Workers from Lake Whatcom Water and Sewer District (LWWSD) are on site working on Marigold Drive between Lake Whatcom Blvd and the Clubhouse. They are diagnosing a problem that is causing water to bubble up through a manhole cover and travel across the road. Flaggers will be on site to direct traffic around the closure. LWWSD estimates that the repair will take about three hours to complete.
LWWSD sent SVCA the following report at 6:30 PM on Wednesday, September 30:
Wednesday, September 30, 2026 at 1:50pm, the District administration office received a phone call from a customer that sewer was spilling out from a manhole on Marigold Dr inside Gate 2 in Sudden Valley. District staff investigated and determined that the manhole housed an air release valve associated with the force main from nearby Ranch House sewer lift station.
Pumps at the Ranch House sewer lift station were turned off at 2:14pm to stop any further release of sewage. District staff then determined that the air release valve had failed to seal the flow of sewage through the 3/8” exhaust port. Using flow data from the lift station during the estimated time of failure, it was determined that approx 700 gallons of raw sewage was released onto Marigold Dr approximately 200 ft in each direction of the manhole.
Wastewater did NOT reach Lake Whatcom or Lake Louise. The sewage that was released soaked into the ground on the southside of Marigold Dr. Media will not be notified via press release unless wastewater is believed to have reached a surface water body. The Washington State Department of Ecology ERTS tracking system was notified.
District staff washed the residual sewage off the road surface using a highly concentrated chlorine solution to disinfect the area. The air release valve was repaired and placed back into service.
