    Brief

    The Contracting Authority is seeking suppliers to design, supply, deliver, install, test, and commission impermeable tank cover systems for wastewater and water treatment facilities. This procurement covers approximately 23 sites (subject to change) across the AMP8 Net Zero Investment Programme, with an additional regulatory commitment site, targeting a reduction of approximately 20,029 tCO₂e in process emissions. The scope encompasses Activated Sludge Plant (ASP) lanes and Liquor Treatment Plant (LTP) tanks used in wastewater and sludge treatment. Tank covers must be suitable for installation over live operational assets without compromising process performance, maintenance access, or operational requirements. Successful suppliers will be responsible for complete design development, calculations, technical drawings, fabrication, quality assurance, delivery, installation, testing, commissioning, and provision of operation and maintenance documentation with warranties. Suppliers must assess existing tank structures for suitability to support the proposed cover systems, including structural condition, load paths, connection methods, and access requirements. Structural investigations and remediation works are not anticipated unless specifically instructed. Suppliers will collaborate with the Contracting Authority and appointed designers to define interfaces with future extraction and treatment systems, though the design and delivery of extraction equipment and treatment processes are excluded from this contract scope.
