The Birkdale Lift Station, Force Main and Emergency Flow Diversion Structure project was completed in September 2013. Freese and Nichols' scope included the study, design and construction phase services for the project. During the bid phase, the project was divided up into two separate contracts. One contract was for the construction of the 20-inch force main and the other contract was for the construction of the 9.8-MGD lift station and HDD bore underneath the Guadalupe River. The project was split to allow local contractors to bid the force main and to prevent general contractor markup on the line work. The City saved almost $200,000 by implementing this innovative bid approach.

The paper describes the methodology employed to control water levels within Yuvacik Dam near Izmit, Turkey. It also provides details of a current study, results of which are expected to improve the operational control of this water supply and flood retention dam. The study includes the application of a hydrological model coupled with atmospheric forecast data; the project is currently active and being carried out by Thames Water International in conjunction with Middle East Technical University and Anadolu University. The study proposes to use of semi-distributed hydrologic modelling coupled with numerical weather prediction and GIS technology. The predicted precipitation and temperature values obtained by the numerical weather prediction model will be used as input to the hydrological model for near-real time runoff estimation to the Yuvacik dam reservoir for better and efficient operation.


1. For gate valve:
Gate valve refers to a valve whose closing part moves in the vertical direction of the channel axis. It is mainly used to cut off the medium on the pipeline, that is, the gate valve is fully opened or fully closed.
In general, gate valve cannot be used to regulate flow. With different material used for the gate valve, it can be applied to low temperature,low pressure pipelines and also can be applied to high temperature and high pressure pipelines.
1.1. the advantage of gate valve:
①. the gate valve has small flow resistance.
②. the gate valve requires less torque for opening and closing.
③. the gate valve can be used on the ring network pipeline where the medium flows in two directions, that is to say, the flow direction of the medium is not restricted.
④. when the gate valve is fully open, the sealing surface is less eroded by the working medium than the globe valve.
⑤. the gate valve has relatively simple body structure, and its manufacturing process is better.
⑥. the face to face length of the gate valve is relatively short.
1.2. the disadvantage of gate valve
①. the gate valve’s external dimensions and opening height are large, so it requires larger space to install.
②. During the gate valve’s opening and closing process, the sealing surface is relatively rubbed, and the friction loss is large, and even when the temperature is high, it is easy to cause scratches.
③. Generally, the gate valves have two sealing surfaces, which makes it difficult to process, grind, and maintain.
④. the gate valve has longer opening and closing time.
2. For check valve:
The check valve is also called cut off valve, one way valve, back-pressure valve, non-return valve. These check valves are automatically opened and closed by force generated by the flow of the medium itself in the pipelines, and they are one kind of automatic valve.
2.1. Where the check valve is used:
The check valve is mainly used in the pipeline system, and its main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container. The check valve may also be used on auxiliary supplying pipe lines system where the pressure may rise above the system pressure.
The check valve mainly includes swing check valve( rotating around the center of the gravity), lift check valve(move along the axis line), wafer butterfly type check valve, ball type check valve, shuttle check valve.

Abstract: The US Department of Agriculture Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Earlier model studies resulted in modifying the design criteria to include a 1:16-exit flare at the downstream end of the structure to return to the downstream channel width. That change resulted in a much longer structure with associated higher construction costs. This study developed a new design criteria for loose riprap drop structures that incorporates recent advances in riprap stability research, numerical backwater codes, and hydraulic model study results. The design method and tools presented herein allow the designer to optimize the size and amount of riprap used in the design.

The Water Authority announced that last weekend the water level in the Kinneret rose from continued flow of rivers and streams, by seven centimeters (2.75 inches). This brings the water level up above the lower red line.
The water level is now 212.99 meters, bringing it to 4.19 meters below its maximum level (the upper red line). The rain that has already fallen will raise the level much more, but everyone hopes and prays for more rain.
There are three water level lines drawn by authorities for the Kinneret: the upper red line which is the highest level it can be allowed to reach before opening the dam to let out water, the lower red line which is a level below which it was always said the water should not fall, and the black line which is a level at which it is said that irreversible damage will happen to the lake ecosystem. The water level has not reached the black line, but for years it has not filled up to the lower red line.


