3000-5000 Gallon Sewage Spill closes Blakely Harbor: Updated

BAINBRIDGE ISLAND — Kitsap County health authorities have issued a no-contact advisory for Tani Creek and the head of Blakely Harbor following a sewage spill at the Fort Ward treatment plant.

The spill occurred Friday through a 1-inch rupture in a digester tank containing liquid sewage sludge. At first, plant operators believed the spill had been contained near the facility, according to Stuart Whitford of the Kitsap Public Health District.

When he came to inspect the plant on Monday, Whitford discovered that the sewage had spilled down a 75-foot cliff and into a wetland, where it was partially contained by logs and other debris. A portion of the waste drained into a tributary of Tani Creek, then into the wetland and into Tani Creek itself before reaching Blakely Harbor.

Sewage cleanup planned at Fort Ward

Friday, April 6, 2012

BAINBRIDGE ISLAND — Officials at Fort Ward Sewer District 7 are working on a plan to clean up an estimated 4,000 gallons of sewage sludge that spilled into a nearby wetland, according to Stuart Whitford of the Kitsap Public Health District.

As a precaution, a no-contact order remains in place for Tani Creek and Blakely Harbor, although water-quality tests suggest that little contamination reached the stream and bay, he said. Hay bails have been placed at the outlet of the wetland to reduce the likelihood that the sewage can escape.

“We’re pretty confident that the material is trapped within the wetland,” Whitford said.

Officials have estimated that 10,000 gallons of liquid sewage sludge initially spilled from the 40,000-gallon digester tank on March 30, and about 6,000 gallons were contained and removed at the treatment plant. At first, sewer operators were not aware that 4,000 gallons had spilled down a steep slope and into the wetland.

Washington Department of Ecology and the city of Bainbridge Island will oversee the cleanup, which is expected to begin Monday. A suggested plan is to pump the waste uphill from the wetland.
