Our Rainwater Tank Installation Services Include

Installing a rainwater tank offers a multitude of benefits, making it a practical addition for homeowners and businesses alike. Firstly, it provides an eco-friendly solution for water conservation, allowing for the collection and reuse of rainwater for gardening, flushing toilets, and other non-potable uses, significantly reducing reliance on municipal water supplies. This can lead to substantial savings on water bills. Additionally, rainwater harvesting systems can play a crucial role in stormwater management, reducing runoff and the risk of flooding in heavy rain events. By mitigating the demand on municipal systems during peak periods, these tanks contribute to the sustainability of water resources. 

In areas prone to drought, rainwater tanks offer a valuable backup water source, enhancing water security. For properties located in remote or rural areas, where access to centralised water sources might be limited or non-existent, rainwater harvesting provides a vital, independent water supply.

Why Install A Rainwater Tank?

Factors To Consider When Selecting A Rainwater Tank

Every square metre of your roof can yield one litre of water for every millimetre of rainfall it receives. To optimise your water harvesting, it's crucial to direct as much roof runoff into your tank as possible. With this in mind, to select the right water tank for your needs, consider the following factors:

  • Capacity Needs: Assess your water usage by considering the size of your property, the number of occupants, and specific uses like irrigation, household consumption, or livestock. This will help you determine the size of the tank you need.

  • Space: Evaluate the space where you plan to install the tank. Above-ground tanks are easier to install and maintain but take up more space. Underground tanks save space but are more costly to install and maintain.

  • Select a Tank Shape: Tanks come in various shapes, including round, slimline, and modular. Your choice will depend on your space availability, aesthetic preference, and installation location.

  • Tank Location: The placement of your water tank can affect its efficiency and ease of use. Tanks should be placed in a position that increases rainwater catchment from roof downpipes and reduces the distance to areas of use to reduce pumping requirements.

Rainwater Tank Installation Cost

The cost of installing a rainwater harvesting system in New Zealand can vary widely based on the system's complexity, size, and materials used. For a basic setup, homeowners might spend as little as $200 - $300 for a simple rain barrel system. More comprehensive systems, including tanks, filtration, conveyance, and installation, can range from $3,000 to over $10,000. High-end systems, especially those designed for large properties or commercial use, may exceed these figures. 


It's important to note that specific costs will depend on factors such as the tank's material (polyethylene, steel, or concrete), the need for underground installation, and additional features like water filtration or advanced conveyance systems.
