Selected Project Experience
Mahe Island, Seychelles
The La Gogue Dam was a homogeneous earth fill dam with a maximum height of 35 m from the excavated foundation level and a length of 152 m at the crest. The La Gouge Dam is one of the main water supply reservoirs for north east Mahe.
GIBB maximised the storage capacity of the reservoir by identifying and comparing the cost, technical engineering analysis, resources availability (including transfers) and the availability of construction material. The latter made a priority of maximising the storage capacity of the reservoir.
Roads Eden Island Development Company
This project is unique: the island on which the housing development was constructed is man-made. This was done through the construction of a bund wall which was infilled with coral material from the sea and allowed 5 years to settle, after which vegetation was added.
A bridge was constructed to link Eden Island with Mahe Island. GIBB’s specific task for the Eden Island Project was to assist the client with a high income residential development on Eden Island.
Responsibilities included design of all civil infrastructure including roads, water, sewer and stormwater reticulation for the project.

The earliest hydro electric power station in Uttarakhand was installed at Gailogi for supply of power to Mussoorie town as early as in 1914. A beginning was made in this regard in the 1st decade of 20th Century with the installation of a 450 KW power station at Bahadrabad on Upper Ganga canal exclusively for the supply of power for the construction of Bhimgoda headwork of the canal system at Hardwar. A Hydroelectric survey of Ganga Valley was carried out and a report was submitted by Lyle in 1922. Regular program for utilization of a number of falls on the Ganga canal to generate electric power for Irrigation pumping and electrification of towns fructified later with the commissioning of Pathari power house with 3 units of 6.8 MW each in 1955-56. Uttarakhand can thus, be truly considered as one of the pioneer in the country in utilization of low head canal falls for hydro power generations.
In the early years after independence the country was faced with severe food shortage, therefore, emphasis was given on execution of river valley projects for Irrigation and power for development. An important power project Yamuna stage I was taken up in Dehradun District, which was a run-of-the river power scheme on river Yamuna having two powerhouses at Dhakrani (33.75 MW) and Dhalipur (51 MW). It was followed by Yamuna stage II, part I & part II having installed capacity of 360 MW and Yamuna stage IV, part I & part II totaling installed capacity of 102 MW, in river Yamuna. Similarly Maneri Bhalli stage I having installed capacity of 90 MW and Chilla hydro electric power project with installed capacity of 144 MW on river Ganga were commissioned in 1985. Another landmark was construction of Kalagarh dam on river Ram Ganga by 1976 which was storage project having installed capacity of 198 MW.
Lakhwar Vyasi project on river Yamuna having proposed capacity of 420 MW is held up due to paucity of funds and practically no work is going on the projects for the last 10 years. It is remarkable to note that 60% work on the project had been completed when the construction on the project was brought to a grinding halt. Similarly Vishnu Prayag hydro electric project having proposed capacity of 402 MW and Srinagar hydro electric power project with proposed capacity of 330 MW remained suspended on some account of financial crisis for a very long time. Ultimately these projects were assigned to the private sector but the progress on Vishnu Prayag project was very slow and Srinagar project is yet to start. Another important project on river Bhagirathi known as Tehri Dam project (2400 MW) was also held up for want of funds and ultimately it was handed over to Tehri Hydro Electric Power Corporation, which is a joint venture of Govt. of India and Govt. of U.P. It is likely that the 1st phase of 1000 MW installed capacity may be commissioned very soon. Rehabilitation works of Tehri Damp Project are being carried out by Uttarakhand Irrigation Deptt.

For Trapezoidal weirs most of the proposed discharge coefficient relationships have been obtained experimentally. Also, some theoretical relationships have been proposed based on ignoring the streamline curvature and considering the hydrostatic pressure distribution. In this paper, a numerical model was developed for recently proposed Boussinesq type equations which incorporated the streamline curvature with considering the non-hydrostatic pressure distribution for unsteady flow conditions. The model was employed to determine the discharge coefficient of trapezoidal broad crested weir, the results of which were compared with the compiled experimental data and with available relations. The results showed that the discharge coefficient computed by Level 4 equation, had presented higher accuracy in comparison with the experimental relation for the tested crest weirs. Also modeling these equations was easier compared to the three-dimensional models. These equations could be incorporated with the available one-dimensional of models to produce rating curves and to design water measurement structures for a continuous flume invert.


