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.

StormTrap® offers the industry’s best solutions for managing runoff, protecting waterways and improving the use of your property. Our stormwater management systems are designed to reduce overall footprint, accommodate any site restraints, and lower overall costs.
