The Dublin San Ramon Services District is recommending that businesses clean and flush their water systems before reopening after lengthy closures because of the COVID-19 pandemic.
The district notes that the water provided by the Zone 7 Water Agency is disinfected, but not sterile. During long-term closures, the water left in pipes, water heaters and storage tanks can stagnant as the disinfecting chlorine dissipates, allowing pathogenic microorganisms to multiply.
Thoroughly flushing water systems is especially important for schools, gyms, hotels, factories, large buildings and other facilities with complex water systems. should flush them thoroughly with fresh water before reopening, according to the Dublin San Ramon district.
The district also recommends disinfecting shower heads, faucets, and other plumbing fixtures, and checking temperature settings on water heaters, and ensuring that ice makers, dishwashers, cooling towers, and other plumbing components are safe.
