Thames Water are investigating a leak on one of their pipes on Tulse Hill.
They have a number of teams currently working on contingency plans with regards to turning off the main and the repair. They are aiming to have these plans in place within the next 24 hours so that they can then begin the repair job.
Residents should not experience any interruption to their water supply.
In terms of customer disruption they have two-way traffic lights in place on the junction between Tulse Hill and S.Circular Road.
In order to carry out the full repair, they will need to close a road and will be working very closely with Lambeth council in order to ensure that causes as little disruption as possible.
They are keen to reassure residents that they are working hard to ensure the leak in the pipe does not get worse.
