Rainwater Harvesting System for Aylesbury prison

Aylesbury Prison, in Buckinghamshire, will cut its mains water usage in its new block by up to 50%, thanks to its new Aquaco Rainwater Harvesting System.

The Rainwater Harvesting System will include 2 X 6,750 litre GRP collection tanks, water filtration and UV disinfection units.

The Rainwater Harvesting System is controlled by an Aquaco Master Control Unit which includes dual, duty and assist pumps and 200 litre break tanks which supply mains water in the event of insufficient rainfall.

The Rainwater Harvesting System also includes a temperature alarm to warn when conditions are ideal for bacterial growth within the main collection tanks.

Aylesbury holds the longest sentenced young adult males in the English prison system.

There are 443 young prisoners in single and double cells in eight residential wings.

Rainwater Harvesting System for primary school

The Westborough Primary School, near Southend-on-Sea, has ordered a complete rainwater harvesting system from market leader Aquaco.
