Project Background

As part of MPWD’s ongoing Capital Improvement Program (CIP), a Comprehensive System Analysis was initially completed by staff and the District Engineer in 2015, and adopted by the Board for FY 2016-2017, to generate a comprehensive list of capital projects geared toward much-needed replacement and upgrade of MPWD’s water delivery infrastructure. On April 23, 2020, the Board adopted the FY 2019-2020 Update of the Comprehensive System Analysis that included a total of $80 million in prioritized, system capital improvements, and a 5-year Capital Improvement Program (ClP) for FYs 2019-2023 totaling $27,425,000 (Resolution 2020-08). Improvements to the water main underneath Old County Road were identified as a high-priority project.

The MPWD’s Old County Road Water Main Improvements consists of replacing approximately 3,200 linear feet of 4- and 8-inch cast iron (CI) and 20-inch concrete cylinder pipe (CCP) transmission line with construction dating back to the 1930s that scored high for replacement in the MPWD’s Capital Improvement Program with 8- and 20-inch polyvinyl chlorinated (PVC) pipe along Old County Road between Ralston Avenue and F Street, and a separate 450-foot section along Ralston Avenue between Old County Road and Elmer Street. The project includes demolition and abandonment of existing pipe and installation of new pipe, fittings, valves, fire hydrants, 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.

The MPWD will soon be meeting in person with business owners and residents along the construction zones to answer questions and discuss possible concerns. The MPWD will also provide regular updates to businesses and residents in the construction zones and will be available to contact directly throughout the planning and construction process.