Ball Construction is pleased to report steady progress at the Waste Water Treatment Plant (WWTP) upgrade at 700 Woodward Avenue, in Hamilton, Ontario.
This is a joint venture between Ball and Maple Reinders (deemed Maple Ball JV). Having begun in 2017, the estimated $87 million sub-project is part of the city’s Clean Harbour Program, a series of projects designed to improve the water quality of Hamilton Harbour.
Working in conjunction with the consultants, AECOM, this general contractor/bid spec project involves constructing a new main pumping station (MPS) for the WWTP. Benefits include increased capacity, enhanced conveyance to mitigate system flooding, provide increased system storage and reduce solids buildup during dry weather flows, and an improved maintenance regiment that will allow for half the wet well to be offline for maintenance while the pumping station remains operating.
The new circular building will be 41.97 metres in diameter and approximately 43 metres height, of which 27 metres will be underground. The pumping station will house 12 pumps, each having 700 horsepower and have an overall capacity of 1,700 ML/d (megalitres per day) of waste water.
Phase 1, which involved relocation of the engineering offices and construction of the new site entrance, is now complete.
We are now working through Phase 2, which requires construction and commissioning of the new main pumping station and inlet tunnel. We have recently finished the excavation of the pumping station shaft and we are commencing the concrete works and foundation rock anchors. We’ve also begun tunnel operations for the inlet tunnel that will connect the existing pump station to the future pump station.
Phase 3 will involve abatement of designated substances and demolition of the existing pumping station and has not yet started.
The project’s completion date is estimated to finish in mid-May of 2021.

The water level in Hemavati Reservoir at Gorur near here has been increasing gradually with good rains in the catchment area, forcing the officers of Hemavati Project to issue a warning to people in the downstream to shift to safer places.
The press release, issued by the Hemavati Project Circle, states that the people settled close to the downstream should relocate to the safer places as crest gates of the dam could be opened anytime. As on Wednesday morning, the water level in the reservoir stood at 2,912.5 ft. against the full reservoir level of 2,922 ft. The live storage in the reservoir is 27.28 tmc ft. Last year on this day water available in the reservoir was only 5.67 tmc ft.
The catchment area of the reservoir, spread over Hassan and Chikkamagaluru districts, has received heavy rains since June. The inflow in the last 24 hours was 20,535 cusecs and if it remains so for a couple of more days, the water level would reach the maximum, prompting the officers to open the crest gates.

Description for Koysha Hydropower (Ethiopia)
Koysha (2’160 MW, under construction) is the fourth hydropower plant of Omo/Gibe river cascade in Ethiopia, comprising Gilgel Gibe (200 MW), Gibe II (420 MW) and Gibe III (1’870 MW), all currently in operation.
Koysha is a step forward in the development of the entire hydropower potential of the Omo river and represents a realization of the large-scale vision started more than 25 years ago with the design of Gilgel Gibe hydroelectric power plant. It testifies our long-term commitment for the progress of Ethiopia’s energy sector.
The project includes several outstanding examples of value engineering and design optimization, carried out by SP throughout the entire design and construction period of the hydroelectric power plant.
The layout includes an RCC gravity dam, approximately 180 m high, that creates a large reservoir of about 6’500 Mm3.
Floods are discharged by means of a gated spillway located on a saddle at the left side of the RCC dam: a large channel with a flip bucket designed for releasing a flow of about 13’100 m3/s in a plunge pool adjacent to the river, downstream of the powerhouse.
The dam is crossed by three steel penstocks feeding an open-air powerhouse, one of the intakes is lowered to allow early generation using the first two units during the first impounding.
The project includes two 6 m diameter middle level outlets embedded in the dam body allowing to control the reservoir level during the first impounding, release artificial/ecological flows and lowering the reservoir level for inspection/maintenance needs.
The river diversion layout includes two concrete culverts on the right side of the river, aimed to divert the river during the dam construction and designed to discharge up to 3’000 m3/s, and an upstream composite RCC/rockfill cofferdam.
Both the river diversion layout and the energy-generation operating rules of Koysha have been optimized taking advantage of the large flow regulation capacity of the upstream Gibe III project.
Tandem operations of the two projects allow to maximize energy generation and provide great flexibility guaranteeing power supply during both dry season and peak-demand period.
The power house is located on the left side of the river, housing eight Francis turbines generating 2’160 MW, together with erection bays and control building. Step-up transformers are located behind the powerhouse. Each unit is connected to three single-phase 400 kV transformers, for a total of 24 transformers that are linked through overhead lines to the 400kV Switchyard.
- RCC Gravity Dam ( H = 170 m, crest L = 990 m )
- U/S RCC & Rockfill Cofferdam ( H = 42 m, L = 330 m )

