Everything you need for your new home's rainwater, greywater, and wastewater systems.
Enjoy the convenience of one custom-designed package and a single quote for all systems.
We can supply all the equipment you'll need to your plumber or drainlayer. We also advise on rainwater and greywater systems and design and install wastewater systems.
Rainwater harvesting is a simple and cost-effective way to collect and store water. In most cases you can easily divert your existing downpipes to fill one or more water storage tanks to help save money and make the most of a precious resource.
We will work out what you need and supply all the equipment for a rainwater harvesting system. Choose above or below ground storage tanks sized from 500L to 30,000L, screens that prevent debris from entering the water storage tank, and water purification treatments.
All large pre-ordered water tanks are delivered free to your home build. Some can be installed yourself, while others will require professional installation.
Pumping and filtration
Once you have collected your rainwater, it needs to be filtered and pumped into your home. We'll figure out the right pump and pair it with a sophisticated filtration system. A UV steriliser kills 99% of bacteria and parasites with ultraviolet technology, which is eco-friendly and chemical-free. Next, scale, sediment, and rust, if necessary, are removed down to 1 micron. Then, water is ready for drinking and household use.
Household greywater can be filtered to nourish your lawn and gardens using the Watermate greywater recycling unit.
The Watermate uses a simple but effective three stage filtering process to remove impurities such as hair, lint, soap and detergents, and the resulting water is ready for the garden.
If you're on a septic system, sending your greywater out for garden use keeps it out of your septic system, reducing the amount of soap and chemicals that can negatively affect its bacterial performance.
The best residential wastewater systems in New Zealand are only found at Allflow. You can opt in for a pump chamber to send the treated water to irrigation or a disposal soak field.
We offer low-maintenance systems that easily meet and often exceed Council standards. They are designed to run on very low energy or solar power – ideal for new energy-efficient homes. Compact and concealed, our systems offer easy access and integrate with your garden. Quick install means it can take just one day for the heavy duty work.
The Allflow team has decades of experience in wastewater design and installation. We can design and install the entire system ourselves, which includes securing all necessary consents. Or if you have drainlayers on your new build team, we're happy to advise and work with them, supplying all the necessary equipment.
