Design, Supply, Installation, Commissioning and Acceptance Testing of Anaerobic Digestion (AD) Plant

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.
