Wastewater Operations During PSPS Outages

FOR PROPERTY OWNERS WITH PRIVATE, RESIDENTIAL,

 “PUMP TANK SEWER SYSTEMS “

                                      for the Communities of                                             Penn Valley, Lake Wildwood, Eden Ranch, Lake of the Pines, Darkhorse and Mountain Lake Estates


Operations of Equipment 

During power outages, sewer systems that operate on private residential pump tanks within the communities of Penn Valley, Lake Wildwood, Eden Ranch, Lake of the Pines and Dark Horse and Mountain Lake Estates, will not be functional.  All wastewater deposited into the tank will simply accumulate and have nowhere to go, potentially creating overflows and hazardous spills.

Water Conservation

It is imperative that during these extended power outages , residents conserve water usage as much as possible.  This includes flushing of toilets, wastewater from sinks, tubs and showers as well as laundry and dishwashers.

Use of generators

Pump tanks will not be operational until either power is restored or unless the system has been professionally added to a whole-house, back-up generator by a licensed electrical contractor.  It is highly discouraged that portable generators be used to operate pump tanks.

Alarms

Once power is restored, be prepared for alarms to go off on systems.  It is not necessary to contact the Sanitation District regarding the alarm once the power has been restored unless it is in conjunction with a spill.  Field technicians will be making the rounds at that time and checking on systems throughout the District.

 Overflows & Spills

If an overflow or spill occurs, please immediately contact the Sanitation District at (530) 265-1555.

We ask that residents are patient during this event and once power is restored.  We greatly appreciate your cooperation.
