Underground Retention & Detention Water Tanks

Retention Water Tanks & Detention Water Tanks produced by Aqua Tanks are ideal for your local Council Stormwater requirements.

Detention Water Tanks are only required to slow the flow of stormwater. The stormwater which is piped into the tank is released through a smaller outlet in the bottom of the tank so it dribbles out at a slower pace. This practice is to reduce the pressure on the council stormwater system

Retention Water Tanks are required to retain the water in the tank so it can be used for household use and the overflow can be piped off to the council stormwater system.

Aqua Tanks produce a wide range of water tanks suitable for stormwater retention Tanks and stormwater detention tanks which can be installed as above-ground tanks or below-ground tanks depending on your requirements. The underground water tank range tanks covers water tanks from 495 litres to 5000 litres.
