Stormwater retention retains the natural cycle

Local stormwater retention and detention is often required by law. As more and more ground is sealed with buildings, car parks and roads, the sewer system is having to work harder and the risk of flooding increases. GRAF stormwater detention and retention tanks are here to help. They make sense both ecologically and economically because they take the strain off the sewer network and save surface water drainage charges.
