Bioteg - Model WES Series -Sewer Infiltration Water Stop

Application: The sewer infiltration water stop WES-600/625/800 is used for the restraint of surface water from manholes of the sizes DN 600,625 resp. DN 800. It is used in all cases where sewer infiltration of surface water during rainfall should be reduced or prevented. During rainfall an integrated float reduces the water flow into the manhole. The ventilation of the sewer system keeps working after installation of the WES. After storm water only a minimal water flow of 8,5 l/min is necessary to empty the WES again.
