Concrete Buffer tanks

Retention citerns and buffer citerns are rainwater citerns for dosing rainwater and delayed discharge. During heavy rainfall the rainwater can be stored in a retention buffer citern. This retention well is provided with a delayed drain, a swirl valve or retention hose. This delayed discharge ensures that the buffer volume is full and only a small amount (over a longer period of time) is drained to the sewer or watercourse. The function of a retention citern for rainwater is clear; it is not so much the use of rainwater, but rather the temporary retention of rainwater. So flatten the peak of an extreme rain shower to prevent flooding due to rainwater. The rainwater retention citerns are made of concrete and are interconnectable. The rainwater citerns are equipped 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. You can also create a design of a rainwater system online via the online GEP rainwater calculation module.
