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.

We clean your tank thoroughly while aiming to preserve as much of your existing water as possible. Our process typically involves:
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.
Keeping your tank clean is one of the simplest, most cost-effective ways to protect your water supply and your family's health. If it's been a while since your tank was last cleaned — or you've noticed a change in your water — get in touch and we'll take care of it.

No. Our equipment lets us remove the sediment layer from the bottom of the tank while preserving most of your existing water, so you don't lose a full tank in the process.
Yes. As a bulk water delivery service, we can top up your tank with clean potable water in the same visit if needed — saving you arranging a separate delivery.
We clean poly, concrete, and steel rainwater and storage tanks, both above-ground and underground, for households and rural properties.
Most household tanks take around 1-2 hours, though larger rural tanks can take longer depending on size and sediment buildup.
