2026-11-03

The scope of this design and build project is for an overarching design and anaerobic digestion (AD) system that broadly includes: • Source separated food waste feed & ancillary system • Reception hall (A300) pit sump management system • Digester raw waste buffer tank(s) • Pump upgrades & ancillary systems • Heat exchanger upgrades & ancillary systems • Pasteurisation tank(s) & ancillary system • Effluent buffer tank(s) & ancillary system (solid-liquid separation of digestate to enable future accreditation to PAS 110) To do this, the supplier will carry out the following activities through their programme of works: • Design of the AD plant inclusive of civil engineering, structural engineering, mechanical and electrical engineering, systems engineering, and temporary works design. • Procurement and supply of AD assets whilst prioritising the Authority's key objectives of safety, reliability, efficiency, ease of maintenance, and simplicity. • Installation of assets inclusive of delivery and positioning, systems integration, control and monitoring installation, and quality and safety verification. • Commissioning activities including but not limited to system checks and functional testing, subsystem integration testing, calibration and controls, operational simulation, and regulatory compliance. • Acceptance testing to ensure the AD Plant operates at capacity, achieves design criteria, and complies with any relevant regulatory and contractual obligations.
