"DISGUSTED" campaigners are hoping London's mayor can step in and stop part of a £4.1bn super sewer being built near a school.

They have been joined by Lewisham Deptford MP Joan Ruddock in slamming Thames Water's plans for Deptford Church Street, which would see around three years of building work.

The company's controversial project, which would have its access chamber built in Deptford, is designed to deal with millions of tonnes of sewage which overflow into the Thames.

Following a consultation, the company announced this week that it still planned to use Deptford Church Street.

But Oliver Seal, who helped organise an 800-signature petition against the plan, said: "Obviously we're shocked and disgusted at the conclusion. It doesn't look like they've taken into account our comments or concerns."

Noise pollution, safety risks and the effects on neighbouring St Joseph’s Primary School and the Grade I listed St Paul’s Church have all been flagged up as issues, along with the road's northbound carriageway being shut for some of the work and an adverse effect on businesses.

Ms Ruddock said: "Thames Water say that they have listened, but they have obviously not heard us. They are dumping on Deptford and I and the local community will seek to do all we can to get them to change their decision."

She added: "I have immediately written to the Mayor of London Boris Johnson asking him to stand by his election pledge to oppose the choice of Deptford Church Street."

A spokesperson for the mayor, said: "The mayor is disappointed that Thames Water's re-published plans do not take into account the growing concerns expressed by local communities about the severe disruption this project would cause, which is clearly worse than was initially anticipated.

"The mayor has recently written to the Secretary of State proposing the appointment of a suitable expert to reassess the Thames 'super sewer' project, specifically in regard to cost and its impact during construction, to make recommendations on how to proceed."

Thames Water said there would be a further six-week period this summer for the public to review its final plans.

Phil Stride from the company said: "I can personally assure everyone who participated in the process that every step of the way we have carefully taken on board the content of every feedback form, every letter and every petition we have received."

He added: "Unfortunately, there are no easy or disruption-free options for building this much-needed piece of infrastructure, but we remain as determined as ever to reduce the impacts at the proposed sites as much as possible, whilst ensuring we deliver value for money."