Lower Mattagami River Project
The Lower Mattagami River Project is an investment into clean, renewable energy. It was the largest hydroelectric power generation initiative in nearly 40 years in Northern Ontario. Ontario Power Generation selected Kiewit-Alarie Partnership to design and build the project.
This project retired the old 52-megawatt Smoky Falls Generating Station and constructed a new 271-megawatt station immediately adjacent to the existing plant. In addition, a new generating unit was added to three other power generating stations along the Mattagami River: Little Long, Kipling and Harmon.
The project required the excavation of 650,000 cubic meters of overburden and over 700,000 cubic meters of rock, as well as the placement of over 190,000 cubic meters of concrete over five years.
Foundations work included a 5,050-square-foot cut-off wall to support construction to repair and replace four hydroelectric generating stations.
The project increased Ontario’s energy generation capacity by over 440 megawatts, enough electricity to power up to 440,000 additional homes.


The channel has experienced lining failures and overtopping during recent years. The proposed project will increase channel conveyance capacity for a 100-year storm event. To accomplish this, the existing trapezoidal channel will be replaced with a vertical wall rectangular channel that will be constructed within the existing right-of-way.
FEMA through their Hazard Mitigation Grant Program (HMGP) has committed $3.12 million dollars towards the design and construction of the improvements. The balance of the estimated $8.8 million cost for construction is to be funded by the Orange County Flood Control District (OCFCD).
Making Orange County a safe, healthy, and fulfilling place to live, work, and play, today and for generations to come, by providing outstanding, cost-effective regional public services.

The butterfly check valve is very simple and its structure is very short compared to other check valves. The butterfly check valve is also called butterfly check valve. The connection method is a pinch type. The valve plate is two semi-circular discs. The two discs are connected by a valve stem and are forced to reset with a spring.
The operating principle of butterfly check valve is: when the medium flows through the valve body channel, the medium pressure is greater than the force of the spring.When the medium stops flowing, the two butterfly plates are forced by the spring to reset and the valve closes, preventing the medium from backflow.
The butterfly check valve is also called the double-clip check valve for the clip. The sealing surface of the butterfly check valve can be body-welded wear-resistant material or lining rubber. The use range is wide and the seal is reliable. Butterfly check valves are automatic valves that do not require manual operation. This kind of valve is usually used in pure pipelines, in addition to industrial, environmental protection, water treatment, high-rise buildings in the field of water supply and drainage pipelines, to prevent the back flow of the media.

