Introduction to Rainwater Harvesting
Rainwater harvesting involves collecting rainwater from roof gutters, filtering debris, and storing it for non-potable uses such as irrigation, toilet flushing, and laundry. It is applicable to domestic, commercial, and educational buildings.

Domestic Applications
Harvested rainwater can be used for toilet flushing, garden watering, vehicle washing, and laundry. Systems like the Envireau offer integrated solutions for both new and existing properties.

Planning and Economic Considerations
Rainwater harvesting is often required for planning permissions in flood-prone areas or where mains water supply is limited. It can lead to significant savings on water bills, with potential annual savings of £256 for a typical household.

Environmental Impact and Climate Change
With climate change affecting rainfall patterns, rainwater harvesting helps manage water resources by reducing surface runoff and providing a sustainable water supply.

Future-Proofing Homes
The Code for Sustainable Homes promotes rainwater harvesting to reduce water consumption to as low as 80 liters per person per day, enhancing sustainability ratings.

System Options
The Envireau system offers Gravity and Direct options, featuring components like storage tanks, filters, pumps, and control panels. The Gravity system uses a header tank, while the Direct system pumps water directly to appliances.

RainTrap System
The RainTrap system is designed for garden watering, with a filter, underground storage tank, and pump. It is easy to install and suitable for retrofitting without internal plumbing work.

Conclusion
Rainwater harvesting systems provide an economical and sustainable solution for water conservation, supporting environmental goals and reducing reliance on mains water.
