PGCSD Water Storage Tank

Project to replace 3 existing bolted steel tanks.  The old 425,000-gallon tank had been offline since suffering vacuum collapse in 2016 and the other two bolted tanks were leaking and beyond their serviceable lifetime.  To maintain the potential for the addition of future storage at the District’s only and best tank site, the design replaced the three old tanks with a single 500,000-gallon welded steel tank and replaced and reconfigured all site piping.  Design and construction challenges included a small site with difficult access through a single steep driveway, working around the two old tanks that needed to remain in service until the new tank and piping were online and reconnecting to the existing water distribution system with the old tanks in service.  Bailey Civil Engineering completed the project civil engineering design, construction plans and specifications, project management, construction management and the majority of inspection with sub-consultants completing the survey, environmental and geotechnical work, and coating inspection.  The Project’s civil engineering design was completed in 2017 and 2018 and the Project was bid in 2020 with construction complete in October 2021.
