Project details

The existing Clay Lake WTW was in need of refurbishment to remove odour and taste problems from the public water supply. Competitively tendered, NIW chose a unique solution to solve this problem retaining existing key peripheral plant and new process equipment. The works were installed in a new portal steel clad building located on the part of redundant slow sand filters to minimize excavation for the new works.

Working with civil engineering partner Lagan Construction Group, Laganwater 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 GAC tanks into the new works one at a time. This meant NIW could keep producing water without interruption.

The new works included Dissolved Air Floatation Tanks, Rapid Gravity Sand Filters, Granulated Activated Carbon adsorbers and Manganese Removal Filters. Laganwater commissioned the works (in two stages) operating the works between Stage 1 and 2 in partnership with NIW. Full NIW Operator training was provided by Laganwater.

Our successful delivery of the Clay Lake WTW was recognised by three prestigious industry awards; CEF Awards for the Utilities Infrastructure Category and the overall award on the evening and RICS Awards for the Infrastructure Category.
