Quick Answer
Regularly inspect and clean your rainwater collection system to ensure it remains free of debris and contaminants, and maintain the integrity of the roof catchment and storage tanks.
System Inspection and Maintenance
Inspect your rainwater collection system at least twice a year, or after any extreme weather events. Check for signs of damage, rust, or wear on pipes, fittings, and storage tanks. Ensure all connections are secure and properly sealed.
Cleaning and Disinfection
Clean the roof catchment area by hosing it down with clean water every 6 months to remove debris and contaminants. For more thorough cleaning, use a soft-bristled brush and a mild detergent. After cleaning, disinfect the system by injecting a solution of 1 quart of unscented bleach per 100 gallons of water into the storage tank. Allow the solution to circulate for 24 hours before flushing the system.
Storage Tank Maintenance
Store rainwater in a clean, well-maintained tank to prevent contamination and bacterial growth. Check the tank’s integrity by inspecting it for signs of rust, corrosion, or damage. Replace any damaged or corroded parts immediately. Consider adding a first flush device to divert the initial flow of water from the roof catchment, which may contain contaminants, before it enters the storage tank.