Štěchovice Reservoir (in Czech Vodní nádrž Štěchovice) is a dam on Vltava River built from 1937 to 1945 as the second stage of the Vltava Cascade. The dam is named after nearby village Štěchovice.
The construction started before World War 2 and because of the need for electricity resources were allocated for the project in spite of general shortage. The power station was put in action in 1943. The reservoir had flooded St John's Rapids (Svatojánské proudy), the most dangerous but romantic part of Vltava.
The main role of the reservoir is to balance the water runoff from peak-load power station at Slapy Dam and to propel two Kaplan turbines with total installed power 2 x 11.25 MW (Štěchovice I). A lock (20.1 m difference between water levels, length 118 m) handles ships with displacement up to 1,000 tons.
The reservoir is also used by the pumped-storage hydroelectric plant Štěchovice II whose upper reservoir was created on the top of hill Homole. The plant was set in operation in 1947 and closed in 1991 due to obsolescence. From 1992 to 1996 a new hydroelectric plant using the reservoirs was built. This plant uses reverse Francis turbine with power 45 MW.
During 2002 floods the turbines of both power plants were severely damaged. After overhaul the plants were put back in production in 2004 and 2005 respectively.
Technical parameters of the reservoir
height of the dam: 22.5 m
length of the dam arch: 124 m
held back water stretches 9.4 km
reservoir area: 95.7 hectares
water capacity: 11.2 million m³

Reconstruction of the Measuring and Test Equipment (MTE) for the Maina Hydraulic Power System
Bancomzvjazok’s specialists have performed the analysis of the initial data and developed the design documentation for automation of the measuring and test equipment of the Maina Hydraulic Power System (Russia) as part of a joint project with Lenhydroproject, JSC—“The Integrated Reconstruction of the Maina Hydraulic Power System” in the shortest time. Our project includes key issues on MTE automation of earth dams and concrete structures. The customer of the project—Lenhydroproject, JSC—is one of the largest design and survey institutes in Russia, occupies one of the leading positions in the field of design of hydroelectric and water management facilities and performs a full range of design and author supervision services for the construction of hydraulic structures in areas with particularly complex geological-climatic conditions. The Maina Hydraulic Power System, located in the south of the Republic of Khakassia, in the head of the Yenisei River, was built at the end of the last century. The Sayano-Shushenskaya Dam and Maina Hydraulic Power System is a single hydropower complex. Its main purpose is to smooth fluctuations in the river level in tail water, create satisfactory conditions for water users, and generate additional electricity. The Maina Hydraulic Power System includes the right bank, channel, and left-bank earth dams, a HEP building with three hydraulic units with rotary-bladed turbines, and a concrete spillway dam with five spans of 25m each. The installed capacity of the Maina HEP is 321 thousand kW; the annual power generation is 1.7 billion kWh. The designed measuring and test equipment takes into account a wide range of factors affecting the reliability and safety of the Maina HEP facilities. In order to automate and increase the promptness of the collection of readings, the measuring devices existing at the station will be equipped with automatic sensors. According to the project, the hydraulic levels will be equipped with a geodetic micrometer altimeter in order to control the vertical movement of reinforced concrete blocks of structures, piezometers on earth structures—with pressure sensors to control the depression curve. It is planned to equip the head of the water structures with pressure sensors and a string of thermometers to measure the water level and control the filtration horizons through concrete structures. Multiplexers and local data concentrators installed will perform interrogations of collateral equipment, automation sensors and further transfer of measurements to the central processing unit. In addition, Bancomzvjazok JSC was faced with the task of designing the head of a piezometer located under the roadway along the dam crest. The difficulty was that this device should be used in an unusual and uncharacteristic area. The company's specialists have developed and proposed a unique design of the head of a piezometer that will allow taking large point loads without damaging it. For each site, the type of the cable routes laying and the location of secondary equipment have been considered.

