The testing locates defects and improper connections that <br /> allow storm ater runoff and groundwater to enter the public wastewater collection system. A <br /> secondary oal of this pilot project will be to assess the effectiveness of the methods and <br /> materials of recent collection system improvements. Also, smoke testing results wilt provide <br /> i <br /> some insig s into the conditions of private building service lines, which are the lines that <br /> ~ connect ho es and businesses to the public system. <br /> This year's testing includes portions of the wastewater collection system in the Friendly, <br /> Amazon, S utheast, Jefferson Westside, and Fairmount neighborhoods. Testing will begin in <br /> the area of 6`h Avenue and Tyler Street and is expected to take several months to complete. <br /> Duri g the tests, which are endorsed by the U.S. Environmental Protection Agency, <br /> nontoxic, w ite smoke is released into sanitary sewer lines to identify problems. Residents are <br /> notified bef re testing begins in their neighborhood. The smoke will not harm plants or animals <br /> and will qui kly dissipate leaving no residue or stains. <br /> Aft r smoke is blown into a sewer line, crew members watch for tell-tale signs of <br /> deteriorate lines or improper connections. White smoke rising from the ground generally <br /> indicates a rack or other defect in a sewer line. Smoke coming from a roof gutter, downspout or <br /> <br /> i <br /> area drain i dicates that a storm drain is improperly connected to the wastewater collection <br /> system. <br /> (MORE) <br /> Publi Works • Administration • City of Eugene • 858 Pearl Street .Eugene, OR 97401 <br /> Phone: (541)682-5262 • FAX: (541) 682-6826 • www.ci.eugene.or.us <br /> <br />
