Newry WwTW

Newry WwTW provides 101,000 PE wastewater treatment for the town of Newry and surrounding areas. Northern Ireland Water (NIW) identified a need for capital maintenance works to be carried out on the existing SBR blower systems, the primary settlement tanks and sludge tanks, the draining and cleaning of the four no. CASS basins and replacement of the aeration grids within the CASS basins.

Enisca Ltd in consortium with civil construction company Graham Construction was engaged by NIW on the LOT1 Non-Infrastructure Framework for the scoping, design, provision, installation, testing and commissioning of all mechanical, electrical, control, automation, monitoring and telemetry / SCADA equipment.

The scope of works at this site was delivered under a two-stage approach to facilitate NIW’s expenditure plan with Enisca providing the capital maintenance and also scoping and investigative works for future planned works.
