Employees from a housing trust left raw sewage near a public park during the Christmas break.

Brian Chisholm, of Gaddesden Crescent, in Garston, allowed two employees from Watford Community Housing Trust into his back garden on Christmas Eve as they were inspecting sewage systems.

In Mr Chisholm’s garden he has two drains – one for his sewage and the other for his neighbours – after draining his neighbours, the men filled a big blue bucket full of raw sewage including nappies and human faeces.

He said: “The stench was unbearable. I have never smelt anything like it before. I had to go out and when I got back the two men had finished.

“They took the blue bucket full of raw sewage into their van and that was happened.”

The next day on Christmas Day, Mr Chisholm took his dog for a walk and as he was walking into Garston Park, he saw the blue bucket within 15/20 metres into the park.

Mr Chisholm said: “I could not believe two members of the housing trust staff have just dumped this sewage in a public place.

“Many dog walkers use this path and they will let their dogs off before they see the dump sewage. Dogs will bound up to anything. It is unbelievable.

“Leaving this sewage here is not just fly tipping but it is also a criminal offence.”

Because of the Christmas period Mr Chisholm could not contact the housing trust or environment health at Watford Borough Council.

However, despite the staff returning to work on Tuesday after New Year Mr Chisholm has not been contacted and the dumped sewage is still there.

Mr Chisholm said he also concerned they have not done the job properly which will mean he would have to pay for Thames Water to come and fix it.

Ben Johnson, assistant director of property at Watford Community Housing Trust said: “We are extremely concerned about this incident, which we are taking very seriously.

“We are speaking to our contractor as well as conducting a full investigation internally, and while this is ongoing we are unable to comment further on the matter specifically.

“However, we would like to reassure local residents that we expect our staff and any contractors working on behalf of the Trust to uphold the highest standards and behave in a professional manner at all times.”

Watford Community Housing Trust confirmed the bucket of raw sewage has now been removed and an investigation has been launched.
