Paris-Charles-De-Gaulle Airport - Stormwater segregation (France)
Stormwater segregation structure at Paris-Charles-De-Gaulle airport
Client: Eiffage - Aéroports de Paris - Scale: 1:10.33
Eiffage was appointed by ADP to build a stormwater management system covering the entire Paris-Charles de Gaulle airport. Prior to commencing the works, Eiffage commissioned Artelia to validate the design of the system’s central structure, whose aim is to segregate clean stormwater runoff and pollutants. For this purpose, Artelia suggested developing a hybrid numerical and physical scale model.
Numerical and physical scale model
- A physical scale model is used to study the entire approach zone and the intake zone. Its objective is to assess and, if necessary, correct the flows approaching the pumps in order to make sure they operate properly (avoid rotations and vortices).
- A 3D numerical model is used to study the discharge zone.
- A 1D numerical model is used to study the system as a whole.
Description of the physical scale model
The model represents:
- The upstream tank, which is connected to the supply outlet of the new segregation structure.
- The connecting outlet,
- The new structure consisting of a gravity flow channel for clean stormwater and a duct towards the pumping tank for the polluted water.
The model is designed to be modular and modifiable, should design modifications be deemed necessary.


Low Water Levels Force Closing Of Hinckley Boat Launch
With water levels nearly 15 feel below normal, the New York Power Authority has closed the Hinckley Dam and Reservoir. The NYPA said the extremely low water levels make conditions unsafe for boat launching. The canoe and kayak launch area are still open.
The launch consists of concrete planks that extend 200 feet into the reservoir. It is located along the north side of the reservoir on Route 365.
The NYPA said it will continue to monitor the water level in hopes of being able to re-open the launch.


The VERBUND Hydro Power GmbH operates the Zemm-Ziller power plant group in the Ziller Valley in Tyrol, Austria. The power plant group is one of the country’s most powerful storage power plant groups. The BERNARD Gruppe has been commissioned with the services of local site supervision and construction work coordination.
The power plants are automated and are monitored and remotely operated from the central control station in Mayrhofen in the Ziller Valley.The 25 kV cable connection between the power plant Mayrhofen and the power plant Häusling is part of the extensive 6/25 kV power plant grid of the VERBUND plant group. The aim and object of this project is the renewal of the 25 kV cable connection between the two power plants, which is necessary for the auxiliary power supply. The cable section will be realized in 2020.
All sections along the cable route from the power plant Mayrhofen to the power plant Häusling will be renewed, and the cables shall principally be laid underground. An exception is the section from the power plant Mayrhofen to the final guying point Oberkumbichl, which runs in a cable duct (approx. 1.6 km – concrete structure / collector) and where the cables will be fastened to the existing reinforced concrete surface by means of cable clamps. The total length of the line is about 10,650 meters.

Azerenerji Waiting for Iran’s reply on Construction of Border Power Grid
Azerbaijan, Baku / corr Trend S.Aliyev / The Vice President of Azerenerji joint stock company, Marlen Askerov, reported on 26 April that to date the Iranian energy specialists have not replied to a protocol on the construction of power grids in Nakhchivan Autonomous Republic. Azerbaijan has developed its protocol which is to be co-ordinated with Iran.
Previously, both parties co-ordinated the terms of the construction of the frontier power station in Nakhchivan Autonomous Republic of Azerbaijan. The project involves the construction of two power stations (one in Azerbaijan and the other in Iran) on the bordering Araz River in the Ordubad District of NAR.
The construction of the border power stations envisages the construction of stations with a similar capacity. Azerbaijan intends to build a power station with the capacity of 45 MW. The parties made a resolution that unless Iran builds power stations with a similar capacity, Azerbaijan would construct it in its own territory. Earlier Azerbaijan and Iran agreed to construct power stations on the Araz River. They agreed upon the construction of two power stations (one in each country) with the capacity of 45 MW, Ordubad Hydro-Power Station ( Azerbaijan) and Marazadagh HPS ( Iran). The water resources of the river will be shared equally.

