Magherafelt WwTW serves a mainly domestic population equivalent of 12,000 and in 2007 Northern Ireland Water identified the works as requiring an upgrade to meet the Urban WasteWater Treatment Regulations (NI) 2007 and revised discharge standards set by the Northern Ireland Environment Agency (NIEA).
The design reused existing assets where practicable and included a new storm overflow screen, storm transfer PS, storm tank, inlet works screens, conversion of 2 existing storm tanks to primary tanks, refurbishment of 4 existing biological filters, 2 new intermediate settlement tanks, 2 new tertiary biological filters, 3 new final settlement tanks, an interstage PS, 2 new concrete sludge holding tanks, duty/ standby sludge thickeners, standby generator, odour control and refurbishment of the existing administration building.
McAdam were appointed as NEC Project Managers for the construction phase and were also involved in the development of the scope and outline design, through to tender preparation, assessment, and contract award.
The Moyola River runs from high in the Sperrin Mountains all the way to Lough Neagh. It is one of Northern Irelands most important angling rivers with many miles of spawning beds for salmon and dollaghan. The Magherafelt WwTW project has provided improved treatment to wastewater in the Magherafelt area and helps protect the Moyola River for future generations to enjoy.
