Kier has secured four Thames Water contracts worth nearly £65M to upgrade wastewater infrastructure at sewage treatment works in Hertfordshire, Buckinghamshire and Surrey. The programme will focus on modernising key process units, including inlet works, settlement tanks and sludge treatment streams, to improve treatment performance and regulatory compliance under the current Asset Management Plan period. Civil and M&E scopes are expected to involve complex brownfield tie-ins, maintaining full treatment capacity during construction and integrating upgraded process control systems into existing works.