The Memve’ele Hydroelectric power plant is one of the biggest in Cameroon with a capacity of 211 megawatts of electricity.
The constructions phase of the power plant that began in 2011 entered its decisive phase after signing of the work execution contract in April 2012.
The project estimated at CFAF 365 billion is located in Nyabizan on the Ntem River in the South region, 300 km from Yaounde.
The Earth fill dam is 20 meters high having a reservoir of 19 million m3 of water.
Water from the reservoir is channelled through the canal to the power house for the production of energy.
Following the completion of the construction phase, government signed another loan agreement in February 2017 worth 83 billion CFA Francs with Exim-Bank of China to finance the drainage of electricity from the hydroelectric dam.
This paved the way for the construction of 294 pylons between Nyabizan and Ebolowa to evacuate 211 MW of power from the dam to Yaounde.
The loan also financed the installation of 225 KV transmission lines and the construction and installation of three transformer substations with a capacity of 225/90 KV in the localities of Ebolowa, Nkoumou in the South Region and Ahala in the Centre region.
The project initially slated to end 2018 witnessed delays and an additional expenses.
The African Development Bank (AfDB) provided 112 billion FCFA while the Cameroon government disbursed 65 billion CFA Francs and Exim bank of China provided the remaining 243 billion CFA francs.
The Memve’ele Hydroelectric power plant is expected to provide sufficient energy to resolve the electricity deficit in the southern part of Cameroon.
The Memve’ele project is constructed by the Chinese civil engineering construction company Synohydro.
It is this company that built the Three Gorges dam in China, the world’s largest hydroelectric power station.


Veidekke to build Stockholm wastewater tunnel9 May 2022
Veidekke has signed a contract with Stockholm Vatten och Avfall AB for the construction of the new Östberga tunnel, which is part of Stockholm's future wastewater treatment system.
The contract has a value of approximately SEK600m (US$60m) and the tunnel is expected to be commissioned in 2026.
The new Östberga tunnel is an environmental improvement project intended to make Stockholm's wastewater structure more robust and able to handle larger volumes of wastewater and precipitation.
The project comprises two main parts. First, Veidekke will construct a 2.2km mountain tunnel for surface water, with two associated service tunnels, each approximately 250m long. The mountain tunnel will be fitted with a cast concrete floor, most of the pipe installations, and steel hatches to regulate water flow. The second part of the contract is the renovation and upgrade of an existing control chamber, and around 300m of new sea pipeline will be lowered and mounted on seabed piles.

Strathcona Dam Water Discharge Upgrade Project
About The Project
- Construct a new low-level outlet structure to provide the capability for a deep reservoir drawdown, which is currently not possible. This work includes construction of a deep channel and placing two gates in a concrete structure located within the bedrock on the right or east side of the dam. Post-earthquake, having a lower reservoir level will reduce the risks to the dam, and the controlled water releases from the dam also manages the risks to the downstream dams.
- Replace the existing three spillway gates and related works such as the hoist system with a new concrete overflow spillway, improving the reliability of the spillway system. With the two new gates to be placed within the new channel, in addition to the Strathcona Generating Station discharges, they will provide for downstream water management for fish, power generation and flood risk management.

The Akosombo dam is Ghana‟s main source of energy. Considering the current increase in the
demand for electricity in the country, where an increase in demand implies more pressure on the
dam, it is therefore very important to investigate the tail behaviour of the water levels of the dam.
This is necessary because the level of water in the dam determines the amount of electricity
generated. The study investigated this problem using Univariate Extreme Value Theory. Both the
Generalized Extreme Value distribution and the Generalized Pareto distribution were fitted to the
Akosombo data. The Generalized Extreme Value distribution performed better than the
Generalized Pareto distribution. Maximum likelihood estimation method was employed in the
estimation of the model parameters. The study indicated that the water levels cannot fall below
226.00ft., which is the critical water level of the Akosombo dam. However, there is evidence of
the dam attaining water levels below the minimum head operation level. We therefore
recommended that, other forms of power generation should be explored to reduce the
dependence on the Akosombo dam due to the fact that the dam can attain water levels below the
minimum head operation. We also recommended that to prevent flooding during periods of
excess water and abundant inflow, the high of the reservoir should be extended to retain the
excess water which is spilled out

