Rainwater Harvesting System for a Self-Build on the Isle of Wight

Why Rainwater Harvesting Was Chosen

A homeowner on the Isle of Wight wanted to install a domestic rainwater harvesting system as part of their sustainable self-build project. Their goal was not only to reduce mains water usage, but also to meet planning requirements and help mitigate local surface water flooding.

After visiting our stand at the National Self-Build and Renovation Centre (NSBRC) in Swindon, the client contacted our team for advice on specifying the right rainwater harvesting system for their home.

Specifying the Right Rainwater Harvesting System

Using our online rainwater tank size calculator, we assessed the property’s roof area and estimated water usage. Based on this information, we recommended a 3000L rainwater harvesting tank with:

• An integral pump

• A filter

• A direct feed control unit

This setup provides a reliable and efficient way to collect, store and reuse rainwater within the home.

Installation and Flood Mitigation

One of the first tasks for the homeowner was to determine the best location for the underground rainwater tank. At the same time, they planned the installation of additional soakaway crates.

These soakaway crates help manage excess rainwater and were included to further reduce the risk of surface water flooding around the property. As a result, the system contributes to both water conservation and improved drainage.

Monitoring Rainwater Levels

Inside the house, the client installed a Rain Acculevel sensor to monitor water levels within the tank. This sensor provides accurate data on stored rainwater levels, allowing the homeowner to manage their rainwater harvesting system more effectively.

Results After Installation

Since the system was installed, the homeowner has seen significant benefits. The rainwater harvesting system supplies water efficiently while helping reduce reliance on mains water.

In addition, the system supports the property’s wider sustainability goals and helps reduce the amount of rainwater entering local drainage systems.

Client Feedback

When asked about their experience with the system, the client said:

“In the year since the tank was installed, the system has not needed to top up from mains water. This proves the online tank size calculator got it just right. Our water bills have been significantly reduced, and we have the added benefit that rainwater is not contributing to local flooding.”

• Reducing local flooding.
• Accurate tank sizing.
• Future proofing the home.
