The Role of Retention and Detention Tanks in Stormwater Control
The management of stormwater is becoming more important as our cities and towns grow and our expectations that excessive runoff water during storm or high rainfall events will be managed and minimised. Stormwater tanks are an integral part of stormwater management systems.
Stormwater retention and detention tanks are often required to be installed by councils to manage water runoff. When choosing a stormwater tank for stormwater collection, the level of contamination of the runoff water will determine the type and design of the tank along with the associated equipment. If the water is highly contaminated, it may need to be treated even before it makes it to the stormwater tank. This will add another step in the stormwater management process and something that Bushmans will walk through with each customer. Call one of our qualified consultants or enquire online and let us assist you in choosing the perfect stormwater tank for your specific needs. The next issue is the release of the water back into the stormwater management system.

Stormwater Detention Tank
Stormwater detention tanks are designed to hold water for a short period of time and then slowly release it back into the stormwater system following a storm. The primary goal of stormwater detention tanks is to act as a support system to the drainage infrastructure by overcoming capacity constraints in the drainage system.
