Cisterns, rooftop tanks and buried reservoirs accumulate sediment, biofilm and bacterial colonies over time. The EPA and CDC recommend cleaning and disinfecting potable water storage at least annually — more often for high-use facilities.
Our certified technicians perform mechanical cleaning, chlorine shock disinfection following AWWA C652 standards, and post-service bacteriological sampling by an independent state-certified lab.
Legionella, E. coli and coliform bacteria thrive in stagnant water and biofilm on tank walls.
Iron, manganese and calcium deposits reduce tank capacity and clog downstream fixtures.
Insects and small rodents can enter tanks through failed vents or hatches — a common finding during our inspections.
Taste, odor and turbidity issues almost always trace back to an overdue tank cleaning.
Regulated facilities can face citations and shutdowns for undocumented potable-water maintenance.
Corrosion accelerates in poorly maintained tanks, shortening the lifespan of pumps and piping.
