Plastic Buffer tanks for rainwater

Retention tanks and buffer tanks are rainwater tanks to discharge rainwater in a calm, delayed and dosed manner. During heavy rainfall, rainwater from industrial sites, company buildings and residential roofs can be stored in a retention tank and (temporarily) buffered. This retention tank is equipped with a delayed drain, a swirl valve or retention hose. This delayed discharge ensures that the buffer volume in the rainwater tank is full as a result of the rainstorm and only a small amount (over a longer period of time) is drained to the sewer or watercourse. In this way the rainwater is temporarily buffered so that the peak load of the extreme rain shower is leveled off. This prevents flooding. The rainwater retention tanks are made of plastic and are interconnectable. The rainwater tanks are fitted with manholes on which the Varitank shafts of GEP fit. Then all kinds of connections can be made. The retention facility consists of a retention hose from GEP. These are available with different drainage capacities of 0.2 to 6 liters per second. Large flow rates available on request.
