Project Update - August 2021

Contractor continued to install 8-inch water main between 564 Block of El Camino Real and Middle Road, lateral service connections, and fire hydrants along the water main line. Leak test will be performed along these segments as soon as the installation of the service laterals and fire hydrants are completed and accepted by the District. Temporary 6-inch waterline will be installed after the completed segment are tied into the existing waterline at Ruth Avenue and operational.

To date, about 55% of the contract work items have been completed, project completion date is estimated to be November 5, 2021, barring unforeseen circumstances and extensive inclement weather. The construction management team along with the Contractor continued to notify residents and local businesses along the pipe alignment of work activities that may impact access to their properties during the month. Notification flyers are continuously passed out to the residents.

Project Background

In 2014, as part of its long-term strategic planning, the Mid-Peninsula Water District (MPWD) undertook a comprehensive review and assessment of its water system infrastructure and facilities. The goal was to develop a comprehensive, prioritized Capital Improvement Program (CIP) and a functional hydraulic model to modernize the water delivery infrastructure. Following development and calibration of the hydraulic model in late 2015, the MPWD generated a comprehensive list of 92 projects estimated at approximately $52 million (2015 dollars). In May, 2016, the MPWD adopted the Comprehensive System Analysis and Capital Improvement Program FY 2016-2017 Update in addition to authorizing a 5-year funding plan of $20 million. Improvements to the water main underneath El Camino Real were identified as a top-20 priority project.

The MPWD’s El Camino Real Water Main Improvements consists of replacing approximately 3,600 linear feet of 8-inch cast iron (CI) water main constructed in the 1950s that scored high for replacement in the MPWD’s Capital Improvement Program with 8-inch ductile iron (DI) along the southbound El Camino Real between Ruth Avenue and Middle Road, and abandoning a separate 300-foot section in front of Safeway. The project includes installation of pipe, fittings, gate valves, fire hydrants, new copper domestic service laterals, and reconnection of fire services to the new water main. Although a large portion of construction work will take place during the daytime on weekdays, a portion of work is scheduled to take place overnight from 9:00 pm to 5:00 am (Sunday night to Friday morning; NO work on Friday night and all of Saturday) in order to minimize inconvenience during the day to affected businesses.