A hybrid method for the simulation of Reynolds-averaged turbulent flows in axial flow impeller driven mixing vessels is described. The time-mean flow in the impeller region is modelled using blade element theory, while the flow in the remainder of the vessel is simulated using a second-order finite-volume Reynolds-averaged numerical scheme. The two models are iteratively coupled through boundary conditions and computation of the power dissipated in the mixing vessel. This approach is computationally cheaper than alternatives that require the details of the flow in the impeller region to be resolved. Simulation results are compared to a detailed laser-Doppler examination of the flow in a laboratory vessel, and it is shown that the average absolute difference between simulated and measured velocities was of the order of 1% of the impeller tip speed. In addition the power consumption was predicted to two-figure accuracy.

Hydro-Brake Flood Alleviation vortex flow controls have been installed as part of a new £3.1 million flood alleviation scheme in the North Yorkshire town of Northallerton.
The Environment Agency project aims to provide sustainable, low-maintenance flood storage defences based on sound SuDS principles.
Northallerton and its surrounded villages are situated in a low lying river valley, surrounded by steep, well-drained agricultural land which is susceptible to flash flooding. The town experienced major floods most recently in 2000, 2008 and 2012 which caused widespread disruption and damage including to the town’s Friarage Hospital.
In order to reduce the risk of flooding to homes and businesses in the town, vortex flow controls were installed upstream of the town’s refurbished culverts to protect flood-prone water courses. The flow controls enable excess water to be held back in specially built flood storage basins in agricultural land on the approach to the culverts.
The Turker and Sun Beck watercourses that run through the centre of the town cause major flood threats to amenities including Grade II listed buildings, conservation areas and listed monuments as well as the hospital.
At times of heavy rainfall, excess floodwaters can overtop the watercourse within the agricultural land on its approach to the culverts, sending flows to cause flooding in the east of the town.
The Environment Agency area project manager Ian Cooke commented: “The Sun and Turker Becks have repeatedly overtopped and threatened the town. That’s why, after consultation and looking at similar successful schemes in other areas, we decided to use upstream storage to reduce the flooding risk.”
The resulting scheme at the urban boundary requires little to no maintenance and is resistant to blockage. The Hydro-Brake Flood Alleviation flow controls can be carefully-sized to minimise the back-up storage volumes even under high rainfall conditions.
This means that the risk of the farm land on the outskirts of Northallerton flooding and threatening nearby developments will be minimal in the future.
Ian Cooke continued: “The scheme is designed to also improve protection to the area from flash floods. The design meets sustainable principles, by attenuating excess flows and allowing them to discharge at a controlled rate.”
The Hydro-Brake Flood Alleviation vortex flow controls are based on an industry-standard method of flow attenuation, which is often used in much smaller dimensions as part of urban surface water drainage designs.
For the project at Northallerton, Hydro sized the controls to create an optimal internal geometry which delivers the best hydraulic performance with the minimal amount of upstream storage.
In comparison to alternative flood control devices, such as orifice plates or penstocks, the vortex flow controls have a larger opening which allows more water to flow through the culvert unimpeded, meaning less flood storage is needed.
At the same time, the risk of blockages are reduced. Together with the fact that the flow controls have no moving parts or power-requirements, this means that minimal maintenance is required.
An 857mm outlet diameter Hydro-Brake Floow Alleviation vortex flow control was installed on the Turker Beck with a maximum design flow of 1 cubic metres per second.
The Sun Beck installation, sited upstream of the junction with Turker Beck, features a 684mm Hydro-Brake Flood Alleviation vortex flow control with a maximum design flow of 0.58 cubic metres per second, requiring 1,500 cubic metres of back-up storage.
The installation at Northallerton follows successful flood alleviation schemes built on the White Cart Water in Glasgow, the River Douglas in Wigan and at Weedon Bec in Northamptonshire.

