NI Water is progressing a major £12 million upgrade at its Derg Water Treatment Works (WTW) where construction work is well underway.

The water company said the essential investment would not only improve the water quality within the Derg network but would also provide additional security of the water supply to customers in the Castlederg and Strabane supply area and further afield.
The existing Derg Water Treatment Works was built in 2002, and replaced the old works a few hundred meters from the current site. The upgrade will see the construction of a new clarification process and activated carbon addition, which will enhance water treatment at the Derg WTW site.
The 18-month construction contract is being undertaken by Castlederg-based Lowry Building & Civil Engineering as part of the wider DLG Water Ltd, with RPS providing project management specialist support. Work is expected to be completed by March 2023.
Once complete, the project will also improve herbicide and organics removal at the plant, improving 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, Strule.
The works serves the Strabane and Omagh areas, as well as supplying water into the Fermanagh area.
