Rainwater Harvesting

Smart Rainwater Harvesting

Rainwater harvesting refers in simple terms to the capturing and storage of rain which falls on the roof of a building, usually in containers called water butts. In areas of high rainfall, the amount of rain which may be captured is vast, particularly off buildings which have roofs with large surface areas as many businesses do. In a simple system this water can then be manually taken to the areas it is required, such as for watering plants in a home.

Whilst normal rainwater harvesting systems remove large objects such as branches and leaves from the water, a smart system can offer further cleaning and far greater uses for the collected rainwater. By installing levels readers and pumps, the amount of water actually collected can be monitored, and the water can be pumped to exactly where it is required. When filtered and connected to a treatment plant, the rainwater can be used for more useful applications such as laundry and toilet flushing.

The pump can be controlled by a smart programmer, which measures the total usage in the home and can allocate the collected water to wherever it is required.


    • Very cheap to implement on a simple basis
    • Result in significant water savings and as such reduced utilities bills
    • Reduction of carbon footprint
    • Reduces the use of mains water
    • Can be installed on virtually any structure

Why should you invest in a smart rainwater harvesting system?

Smart rainwater harvesting systems have significant environmental and water-energy nexus benefits and can save you up to 50% on your water bills.

Frequently Asked Questions

How does rainwater harvesting work?

Rainwater harvesting is a technique for collecting and storing rainwater runoff from impervious surfaces.

Rainwater harvesting can be used to provide water for human consumption, irrigation, livestock and wildlife watering, washing cars and other outdoor activities.

Rainwater harvesting can also help reduce the amount of storm water runoff that enters natural waterways such as rivers and streams. This reduces the amount of pollution in these waterways which in turn improves water quality downstream.

What are the components of a rainwater harvesting system?

Rainwater harvesting is the process of collecting and storing rainwater for future use. Rainwater harvesting systems are typically made up of three basic components:

– A roof surface that can be sloped to collect water

– A storage tank to store the harvested water

– An overflow pipe that diverts excess water from the tank back to the atmosphere

What are the different types of rainwater harvesting systems?

There are many different types of rainwater harvesting systems that can be installed depending on the location and the amount of water needed.

The most common type is the rooftop rainwater harvesting system. It collects the rain from a rooftop and stores it in a cistern or tank for later use. The rooftop system is usually combined with an underground storage tank to store water for periods when there is no rainfall or when there is extra demand for water.

Another type of system is the ground-level rainwater harvesting system which collects water from areas like sidewalks, driveways, patios, etc. It then filters and stores it in an underground storage tank or cistern before using it for irrigation purposes or other purposes such as flushing toilets.

Finally, there are also some other types of systems like storm-drainage catchment systems which collect storm runoff from gutters and channels it into tanks.
