Councillors on Norfolk County Council's planning committee unanimously agreed to an expansion of Anglian Water sludge treatment centre in Clenchwarton.

It announced last summer plans for the £4.5 million expansion at its facility in Clockcase Lane to enable it to run at full capacity.

A report to councillors said the works are currently operating at 60pc.

Nearby residents have opposed the plans since they were submitted, raising concerns about poor infrastructure surrounding the works.

Afterwards, Alexandra Kemp, Norfolk County Councillor said: 'It was very disappointing that the committee missed an opportunity to get good infrastructure secured for Norfolk. A facility like this needs a proper road at the very least.'
