Charles Brand and Lagan MEICA successfully delivered the £2.7 million contract for Northern Ireland Water (NIW) at Clay Lake Water Treatment Works (WTW) in County Armagh. Clay Lake WTW involved the refurbishment of the existing water treatment works which addressed customer taste and odour issues.

Competitively tendered, NIW chose a unique solution to solve this problem; retaining existing key peripheral plant and providing new process equipment. The works were installed in a new portal frame, steel clad building located on the site of redundant slow sand filter bed to minimize excavation for the new works.

Lagan MEICA designed, installed and commissioned the new process plant. Existing treatment chemical dosing systems were integrated into a new automatic control system for the WTW. The Construction sequence allowed for the installation of two existing refurbished GAC tanks into the new works one at a time. This meant Lagan MEICA could keep producing water without interruption to the network, maintain quality and increase the capacity of the plant.

 All works were constructed, installed and commissioned without interruption to the consumer.

The new works included Dissolved Air Floatation Tanks, Rapid Gravity Sand Filters, Granulated Activated Carbon absorbers and Manganese Removal Filters. The works were commissioned in two stages, remotely operating the works between Stage 1 and 2 in partnership with NIW and supplying compliant water to the network at all times. Full NIW Operator training was provided by Lagan MEICA for NIW.

Our successful delivery of the Clay Lake WTW was recognised by two prestigious industry awards; CEF Awards for the Utilities Infrastructure Category and the CEF Overall Winner Award on the evening and RICS Awards for the Infrastructure Category.
