CST Water specialises in comprehensive water tank cleaning services throughout the Waikato region, catering to tanks of all sizes. Our team conducts meticulous cleaning of your tank.
Reasons to Keep Your Water Tank Clean
There are several reasons why keeping your water tank clean is of utmost importance. While the exterior appearance may seem fine, it does not guarantee the interior is free from potential hazards. By having your tank professionally cleaned, you ensure:
- No dead animals lurking inside the tank, preventing water contamination
- Sludge does not accumulate at the bottom of the tank, which can harbour harmful bacteria
- The water remains clean and free from bugs
- No underlying issues with the tank exist that could lead to leaks or water contamination
The above is especially critical using rainwater for your property’s water supply, as contaminants from the roof and gutters can quickly enter the tank


Our 5-Step Cleaning Process
At CST Water, we follow a rigorous 5-step cleaning process to ensure the highest standards:
- 1. We empty the tank by removing the water, creating an empty space for cleaning.
- 2. We vacuum the walls and bottom of the tank, removing any sludge or dirt.
- 3. We perform a thorough water blasting of the tank walls to ensure comprehensive cleaning.
- 4. We repeat the vacuuming process to eliminate any remaining debris from the tank.
- 5. We sanitise the tank with chlorine, effectively disinfecting it.
Alternatively, if you wish to retain the water in the tank, we can store 10,000 litres in a temporary bladder and refilter it back into the tank at an additional cost. Additionally, we offer the option of delivering 13,000 litres of potable water on the same day.
