What is the difference between a rainwater tank and a stormwater tank?
A rainwater (retention) tank captures roof runoff for ongoing use; ideal for irrigation, household appliances, and firefighting reserves. A stormwater (detention) tank only holds peak flows after heavy rain, then releases them slowly through an orifice to protect council drains; no long-term storage is intended. Many builders now specify combination retention/detention systems, and Polymaster supplies certified solutions for both requirements.
