1800 062 064 Rainwater Retention Detention Tank
CONTROLLED RELEASE INTO STORMWATER SYSTEM
What are Retention – Detention Tanks?
Retention and Detention tanks are often prescribed by councils and government bodies to control the release of water into the stormwater system.
All Polymaster above-ground rainwater tanks (round or slim) can be adapted to meet your retention or detention needs.
Detention Function
In the event of heavy rainfall the upper portion of tank temporarily contains the water surge. This process is known as stormwater detention and takes the pressure off municipal stormwater systems with this water being slowly released through a small outlet.
Available from 200L to 50,000L