Benbrook Lake (also known as Benbrook Reservoir) is a reservoir on the Clear Fork of the Trinity River in Tarrant County, Texas, USA. The lake is located approximately 10 miles (16km) southwest of the center of Fort Worth, where the Clear Fork and the West Fork of the Trinity River join. The lake is impounded by the Benbrook Dam. The lake and dam are owned and operated by the U.S. Army Corps of Engineers, Fort Worth District.
Significant flooding on the Trinity River during May 1908, April 1922 and September 1936, was a primary cause for the development of Corps of Engineers flood control projects in North Texas.
Benbrook Dam and Lake were built by the Galveston District of the Corps of Engineers. During the decade of active civil works construction following World War II, the U.S. Congress provided for the construction of Benbrook Lake, Grapevine Lake, Lavon Lake and Ray Roberts Lake as well as modifications to the existing Garza Dam for the construction of Lewisville Lake. The River & Harbors Act of 1945 authorized these projects for the purposes of both flood control and navigation. These lakes and others, along with an extensive floodway system of levees, are operated in a coordinated manner to minimize flooding along the Trinity River floodplain corridor in the Dallas/Fort Worth Metroplex.

Responsible authority needs to pay attention to debris which has been accumulating in Umzingwane River since the onset of the rain season.
The river is a major left-bank tributary of the Limpopo River in the country.
It rises near Fort Usher, Matobo District, south of Bulawayo and flows into the Limpopo River near Beitbridge, downstream of the mouth of the Shashe River and upstream of the mouth of the Bubye River.
The Mzingwane River is an ephemeral river with flow generally restricted to the months when rain takes place (November to March), with most flow recorded between December and February, except where it has been modified by dam operations.
The river contributes 9.3% of the mean annual runoff of the Limpopo Basin, making it the third largest tributary to the Limpopo basin.
Major tributaries of the Mzingwane River include the Insiza, Inyankuni, Ncema, Umchabezi (not to be confused with Mtshabezi) and Mtetengwe Rivers.
The lower Mzingwane River is a sand filled channel, with extensive alluvial aquifers in the river channel and below the alluvial plains.
Currently, some of these aquifers are being used to provide water for domestic use, livestock watering and dip tanks, commercial irrigation and market gardening

In order to study the discharge capacity of Hongze Lake in the middle and lower reaches of Huaihe River during medium and small floods, a one-dimensional and two-dimensional coupling hydrodynamic model was established for the Sanhezha section from Bengbu of Huaihe River to the outlet of Hongze Lake. The impact of key river reaches cutting beach on discharge capacity under middle and low water levels of Hongze Lake and the flood discharge process in watershed before and after cutting beach were simulated and analyzed. The results show that under the five-year flood process, the water level of Bengbu, Linhuaiguan, Xiangmiao, Fushan and Hongshantou hydrologic stations in the main stream of Huaihe River decreased by 0.02.m, 0.07.m, 0.21.m, 0.55.m and 0.70.m, respectively after cutting beach during the flood peak period, and the floodplain time decreased by 1 day, 4 days, 9 days, 9 days and 17 days, respectively. The maximum water level of Sanhezha Station in Hongze Lake was 13.33.m, which was 0.07.m higher than that before cutting beach. The discharge volume corresponding to the lake was 8.300.m3/s, which was 800.m3/s higher than that before cutting beach and the discharge capacity increased by 11%.

Infracon, Eiffage win $104.6M bridge contract tied to B.C.’s Site C dam project
The B.C. Ministry of Transportation and Infrastructure has awarded a major bridge and highway realignment project to a joint venture led by French contractor Eiffage and Vancouver-based Infracon.
The $104.6 million contract covers a new bridge on Highway 29 over Halfway River near Attachie, B.C. — several dozen kilometres west of Fort St. John. The Eiffage-Infracon Halfway River Joint Venture will be responsible for the construction of a new one-kilometre bridge about 500 metres from the current structure and building a new two-lane 3.7-kilometre connection.
Halfway River flows into the Peace River near Attachie and the work is tied to the multibillion-dollar Site C dam project that’s currently under construction just downstream. Once the dam is complete, filling the reservoir will lead the Peace River to swell to approximately two to three times its current size, flooding parts of Hwy. 29’s route.
The new contract is one aspect of the planned mitigation effort. Another 30 kilometres of highway and four additional bridge will also need to be replaced.
Construction on the Halfway River bridge project and related highway realignment are scheduled to get underway this winter. Work is expected to run until fall 2022.


