Avantages
Compactness : optimised design thanks to high-performance and well-dimensioned internal equipment
High performance : built-in flow control, dimensioned to prevent any overflow as long as the nominal flow rate has not been reached
Adaptability : tailored design making it possible to consider many configurations with networks up to DN 1200 mm
Easy to implement : structure factory equipped and set, ready-to-install
10-year warranty via insurance supplemented by an Epers
Demande d'informations
Taille : Up to a controlled flow rate of 450 l/s
Application
Structure intended to control the flow rate towards the treatment and to manage excess flows via overflow on rainwater or combined networks
Descriptif
Spillway of regulated flow to storm including a FLOREG type of flow regulator and a nappe respecting the hydraulic network.
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 600 µm thick
Flow rate controller made from 304L stainless steel of the FLOREG type
Headwater dimensioned to remove the peak flow rate in compliance with the hydraulics of the network
Fonctionnement
Controlled flow storm water overflow of the DOVR 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.
Options
