Water Tank Cleaning  Sunshine Coast

Water Tank Cleaning Sunshine Coast

Professional rainwater and storage tank cleaning to keep your water clean, safe and sediment-free.

Over time, every water tank collects sediment, sludge, leaf litter, and organic buildup at the bottom - and that gradually affects the quality of the water you're drinking, cooking with, and washing in. Old Mates Water provides professional tank cleaning across the Sunshine Coast, clearing out the muck so your tank holds clean, healthy water the way it should. Whether it's a household rainwater tank or a large rural storage tank, we'll get it sorted.

Why Clean Your Water Tank?

Rainwater tanks aren't "set and forget." Even with a good first-flush system and mesh screens, fine sediment, dust, bird droppings, leaves, and organic matter make their way in and settle at the base. Left alone, this builds into a layer of sludge that can:

  • Affect the taste, smell, and clarity of your water
  • Harbour bacteria and encourage algae growth
  • Clog pumps, filters, and outlets
  • Reduce the effective storage capacity of your tank
  • Contaminate an otherwise clean water supply, especially as levels drop

Health authorities generally recommend rainwater tanks be inspected regularly and cleaned when sediment builds up - typically every 2 years, though it depends on your surroundings, tree cover, and how well your tank is screened.

Our Tank Cleaning Service

We clean your tank thoroughly while aiming to preserve as much of your existing water as possible. Our process typically involves:

  • Inspection : checking the condition of your tank, water level, and the extent of sediment buildup
  • Sediment removal : clearing sludge, silt and debris from the base of the tank. We use specialised vacuum equipment that removes the sediment layer without fully draining the tank
  • Cleaning: removing algae, biofilm, and buildup from the tank walls and floor
  • Final check: making sure your tank is left clean and ready to keep storing quality water

Need a Top-Up After Cleaning?

Because we're also a bulk water delivery service, we can refill your tank with clean potable water in the same visit if your levels are low after cleaning. It's one call, one team, and one job done - no chasing a separate supplier to get your water back up.
