Harvest rainwater.
Like never before.

Reduce water consumption in homes with rainwater harvesting. The average household consumes thousands of litres of potable water annually, which can be replaced with collected rainwater. Simply store rainwater in tanks and use a pump to feed it into the household water supply for non-potable needs, reducing reliance on mains water.

Benefits for households and the environment

Harvesting rainwater is a much more sustainable approach to using water in domestic settings, especially for communities that rely on imported water or are governed by regulations regarding water use. Few countries have legislation on the national level, but trends show support for the utilisation of rainwater harvesting as climate change makes the weather more unstable and extreme.

Furthermore, water is becoming a scarcer resource, and politicians see more potential in harvesting rainwater to protect it, moving it up on the agenda.

A rainwater harvesting system can benefit households and the environment by:

Encourages water conservation

Reduces reliance on groundwater and surface water bodies to conserve natural water sources, crucial in water-scarce regions.

Diversifies water sources

Relieves pressure on mains water and promoting self-sufficiency with an extra water source, especially in areas with limited and unreliable piped water access.

Lowers household expenses

Replaces potable water for laundry, garden watering, flushing, and other non-potable tasks. Since rainwater is a natural resource it is free, and can reduce household water bills.

Reduces governmental spending

Lowers the reliance on centralised water networks, which reduces government investments in water infrastructure projects and frees up funds for other social and economic priorities.

Supports environmental protection

Lowers stormwater runoff volume and speed, which prevents erosion, flooding and pollution in rivers and lakes – and promotes sustainable urban management.

Drives energy and resource efficiency

Reduces the need for water extraction, treatment and transport, which lowers energy and resource waste and protects natural ecosystems.
