The managing director of a major housebuilder has admitted it may take workers another eight months to fix faulty sewers at its troubled Lathro Meadows development in Kinross.

James MacKay of Persimmon Homes made the admission in a letter sent to a local politician providing an update on the company’s ongoing efforts to address frequent complaints from residents about blockages.

Mr MacKay told Ochil and South Perthshire MP John Nicolson the company takes “full responsibility” for the problems plaguing the system and has now appointed a new contractor to “remedy” the situation.

He went on to admit workers will need to rip up newly laid roads to replace parts of the system but said they would strive to inconvenience as few people as possible.

The letter comes six months after Mr Nicolson told the PA Mr MacKay had assured him all outstanding problems with the system would be fixed by February this year.

Mr MacKay said in his letter to Mr Nicolson, a copy of which the PA obtained through a third party: “Following our series of surveys and investigations, we have agreed a programme of works to remedy the problem.

“This plan calls for a series of non-intrusive remedials to the existing storm water sewer and intrusive excavations to replace the foul water sewer. This will unfortunately require us to dig up parts of the road on the development.

“Our contractors are now onsite undertaking some pre-start enabling works and we anticipate that all works will be complete by the end of February 2022.

“Once the sewer work is done we will also complete the final road surfacing.

“Both plans have been devised in consultation with Scottish Water and Perth and Kinross Council’s roads department.”

Mr MacKay went on to admit Persimmon will continue to rely on tankers to remove waste from the scheme’s sewers when blockages occur while the system is being fixed.

It is understood waste management company Enviro-Clean has been emptying the system at regular intervals on behalf of Persimmon since at least October 2019.

Mr MacKay added: “We sincerely regret the disruption that this has brought and continues to bring to the adjacent development at the point of outfall but this is unfortunately a necessary measure.”

John Nicolson MP remarked this week: “At last Persimmon Homes has listened to common sense and local residents.

“No-one should have to live with overflowing drains.

“It’s been obvious for some time that there was a major failure in the infrastructure installed by Persimmon Homes and I am glad that they have finally agreed to put things right.”