Eden Dam is a series of irregular dikes originally built under the Carey Act by Eden Irrigation and Land Company about 1907. In 1959, the Bureau of Reclamation constructed a new outlet works from the reservoir through the abutment in the southeast side of the reservoir to supply the old Eden Canal.
The reservoir is approximately 2.5 miles at its widest point, and 2 miles in length with a surface area of about 1,100 acres.The outlet works consists of a concrete lined tunnel controlled by constant head orifice gates and an overflow control structure.
The spillway is contained in the outlet works as an uncontrolled concrete overflow structure above the orifice gates. The spillway has a crest width of 15 feet and crest elevation of 6713.5 feet. A 22 inch wood beam has been added to the top of the spillway to get a new crest elevation of 6715.2 feet. The spillway is used only in an emergency since the water inflow to the reservoir is controlled by diversions through the Little Sandy Feeder Canal.

Krpeľany hydroelectric power plant is part of the Krpeľaly reservoir constructed just downstream the Orava and Váh river confluence. Its first control stage of the highest-laying diversion cascade of HPP´s built on the Váh river, even if this plant only followed the Dubnica and Nové Mesto cascades in building the Váh water works. As the HPP capacity requirements, and in particular for peak-load electricity supply, have increased over time, its maximum useful flow is substantially higher than that of the lower-laying cascades – 3 x 70 = 210 m3.sec-1.
Slovenské elektrárne operates 31 hydroelectric plants. Their combined output is 1,652.7 MW, representing approximately 38.4% of the Company’s total installed capacity. Majority of the installations is located on the Váh River cascade, or the longest river in Slovakia. On average, the hydroelectric sources generate 2,070 MW annually (consumption of pumped storage power stations excluded), or some 11% of the electricity produced by Slovenské elektrárne.
Because of their very variable power output and operational flexibility, hydroelectric plants are capable to satisfy the swiftly changing demands in the daily-load diagram, pairing nicely with the base load supply covered by nuclear power plants. Slovenské elektrárne has 736.6 MW installed in river hydropower plants and 916.4 MW in pumped storage power stations.

Minister of Agriculture Noel Holder today met with a team from the World Bank to discuss the progress of the Cunha Canal Rehabilitation project. The project was officially signed on in February 2016 at the Ministry of Finance by the Finance Minister and World Bank Representatives. It will see rehabilitation of the drainage canal, construction and rehabilitation of sluices and the construction of a bridge on the East Bank of Demerara Public Road. The World Bank is injecting US $3M into the project which will ultimately improve the relief capacity of the East Demerara Water Conservancy system by lowering of the risk of water levels exceeding safe operating levels.
In addition to flood relief, the project will also satisfy a development objective which is to improve the drainage in agricultural areas on the East Bank of Demerara that drain to the Bandarima Creek and Sarah Johanna Canal. These areas will now be able to have an increase in agricultural production since areas that previously lodged water will be drained and available for cultivation.
Speaking on the progression of the project Senior Disaster Risk Management Specialist Mr. Armando Guzman stated that the Cunha Canal Rehabilitation project also included a compensation component that includes a one off payment to Berama Company Limited.
Under the Flood Risk Management Project, $11.9M USD was injected by the World Bank and implemented by the Agriculture Sector Development Unit (ASDU) under the Ministry of Agriculture. The project will see the reconstruction of 4km of the North Eastern Dam of the East Demerara Water Conservancy as well as the construction of three pump stations at Hope/Enmore, Lusignan and Buxton Friendship. Tenders were recently submitted for the reconstruction of the dam while tenders for the pump stations are expected to be advertised by the end of April 2016.
Minister Holder also enquired about the engineering aspect of the project as it relates to the construction of the dam and was assured the all the relevant studies were completed as it relates to the structure’s capacity to stand up to the challenges that the rainy season will bring.
The team of specialist will be collectively working with the Agriculture Sector Development Unit (ASDU) and the National Drainage and Irrigation Authority (NDIA) to ensure the project is successfully completed over the next three years.

