Keeping tanks clean will help maintain water quality and decrease operating costs. Removing sediment and the invisible biofilm will decrease disinfectant consumption and elevated TTHM levels.
STS provides numerous routine maintenance & cleaning services to keep your tanks in peak operating condition:
• Pressure wash to ensure clean tank interior
• Removal of bottom sediment and minerals on tank walls
• Chemical washout to eliminate invisible biofilm build up from tank interior
• Tank disinfection and return to service in compliance with AWWA standards
Tank cleaning and routine service can be included in our Annual Maintenance Program which makes tank upkeep hassle free.