Site C Clean Energy Project, Design Overview
December 14, 2020
This paper provides an overview of the design of the Site C Clean Energy Project. The Project is an 1100 MW hydroelectric generating facility under construction on the Peace River near Fort St. John, British Columbia, Canada. The Project layout is strongly influenced by the geological and hydraulic requirements at the site. On the left (north) abutment the project includes a large excavation for slope stabilisation as well as two diversion tunnels, one of which will be converted with the construction of orifices and later used for reservoir filling. A 60 m high earthfill dam spans the main river channel, and which abuts concrete structures on the right (south) abutment. The project spillway and power intakes for a six unit powerhouse are fed by a large approach channel on the right abutment. The spillway includes a two-stage stilling basin with surface radial gates and vertical lift low level gates, as well as a free crest spillway. The configuration of the site includes an inclined “RCC buttress” supporting the headworks structures, powerhouse and spillway structures. The project also includes an instrumentation program with an initial focus on capturing rebound and movement resulting from project excavations, and a long-term purpose of monitoring during operation.

Marlow Vertical In-Line Self-Priming Centrifugal Pumps for Petroleum’s and Solvents
Pump: Heavy-duty cast iron construction, with 2" NPT female threaded in-line suction and discharge ports. This compact, vertical design is self-supporting and requires a minimum of floor space. The self-priming feature allows the pump to be mounted above the liquid and suction lifts of 10' to 20' can be achieved, depending on the liquid and the pump model. Diffuser priming eliminates the need for a check valve and reduces radial loads insuring longer bearing life. These pumps are sealed by a self-lubricating, Viton mechanical shaft seal. When used on a suction lift any leakage that may occur will be down into the pump rather than up the motor shaft as the seal is on the suction side of the impeller.
Motor: Single phase motors are 60 cycles, 115/230 volt, except 2 HP explosion proof motors which are 230 volt only. Three phase motors are 60 cycles, 230/460 volt and all are 3450 RPM motors. All explosion proof motors are Class I, Group D, Code: T3B.
Optional Mounting: All models fit the Marlow Pumps lightweight, two wheel chassis.
Optional Seal: Kalrez mechanical seals are available.

MAZAR-I-SHARIF (Pajhwok): Work on the construction of Qush Tepa Canal in northern Balkh province has been accelerated and the mega project is expected to be completed before the stipulated time.
The canal — 280 kilometers long and 100 meters wide — will irrigate 500,000 hectares of land in Balkh, Jawzjan and Faryab provinces.
The 60 billion afs project is being executed by the Afghanistan National Development Company and the entire fund for the project is provided from the national revenue.
Local officials in Balkh province say work on the project was started from the Qush Tepa area and completed till Dawlatabad district. Forty-two kilometers of the project has been constructed.
Mawlavi Abdul Hakeem Hikmat, head of the Northern River Zone, said 120 private companies and around 2,300 people were involved in the construction of the canal.
He said the canal has the capacity of carrying 650 cubic meters water in one second and it would resolve the water shortage issue in Balkh, Jawzjan and Fayab provinces.
Eng. FaridAzeem, provincial in charge of the project, said the Qush Tepa Canal project was of vital importance for Afghanistan and said the country would become self-reliant in terms of agriculture products once the project was completed.
Balkh Governor Qudratullah Abu Hamza said work on the construction of Qush Tepa Canal was underway, adding that the project would be completed before its scheduled date.
Work on the project was launched in the beginning of the current solar year.


The scheme is designed to ease pressure on environmentally sensitive local water sources in West Cumbria, and provide a secure, long-term supply for the area.
It will also involve the construction of new water treatment works, two service reservoirs and a new pumping station.
The £300m project is broken up into several work packages which have seen several firms involved already in the design process under early contractor involvement deals.
A joint venture between Northern Irish contractor Farrans and Atkins drew up detailed plans for a large 13km pipeline from Thirlmere reservoir in the Lake District to Bridekirk.
Its route from the reservoir will loosely follow the direction of A591 northwards through Keswick, passing east of Bassenthwaite, before turning due west towards Williamsgate.
From Williamsgate treatment works a new treated water trunk main will deliver water to Summergrove service reservoir near Whitehaven.
J Murphy & Sons previously signed a £1.3m design contract covering its early involvement in this section of the project.
Full works packages are out to tender with contract awards expected shortly.
In total, five existing water treatment works will also be decommissioned once the new pipeline is commissioned. These will be at Ennerdale, Cornhow, Quarry Hill, Buttermere and Thirlmere.
United Utilities aims to start construction of the major four and a half year project in March 2017.

