We have a full range of Accessories to add to your water tank(s) including:
Big Water Tanks 300l - 10,000l plastic water tanks are heavy duty and built to last. If you compare them to other products you'll see the difference in weight and thickness, this makes them renowned for their strength and quality. The tanks are supplied with tie down eyelets to make them easy to install and secure once in place.
Proven ridging design on the top prevents the possibility of sagging.
The turreted manhole is situated on the edge of the tank to allow for easy inspection, cleaning and installation of inlets and ball valves if required.
Our Plastic is manufactured here in New Zealand to an incredibly high NZ AUS Standard and is suitable for potable water
Our plastic resin has been specifically designed as a large tank grade material with the best UV Stabilisation available
The plastic resin complies with Australian food contact requirements (AS2070:1,8) and potable rinking) water standard AS4020
Our tanks have no corrugations or indentations, the reason for this is strength.
We Believe that the corrugations create a weaker tank because they allow for more movement like an accordion in a vertical direction creating small stresses at each corrugation
In the process of rotational moulding corrugations are thinner on the convex curves and thicker on the concave creating an uneven wall thickness through the tank,
The larger surface area of a corrugated tank means that with the same amount of plastic the effective wall thickness is reduced
Please use the checkout procedure for estimates on freight, we reserve the right to cancel an order if freight is incorrectly calculated by our website, our site cannot calculate some rural areas or island deliveries, we will contact you if there is an issue with a freight costing to your location.
We Deliver Water Tanks throughout the North of North Island, Our rates are based on distance, that makes us a bit more expensive fo"far away" deliveries we can arrange freight to most islands, please call us or contact us with your address and details we can confirm the price for the delivery
Our Delivery prices are subject to our approval and are to the "gate", however we will normally assist putting the tank into its final location if it is safe for us to do so and our vehicles can make the trip, sometimes a digger or crane is required in hard to reach locations
Please notify us of any known obstacles, low bridges low power lines or narrow roads... en route to your property we can decide how to accommodate your delivery before we leave.
Tanks are Pushed off the drivers side of the trailer and land on the base of the tank in a safe location, the tank can be pushed, dragged or lifted into the final installation location.
A buried tank needs careful consideration and every situation is a little different, while our tanks are strong enough to be buried up to 500 mm we recommend that you give us a call to discuss your specific situation (Note: Tanks Smaller than 1,000l may NOT be buried).
Tanks like swimming pools can pop up out of the ground if there is no water in them, if a tap in the house is left on in the middle of winter when the ground is very damp, if the tank empties the buoyancy is huge it will lift out the ground and will break connection pipes and mean the tank would need to be reinstalled...
As a simple guide you cannot bury a tank deeper than the lowest part of your section or natural drainage with a 1:100 fall. So if you have a flat site or section with no falls or that is very flat, burying the tank is not recommended or covered by our warranty in the event of uplift.

Lets keep this simp"ish" because there are a large number of factors that increase or decrease water usage....
An average house is 200m² with an average rainfall of 1200mm thats 240,000 L rainfall a year
If you collect all your water (none overflows) that the following per person per year:
The New Zealand water usage average is about 200L per person per day (this is an average not conservative country living...)
In Summer months the average north island water fall is as low as 72mm / month, this can be as low as 10-20mm per month in bad months...
Our small Water tank range can store up to 10,000L of water this with a minimum rainfall of 30mm for 3 months on a 150m² roof is:
5,000L if full + 30 x 3 x 150 = 18,500L for 90 days of bad weather
10,000L if full + 30 x 3 x 150 = 23,500L for 90 days of bad weather
As a basic rule 1 10,000L tank for up to 1 person and 2 10,000L tanks for 2 people
