DOHR
Horizontal storm water overflow system
Control of the restored flow and management of peak flows while respecting the network hydraulics
Avantages :
- Compactness: optimised design through high-performance and well-dimensioned internal equipment
- Adaptability: tailored design making it possible to consider many configurations 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 any overflow as long as the nominal flow rate has not been reached
- Equipement particularly suitable for long discharging blades
Taille :
Sizing upon request
Application :
Structure intended to control the flow rate towards the treatment and to manage excess flows via overflow on rainwater or combined networks
Conception :
- Made from S235 steel assembled on flat bottoms, protected after SA 2.5 sanding according to ISO 8501-1 with a hot polymerised 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 in compliance with the hydraulics of the water network
Fonctionnement :
Controlled flow storm water overflow of the DOHR type is designed and dimensioned for a perfect control of the flow rate to treatment. The controlled flow is reached before any overflow. Excess flow rates are managed by the overflow in compliance with the hydraulics of the network. Each structure is subject to a hydraulic validation using the data of the project.
