Rainwater Harvesting
Collect and filter rainwater from your own roof to cut mains water costs — a typical household can harvest around 100,000 litres a year.
How it works
Rainwater is collected from your gutters and channelled down into a filtered storage tank, where the filtration system removes dirt and debris before the water is stored. From there it's piped either into the house — for toilets and washing machines — or out to external taps for the garden and washing the car.
Systems can be fitted in both new builds and existing homes. Tanks can sit above ground, though most installations bury the tank underground out of sight, with gutters and rainwater drains re-routed to feed it directly.
What you can use harvested rainwater for

- Washing machines
- Garden watering

Around 100,000 litres per household
The exact amount you collect depends on local rainfall and the angle of your roof, but the average Irish household can expect to harvest in the region of 100,000 litres a year — with commercial buildings and their larger, sloped roofs collecting considerably more.