Ukai dam authorities on their toes due to low pressure in the upper catchmentMelvyn Thomas | TNN | Updated: Oct 5, 2013, 13:37 IST
The Met department official said that the low pressure area over south Madhya Pradesh and neighbourhood now lay over central parts of Madhya Pradesh and neighbourhood. The low pressure is associated with cyclonic circulation, which extends upto 3.6 kilometers.
Authorites at the Ukai reservoir said that the water level is at 343.32 feet and the inflow into the dam is 22148 cusecs and the outflow is 22148 cusecs till 4:00 pm.
Around 16 upper catchment areas of Ukai received around 250 mm rains till 3:00 pm on Friday.
Till Friday afternoon, Tiska recorded 49 mm, Lakhpur recorded 72.40 mm, Chikaldhara 10.20 mm, Gopalkheda 40.60 mm and Yerli 46 mm.
"There is low pressure on central Madhya Pradesh. The Hathnoor dam is releasing 10000 cusecs. We are keeping a close watch on the rain pattern, but there is nothing to worry about' said PS Dave, engineer on duty at Ukai dam.


Poor control of the steam generator water level is the main cause of unplanned reactor shutdowns in nuclear power plants. Particularly, at low power levels, it is a difficult task to control the water level due to the shrink and swell phenomena and the unreliable flow measurements. In this paper, a model free adaptive control (MFAC) strategy is proposed, in which the MFAC is used in the primary control loop and the PID controller is adopted in the secondary loop. The simulation results show that, compared with the cascade PID control, the proposed control method has better stability, adaptability, and robustness. Moreover, it is suitable for industrial applications due to its simple structure and easy implement.

ASSESSING THE PERFORMANCE OF BROOKVILLE FLOOD CONTROL DAM
thesisposted on 2019-01-16, 15:08 authored by Mingda LuMingda Lu
In this study, the performance of a flood control reservoir called Brookville Reservoir located in the East fork of the Whitewater River Basin, was analyzed using historic and futuristic data. For that purpose, USEPA HSPF software was used to develop the rainfall runoff modelling of the entire Whitewater River Basin up to Brookville, Indiana. Using uncontrolled flow data, the model was calibrated using 35 years of data and validated using 5 years by evaluating the goodness-offit with R2, RMSE, and NSE. Using historic data, the historic performances were accessed initially.
Using downscaled daily precipitation data obtained from. GCM for the considered region, flows were generated using the calibrated HSPF model. A reservoir operation model was built using the present operating policies. By appending the reservoir simulation model with HSPF model results, performance of the reservoir was assessed for the future conditions.

