Stormwater Overflow May Pose Health Risk on Eastern Shoreline of Victoria

Dec 13, 2010

Victoria, BC - Extremely heavy rainfall is currently resulting in combined stormwater and waste water overflows on the Eastern shoreline of Greater Victoria.

Residents are advised to avoid swimming or wading in waters along the eastern coastline, as the wastewater may pose a health risk. Wastewater (sewage), heavily diluted by stormwater is now flowing into the ocean at several outfalls in this area. The area affected runs from Finnerty Point, near Queenswood, to Clover Point, on Dallas Road.

"Heavily diluted sewage overflows are being caused by long duration, heavy rains, challenging the region's sewer infrastructure," said Ted Robbins, Senior Manager of CRD Water Management.

Stormwater overflows are caused by inflow and infiltration (I&), which is rainwater and groundwater that enters the sanitary sewer system. A certain amount of I&I is unavoidable and is accounted for in sewer design. However, when I&I exceeds typical amounts like during major storm events, sewer capacity is overwhelmed and may result in overflows. The Eastern shoreline is especially prone to I&I because of older sewer collection system infrastructure.
