Some customers have No Water or Low Pressure in the E17 Area. We are
still trying to determine the source of the issue.
Should you notice a burst main in the area, please contact us on 0800
316 9800. This can also be reported on our website or via our Social
Media team www.twitter.com/thameswater.
As soon as we locate the issue we will aim to restore your supply as
quickly as possible.
