Weather forecasts for the weekend predict heavy rainfall. This could cause overflows in the sewer system, and Monica Van der Vieren, of the King County Wastewater Treatment Division Community Relations, wants everyone to know who to contact in case of problems – now or any time.
For odor complaints, stormwater or wastewater overflows, and flooding or drainage problems go to http://www.kingcounty.gov/environment/wtd/Response.aspx . The City of Seattle also provides emergency weather tips for drainage and sewer systems on the web.
The wastewater system in the Fremont area is part of the combined service system, which conveys both stormwater and wastewater flows. During heavy rains, when stormwater entering the combined system can exceed system capacity, combined sewer overflows (CSOs) can occur through permitted outfalls that serve as relief valves. In Fremont, both the City of Seattle and King County have permitted CSO outfalls on the Ship Canal. More information about the county’s CSO program, location of CSO facilities in North Seattle, and real-time notification of CSO events can also be found.
These CSO events have recently been mistaken for problems with the Fremont Siphon. At this time, the Fremont Siphon remains intact and functioning as designed. For more information about the Fremont Siphon, read the column on the Fremocentrist.com home page. In any case, if you see a problem – or experience one personally – please contact the County, City or 9-1-1 to report it immediately, before a problem turns into a tragedy.
