Document Description
The City proposes to upgrade the existing sewer and stormwater infrastructure at the former wastewater treatment plant located southeast of the Chico Regional Airport and adjacent to the City Compost Facility on the west side of Cohasset Road. The purpose of the project is to prevent the discharge of overflow wastewater into an existing abandoned wastewater holding pond to avoid inadvertent mixing with stormwater runoff during rain events. Specifically, an existing storm drain line will be abandoned, capped in place, and replaced by approximately 345 feet of 12-inch storm drainpipe that will bypass the abandoned wastewater pond and discharge directly into an existing adjacent storm drain ditch. Additional work includes the installation of a new, real-time wastewater level sensor in the sewer flow control vault to provide early detection of downstream obstructions in the sewer main and follow-up maintenance response. A new sewer manhole will be installed downstream from the sewer siphon south of the Sheep Hollow levee to allow for maintenance. The existing manhole located within the channel will be abandoned in place. An all-weather, crushed rock roadway will be constructed to allow access to the manhole year-round. Construction is expected to begin in the summer of 2026 or 2027 and is anticipated to last approximately three months.
