The Everett � <br /> Municipal Code requires all basements with drains or sewers where there exists the ! <br /> unusual danger of "backup" from the public sewer system to !ift their dischazge by + <br /> artificial means or install a backwater valve at the oudet. � <br /> Basement areas susceptible to backup aze typically those spaces whose floor elevation is � <br /> below the elevation of the abutting street or alley and located within the combined sewer I <br /> area as delineated on the enclosed map. <br /> There aze two generally acceptable methods to control backup. Enclosed for your review <br /> is information conceming the backwater valve and grinder pump systems. Both systems <br /> require maintenance by the homeowner with the backwater valve probably requiring more <br /> maintenance than the grinder pump system. Both installations require that a permit be <br /> obtained from the Public Works Department service counter located on the second floor <br /> at 3200 Cedar Strcet. Installation of a backwate� �•alve requires a S27 plumbing permit. <br /> A grinder pump system requires a S30 sewer alt�,adon pemut, a $27 plumbing permit, ' <br /> and a$35 electrical permit. �� <br /> We hope this correspondence will help clarify and provide guidance conceming this � <br /> issue. The licensed plumber of your choice should be able to review yo•.0 situation, <br /> answer your site specific questi�ns and install the system of your choice with the , <br /> appropriate permits. <br /> Sincerely, � <br /> ; <br /> Larry Crawford � <br /> Eng/Pub 3vs Director � <br /> �c:�a:n��know <br /> CITY OF EVERETT• 3200 Cedar Street • Everett.WA 98201 • (425)257-8600• Fax (425) 257-8856 <br />
