Thames Water Utilities Limited intends to establish a single-lot, multi-supplier framework agreement to deliver inspection, repair, refurbishment and upgrade works to anaerobic digester assets and associated infrastructure across its operational estate. The framework will support the ongoing maintenance, regulatory compliance and enhancement of Thames Water's digester portfolio, which forms a critical part of sludge treatment operations.
