Recycled water works on their way

Posted: Tuesday 22nd September 2009

Roadworks in Hillingdon just got a whole lot greener following an agreement between Veolia Water Three Valleys and the London Borough of Hillingdon to use recycled materials on all of the water company’s works within the area. Each year Veolia Water Three Valleys replaces an average of 150 kilometres of water pipes and fixes around 32,000 leaks.

Eddie Owen, Network Technical Manager, Veolia Water Three Valleys said: “The company excavates around 80,000 tonnes of material while carrying out its works each year. Previously we sent this material to landfill and brought in new materials to fill the holes and trenches. Now that we have the capacity to recycle the materials that we’ve dug out of the ground in the first place, we have a totally sustainable solution. This also has the added benefit of being substantially cheaper, which means we can offset some of the more costly aspects of running our business such as energy bills which in turn is good for customers.”

After eight years of development with suppliers, highways authorities and other utility companies to find a sustainable solution, Veolia Water Three Valleys is working with Stanmore Quality Surfaces (SQS) who use huge machines to screen, crush and sort the recycled materials into a number of different graded materials for different purposes. Up to 300 tonnes of materials can be recycled each week and re-deposited back into the ground. These products have gone through rigorous testing to ensure that they will stand up to their intensive use.

Philomena Bach, Director of Environment and Consumer Protection, said: “It is great to see our partners working with us to limit the environmental impact of their maintenance work in the borough. “

“It’s taken a considerable amount of time and effort to get to the point where we can now recycle what we dig out of the ground. We’re really pleased that the London Borough of Hillingdon has signed up to this sustainable solution, the more we can recycle the greater the benefit to the environment and the bigger the savings,” added Eddie.
