Diversion and Pumping Works
HBMWD installed five Ranney Collectors in or adjacent to the Mad River during the 1960s. The collectors draw water from the aquifer below the Mad River in perforated lateral pipes located approximately 60 to 90 feet beneath the bed of the river. The process of drawing water from the aquifer below the river bed provides a natural filtration process which results in water that is very high quality.
Currently, four Ranney collectors are operational. Today, they supply water to the HBMWD’s domestic system for drinking water purposes. In aggregate the Collectors are capable of producing approximately 20 to 21 MGD.
Hilfiker Pump Station No. 6 was constructed in 1976 to supply industrial water to the pulp mills. It is a direct diversion facility which is capable of pumping 60 MGD.
