Rainwater harvesting is the process of collecting and storing rainwater as it falls then redistributing it for use in a residential or commercial setting. Rainwater can be collected in a variety of different containers and manually or automatically transported to a building.
Rainwater is a freely available resource that doesn’t require any excess energy to produce and, in many parts of the country, is plentiful all year round.
But relatively few people make use of this bountiful resource within their homes or workplaces.
Harvesting rainwater can:
- reduce your mains water usage,
- reduce energy usage,
- and potentially save you money (especially if you are currently using a water meter).
One of the significant advantages of rainwater harvesting is the relatively low barrier to entry. Anyone of any ability can set up a basic rainwater harvesting and storage system and start using rainwater around their property. It can be as simple as collecting rainwater in buckets.
However, to really take advantage of the benefits of using rainwater, you will want a larger storage capacity than a bucket and a system to pump it around your property.
Rainwater can be used in any area of the home that you would typically use water but is most commonly used for flushing the toilets and sometimes replaces the use of mains water in a washing machine.
One advantage of using rainwater to supply your washing machine is that rainwater is “soft” water. This means you could potentially remove the use of conditioner in your washing cycle.
Most rainwater harvesting systems collect the water that falls on the roof of a building. The storage system is connected to the building’s gutters and downpipes and then left to fill up when it rains.
When water is required within a building, the rainwater is simply pumped from the storage container and used as necessary.
If you are looking for an energy-efficient use of a plentiful and renewable natural resource, then rainwater harvesting could be perfect for you.
