Retention/Detention Systems

Retention/Detention Systems

Stormwater detention systems are designed to collect stormwater run-off for a period of time and slowly release the run-off into the public Stormwater system. They are commonly used for flow control and to meet release targets.

Stormwater retention systems are designed to retain stormwater run-off for on-site use, and only the overflow is directed to the public stormwater system. Detained water is commonly re-used on site.
