Why Water Tank Cleaning is Important in New Zealand

Clean water is essential for maintaining good health, and contaminated water can cause a range of illnesses. In New Zealand, waterborne diseases such as giardia, cryptosporidium, and campylobacter are common, and they can be particularly dangerous for young children, the elderly, and people with weakened immune systems. Contaminated water can also lead to outbreaks of diseases such as leptospirosis, which can be fatal.

There are several factors that can contribute to water tank contamination in New Zealand, including animal and bird droppings, leaves, debris, and algae. In addition, if the water tank is not cleaned and maintained regularly, it can become a breeding ground for bacteria and other harmful organisms. This is why regular water tank cleaning is so important for ensuring that the water remains safe and healthy.

How to Clean Your Water Tank Effectively

Cleaning your water tank can seem like a daunting task, but it’s essential for maintaining the quality of your water supply. The first step is to drain the tank and remove any debris, such as leaves or twigs, from the bottom of the tank. Then, you can use a high-pressure hose or a scrubbing brush to clean the sides of the tank. It’s important to use a cleaning solution that is safe for use with potable water, such as a mixture of vinegar and water.

After cleaning the tank, it’s important to disinfect it to kill any remaining bacteria or other harmful organisms. You can use a chlorine solution to disinfect the tank, following the manufacturer’s instructions for the correct dilution and contact time. Alternatively, you can use a UV treatment system to disinfect the water as it flows into your home or business.

How Often Should You Clean Your Water Tank in New Zealand?

The frequency of water tank cleaning depends on several factors, including the size of the tank, the amount of water used, and the quality of the water source. As a general rule, it’s recommended that you clean your water tank at least once a year, and more frequently if you notice any signs of contamination, such as a foul smell or discolored water.

Maintaining Your Clean Water Tank

Regular maintenance is key to ensuring that your water tank remains clean and in good working order. This includes inspecting the tank regularly for signs of damage, such as cracks or leaks, and repairing any issues promptly. It’s also important to keep the area around the tank clear of debris, and to ensure that the tank is properly sealed to prevent contamination.


Water tank cleaning is an essential part of ensuring that your water supply remains safe and healthy. By following these tips and guidelines, you can help to prevent waterborne diseases and other health problems. Remember to clean your water tank regularly, disinfect it thoroughly, and maintain it properly to ensure that your water remains clean and safe for consumption.