What Are the Classifications of Brass Check Valves?
Brass check valve can be divided into lift check valve, swing check valve, butterfly check valve, pipeline check valve, slow closing check valve and diaphragm check valve according to its structure.
1. Lifting brass check valve
A check valve in which the disc slides along the vertical centerline of the valve body. The lift check valve can only be installed on a horizontal pipeline. The disc can be a ball on a high-pressure small-diameter check valve. The valve body shape of the lift-type brass check valve is the same as that of the globe valve (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 on the valve seat to prevent the reverse flow of the medium.
2. Swing brass check valve
The disc of the swing check valve is in the shape of a disc and rotates around the axis of the valve seat channel. Because the channel in the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for low flow rates and infrequent changes in flow. However, it is not suitable for pulsating flow, and its sealing performance is not as good as that of the lifting type.
The swing type brass check valve provided by check valve factory is divided into three types: single-lobe type, double-lobe type and multi-half type. These three forms are mainly divided according to the valve diameter, in order to prevent the medium from flowing or flowing backwards, reducing the hydraulic impact.
3. Disc brass check valve
A check valve in which the disc rotates around a pin in the seat. The disc check valve has a simple structure and can only be installed on the horizontal pipeline, and the sealing performance is poor. The structure of the butterfly check valve is similar to that of a butterfly valve. Its structure is simple, the flow resistance is small, and the water hammer pressure is also small.
4. The valve disc of the pipeline type brass check valve slides along the center line of the valve body
Pipeline check valve is a new valve. It is small in size, light in weight and good in processing technology. It is one of the development directions of brass one way check valve. However, the fluid resistance coefficient is slightly larger than that of the swing check valve.
5. Compression type brass check valve
As a valve for boiler feed water and steam cut-off, it has the comprehensive function of lift check valve and globe valve or angle valve.
6. Diaphragm type brass check valve
Diaphragm type check valve has various structural forms, all of which use diaphragm as opening and closing part. Due to its good waterproof properties, simple structure and low cost, it has developed rapidly in recent years. However, the operating temperature and pressure of the diaphragm type brass check valve are limited by the diaphragm material.

Thermal and Hydraulic Modeling of Road Tunnel Joints
This paper focuses on the use of the COMSOL Multiphysics® software to develop a 2D numerical model of expansion joints for road tunnels. The model was developed using the coefficient form PDEs interface. The model includes water and energy conservation equations. It takes into account the influence of temperature on liquid water saturation and hydraulic conductivity. Under proper boundary conditions, the model allows the temperature, pressure and seepage velocity fields around the joint to be evaluated. The model also allows solutions for different expansion joint problems to be tested. Examples of solutions to prevent the formation of ice in the expansion joints during winter are presented. The model also shows how the temperature gradient close to the joints can be used to estimate their permeability.

