SUMMARY
As part of the Council Adopted Strategic Roadmap to improve utilities infrastructure, the City aims to upgrade the sewer collection system by replacing three to four miles of pipeline annually and the water distribution system by replacing four to six miles of pipeline annually. The goal is to improve the capacity and maintain the operability of the sewer collection and water distribution system, prevent sanitary sewer overflows, and provide adequate fire flows.
One service agreement is recommended for both the Sewer and Water Line Improvement Projects for design efficiencies and economies of scale. The Sewer Line Improvement Project involves repairing, rehabilitating, replacing, rechanneling, and installing approximately 3.5 miles of sewer line segments, manholes, and appurtenances throughout the City. The sewer line locations were selected by staff for a variety of reasons including being undersized, condition, having exceeded service life, and frequency of maintenance and high possibility of overflows. The Water Line Improvement Project involves replacing and improving approximately five miles of water mains and appurtenances throughout the City. The water line locations were selected by staff for a variety of reasons including being undersized, having exceeded service life, frequency of breaks, and/or upgrades needed for supply reliability and fire flow improvements.
