POULSBO — The Kitsap Public Health District issued no-contact advisories for several bays March 10 because of sewer and stormwater overflows in Poulsbo and Lemolo, and a combined sewer overflow in Bremerton.

The three overflows were different in size, so the duration of the health advisories is also different, the health district reported. The first no-contact advisory is for Liberty Bay and Nesika Bay, in effect until March 15. The second is for Port Washington Narrows, in effect through March 13.

According to the Poulsbo Public Works Department, a sewer and stormwater overflow occurred near the intersection of Highway 305 and NE Sol Vei Street, south of Poulsbo. It flowed through the city’s stormwater collection system to Liberty Bay, near the Liberty Bay Marina. The overflow was estimated at 6,000 gallons.

Kitsap County Public Works Sewer Utility Division reported a sewer and stormwater overflow from a sewer main on Norum Road in Lemolo, south of Poulsbo. The overflow was estimated at 5,000 gallons.

The City of Bremerton reported a combined sewer overflow of 2,461 gallons of sewer and stormwater that occurred between 1:06 and 1:08 a.m. March 10. This overflow, caused by heavy rainfall, occurred at an outfall located at the north end of High Street. Under these conditions, the system functioned as designed, discharging excess flow into marine water to prevent the back up of sewage into individual homes and businesses, the health district reported.

During a no-contact advisory, the public is advised to avoid contact with the water in the affected area. This means no swimming, wading, or types of water play where water could be swallowed or get in the mouth, nose or eyes. People should also avoid direct skin contact if possible, and immediately wash with soap and water if they have exposure to the water. Boats and kayaks should also be cleaned after exposure to the affected area.

Kitsap Public Health also recommends not harvesting shellfish anywhere in Kitsap County during and following heavy rain events, because of the increased risk of illness from water-borne pathogens and pollution.
