Reliable self-monitoring of spilled flows

To meet the expectations of the decree of 21 July 2015 by implementing a self-monitoring system enabling reliable measurement of the spilled flow.

The josette

The josette is a sill with a rounded notch dimensioned on a case-by-case basis according to the expected flow range so as to minimise the measurement uncertainty without significantly impacting the rise in the upstream water level.

Reduction of spills

Limit discharges from the sewerage network into the receiving environment via storm overflows and optimise implementation costs for the project owner. Exploiting the storage capacity of the network for current rainfall and maintaining the network's evacuation capacity for intense rainfall.

The StockO valve

The StockO valve is installed downstream of a manifold used for online storage. The tilting valve allows the volume stored in the network to be regulated.

The Deomatic valve

The Deomatic valve makes it possible to limit waste water discharges from storm overflows. The tilting valve replaces the overflow threshold to allow dynamic management of the network.

The Deomatic and StockO valves allow dynamic management of the sewerage network. The integration of this equipment in a network model allows the storage capacity of the collectors to be evaluated without degrading the initial operation of the sewerage network. The laws of 
The operation of the valves can be custom calibrated using the tool available below.

Fighting deposits

Controlling deposits and limiting their re-suspension in the sewerage network in order to maintain the evacuation capacity and minimise the risks of malfunctions such as polluting spills, blockages, flooding, etc...

The Carriage Trap

The cart trap makes it possible to trap and store sands while allowing most of the lighter organic matter to pass through.

The volume required is therefore lower than that of a conventional grit chambers. This also avoids bad odours for the local residents and makes the conditions for the operating staff much less dangerous and painful.

 

The installation of flush valves upstream enables the structure to be supplied by limiting deposits in the network.

The flush valve

The function of the flush valve is to create a water reserve upstream of the sedimentation and then to release the stored volume of effluent abruptly. 

Effluents released under high flow and speed will re-suspend the deposited sands, which will then be carried from upstream to downstream.

The know-how of HYDRASS 3D WATER

3D EAU and HYDRASS join forces to offer global solutions (studies + equipment) combining the efficient and pragmatic approach of HYDRASS and the precise hydraulic approach of 3D EAU.

  • The Deomatic valve to limit and measure discharges with the aim of achieving self-monitoring and collection compliance in wet weather: efficient and robust equipment supplied with the height-flow relationship developed to measure.

  • The Carriage trap to decant sands without retaining odour-generating organic matter, which is a major problem for operators.

  • The dredging valve to minimise the intervention of the operating agents in the collectors subject to the deposit.
