Water Efficiency and Management

Ferrovial Agroman is working to become more efficient with water usage, to reduce water wastage through re-use and recycling where possible, and to promote the use of sustainable non-potable (undrinkable) water supplies on our Heathrow site.

The objective of this commitment is to reduce the volume of water consumed on our sites through challenging project targets and efficient design.

This has been demonstrated in the following activities:

• The project involves the breaking out of materials which results in the generation of dust. We are only using non-potable water for damping down on-site, therefore reducing the pressure on potable water sources.
• Non-potable water consumption is monitored using water meters at appropriate locations, including construction sites and welfare offices. Usage is recorded monthly on the Smartwaste platform and forms part of the monthly environmental report.
• A high performance vehicle wheel-wash system with water recycling has been installed. This is an automatically activated drive-through spray-wash system designed to prevent spreading site dirt to both public and inner airport roads. It is powered by inverter-driven pumps, which saves 50% energy and consists of a closed loop system effectively recycling the water it uses.
• The project has also installed a modular on-site Water Treatment Plant that enables dewatering without causing harm to those involved, meeting high quality standards and without adversely affecting the environment. The plant also avoids the truck movements associated with water treatment and waste activities off site.
