Water Tank Cleaning: Getting Prepared for Summer
Summer is coming, and for households that rely on rainwater, now is a good time to think about water tank cleaning.
Earth Sciences New Zealand (formerly NIWA) has confirmed a very strong El Niño event for spring and summer 2026/27, with El Niño expected to influence New Zealand's weather into 2027. A potentially drier summer is a good reason to make sure your water tank is clean. The last thing you want is to be dealing with a dirty tank when water is in short supply.
Why Clean Your Water Tank Before Summer?
Depending on how your water tank system is set up, low water levels can make it easier for your pump to draw in sediment and debris from the bottom of the tank. This can potentially lead to dirty water entering your household plumbing and can put strain on filters and other components of your water system.
Water tank cleaning before summer removes this accumulated material before your water level gets low.
Why Filling a Dirty Tank With Fresh Water Isn't Ideal
This summer, chances are you’ll need to purchase a delivery of fresh water.
When you pay good money for tested, treated, pure water, it’s a bit of a waste to put it on top of a whole lot of sludge. It turns to pea-soup straight away, and can take days to properly settle.
Suspended sediment caused by filling an unclean water tank can compromise your pump and filter systems.
A water tank cleaning before a water delivery is a good idea. If you know you're likely to need a water delivery this summer, arranging water tank cleaning beforehand can help you get more value from that fresh water.
Basic Clean or Full Clean?
Not every tank needs the same level of cleaning.
At Northern Tank Cleaning, we offer two water tank cleaning options depending on the condition of your tank.
Basic Clean
Our Basic Clean is designed for routine maintenance. We use our powerful vacuum system to remove accumulated sediment, organic matter and debris from the bottom of your tank.
It's a great option if your tank is overdue for a clean but hasn't experienced a significant contamination event.
Full Clean
Our Full Clean is recommended when a tank requires a more thorough clean, particularly following significant contamination, or when the tank is particularly dirty.
If you're unsure which option is right for your tank, get in touch and we can discuss the best approach.
Don't Wait Until Your Tank Is Nearly Empty
If you're relying on tank water this summer, water tank cleaning is one of those jobs that's better done before you desperately need it.
It also means that if you do need to purchase fresh water during a dry spell, you're putting it into a tank that has already been cleaned.
Northern Tank Cleaning is locally owned and operated in Rodney, servicing North Auckland.
Whether your tank needs a routine Basic Clean or a more thorough Full Clean, getting your water tank cleaning done before summer can help you start the dry season with a cleaner tank and a better-prepared water supply.