Curved Blade Radial Flow Turbine (CBT)
An original impeller design, the Curved Blade Turbine impeller (CBT) facilitates batch solid suspension applications where the need to remove all solids from the tank during a draining phase is imperative, and axial flow turbines mix the bulk of the tank until the liquid level falls below the lowest axial turbine. To mix the lower portion of the tank, the shaft can be extended to the bottom of the tank and a smaller radial flow CBT can be installed called a tickler turbine. This impeller continues to mix the remaining volume until draining completes. The swept back blade profile also permits start-up in settled bed as flat blade profiles are more likely to yield.
Heat transfer, low liquid level solid suspension. Flow velocity sensitive applications needing radial flow to break up plug flow.

The Korea Water Resources Corporation (K-water) has started the construction of a hydroelectric dam in Georgia. The US$870 million hydroelectric power plant will be built on the Nenskra River in the northwestern part of the country. The power plant, which is planned to be completed by November 2020, when operational, will generate 280 MW of electricity. The amount is expected to meet the electric consumption needs of 580,000 people. All the power will be supplied to Georgia, which has been suffering from a chronic shortage of electricity during winters because of soaring heating demands and it has been buying electricity at higher prices from Turkey and other neighbouring countries. K-Water signed a build-operatetransfer contract with the Georgian government, which will see the company operate the plant for 36 years and then transfer its ownership to Georgia.

The tubular pumping system on dual-directional operation is used extensively for drainage and feedwater pumping stations of the cities and towns. The performance of the dual-directional operation of pumping systems is different with that of simple-way operation. The article described the three-dimensional fluid flow and the predicted performance of the numerical investigation inside a tubular pumping station on dual-directional operation, based on the Reynolds time-averaged Navier-Stokes equations and the realizable k-ε turbulent flow model, applied the law-of-wall and sliding mesh technique, and comparing with the experiment data. The main phenomena existing in pressure contours, velocity contours, velocity vectors and flow lines is showed. The disturbance of fluid flow from the pump outlet to pumping station channel is researched. The axial-whirling flow, circulation-vortex flow is discovered inside discharge diffuser of tubular pumping station on feed-directional operation. The axial-whirling flow is strengthened as a result of diffuse flow. The circulation-vortex flow of the impeller outlet is enhanced in the radius and reduced in the middle of discharge diffuser without guide vanes. There is more loss of head in discharge diffuser of the channel, comparing with that of the suction reducer. It was a close predicted performance of numerical simulation with that of the experiment in the best efficiency point. There was a more difference between the predicted performances with that of the experiment data on the feedwater-directional operation, comparing that of the drainagewater -directional operation.

The project is a continuation of measures to reduce the energy consumption of water supply networks while at the same time reducing water losses. The costs of water supply will hereby be reduced and quality of life for many people will be improved through the increased water supply security.
The present initiative involves increasing the energy efficiency of the pumping stations by correctly dimensioning and replacing or renewing plant components and supply lines from pumping stations with a pumping capacity between 100 and 500 m³/h.
In addition, there are plans to restructure and renew the water network in the Balqa Governorate supply area, serving an area of approx. 1,100 km² with 80,000 consumers. Priority will be given to the municipality Al-Salt, covering 420 km² and having 32,000 consumers.


Baihetan Hydroelectric Power Station Project
The Baihetan hydroelectric power station is located just upstream of the Yangtze River on the Jisha River in Yunnan province. The 18.8 billion-cubic-meter storage capacity and 12,000 megawatts of installed capacity make it only slightly smaller than the Three Gorges hydroelectric power station. Along with the Three Gorges project, Baihetan is part of a strategic initiative to meet China’s growing demand for power by building cascading power stations on the Yangtze River.
To assure the success of the Baihetan hydroelectric power station, ECIDI initiated a one-year pilot project – the Longkaikou hydroelectric power station with an installed capacity of 1,800 megawatts – which demonstrated the advantage 3D design solutions provided. ECIDI used 3D modeling and ProjectWise for the Baihetan project and drafted the 3D design technical standard to standardize design, including seed file, font, level, workspace, template, ProjectWise structure, and authority.
Using Bentley solutions, ECIDI completed the milestone design and corresponding drawings, power plant and diversion works comparisons, dam position comparisons, complex underground cavern groups design, dam parametric design, complex cut-and-fill design, and integration of 3D geological and design information. Bentley products greatly enhanced efficiency, which allowed more time to optimize the design.

