Site work for a water / sewer project in Sunnyvale, California. Completed plans call for site work for a water / sewer project.

This project will refurbish one 5.0 MG storage tank at Wolfe-Evelyn. A structural and coating evaluation study performed in 2014 found the tank to be in poor condition. Comprehensive tank refurbishment may include interior recoating, cathodic protection improvements, foundation seismic restrainers, flex coupling adapters, repairs to the overflow moat, and other necessary improvements. In addition, improvements identified by the State Water Resources Control Board are exterior recoating of the San Lucar tank, fall protection systems at 9 tanks, and modifications of roof vents at 8 storage facilities. The fall protection systems will include the redesign or the elimination of vertical access ladders to be replaced with spiral staircases around all the tanks. The staircases, roof vents along with the Wolfe-Evelyn tank recoating will be designed in FY 2020/21. Project construction will be scheduled in 2022. Refurbishing tanks is more cost-efficient than replacement. Proper coating should keep the tanks in useable condition for up to 40 additional years. Wolfe-Evelyn tank is used to store San Francisco Public Utilities Commission (SFPUC) water to be used during peak days demands or in the event of a fire. Construction activities are usually limited to the winter months when water demand is lowest. Project is included in the City of Sunnyvale's FY 2021-2041 CIP.
