Understanding the complexities of the treatment process enabled efficient master planning of the site and design of the powerhouse and other superstructures. The site houses the UK’s first eggshaped ‘digesters’ and an architecture of curved metal forms was developed which expressed the scientific function of the facility.

The project was completed ahead of programme, within budget and demonstrated industry best practice in safety, environmental management, design innovation and community relations.

Methane gas which the digesters produce has been used to fuel CHP engines which provide up to 50% of the site’s power requirements. 20,000 trees and shrubs were planted within the new landscape and a comprehensive environmental management plan certified to ISO 14001 includes contaminated land remediation and wildlife conservation.