The Moroccan government has signed a contract with Société Nouvelle Travaux Maroc (SNTM), a public works company based in Kenitra, Morocco, for the construction of a 7.8-kilometre drinking water pipeline in Casablanca.
This comes barely a month after the authorities completed the construction and commissioning of a 7.2 km long pipeline between the north of Casablanca and the Mediouna reservoir.
The two lines are implemented as a part of the project to transfer water from the Sidi Mohammed Ben Abdellah dam which is located some 20 km from the Moroccan capital Rabat.
Scope of the project for the construction of the 7.8km drinking water pipeline in Casablanca
Reportedly, as part of the project for the construction of the 7.8km drinking water pipeline in Casablanca, SNTM will carry out the start tapping on the arrival of the 2,000 diameter interconnection pipe at the level of the metering structure in Mediouna, a town and municipality in Médiouna Province of the Casablanca-Settat region.
This will be done with a 1,600 diameter pipe connecting the arrival of the interconnection pipe to the entrance of the Bouskoura reservoir. The works will lead to the connection of the Bouskoura reservoir to its existing 1,200 diameter inlet pipe, upstream of the metering system.
The public works company will also carry out the construction of regulation and protection works and equipment, as well as main road crossings by trenching or sinking, etc.
Expectations for the project
The project for the construction of the 7.8km drinking water pipeline in Casablanca is expected to increase the capacity of a pumping station in Casablanca from 2.5 m3 per second to 4 m3 per second, in addition to the utilization of the surplus water available at the Sidi Mohammed Ben Abdellah dam and subsequently enhance the water supply in the Noth African city, which is currently experiencing drought.
The Oum Er Rbiaâ basin, Al Massira, and other dams’ reserves have all been significantly reduced as a result of this situation. Benguerir, Marrakech, Safi, Youssoufia, Sidi Bennour, El Jadida, Settat, and Berrechid are among the cities and towns affected.


Hydraulic Single Acting Gate Valve (Model M)
FAIL CLOSED OPERATION
The SSV valve with a SAFOCO actuator is normally supplied in the fail-closed configuration. Hydraulic actuator supply pressure drives the valves reverse ported gate down and holds it in the open position under normal operating conditions. In the event of an abnormal condition, the actuator supply pressure is released or bled off by quick exhaust mechanisms, allowing the valve to close by body pressure acting on the bonnet stem diameter and spring force. Restoring of Hydraulic Actuator supply pressure automatically reopens the valve.
When required, the valve can be configured with a fail open gate design for a vent or blow-down system.

The PN series horizontal sand pump is designed based on two-phase flow theory, featuring high hydraulic efficiency and excellent wear resistance. It maintains stable performance while conveying media containing solid particles, making it suitable for various applications such as sand dredging in rivers, lakes, and seas, land reclamation through sand blowing, river channel dredging, sediment clearing, embankment reinforcement, iron ore and tailings extraction, coal mining, power plants, and mining enterprises where solid-laden media need to be transported. It is widely used for sand dredger operations, loading sand vessels, and long-distance sediment transport on land. The pump can handle media concentrations of up to 50%, with particle sizes reaching up to 80 millimeters.
Product Features and Advantages:
- The pump is composed of components such as the pump casing, impeller, liner, shaft, shaft seal, support frame, bearing housing, and base. The pump casing, impeller, and liner are made from different materials such as gray cast iron, cast steel, and wear-resistant alloys, while the shaft is crafted from high-quality carbon steel. The support frame and other parts are made of ordinary cast iron.
- The single-pump casing structure allows for easy disassembly and maintenance. The design of the secondary impeller enhances its operational lifespan.
- The discharge outlet direction can be adjusted in increments of 45 degrees.
- The wide impeller flow passage can transport large particle media, with a conveyance distance of up to 2000 meters.
- Curved vanes on the impeller’s rear cover create negative pressure during operation, preventing slurry from entering the shaft seal. The gap between the impeller and the protective plate can be adjusted using adjustment screws on the bearing housing, maintaining consistent performance. The sealing mechanism employs a packing seal, which is simple and reliable.
- To protect the pump during operation, a special method is applied to the pump’s anti-leakage packing chamber. An auxiliary flushing pump is installed to direct clean water with pressure higher than the slurry pressure into the anti-leakage packing chamber. Mechanical seals can also be used across all pump types, eliminating the need for a flushing pump.
- The pump is driven using an elastic cylindrical pin coupling connected to the power unit. When viewed from the power unit’s perspective, the pump shaft rotates in a clockwise direction.

