Have spoken to Thames Water who said that this particular phase of the project has now finished. They will still be working 24 hours a day but hope that the overnight noise will not be so bad in the future.If that is not the case I will contact Southwark Council but it's a tricky one. The work has got to be done and as it is it's due to go on until 2010. If they don't work at night it could take twice as long and I'm sure none of the local people want that. Once the summer comes and people are sleeping with their windows open it could become very difficult.
