Cardiff Bus Wash, Wales, UK | 2011
Project information
The public transport company Cardiff Bus in the Welsh capital operates a fleet of around 240 vehicles, all of which need to be washed regularly. As this uses a large amount of water, they decided to use harvested rainwater for this purpose.
Natural Power UK and Rainharvesting Systems Ltd developed a special solution using a sectional tank with a separate compartment at one end into which the distribution pumps, UV disinfection system and controls were installed.
In the first six months of operation, the system collected and used 447,000 litres of rainwater, which resulted in significant savings for Cardiff Bus. In 2011, the project was recognised by the Sustainable Water Industry Group (SWIG) as the best example of a retrofitted water saving project.
