I <br /> ' <br /> ���/� �O� I� <br /> I <br /> � <br /> I <br /> I <br /> 1 <br /> � <br /> i <br /> RE: Sewer Backflow Protection � � <br /> � <br /> i <br /> Ueaz i <br /> You recently made an inquiry regazding sewer backflow protection. 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 lift their dischazge by I <br /> artificial means or install a backwater valve at the oudet. <br /> Basement azeas 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 <br /> azea as delineated on the enclosed map. � <br /> There aze two generally acceptable methods to control backup. Enclosed for your review I <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 Cedaz Street. Installation of a backwater valve requires a $27 plumbing permit. <br /> A grinder pump system requires a $30 sewer alteration permit, a $27 plumbing pemut, ! <br /> and a$35 electrical pemvt. <br /> We hcpe this correspondence will help clarify and provide guidance conceming this <br /> issue. The licensed plumber of your choice should be able to review your situation, { <br /> answer your site specific questions and install the system of your choice with the <br /> appropriate permits. + <br /> Sincerely, <br /> I <br /> Larry Crawford � <br /> Eng/Pub Svs Director i <br /> �c:ia:b���now ' <br /> � <br /> i <br /> CITY OF EVERETT• 3200 Cedar Street • Everett,WA 98201 • (425) 257-8800• Fau(425)257-8856 � <br />
