How do flush diversion systems work?
Flush diversion systems are fairly complex.
- Rain begins to fall on a facility and is measured with a rain gauge.
- Rainwater is diverted to a wastewater treatment system until the limit of 10 mm is reached.
- The diverter is then shut off, allowing excess rainwater to overflow in stormwater systems.
- If programmed, the diverter can reactivate for insufficient rainfall, or if a wash gun is activated.
