The Vashon Pool, which traditionally opens for the season on Memorial Day weekend, will open June 15 this year.

The decision to delay the opening was made last week and announced in a joint statement by Elaine Ott, the executive director of the Vashon Park District, and school district Superintendent Michael Soltman.

Representatives from both districts are working to find a solution for the pool, which had previously drained into the old high school’s septic field. Current regulations do not allow for that, and workers, believing the sewer pipe that led from the pool and its filtration system was an old, abandoned line, capped it last fall — a situation that came to light just last month.

Now, Ott said, it seems that a long-term solution — an infiltration field — can be built this spring, far earlier than anticipated. Moving ahead with this plan, Ott said, means that the pool staff has stopped its efforts to open by the end of May and will not spend the remainder of the money it had allocated to do so.

It is unclear yet what the cost of the solution will be, though Ott said both she and Soltman are exploring options for funding it, including whether or not insurance might cover a portion of the cost.
