Water Tank Cleaning

Water tank cleaning for your home

If you rely on a rainwater collection system for the water you drink, cook and shower with, you should get your water tanks checked and cleaned by a professional regularly. The Ministry of Health advises an inspection and clean of your water tank at least once a year.

If it has been a while since your tank was last cleaned, call Happy Tanks and book in a service. We offer two levels of cleaning services for round water tanks, and service customers in Northland and Auckland, from Cape Reinga to Bombay and everywhere in between.

For cleaning your square, rectangle or other shaped concrete water tanks please call us on 0800 190 150 to discuss what options will work best for you.

What type of cleaning services are available?

Happy Tanks offers the following water tank cleaning options:

Standard Vacuum Clean

Removes 90%-99% of sediment and sludge from the bottom of the tank.
This preserves the clean water, without it being removed.
The tank needs be at least 1/3 full of water, the more water in the tank the more efficient the clean.
This clean usually takes one hour to complete. We then ask water not to be used for one to two hours to allow the water to settle.
An optional additional sanitiser can be added after which will guarantee your water is safe for household use.
An option to drain the tank on completion is also available.

Tank Deep Clean

Removes 100% of the sludge and sediment from your tank.
Two trained technicians (complying with all the health and safety regulations regarding entering a confined space) drain the tank, clean and sanitise the walls and floor, then wet and dry vacuum leaving the interior of the tank perfectly clean.
This clean is recommended when the tank has not been cleaned for 10+ years or the tank has been contaminated by something. Eg, chemicals, clay or algae bloom.
The tank is left empty in this process. We can assist with arranging local water carriers to deliver replacement water.
This clean can take up to four hours.

For square, rectangle or other shaped tanks please contact us on 0800 190 150 to discuss what cleaning options will work best for you.

Water Testing

Safe drinking water is essential for your health, your family, and anyone who visits your home. If you rely on tank water, it’s recommended to have your water tested from time to time, especially if you or someone else in your household has been feeling unwell, to make sure it is free from harmful germs and chemicals.

Contamination of a tank water supply can be caused by:

Viruses and germs (such as Cryptosporidium, Giardia, Campylobacter, Salmonella, E. Coli) from animal or bird faeces entering the source of the supply.
Bird or animal droppings on the roof, dead animals or insects in the gutters or the tank.
Leaves, soil, or other debris entering the tank.
Lead flashing on the roof causing high lead levels in the collected water.
Volcanic and wood ash, agricultural spray drift, and chemical residue from vehicle emissions.
Cracks or holes in partially buried tanks.

Regular tank cleaning should avoid these problems but if you are unsure about the quality of your water, have it tested! Happy Tanks can arrange for your water to be tested for E. Coli or heavy metals using a third party or council laboratory.

Trust Happy Tanks to keep your water tank and system safe, clean and healthy
