Retention – Detention Rainwater Tanks

With a simple T-Junction pipe fitting a Thin Tank can become a Retention- Detention Tank.

Retention Detention Water tanks are becoming a requirement with Councils around the country on any new build homes or houses that have renovations under the old storm water drainage system. With a simple T-Junction pipe fitting installed half way down the tank, a Thin Tank can become a Retention- Detention Tank. The fitting allows half the volume of the tank to flow at a slow pace into the storm water system while retaining the other half in the tank for normal use such as watering the garden, washing the house or car.
