A new Energy Recovery Centre has been installed at Severnside, Bristol, South Gloucestershire with the facilities to handle 400,000 tonnes a year of residual municipal waste from the London Boroughs of Brent, Ealing, Harrow, Hillingdon, Hounslow and Richmond-upon-Thames. The new development will export around 34 megawatts.

  • The MEP systems designed and installed on site consisted of several buildings with different functions. These include:
  1. Staff and Visitors Accommodation Block
  2. Tipping Hall for incoming waste handling trucks
  3. Waste holding bunker
  4. Ash handling bunker for handling hot ashes from incinerating process
  5. Boiler Hall with steam boilers
  6. Flue gas treatment area
  7. Turbine hall
  8. Incinerator Bottom Ash Recovery Building
  9. Miscellaneous weigh bridges and security posts
  10. Electrical & controls plant rooms
  • There was a wide variety of Mechanical and Public Health systems designed and installed, such as site wide process water distribution, carbon monoxide control systems, mixed mode ventilation system to boiler hall for temperature control (CFD modelling included), pressurised ventilation systems and general HVAC and public health systems.

  • The project successfully implemented low carbon technologies into the MEP design to reduce the facilities carbon imprint. An absorption chiller and plate heat exchangers were installed to utilise dump steam from the process plant equipment to supply the development with LTHW and CHW.

  • Electrical services systems included traffic management systems, MV/LV distribution throughout site to all buildings, Site wide security and access control systems, general building services to all buildings.
