Mercer Island Important Homeowner & Contractor Information

The existing sewer line on the Mercer Island was installed in the mid-1950s, and is constructed of asbestos-cement (AC) material. The line has been suffering ongoing pipeline deterioration, capacity deficiencies, and other operation and maintenance problems.
Sewerscope for these Residential homes is recommend.


In an effort to assist the Puget Sound Clean Air Agency in the enforcement of local and federal requirements concerning abatement of asbestos, the City of Mercer Island requires proof of compliance with the regulations relating to abatement of asbestos prior to issuance of a demolition permit.
Federal requirements and local regulations (Regulation III, Article 4, Air Pollution Control Agency) require that an asbestos survey be conducted prior to beginning work on most renovations and on all demolition projects. This required survey must be posted at the work site. The Puget Sound Clean Air Agency also requires a Not ice of Intent to Perform a Demolition be filed with the Clean Air Agency before any demolition project may be started. If any asbestos is identified in the work area, it must either be properly abated prior to any work in the area, or not disturbed by the renovation or demolition activities. All asbestos must be properly removed in compliance with the regulations prior to any full demolition of a structure.


Mercer Island Backflow Program

The City of Mercer Island Utility Department is responsible for protecting you from contaminated water. Customer responsibilities for the continued success of this program include obtaining the proper permits for plumbing changes (including new irrigation installation) and receiving inspections of the backflow assembly installation.

After the initial installation and test by the City, the customer is then responsible for annual testing of the backflow assembly by a certified backflow tester. The City maintains a database of the water or irrigation systems that have backflow devices. As required by State law, an annual letter will be distributed requesting an inspection of the backflow device. The annual Test Report form and a link to the State certified backflow testers are provided below.
