Our Wastewater Source Control Program is a pollution prevention strategy which aims to protect our environment and watershed by reducing industrial, business, institutional and household chemicals from being discharged to the city sewer system and eventually back into the Lake.
As Okanagan Lake supplies drinking water to more than 60,000 residents in the Kelowna area, it is important to keep specific chemicals out of our precious water supply.
Additionally, some chemicals, drugs, and pharmaceuticals cannot be treated or removed at the City's Wastewater Treatment Facility (WWTF) and may affect treatment processes.
What can't go down the drain?
The Sanitary Sewer Storm Drain Regulation Bylaw details the specific wastes that are prohibited from being discharged to the sewer. Hazardous Waste should never be disposed of down the drain. See the Regional District of Central Okanagan or Recycling Council of BC for further information on recycling and disposal options for a variety of hazardous wastes.
The BC Medications Return Program provides detailed information on where to properly dispose of unused pharmaceuticals and medications.
