Product details

Stormwater detention tanks gradually release rainwater into the sewer system. This relieves the public sewer system and for this reason stormwater detention tanks are already mandatory in some places in new housing areas. Often a detention tank also has financial benefits in offsetting the impermeable area and thus in terms of the stormwater utilty fee.
