Walnut Tank 2 Repair and Recoat - CP76300027

Site work for a water / sewer project in Simi Valley, California. Conceptual plans call for site work for a water / sewer project. This project would recoat the interior of the 2 Million gallon capacity Walnut Tank No 2 The tank was constructed in 1992 and the interior was last patch repaired in 2001. A dive inspection conducted by CSI Services in 2011 identified that the tanks interior original coating had deteriorated. Tank longevity is significantly improved, cost effectively by recoating. In addition, the Waterworks Facilities Assessment conducted by Carollo Engineers in 2015 recommended to replace the cathodic protection system which has been in service for 26 years. A Seismic Evaluation completed by Kenndy Jenks in January 2021 recommends to lower the overflow inlet by 3 feet to lower the seismic hoop tensile stress on the lowest shell ring and raise the tank roof by 4 feet to increase freeboard to prevent damage to the roof and shell during an earthquake. Additional funding in the amount of 400,000 is estimated for the seismic mitigation. Design to be completed in July 2022 and construction expected to be completed in January 2023. Project is included in the City of Simi Valley's FY 2022 - 2027 CIP. Per the owner, as of July 13, 2022, the design for this project is being done in-house. A timeline for construction has not been determined. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
