DOHR
Horizontal storm water overflow system
Control of the restored flow and management of peak flows while respecting the network hydraulics
Advantages:
- Compactness: optimised design through high-performance andwell-dimensioned internal equipment
- Adaptability: tailored design making it possible to consider manyconfigurations with networks up to DN 1200 mm
- Easy to implement: equipement are delivered set and regulated in our factory, ready-to-install
- 10-year warranty via insurance supplemented by an Epers
- High performance: built-in flow control, dimensioned to prevent anyoverflow as long as the nominal flow rate has not been reached
- Equipement particularly suitable for long discharging blades
Size:
Sizing upon request
Application:
Structure intended to control the flow rate towards the treatment andto manage excess flows via overflow on rainwater or combinednetworks
Design:
- Made from S235 steel assembled on flat bottoms, protectedafter SA 2.5 sanding according to ISO 8501-1 with a hotpolymerised polyurethane coating 500 µm thick
- Flow rate controller made from 304L stainless steel, FLOREG or REGULO device
- Headwater dimensioned to remove the peak flow rate incompliance with the hydraulics of the water network
Operation:
Controlled flow storm water overflow of the DOHR type is designed anddimensioned for a perfect control of the flow rate to treatment.The controlled flow is reached before any overflow. Excess flow rates are managedby the overflow in compliance with the hydraulics of the network.Each structure is subject to a hydraulic validation using the data of the project.
