Equipment designed to optimise the management and maintenance of your wastewater network.
Following our acquisition of HYDRASS, we now have 30 years’ experience in developing products for sewerage networks, adding to our own expertise in hydraulics.
We develop, manufacture and supply simple, robust equipment to optimise the operation of public sewerage networks:
- Ease of use: although technical, our equipment is designed to be intuitive, enabling technicians or water operators to use it effectively in the field, in sewer pipes or combined sewer overflows;
- Product robustness: built to last, our devices withstand harsh conditions and operate reliably for decades.
- Efficiency: by reducing spillage and making it easier for operators to work in the field, our products help to optimise the operation of wastewater systems;
- Made in France quality design: designed by our teams in Paris and Strasbourg, then custom-made in our workshops in Troyes and Lyon, we guarantee the reliability of our equipment as well as rigorous quality control.
Let’s work together to create a more sustainable future!!
Do you want to combat deposits ?
The charriage trap
The charriage trap is a patented device. It traps and stores sand while allowing most of the lighter organic matter to pass through. The volume required is therefore smaller than that of a conventional sand trap. It also prevents unpleasant odours for local residents. Lastly, it improves working conditions for operators, making them less dangerous and arduous.
The flush valve
The function of the flush gate is to create a reserve of water upstream of the sedimentation, then to suddenly release the volume of stored effluent. The effluent released at a high flow rate and velocity will suspend the deposited sand, which will then be carried downstream.
Do you want to reduce spillage?
The storage valve
The storage valve is used to limit the discharge of wastewater from combined sewer overflows. It is installed downstream of a collector used for in-line storage. It is made to order in our workshops in France.
Our team of experts in urban hydraulic engineering is on hand to advise you on the solution best suited to your needs and the configuration of your site. Let’s work together to create a more sustainable future!
The storage and control valve
The storage and regulation valve is a patented device. It allows storage in a collector, optimising the space available in the existing network. An orifice at the bottom of the valve allows water to flow out when flows are low or when the weather is dry. In the intermediate position, the valve is partially open to prevent overflow but maintain a water level. Finally, in the event of heavy rain, the valve is fully open to discharge the water.
Would you like to check the self-monitoring of discharges?
Self-monitoring control device
Josette weir
The control device is used to check the height measurement of self-monitoring devices from the surface in accordance with regulatory expectations.
The control device is used to check the height measurement of self-monitoring devices from the surface in accordance with regulatory expectations. The josette is a weir with a rounded notch sized on a case-by-case basis according to the expected flow range, so as to minimise measurement uncertainty without significantly impacting the rise in the upstream water level.
Want to trap macro-waste?
Float traps
Float traps trap macro-waste floating upstream of a discharge point. It therefore provides a solution for reducing the amount of waste present on the surface of your sewer system.
