Clogging Gone When Sewage Grinder Pumps up the Protection
The Channel Monster, custom fitted for Santa Ana manhole, slides down a guide rail for an easy access sewage grinder.
Pumps clogging with debris caused the City of Santa Ana to call for a Channel Monster sewage grinder. Contributing to the unbudgeted expense in maintenance, operators were having to break open pump fittings to reach the problem area, and pull the rag balls out, every time there was a back up in their system.
“We had to find a solution,” said Nabil Saba, P.E., Acting Water Manager for the City. “Every time the pumps would clog we had to go in there. It’s a confined space so, not easy. Every time we had to open the pumps and break the seals. And every time the workers are exposed to raw sewage.”
Built in 1977, the Santa Margarita reclaimed water facility was initially intended to provide water for landscape irrigation in the district. During a typical 12-month period today, the facility brings in 680 million gallons of sewage and sends out 620 gallons of reclaimed water. But starting in about 2012, the pumps would begin to lose efficiency as the wipes loading increased. All pumps, including standbys, would have to run to maintain plant production. Once they reached 60 Hz the plant would need to shut down to derag the pumps.
“This upgrade cost significantly less than purchasing a whole new set of pumps,” says Ron Johnson, facilities supervisor for the SMWD facility.
