The new residential development at Denman Prospect ACT in the Molonglo Valley district of Canberra is located west of the Canberra CBD. Australian tanks were contracted to install a combination water retention and water detention system under the driveway of a residential complex. 175kL of retention and 31kL of detention were required.
Teaming up with Milin Builders, Australian Tanks was selected over other local tank installers because of our cost-effective pricing. Our design had the ability to install both a water retention system and a water detention system at the same time. This unique design help in reducing logistical cost and time.
Australian Tanks supplied and installed 8 x 25kL round tanks for retention allowing storage of 175kL. These retention tanks are connected at the bottom by Gibaults and penetrations at the top for PVC pipe connections.
5 x 7kL rectangular tanks were supplied and installed for water detention. This allows controlled flow of any surplus water in compliance with local ACT guidelines.
Both systems are connected by 300mm PVC piping and were installed under the driveway, minimising the impact on other parts of the job site such as foundations.
The quick and easy installation process was a great solution for the customer. The ability to immediately backfill and become trafficable was greatly appreciated by this client to keep the project on time.
