Water Tanks North Island | Water Tanks New Zealand

Known for its warm temperate climate, the North Island of New Zealand is spread over 113,729 sq/km and receives an annual rainfall average of between 920mm and 1359mm.  The harvesting of rainwater for domestic and industrial consumption is on the increase as the North Island’s population increasingly adapts to changing weather patterns.

Harvesting rain from household rooftops and storing it for drier periods provides benefits in three ways. Firstly it takes pressure of the mains water supply, secondly it reduces a user’s carbon footprint and thirdly it is a most cost effective way of reducing household bills. A polyethylene tank can provide an independent supply of water during the drier months, helping to meet the irrigation demands of a garden and household alike.

Why a poly water tank?

Rainwater is a valuable commodity which is readily harvested and stored for when it is needed most. To put this in perspective, the high altitudes of Rotorua in the northern central region receive close to 1359 mm of rain annually over 118 days. The capacity to store this amount of water provides households in the North Island with an opportunity to reduce reticulated mains consumption in a safe and hygienic way.

Polyethylene tanks are made from food grade, UV stabilised resin. Unlike other types of water tanks that may leach small amounts of zinc or lime, a polyethylene tank provides a source of clean, taint free water. The key attributes of polyethylene tanks include longevity, durability and functionality. During the manufacturing process, wall thickness is maximised at the base which provides the tank with long term structural strength and high impact resistance. Poly tanks also have the advantage of being rust and corrosion free. The availability of poly tanks in a wide variety of shapes and sizes means that even the most challenging application can be addressed. For example slimline tanks offer an ideal solution in the narrowest household space. Capacities vary and depend on annual rainfall data and volume and user requirements.

A water tank built for New Zealand’s North Island conditions.

The variable climate across the North Island means that water tanks are subject to extreme weather conditions. Polyethylene tanks are built for strength and longevity and can sustain extreme weather conditions from blistering heat to severe cold and punishingly windy environments.
