What maintenance is required for a rainwater catchment system?

Inspecting the Collection Surface

Inspect the roof or collection surface of your rainwater catchment system regularly for signs of wear, damage, or debris accumulation. Clean or replace the surface as needed, ideally every 5 years for asphalt shingles and every 10 years for metal roofs. Remove any debris, branches, or leaves that could contaminate the water.

First Flush Device Maintenance

Your first flush device is designed to divert the initial flow of water from the roof to the drain, carrying potential contaminants with it. Check the device every 6-12 months to ensure it’s functioning correctly and clean any debris that may have accumulated. Replace the device every 5 years or as recommended by the manufacturer.

Storage Tank Maintenance

Regularly inspect your storage tank for signs of leaks, corrosion, or contamination. Check the tank’s integrity every 5 years and perform maintenance tasks such as cleaning the tank and inspecting the overflow valve. Consider replacing the tank every 10-15 years or as recommended by the manufacturer.
