MAK Water | Single Pit Storm Water Diversion SystemsGet latest price

Typically a diversion system would work in conjunction with a wastewater treatment system such as an Oil Water Separator;(OWS), Gravity Clarified;(GC) or Dissolved Air Flotation; (DAF) system. During a rain event, diversion systems allow clean rainwater to be harvested or discharged to the storm water system.

Process Description 

• Demand Driven - Diversion systems are a simple system using only a hydraulic demand valve without a controller. When the wash down activity has stopped, the diversion valve will close allowing rainwater falling on the designated area to divert to the storm water system.
• First Flush - Diversion systems use a PLC controller in conjunction with a first flush manifold located in the washer feed line to open/close the diversion valve. Once the first flush has been taken, the diversion valve will close allowing all subsequent rainwater falling on the designated area to divert to the storm water system.
• Wash-Down Shutdown - Diversion systems incorporate the same features of the first flush system with the addition of a shutdown feature in a rain event. A rain sensor is used to signal a rain event to the controller, which then shuts off supply to the washer for the duration of the rain event. This feature stops any cross contamination between the sewer and storm water connections and is a requirement in some localities.
