Ausdrain EnviroModule™2 Detention Tanks can be easily installed on any project, saving valuable time, labour and money. Compared to a concrete tank, there are no footings/slabs, blockwork or reinforcement required.
Each tank is sealed with a strong and durable waterproof liner. Ausdrain EnviroModule™’s create the required void storage allowing stormwater to be temporarily stored inside the tank before discharging to a designated outlet.
EnviroModule™’s are available in standard duty, suitable for installation under landscaped areas, or extra duty, for trafficable situations such as carparks or driveways.
The modular nature of the tank allows greater scope for design flexibility and tank sizing.
Stormwater is pre-filtered via an EnviroSump or GPT. This provides valuable at source water quality benefits and reduces the need for long-term tank maintenance. The water then enters a pre-cast pit that is fitted with an orifice plate to reduce the rate of discharge from the tank to the designated stormwater outlet.
Ausdrain’s EnviroModule™2 Onsite Detention Tanks are available from small tanks for residential projects, to large detention systems for commercial applications. Council approval should always be sought prior to installation.
