What Is Rainwater Harvesting?
The practice of gathering, treating, and reusing rainwater.
​
Typically collected from rooftops, filtered, and stored in large tanks for later use.
​
Involves filtration, storage tanks, disinfection, and distribution pumps.
Provides a cost-free water source.
Properly designed systems with appropriate treatment methods offer a reliable alternative to mains or private water supplies.
​
Rainwater lacks minerals compared to mains water, requiring mineral supplementation for human consumption.
Sustainable Water Source
Reduces dependency on mains water supply while providing a renewable, environmentally responsible water solution for your facility.
Cost Reduction
Significantly lowers water bills and utility costs by utilising free rainwater for non-potable applications such as irrigation, toilet flushing, and cooling systems.
Regulatory Compliance
Supports environmental regulations and sustainability targets whilst contributing to BREEAM credits and corporate social responsibility goals.
Water Security
Provides backup water supply during restrictions or shortages, ensuring business continuity and operational resilience.

What Is a Typical Process?
Reverse Osmosis
​Specialised filters remove debris, leaves, moss, and other potential contaminants from entering the tank.
Storage tank designed with a specific size to meet demand.
Either chemical disinfection or ultraviolet (UV) treatment ensures the water is free of microbiological contaminants.
Minerals are reintroduced into the water supply if needed.