Kaplan turbine is a famous type of the reaction turbine. Kaplan turbine is a countercurrent axial turbine with regulating buckets. A turbine is called an axial turbine if fluid flows horizontally on the shaft axis of rotation. Kaplan turbines are axial reaction turbines because the water flows in an axial path.
In axial reaction turbines, the turbine shaft is perpendicular. The lower end of the shaft is larger and is called the boss or hub. Since the buckets attaches to the hub, the hub works as an impeller for the axial reaction turbines.
Professor Viktor Kaplan from Austria it in 1913. The Kaplan turbine is the development of the Francis turbine. The development of this turbine enables efficient power generation in low head applications that was impossible with Francis turbines. These turbines are widely using worldwide for low head, high flow power generation.

Common Usage of Check Valve
Check valve is a kind of valve that depends on flow of medium to open or close disc. Check valve is used to avoid back flow of valve.
Based on structure, check valve can be classified into lift check valve, swing check valve, butterfly check valve, pipe valve.
1. Lift check valve: The disc of lift check valve can slide along vertical center line of body. Lift check valve can be only used for horizontal pipeline. The disc of high pressure small caliber check valve uses ball. The shape of body of lift check valve is similar to globe valve. For that, resistance coefficient of fluid is large.
2. Swing check valve: Disc rotates around the pin roll outside base. Swing check valve is one of the most common used check valves.
3. Butterfly check valve: Disc rotates around the pin roll inside base. Butterfly check valve has simple structure and it can be only used for horizontal pipeline, having bad sealing.
4. Pipe check valve: Disc slides along the centre line of body. Pipe line is a new type valve. It has small volume, light weight and excellent manufacturability. Pipe line is one of development directions for check valve. However, resistance coefficient of pipe check valve is larger than swing check valve.

Construction of the new Lake Wohlford Dam is proposed immediately downstream of the existing dam. The left abutment of the proposed dam will conflict with the existing Oakvale Road, so the road must be realigned prior to the construction of the new dam.
The Oakvale Road Realignment Project will realign an approximately 1,200-foot section of Oakvale Road near the Lake Wohlford Dam, straightening the road and moving it toward the south. The realignment will require excavation into the adjacent hillside to remove approximately 56,000 cubic yards (cy) of rock and earth to create space for realigning the road, which would be shifted a maximum distance of approximately 150 feet to the south of the existing alignment. The existing roadway will remain in service during construction of the new roadway.
Estimated Construction Schedule – 365 calendar days; The City Council awarded the project to L.B. Civil Construction, Inc. on May 12, 2021, in the amount of $8,467,520. Construction began in July 2021 and is expected to be completed by March 2024.

Kier was appointed in January for the expansion project, which will double the 6.3MW power capacity of the scheme.
The existing plant, which was constructed in the late 1950s, is made up of a weir and intake, 2.2km of 1.8m diameter woodstave pipeline, 100m of rock tunnel, a pipe bridge and surge tank, as well as an existing powerhouse with one vertical axis Francis turbine. The woodstave pipeline is in need of repair and replacement and this project provides an opportunity to incorporate the existing elements into an expanded scheme to add 6.3MW capacity.
The project will include the construction of a new intake to double the design flow, alteration of the existing weir, dualling of existing pipelines, replacement of the woodstave pipeline with 2.6m diameter glass-fibre reinforced polyester (GRP) pipe and a new powerhouse housing two horizontal axis Francis turbines. Several elements of the existing scheme will be re-used, including 220m of concrete conduit, the rock tunnel and surge tank, subject to condition assessments and detailed hydraulic modelling.
Mott MacDonald will design all scheme components including the new intake, retaining walls, pipeline and powerhouse, with added support during construction. The consultancy will also provide detailed hydraulic analysis and flood risk assessment for the expansion as well as technical advisory services for the electrical and mechanical elements.
Sustainability has been a key consideration in the design, with the re-use of existing scheme elements where possible and use of modern materials such as GRP to reduce the embodied carbon footprint.
Mott MacDonald project director Gavin McGill said: “Jamaica is highly dependent on oil imports to meet its energy requirements. It is currently making efforts to reduce its reliance on these, with hydropower presenting a clean and reliable alternative. The existing Maggotty hydro scheme forms an important part of the country’s generating capability and our off-line construction design will aim to keep disruption to power generation to a minimum during the construction period.”
Construction is expected to start on the project late this year, with work due to be completed by the end of 2013.


