With many drainage systems constructed pre the 1960's they are now creaking under the population growth in our cities. Most councils now require developments and house renovations to have detention tanks. A stormwater detention tank 'detains' or slows the release of stormwater from your property and particularly your roof through the provision of an on-site water tank.






Tanksalot® water tanks are stylish, discreet and work well in restricted areas within the New Zealand urban and rural environments.



Tanksalot® Slimline Tanks give you the freedom to select the width, length and height to suit your space.


The traditional Tanksalot® corrugated round water tank is an iconic choice when space permits.

Stainless Steel

Tanksalot® Stainless Water Tanks are made from Marine Grade 316, are fire resistant and have a lifetime guarantee.

Garden Beds

Tanksalot® raised garden beds provide a convenient and elegant solution to creating a new landscaping feature.




Along with a great working relationship with Local Councils, Tanksalot® maintain a portfolio of happy clients also.

  • I wholeheartedly acclaim Tanksalot for their service and their product. My new tank sits proudly in the back garden as if it’s always been there – and is already saving me money and paying itself back. It feeds water into my toilet and washing machine, as well as being very useful in the garden. This company should win medals for customer and product satisfaction. Thanks a lot Tanksalot!

  • When renovating our Devonport Villa the City Council required us to install a water tank. We were horrified at the thought of a big round plastic blob in our back yard. Tanksalot had a great range of slim-line 3,000L tanks which matched our existing weather-board colour. Many of our friends have commented on its aesthetics as the corrugated iron complements the corrugated roof – you barely know it’s there!
