Rainwater tank cleaning: when it’s needed and what a proper clean looks like

Rainwater tanks can run for years without issues — until sediment, organic matter, or algae starts to build up. A proper clean is about keeping water quality high and protecting pumps/filters.

Signs your tank may need cleaning

  • Water has a noticeable smell or taste
  • Sediment shows up in filters or fixtures
  • Pump cycles more often than usual
  • Recent roof work, storms, or heavy leaf fall

What’s involved in a tank clean?

  • Inspection of tank, inlet screens, and overflow
  • Removing settled sludge/sediment from the base
  • Cleaning/servicing filters where fitted
  • Checking pump intake and basic function

How often?

It depends on your roof catchment, first-flush system, and filters. A simple rule: if you rely on tank water, schedule an inspection and clean when you notice quality changes — or every few years as preventative maintenance.

For an accurate quote, we’ll need tank size, access, and a couple of photos.
