RAINWATER is being harvested to clean drains and road gullies on the Isle of Wight, in an a Island Roads green scheme.
The company, which nearly a year ago took over responsibility for the Island’s highways, has installed huge storage tanks for 60,000 litres of rainwater at its Stag Lane depot near Newport.
Island Roads says it is planning to clean all the Island’s 22,000 gullies and drainage systems over the next two years and the increased use of water led to the recycling scheme.
The company said it was previous practice only to empty gullies and push a limited volume of water through to clean them, but it used the 'jet-vac’ process — blasting water at very high pressure to remove build-ups of silt.
It says it has up to five tankers and ten staff involved in making gullies and drainage systems less likely to contribute to highway flooding.
The highways PFI company re-uses water recovered through the flushing process and water used for washing vehicles too.
Island Roads’ environmental services manager Dave Wallis said: "An important part of the highways PFI contract is ensuring we manage our carbon and water footprints very carefully.
"It means that while the Island’s gully and drainage network gets a very high level of cleaning it is done in a way that uses resources extremely carefully."
