Quintrell Downs residents assured new Kier homes will not overload sewage system

CONCERNED residents in Quintrell Downs have been assured a 117-home development on their doorstep will not overload the area's sewage system.

Flooding engineer Pete Hocking, from South West Water (SWW), spoke to homeowners and community leaders in Garden Way and Trethiggey Crescent at a site meeting on Thursday.

He told them he had received "categorical assurances" that the existing infrastructure will cope with output from the extra homes.

Locals claim manhole covers on their streets regularly burst open, and the problem can only get worse once The Village is built over the road by developers Kier.

Mr Hocking said: "I've been told categorically that the pipe has sufficient capacity to take what it takes now, and what it will take from the new development."

Under original plans, piping from the new homes at The Village was going to be linked to the existing system down South Road, away from residential properties but revised proposals show it will be connected at Garden Way.

Mr Hocking said it had been SWW's preferred option to connect the pipes away from the housing estate – although he did not say this was due to any reduced risk of flooding.

On Thursday he was led on a tour of the Trethiggey Crescent housing estate where residents, including the area's Cornwall councillor, John Fitter, showed him where sewage had burst through manhole covers in the past.

Neighbours say it has been a problem for at least five or six years, and can be exacerbated by surface flooding from storms and heavy rain.

However, a spokeswoman for Kier confirmed that storm drains from The Village would be directed in the opposite direction.

She said: "As the storm drain from our site will be going in the other direction, towards the River Gannel, we would expect the amount of run off currently experienced by residents of Garden Way and Trethiggey Crescent to be reduced."

In a statement addressing residents' concerns, SWW said: "We have used computer modelling to confirm there will be adequate sewerage capacity in the local network to cope with the extra flows."
