We have a full range of Accessories to add to your water tank(s) including:
Big Water Tanks 30,000 litre Water tanks are strong, with a simple design to optimise the most strength, we have the heaviest shot weight of any standard 30,0000 litre water tank on the New Zealand Market
our Dome has the most curve on the market, that combined with the heaviest shot weight, makes this dome fully self supporting, without the need for a frame to support it.
Please note that while we have developed the strongest dome, the tank still needs to be vented, suction from a pump can cause any dome to collapse if the air cannot move.
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
Our tanks have no corrugations or indentations, the reason for this is streth.
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 700 mm we recommend that you give us a call to discuss your specific situation.
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 Water tank can store 30000L of water this with a minimum rainfall of 30mm for 3 months on a 150m² roof is:
30,000L if full + 30 x 3 x 150 = 43,500L for 90 days of bad weather
60,000if full + 30 x 3 x 150 = 73,500L for 90 days of bad weather
As a basic rule 1 tank for up to 3 people and 2 tanks for 4-6 people, larger installations of three tanks only help if there is adequate roof collection area
