Tank Cleaning

Health  & Safety Aspects

Do you know what’s in your water? Rain can easily carry contaminants like pesticides, plant matter and animal droppings to the bottom of your rainwater tank where they can accumulate, rot and compromise your water quality over time.

The Bundaberg Water team uses specialised industrial systems to vacuum the water tank and remove the sediment directly. Because it doesn’t get stirred up, less water needs to be used for you to enjoy clean water again.

According to Australian Health, rainwater tanks for residential or commercial use should be inspected and cleaned at least every 3-5 years. In between tank cleanings, a good filtration system can go a long way to keeping your water supply clean and safe for you and your family to enjoy. Ask us for details/suggestions!

Sludge Removal

Solids that have entered the tank eventually get broken down, settle on the bottom and become sludge. If not cleaned regularly, this can impact on the quality of contents in the tank and clog pipes. During rain events or when the tank is filled from a truck the sludge is stirred up and infiltrates the entire piping network.  This is the most vulnerable time for people becoming sick from water bound pathogens.  Sludge also blocks filters resulting in excessive filter replacement costs.

We remove the sludge by vacuuming using a small amount of water from the tank and pumping it onto the ground. IF required we can arrange for removal off-site.

Microbial Contamination

Pathogens, including eColi, Legionella, Giardia and Cryptosporidium can proliferate inside a poorly maintained tank. All tanks are disinfected at completion using HACCP approved Ultra Sil hydrogen peroxide.


How do you clean out the tank?
We suck all the sediment from the bottom of the tank including mud, decayed vegetable matter and animal droppings.
What happens to the water and how much do you use?
The water and sediment debris is discarded onto the ground. Generally, we use about 300-400mm of water dependent on how much sediment there is to start with.
How much water needs to be in the tank before you start cleaning?
We need at least 1/3 of a tank of water so our suction hose can sit on top of the water. If you don’t have this much, we usually deliver a load of water into the tank first, wait a few days for it to settle and then clean it out.
