Sewer spill information
Vallecitos recently experienced an overflow of approximately 40,000 to 60,000 gallons of wastewater that spilled out of a pressurized sewer pipe (force main) located in front of Vallecitos’ sewer lift station in Lake San Marcos. The cause of the spill was due to the failure of the bonnet, or top of a 12 inch valve that was on the discharge side of the pumps out in the street.
Alarms in place notified Vallecitos staff of the spill at 8:45 p.m. on April 26, 2016. Crews responded immediately, recovering and preventing as much of the overflow as possible from reaching the lake. The spill was contained by 2:00 a.m. and repairs are expected to be completed by noon on April 27, 2016.
Cleanup and recovery is currently in progress with six pumping trucks on-site to remove as much of the wastewater as possible. The valve is in the process of being repaired. The proper agencies have been notified and, per the request of the County Department of Environmental Health, Vallecitos crews posted signs at Lake San Marcos where human contact may be possible.
UPDATE 5/7/16: The County Department of Environmental Health has approved the removal of the contamination signs at Lake San Marcos. Water quality testing was performed that showed that the water quality at the lake has returned to normal. As a result, lake uses can also return to normal.