GT-SUITE software was used to build the ORC system simulation model. Based on the simulation model, the effects of single screw expander speed and multistage centrifugal pump speed on system performance were studied. Based on the data obtained by Design of experiment (DOE), using machine learning, a system performance prediction model is constructed. At the same time, the system performance is predicted. The optimal operating performance of the system is determined according to the prediction results. The results show that in the common speed range of single screw expander and multistage centrifugal pump, there is an optimal matching value so that the net power output of the system reaches the maximum, and the optimal expander speed and the optimal pump speed are maintained at lower speed.

The 430MW Reisseck II pumped storage hydroelectric power project is located in the Mühldorfer Graben region of Carinthia, Austria.
The project was developed by Austria’s biggest electricity producing company, VERBUND, with an investment of €385m ($522m) and became fully operational in February 2015.
The output of the plant is enough to serve 30,000 households during periods of peak electricity demand.
Reisseck II pumped storage power plant development and financing
VERBUND developed the project in partnership with KELAG and Energie. KELAG holds 45% of the subscription rights in the project.
European Investment Bank provided €150m ($202m) of debt financing for the project.
Reisseck II pumped storage power project details
The Reisseck II power plant links the hydraulic systems of VERBUND’s two existing pumped storage power plants, Reisseck-Kreuzeck and Malta, in the Mölltal valley. Reisseck II utilises the existing reservoirs of these plants instead of constructing any new reservoir facilities.
Being used as a reservoir for the Reisseck-Kreuzeck storage power plant, Great Mühldorfer Lake functions as the upper basin for Reisseck II, while the Goßkar reservoir of the Malta main stage functions as the lower basin.
Water from the upper basin flows at a rate up to 80m³/s to the underground power station via a 5km headrace tunnel and an 800m pressure shaft. The powerhouse cavern, situated at a height of 1,585m above sea level, is equipped with two reversible Francis turbines of 215MW capacity each. The downstream connection is via a 203m tunnel into the lower basin.
Both generating units of the underground power plant are designed to serve as pumps, enabling the pumping back of water from the lower basin to the upper when the grid has surplus electricity.
Construction of the Reisseck II pumped storage power plant
Ground was broken for the Reisseck II project in August 2010, and the construction of the rock cavern was completed in 2011. The boring activity for the underground waterway to the Great Mühldorfer Lake was performed in 2012 with the use of a 220m tunnel-boring machine.
The assembly works commenced in 2012 and the hydroelectric generating sets were assembled at the power house cavern by mid-2013.
The block transformer with a tare weight of 200t is the heaviest among the equipment installed at the high-altitude power plant. The pressure pipes are made of steel with a diameter measuring more than 3m.
Contractors involved with the Reisseck II power plant
Andritz was awarded the contract for supplying and installing the motor-generators along with corresponding excitation equipment for the pumped storage power plant.
Bilfinger VAM Anlagentechnik was awarded the contract for supplying pressure tunnel plating and other piping system components.
Poyry Energy was awarded a €9.2m ($12.2m) contract for providing engineering services and site supervision works during the construction phase.

Building and maintaining levees
When the water level is high, the Demer Valley must be able to contain more water. Where it is possible to do so, the lowering or breaching of the levee is a necessary measure. This will allow more space for the river to flood at the appropriate places, thereby utilising the natural water storage capacity. This will allow the winter bed (the part of the river that is only under water in the winter) to be restored.
We will lower the levee at eight places along the Demer. Around the water storage areas, we will build new safety levees or we will elevate sections of the existing levee. The winter bed – the part of the river which is submerged in the winter − will be restored in certain places. This way we can create just under 2000 hectares of space for controlled water storage in the Demer Valley.
