NI Water is pleased to announce a new £2.6m programme of work to replace Derrycrin Wastewater Treatment Works (WwTW) with modern new infrastructure. Construction work at Derrycrin (outside Coagh) will commence towards the end of November and will continue until early 2024.

In advance of work commencing, Lowry Building and Civil Engineering (LBCE) will set up their work compound and install a temporary treatment plant in lands adjacent to the existing treatment works, located off the Drumenny Road.

Site mobilisation/compound set-up works will commence around the beginning of November 2022 with the temporary plant due to be taken to site around the end of November. Once this has been successfully installed, LBCE will begin demolishing the old works and preparing the site for the new treatment units.

Sean Milligan, NI Water Senior Project Manager said:

“We are pleased to announce this extensive £2.6 million programme of improvements to replace Derrycrin Wastewater Treatment Works (WwTW) with modern new infrastructure.

“The investment will include the installation of state-of-the-art treatment tanks, along with advanced electrical and mechanical systems to provide a robust wastewater treatment solution.

“The new infrastructure planned for Derrycrin will support local development, deliver environmental improvements and ensure NI Water meets EU standards for many years to come.

“NI Water and our appointed contractor, Deane Lowry Jacopa (DLJ) would like to thank the public for their patience while we complete this essential improvement work.”

This £2.6 million investment is an excellent example of what can be done when the necessary funding is in place.


NI Water’s capital funding for year 1 of our business plan was secured and the business looks forward to the necessary funding being put in place across the full six-year period to 2027.
