RESIDENTIAL RAINWATER HARVESTING

Considerations depend on the type of property you have, how you plan to use the water and the type of tanks you use.

Considerations for underground rainwater harvesting

To supply water for use in your home, an underground tank is usually needed to store enough water to meet your household’s needs. Before installation, there are a few important factors to think about:

• Can a digger reach the spot where the tank will go?

• Are there any pipes, cables, or other utilities where the tank will be installed?

• Will excavation be limited to soil, or will hard surfaces like concrete need to be removed?

• Will cranes, concrete and muckaway vehicles be able to reach the area where the tank will be installed?

• Do you need to drive or park over the tank later, like on a driveway?

Considerations for above-ground tanks/water butts

Typically water butts and wall tanks are more suitable for supplying water for gardens and not in the home, though if space permits, a larger above-ground tank can be used. Some key considerations include:

• Is there a spot near your downpipes that looks good and works visually? Downpipes can sometimes be moved, but it requires careful planning to maintain proper water flow and prevent leaks and water damage.

• If placing the tank in the rear garden, are there any pathways or tight spaces to consider? For example, if a pathway is only 1 m wide, the tank should be no wider than 1 m

• Will you require a pump? i.e. if you are planning to supply irrigation systems, sprinklers or hoses.

The easiest way to start is by sending us the measurements of your roof area and some photos of the site, by email or Whatsapp.

If possible, a quick video call also helps us understand any specific considerations. From there, we can arrange a site visit to take measurements and provide you with an accurate quote.

The simplest way to estimate your rainwater harvesting potential is to multiply your roof area by the average annual rainfall in your location.

You can also use our handy rainwater harvesting calculator, which will suggest the recommended tank capacity to maximise your potential.

When space is limited or you'd prefer a hidden option, our slimline baffled tanks a great solution. They fit perfectly in garages and walkways, can be linked together and store between 400L and 1000L, perfect for supplying gardens and smaller irrigation systems.

Most above-ground rainwater harvesting systems can be expanded later by linking additional tanks. Many of our customers choose to add more tanks as their needs grow.

Underground systems can also be expanded, but doing so usually involves more extensive work.

Rainwater can be used throughout the home and garden for non-potable purposes, including:

- Watering plants and flowers

- Supplying water to irrigation and sprinkler systems

- Toilet flushing, washing machines, outdoor cleaning, pressure washing

For tanks that supply the home or irrigation/sprinkler systems, a mains water top-up is included. This ensures you’ll always have a reliable water supply, even if the tank runs low.
