What is rainwater harvesting?

Rainwater harvesting is where you collect rainwater from a building rooftop via a drainage system and then filtering and storing this for re-use elsewhere within the property for example in toilet systems. Rainwater harvesting are available for both commercial and domestic properties helping them to both become more self-sufficient and sustainable.

Types of rainwater harvesting systems?

Direct System

A direct system collects and send water directly to the point of use within the property which includes a backup connection for the mains water supply fed into the harvesting tank. When required the tank will be topped up temporarily with the mains water supply. The only issue with a direct system is that in an event of a blackout then the appliances connected to the rainwater systems will not work.

Indirect system

Also known as gravity or boosted, an indirect system includes a second smaller tank usually located within the building which acts as a break tank. It accepts the backup connection from the water mains supply, meaning if used at a high level as a header tank, when there is no power available for the pumps, the system will continue to run uninterrupted. When a higher pressure is needed the outlet can be boosted.

Benefits of rainwater harvesting?

Reduce your water bills

You will reduce your water bills as you will be utilising the free water collected from the rain and therefore will have less reliance on the mains water supply.

Water supply security

With continually rising demand and prices from utility companies, rainwater harvesting offers you that independence to control your properties outgoings and also have the peace of mind that you are helping satisfy your own water demand.

Reduce your carbon footprint and help save the environment

Rainwater harvesting provides a renewable solution to water use, meaning it doesn’t produce any harmful pollution, it is a great way to recycle water with any property. This technology is a way that each property can help towards protecting the environment and tackling climate change by utilising natural sustainable resources.
