Northern Ireland Water’s Maghaberry Wastewater Treatment Works (WwTW) serves the Maghaberry area including residential, trade and a local prison, but due to capacity issues and aging assets at the existing works, investment was required to support growth in the local community and meet regulatory discharge standards to protect the adjacent Glen River.
McAdam developed a concept design for a replacement 6000PE works comprising of a combined sewer overflow, inlet works, storm holding tanks, primary treatment tanks, secondary biological treatment tanks, final settlement humus tanks, sludge holding tanks and associated pumping stations. The new structures were elevated relative to existing to reduce risk of flooding while maintaining gravity in flows to the Works.
The works was delivered under an NEC3 Option A design and build contract with McAdam undertaking Project Management and Principal Designer role, and was successfully completed in 2019.
