Due to the recent wet weather events and ground conditions, works around the Upper Ellesmere intake have been postponed until further notice.

The scheme will remain running in the meanwhile.  There may be temporary disruptions as the intake is blocked (due to river conditions), however works are underway to reinstate the flows at the intake.

We apologise for the change in plans, and appreciate your understanding in this matter.