The effect of centrifugal pump mechanical seal device -
according to China's petrochemical industry statistics, more than 80% of the shenzhen adopts mechanical seal centrifugal pump manufacturer. Due to the different working conditions, the centrifugal water pump in the process of conveying material, frequently, materials of mechanical seal leakage, environmental pollution, waste of energy.
is one of the main vulnerable parts of centrifugal pump mechanical seal, so most of pump failure is caused by the seal failure. According to statistics, mechanical seal failure caused by pump failure accounted for more than 50% of the equipment failure rate, so it is necessary to analyze the centrifugal pump mechanical seal leakage and to improve, in order to reduce the failure rate of the pump.
a, the working principle of centrifugal pump, and the role of the mechanical seal device
a centrifugal pump with a high-speed rotating impeller motor and coupling. The liquid between the blades are driven leaf. Under the action of centrifugal force, pump the liquid from the center to throw around. When pump the liquid from the impeller center to the edge, the low pressure area in the center. Because of the liquid before entering the pump pressure is greater than the pump inlet pressure, under the action of pressure difference, liquid through continuous, in the suction pump suction pipe is to supplement the discharged liquid position. As long as the impeller to rotate, the liquid will be overtaken by suction and discharge.
when the pump shaft through the pump shell, when the gap between moving parts and parts, pump the liquid will leak out of the pump from the gap. If is vacuum suction side, the outside air leakage into the pump, the serious influence the operation of the pump. In order to reduce the leakage, the shaft end sealing device is generally installed in a static clearance. The shaft sealing device is an important component of the centrifugal pump, is directly related to the normal operation of the centrifugal water pump. Now generally adopts mechanical seal shaft sealing device.
2, the principle of mechanical seal
mechanical seal is a kind of axial end face sealing device, it relies on elastic element, and intermediate pressure compression static ring end face seal preload pressure of elastic element to realize seal.
mechanical seals are usually made of static ring, ring, compaction of components and packing element. Ring and static ring end face to form a pair of friction pair, ring through the liquid pressure in the sealed chamber to static ring end face of the pressure on the two rings on the end face of the two rings on the end face of the appropriate specific pressure, and maintain a very thin liquid film to achieve the purpose of sealing.
when the pump is not running, pressure produced by extrusion device can ensure the pump end face each other contact, to ensure that the sealing medium not leak, and to prevent debris from getting into the seals. The space between the sealing ring seal ring and shaft, seal static ring and the space between the gland, and buffer pump vibration and shock. Mechanical seal in the actual operation is not an isolated parts, it is combined with the other parts of the pump running.
three, mechanical seal auxiliary facilities - — Flusher
flushing device is the most important auxiliary facilities of mechanical seal. In the process of pump operation, must flush sealed cavity formed deposit or impurities. Otherwise, the static mechanical seal ring will lose its floatability, spring will be due to the crystallization and precipitation of granular impurities. What's more, wear particles and impurities into the friction pair will aggravate the wear, lead to mechanical seal failure quickly. Therefore, in general, the pump mechanical seal shall be flush.

The hydropower facility is built in extreme natural conditions: permafrost in the region is 300m thick and outside winter temperatures goes down to 60 degrees centigrade below zero.
Lengidropoject developed the design of the power plant back in the 1980’s. The site preparation began in 1991, but the work progressed very slowly due to insufficient financing. De-facto construction resumed only in 2008 when RusHydro took over the project.
The dam across Kolyma River was completed in 2011. The first phase of the plant was commissioned in 2013 including two hydropower units equipped with two temporary 84MW runners, operating with a 32.5m high earth-filled dam. The second phase includes the third hydropower unit with the regular 142.5MW runner designed for 48.5m dam.
The third phase of the project includes increasing the dam to 66m, replacement of temporary runners with regular more powerful ones and commissioning of the third hydropower unit. Completion of the third phase would allow the plant to reach project capacity of 570MW and long-run annual output of 2.55 billion kWh. The overall length of the earth-filled dam and two concrete dams upon completion will reach over 2km. Commissioning of the fourth hydropower unit is scheduled for 2023.
All main equipment of the plant, such as turbines, generators and power transformers is manufactured in Russia. The plant is being built by RusHydro’s controlled company - JSC Ust-SrednekanHESstroi.

Multidisciplinary Design Optimization of a Hydraulic Poppet Valve Considering Fluid-Solid Coupling
Hydraulic poppet valve often works in fluid-solid coupling state. It is necessary to comprehensively consider the multidisciplinary coupling effects in the design and optimization of poppet valves. This paper presents the fluid-solid coupling model for the optimization of a poppet valve, and the actual flow performance of the poppet valve is analyzed by numerical method. By coordinating the conflicting requirements at the system level, the MDO model of the poppet valve is built. The Multiple-island Genetic Algorithm is employed to solve the optimization problem, and an optimum design of the poppet valve is obtained. The optimization results show that the optimum poppet valve has a better performance on the flow characteristics.
