Work is continuing to move forward on multi-million pound upgrades at the Derg Water Treatment Works (WTW).
Approximately £12 million is being invested in the project, which will improve the water quality within the Derg network and 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.
NI Water awarded an 18-month construction contract to Castlederg-based Lowry Building & Civil Engineering as part of the wider DLG Water Ltd, with RPS providing project management specialist support.
When the project reaches completion by March 2023, it 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.
