Rainwater Harvesting
An all-in-one system where technology does the work for you when it comes to collecting and utilising your rainwater for in-house reuse.
If your rainwater tank is running low, the roof mounted controller automatically switches the water flowing to the house from the tank to water directly from the water mains. Switching back to rainwater automatically once your tank’s water is replenished. It will always use rainwater first and you will always have an uninterrupted waterflow to your home.
These all-in-one rainwater harvesting systems come complete with a roof mounted automatic water switch, mains isolation valve, submersible pump, leaf strainer, overflow port, inspection hatch and outlet tap.
When it comes to the installation of your system, the experience and expertise of our team make it easy for you. Whether it be an addition to an existing home or during the construction phase.
So for an environmentally friendly rainwater harvesting system that supplies your appliances such as toilets and laundry with fresh rainwater, instead of mains water. Contact our friendly sales team today to help organise installation of your rainwater harvesting system.

KEY FEATURES
When it rains, your tank collects the rainwater running off your gutters and pipes. The leaf strainer filters debris and contaminants from entering your tank. The collected water is then pumped from the tank to your house via the Divertron submersible pump. If your rainwater tank is running low, the roof mounted controller automatically switches the water flowing to the house from the tank to water directly from the water mains. Switching back to rainwater automatically once your tank’s water is replenished. It will always use rainwater first and you will always have an uninterrupted waterflow to your home.
The planning stage is the ideal time to discuss your rainwater harvesting needs with your builder. This advanced planning will reduce costs by having the pipework, GPO and base for tank in place prior to installation of your rainwater harvesting package. Building Schematics and Specifications are available for your builder on request.
If you have an existing home, and would like to install rainwater harvesting system West Coast Poly’s team can help guide and assist you through the process. We also have qualified plumbers that can quote on these installations for you.
Any building with a large roof and a high demand for non-potable water can use a rainwater harvesting system to help solve environmental storm-water management issues and make substantial savings on the use of mains water. It’s why rainwater harvesting systems are increasingly being incorporated in commercial and public-sector developments such as office buildings, schools and hospitals.
Such buildings frequently have large roof areas which of themselves present storm-water management issues; collecting this roof water for re-use helps to alleviate this problem.
Conversely, buildings with multiple occupancy have a high, and potentially expensive, demand for toilet flushing water; using harvested water rainwater for this purpose therefore makes excellent sense.
Distribution centres, too, with their requirement for fleet vehicle washing are an excellent example of the cost-effective and conservation application of rainwater harvesting.
Schools and educational establishments can efficiently manage their water consumption by installing rainwater harvesting systems, reducing usage from the local mains supply and make a significant contribution to a sustainable future.
West Coast poly offers a range of rainwater harvesting systems and can offer expert advice on system specifications that will ensure the most cost-effective rainwater harvesting system is designed for their project.
