Tamarac Rivers Watershed District) established the Angus Oslo Site #1 Impoundment in 1982. Primarily a flood control project, Angus-Oslo #1 also provides incidental wildlife benefits. The project included land acquisition, inlet ditches, and construction of the outlet structure. The affected area includes a wetland area totaling approximately 125 acres and approximately 145 acres of cropland. Completed in 1983, the $152,000 project was funded by the Legislative Commission on Minnesota Resources (LCMR), the Red River Watershed Management Board and the Middle River Snake River Watershed District project fund.


- Zimbabwe’s state-owned power utility has announced plans to resume work on the Kariba Dam Rehabilitation Project.
- The Kariba Dam Rehabilitation Project (KDRP) comprises the reshaping of the plunge pool and the refurbishing of the spillway gates.
- The project has been plagued by covid related delays over the last two years and last month, the project was temporarily halted.
The works started in 2017 with the plunge pool reshaping. The USD 294 million project is being funded by the European Union, World Bank, African Development Bank, the government of Sweden and the Zambezi River Authority on behalf of the governments of Zambia and Zimbabwe, through a combination of grants and loans.
The work on the Kariba rehabilitation project will result in even more reduced power generation capacity, and therefore more supply woes for the country. Read more
“Following the Zambezi River Authority’s request to reduce generation levels at the Kariba North and Kariba South power stations, some units at the Kariba South Power Station will be taken out of service daily to allow for completion of critical works on the dam wall, resulting in reduced generation levels and load curtailment,” the Zimbabwe Electricity Supply Authority (ZESA) said on Tuesday.

Halslon reservoir is the main reservoir of the Karahnjukar hydropower project in the Eastern highlands of Iceland currently under construction. The reservoir has storage capacity of 2100 million m3 and generating capacity of approximately 4600 GWh/year. Studies for the Environmental Impact Assessment for the hydropower project showed that sediment will fill up the reservoir in about 500 years based on the present sediment transport rate. The main source of the sediment is Bruarjokull outlet glacier which is a part of the Vatnajokull ice cap. Recent studies of influence of climate warming on Icelandic glaciers show that they will decrease significantly and in some cases completely disappear during the next few hundred years. In this study a glacier melting model for the Bruarjokull outlet glacier is constructed to predict how fast the glacier will decrease as a response to accepted climate warming scenario. The results from the glacier model is then used as an input to sediment transport mass balance model for Halslon reservoir which predicts the influence of the glacier melting on the sedimentation in the reservoir. The modeling shows that instead of the reservoir being completely full of sediment in 500 years, the Halslon reservoir will have at that time about 50-60% of its volume remaining as the sediment yield will decrease as a result of the decreasing glacier size.

The pump is a device used in industrial production, which contains many parts and pump accessories. The main parts of the pump are: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve and so on. Except that the shaft material is high-quality carbon steel, the rest of the main parts are usually made of cast iron, cast steel, stainless steel, and other materials.
Under normal circumstances, in the pump body structure, the pump body and the pump cover together form an impeller working chamber. On the access flange of the pump fitting, there is a tube screw hole for installing the vacuum gauge and pressure gauge. The lower part of the inlet and outlet flanges is equipped with a tapped hole for the water discharge. The static balance test impeller is fixed on the shaft with the sleeve and the bushing nuts on both sides, and its axial position can be adjusted by the sleeve nut.
During the operation of the pump, the axial force of the impeller of the pump fitting is distributed symmetrically by means of its blades so that the influent water is balanced on both sides. The pump bearings are radial ball bearings. The bearings are mounted in the bearing body, installed at both ends of the pump body, and lubricated with butter. If an abnormal sound is found during the operation of the pump, stop immediately and check the cause and take appropriate measures to eliminate it.http://www.dmgcastings.com/


The Lower San Joaquin River Feasibility Study (LSJRFS) aims to reduce the overall flood risk in the Stockton metropolitan area. A high risk of flooding from levee failure threatens the safety of people, property and critical infrastructure throughout the area.
The study area is located along the lower (northern) portion of the San Joaquin River system in California's Central Valley. The San Joaquin River originates on the western slope of the Sierra Nevada and emerges from the foothills at Friant Dam. The river flows west to the Central Valley, where it is joined by the Fresno, Chowchilla, Merced, Tuolumne, Stanislaus and Calaveras rivers and smaller tributaries as it flows north to the Sacramento-San Joaquin Delta.
Study and Project History:
This study was authorized by the Flood Control Act of 1944 and construction initiated in 1956 with various modifications made through the mid-1980’s. The Federally-constructed portion of the project consists of 100 miles of intermittent levees along the San Joaquin River downstream of the Merced River, as well as along Paradise Cut, Old River, Camp Slough, and the lower reaches of the Stanislaus and Tuolumne Rivers. The project also included construction of New Hogan Dam on the Calaveras River, New Melones Dam on the Stanislaus River, and Old Don Pedro Dam on the Tuolumne River. The Chowchilla and Eastside Bypasses were constructed by the State as part of the project. Project levees were designed and built to reduce flood risk in the downstream areas.
Over the 60-year period since those levees were constructed, their estimated level of performance has been reduced by changes in the hydrologic record, settlement, erosion, extensive sediment deposition, and establishment of vegetation between the levees. The project cannot be maintained as originally envisioned due to environmental constraints that did not exist when the project was authorized and constructed.

