2. May 18, 2012 2 What is a Sanitary Sewer Lateral? The sanitary sewer lateral is the section of pipe that connects your home to the Wentzville's sanitary sewer main. This is how your sanitary waste is carried away from your home. Wentzville

3. Reasons for a program Public Safety – Sanitary back ups in basements can lead to health issues. Environmental Concerns - A broken or clogged lateral can lead to waste water getting into our streams, and lakes. Community Stability – Inability to pay for major repair costs can lead to vacant homes or foreclosure Public System Performance – broken laterals can lead to inflow and infiltration into the public sanitary sewer system. I & I can cause back ups in basements, manholes overflows and uses up available treatment capacity. 3May 18, 2012

10. History of Sewer Laterals in Wentzville Clay tile is the most prevalent material for failing sewer laterals in the City’s system. PVC materials are the most commonly used since the early 70’s and have very few failures due to the materials. Less than 9% of the City’s 200+ miles of sewer mains are of clay tile materials. All sewer laterals in Wentzville had been 4” PVC starting in 1972 and increased in size to 6” PVC in 1989. May 18, 201210
