Clients love our traffic light system

Conversations with our drainage contractors and their clients have revealed a very clear message. They love our traffic light colour coding system! The system makes it incredibly easy to understand drainage survey reports and where remedial recommendations need to be made.

The system is built on the WRc (Water Research Centre) serviceability grading system, where a Grade C is a drain that requires repair and Grade A means the drain is good. We have added to this using a simple colour coding system.