The Impact of the Uncertain Input Data of Multi-Purpose Reservoir Volumes under Hydrological Extremes
The topic of uncertainties in water management tasks is a very extensive and highly discussed one. It is generally based on the theory that uncertainties comprise epistemic uncertainty and aleatoric uncertainty. This work deals with the comprehensive determination of the functional water volumes of a reservoir during extreme hydrological events under conditions of aleatoric uncertainty described as input data uncertainties. In this case, the input data uncertainties were constructed using the Monte Carlo method and applied to the data employed in the water management solution of the reservoir: (i) average monthly water inflows, (ii) hydrographs, (iii) bathygraphic curves and (iv) water losses by evaporation and dam seepage. To determine the storage volume of the reservoir, a simulation-optimization model of the reservoir was developed, which uses the balance equation of the reservoir to determine its optimal storage volume. For the second hydrological extreme, a simulation model for the transformation of flood discharges was developed, which works on the principle of the first order of the reservoir differential equation. By linking the two models, it is possible to comprehensively determine the functional volumes of the reservoir in terms of input data uncertainties. The practical application of the models was applied to a case study of the Vír reservoir in the Czech Republic, which fulfils the purpose of water storage and flood protection. The obtained results were analyzed in detail to verify whether the reservoir is sufficiently resistant to current hydrological extremes and also to suggest a redistribution of functional volumes of the reservoir under conditions of measurement uncertainty.

Construction projects are underway on both ends of Twisp to install new water lines and sidewalks.
New sidewalks, curbs and gutters have been installed on Twisp Avenue, at the north end of Glover Street, between Highway 20 and Lincoln Street.
The federally funded project will improve pedestrian access through town and to the Twisp park and pool.
“It provides connectivity” for pedestrians through town, said Howard Moss, interim public works director. The $163,000 project is being done by Lloyd Logging Inc. of Twisp.
At the south end of town, crews are replacing 50-year-old water mains with new, larger pipes along Highway 20 between Marble Street and Airport Road.
“The project is replacing substandard diameter water mains from 1948 to current design standards,” Moss said. Six new fire hydrants will also be installed.
When the water project is completed, a second project will immediately get underway to install sidewalks, curbs and drainage along the same section of road, Moss said.
The water project is being done by DJB Construction of Wenatchee through a $363,000 federal rural development loan. It is expected to be completed in about three weeks, Moss said.

Basic structure of centrifugal pump
It consists of six parts: impeller, pump body, pump shaft, bearing, seal ring, stuffing box.
1. The impeller is the core part of the centrifugal pump. It has a high speed and high output. The blades on the impeller play a major role. The impeller must pass the static balance test before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce the frictional loss of water flow. According to its mechanical structure, it can be divided into three types: closed, semi-closed and open. Closed impellers are suitable for conveying clean liquids; semi-closed and open impellers are suitable for conveying suspensions containing solid particles. Such pumps have low efficiency.
2. The pump body is also called the pump casing, which is the main body of the water pump. It plays a supporting and fixing role and is connected with the bracket on which the bearing is installed.
3. The function of the pump shaft is to connect the motor and the motor through a coupling to transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.
4. The sliding bearing is made of transparent oil as lubricant. Add oil to the oil level line. Too much oil will leak out along the pump shaft, too few bearings will overheat and burn out and cause an accident! During the operation of the pump, the temperature of the bearing is up to 85 degrees, and generally runs at about 60 degrees.
5. Sealing ring is also called leakage reducing ring.
6. The stuffing box is mainly composed of packing, water-sealing ring, packing tube, packing gland and water-sealing pipe. The function of the stuffing box is mainly to close the gap between the pump casing and the pump shaft, and to prevent the water in the pump from flowing to the outside and the outside air from entering the pump. Always keep the vacuum inside the pump! When the pump shaft and the filler produce friction to generate heat, it is necessary to hold the water into the water seal ring to cool the filler by the water seal tube! Keep the pump running normally. Therefore, special attention must be paid to the inspection of the stuffing box during the running inspection of the pump! The packing needs to be replaced after about 600 hours of operation.
