Understanding the costs and the benefits of rainwater harvesting

Rainwater harvesting is becoming increasingly popular across the UK due to several reasons. By harvesting rainwater, you can reduce your company's water bills, but also help the environment while you are at it.

If you are thinking of starting to harvest rainwater, then you probably have a few questions. Working with our customer support team, we have put together a guide to everything you need to know about rainwater harvesting and what you need to do to get started.

What is rainwater harvesting?

Rainwater harvesting is a process that involves collecting rainwater that falls onto a surface area, such as a rooftop. Rather than letting rainwater go to waste, the rainwater harvesting kit collects the water for it to be stored in a tank. 

Once the rainwater has been collected, it can be used for non-potable purposes. Things such as toilet flushing, water for gardening or water for a washing machine.

What do I need to start harvesting rainwater?

Below is a list of what equipment will need to start:

  • Tank
  • Pump
  • Control unit 
  • Back-up water supply 
  • Overflow and drainage 
  • Backflow prevention
  • Treatment 
  • Safety labels 

How much will it cost?

The cost will vary for a full rainwater harvesting kit and the installation. There are several factors that can change the overall price you will pay.

A rainwater harvesting kit can cost between £2,500 to £7,000 depending on the kit you choose. A commercial building may also have other costs built into the kit. 

How will it help me and others?

Harvesting rainwater can be beneficial to you and to others for many reasons. 

A big draw for many people towards rainwater harvesting is how cost-effective it is. You will need to make a first investment to set yourself up with the full kit that is needed, but the long-term savings make up for this outlay. The financial savings from using rainwater harvesting are a big pull factor to switching to rainwater harvesting.  You will save some pennies on your water bills if you have a rainwater  harvesting system fitted.

Looking at the benefits for wider society and our environment, harvesting rainwater reduces the pressure on our water resources. Despite the assumption that our water resources aren’t under pressure, an extremely high amount of water is taken from the environment for human use. As the population in the UK increases, so does the need for water. The Southeast of England is the region where water issues are most prominent. Experts have said that in this region, there is less water per person than in many Mediterranean countries. 

Rainwater harvesting won’t completely solve this issue, but it is a wonderful way to start. By using a rainwater harvesting system, you are reducing the demand for mains water. Reducing the need for mains  water results in less water being taken from lakes or rivers. This will help sustain our water levels for years to come.
