Tank maintenance

To help ensure the integrity of your  rainwater tank, the quality of the collected rainwater, and the safety of the community against disease, follow this simple maintenance checklist.

Monthly inspection   This should involve checking the tank strainer and tank overflow screen for any breakage where mosquitoes can enter. Clean them monthly throughout summer wet season and three monthly from Autumn to Spring.

Three monthly inspection  Check and clean first flush devices, and leaf guards on rainheads. Check the roof and clean gutters of plant material and other potential contaminates. If large amounts are found, then inspection and cleaning should be done more frequently, especially after heavy rainstorms. Prune overhanging tree branches and foliage. 

Six monthly inspection   Check tank for defects and repair.Visually check water quality; ensure water is clear and contains no unusual smells.Check for evidence of animal, bird, or insect access including mosquito larvae; if present locate and close access points. Check for algal growth; if present, find and close all sources of sunlight infiltration.Ensure all rainwater outlets have the correct signage.

Yearly  Check tank structure and base for structural integrity. Remove accumulated sediment sludge from inside the base of the tank.
