£12m upgrade at Derg waterworks completed

A MAJOR upgrade of Derg waterworks costing £12 million has been completed, NI Water has announced.

The work involved the construction of a new £8 million clarification process and a £4 million carbon addition project at Derg Water Treatment Works (WTW).

Mark Mitchell, NI Water’s head of Integrated Capital Delivery said, “We are delighted to announce the completion of this major upgrade at Derg, which will bring many improvements to our customers, including improved water quality and security of the local water supply.

“This key improvement scheme will also protect and future-proof the local water infrastructure for customers, businesses and tourism in the area.”

The existing Derg Water Treatment Works was built in 2002, and replaced the old works a few hundred metres from the current site.

The 18-month construction contract was completed by Castlederg-based Lowry Building and Civil Engineering as part of the wider DLG Water Ltd, with Belfast company RPS providing project management specialist support.

The project will improve the efficiency of the existing works and will increase the throughput of Derg
WTW to over 26 million litres of water per day from the River Derg
and, more recently, the Strule.

The works serves the Strabane and Omagh areas, as well as supplying water into the Fermanagh area.