The Luhri Stage-I hydroelectric project is a 210MW run-of-the-river hydropower project being developed by Satluj Jal Vidyut Nigam (SJVN), a joint venture between the governments of India and Himachal Pradesh state.
It is part of the Luhri hydroelectric project (HEP), which is being implemented in three stages on the Satluj River, in the north Indian state of Himachal Pradesh. The remaining two stages include the 172MW Luhri Stage-II and 382MW Sunni Dam HEP.
Luhri Stage-I is expected to generate up to 758.2 million units of electricity a year, at a levelised tariff of $0.05 (Rs4.24) per unit.
It is estimated to provide free power worth approximately Rs11.4bn ($153m) to Himachal Pradesh during its 40-year life cycle. The families affected by the construction of the project will receive 100 units of free power monthly for ten years.
The foundation stone for the project was laid by the prevailing Prime Minister of India, Narendra Modi, in December 2021. Commissioning of the power plant is expected by April 2026.
The investment required for the Luhri Stage-I project was estimated at $253.7m. The project is expected to generate about 2,000 direct and indirect jobs during the construction phase.
The Luhri Stage-I hydroelectric project is being developed on the Satluj river, near the village of Nirath, in the Shimla and Kullu districts of Himachal Pradesh.
The site is accessible from the national highway (NH) 05.
Luhri Stage-I development background
SJVN and the Government of Himachal Pradesh signed an agreement to execute the project in October 2008. The Government of India approved the investment to undertake pre-construction activities in February 2018.
The project received environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEFCC) in March 2020.
Dam and reservoir details
Luhri Stage-I includes the construction of an 80m-high concrete gravity dam, which will stand 49m tall above the riverbed. It will create a 6km-long reservoir that will occupy 100.23ha.
The upper-level spillway of the dam will be ogee type, featuring open crest overflow with a single flap gate, while the lower-level spillway will be sluice type, with six radial gates.
Luhri Stage-I plant make-up
The powerhouse will be built on the surface, at the dam toe, on the right side of the riverbank. It will comprise two main power units of 80MW capacity each and two 25MW auxiliary power units. All four units of the plant will be equipped with Kaplan turbines and generators.
The main units will receive the water flow through two 6.8m-diameter penstocks measuring 84.14m and 80.48m in length. The penstocks for the two auxiliary units will have a diameter of 4m and measure 95.86m and 99.82m long.
The main and auxiliary power units will have two separate intake structures, each with fixed wheel type intake gates. The main intake will be semi-circular shaped, with inclined trash racks, while the auxiliary intake will be a straight one, with vertical trash racks.
The tailrace system will comprise a 90m-long, upward sloping, concrete-lined channel, downstream of the powerhouse, along with another 30m-long and 45m-wide channel to release water back into the Satluj River.
The Cabinet Committee on Economic Affairs (CCEA) of the Government of India approved an investment proposal of Rs18.1bn ($242.9m) for the project in November 2020. The Government of India also provided grants worth Rs661.9m ($8.8m) to fund the enabling infrastructure for the project.
The project achieved financial closure in March 2022. The State Bank of India reached a loan agreement for Rs15.37bn ($202.93m).
Global industrial equipment supplier Voith Hydro was contracted for electro-mechanical works for the project in August 2021.
The contract for the civil and hydro-mechanical works was awarded to Luhri Hydro Power Consortium, comprising Patel Engineering and HES Infra, in the same month. The scope of the five-year contract includes design and engineering services, in addition to civil and hydro-mechanical works.


Dartmouth release to increase
The Murray-Darling Basin Authority (MDBA) has announced that releases from Dartmouth Dam will increase from tomorrow.
Dam capacity is currently at 99 per cent, with releases through the high level outlet will enable further hydro-electric power generation. The MDBA has also announced it expects there to be significant environmental benefits for the Mitta Mitta River.
Initially, the flow at Colemans will be 1,000 ML/day from 25 October, increasing to 3,000 ML/day on 30 October. The flow will then be gradually reduced during the remainder of the week, to about 2,000 ML/day on 4 November.
The rate of rise in the river level at Colemans could be up to 150 mm/hr, with the maximum rate of fall being 30 mm/hr.
In the next few weeks, releases are planned to maintain the water level in Lake Dartmouth at about 485.4 m AHD (60 cm [40,000 ML] below full supply level) which will reduce the likelihood of flows passing over the spillway. Therefore, in the foreseeable future, the flow at Colemans is likely to remain in the range of 500–4,000 ML/day, depending on inflows to the lake.

Drivers will still be able to enter and exit Scenic Drive by detouring around the closure on Louisville Avenue. The $3.9 million project will reduce flooding in Central El Paso.
The project will increase the capacity of nearby ponds and add piping that keeps water off the streets by directing stormwater into the dam.
Additionally, the project will improve service in the area by replacing water and wastewater lines.
