Detention & Retention

Detention and Retention Tanks

A detention tank is used to restrict flow into the council storm water system, and they stay mostly empty unless there has been a lot of rain. If the stormwater drains in your area do not have the required capacity, an engineer designed detention tank would be required.

A retention tank is used to hold water, which can then be used for your hose taps and toilets to save water, When used correctly retention tanks can be very useful and better for the environment.
