How to clean a rainwater tank – more than just sludge removal
When we are called out to clean a rainwater tank, the first step is always to thoroughly inspect the rainwater harvesting system to identify any potential issues which may have led to degradation of the quality of the captured and/or stored water and to recommend any system improvements to alleviate future issues.
Not to say we always find issues. Most tank owners are confident maintaining their rainwater systems and call us out when they have noticed a sediment build-up, indicating that it is time for a tank clean (about every 2-3 years as a rule).
One common misconception to note: to clean a water tank, it does not have to be empty. We prefer if there is some water in the bottom of the tank (the amount varies depending on the capacity of the tank) or we can clean the tank when it is full. Our cleaning process operates with minimal water loss under normal circumstances.
If the tank is already empty, we can still clean it. But if you know your tank requires cleaning, don’t wait until it is completely empty. Best to have the tank clean and ready for the next rainfall capture.
The basic process of how to clean a water tank involves:
- Removal of the sludge layer from the bottom of the tank
- Filtering the remaining water to removed suspended particles
- Sanitising the water using a non-chlorine food-grade water disinfectant
Full details can be found on our tank cleaning page.
And of course, our tank cleaning service also includes inspection and advice or just a chance to talk over any queries you have about your rainwater system or water filtration options.
Our view is that it is equally important to help the customer better understand their entire rainwater harvesting system to eliminate future problems and increase efficiency as it is to clean the tank.
