Black & Veatch to Upgrade Loughguile Wastewater Treatment

Black & Veatch and its joint venture partner Dawson WAM are making progress at a number of rural sites in Northern Ireland for Water Service's Northern Region Integrated Wastewater Treatment Framework.

Enabling Water Service to reduce the number of small works by redirecting flows to suitably upgraded Wastewater Treatment Works, Loughguile is an example of the type of small-to-medium wastewater projects being undertaken by Black & Veatch, which includes the entire civil, mechanical, electrical and process design, as well as off-site pumping stations, hydraulics and sewerage infrastructure.

The upgraded systems at Loughguile will employ membrane bioreactor (MBR) technology providing substantially better final effluent quality than conventional secondary treatment.

“Black & Veatch prides itself on our ability to draw upon the best resources to support our clients’ needs,” said Niall Rogers, the Black & Veatch project manager for the Loughguile project. “The Loughguile project is an excellent example of our ability to bring together some of the best contractors within Northern Ireland to complete this challenging work.”

A WwTW serving 30 dwellings at nearby Ballyknock is being decommissioned and replaced by a new pumping station that will direct flows through a new 1,700m pipeline to Loughguile, which serves a 2006 PE of 869 and 2030 enhanced PE of 1,353.

Rogers said what makes the project challenging is the requirement to minimize the visual impact of the new works, so the MBR structures have been built substantially below ground. In addition, construction must remain within the boundaries of the existing site while the current WwTW stay online and within compliance throughout the building period.

“Our success to date is a direct result of good communication among the many project teams and contractors,” Rogers said. “In addition, open dialogue helps support the local communities at every level. Working with local businesses and contractors means that residents understand and can discuss the project with team members as opposed to having a faceless workforce on the other side of the fence.”
