Rushmoor STW to increase sludge capability.

Between 2008 and 2026 the Rushmoor STW catchment is expected to grow by nearly 100%. This growth will significantly increase Rushmoor's current production of primary and SAS sludge. By 2016 this will result in the digesters of the Rushmoor Sludge Treatment Centre (STC) being approximately 65% under capacity. To ensure this doesn't happen Severn Trent Water are investing in 2 new sludge digesters.

Following on from the excellent work Franklyn Yates Engineering have completed at Rushmoor STW, we have been contracted to deliver the mechanical pipework systems design and installation on the new sludge digester's on behalf of the principal contractor Mott MacDonald Bentley (MMB).

This project is another chance for Franklyn Yates Engineering to demonstrate its technical ability and capability to deliver the project to the highest quality, on programme and within budget.

This project includes the following installations:

  • Indigenous Primary & Imported Sludge Screens (including Washwater Supply)
  • Sludge transfer progressive cavity pumps
  • PFT feed progressive cavity pumps
  • Submersible mixer units
  • Thickened primary sludge transfer ram pump
  • Blended SAS transfer progressive cavity pumps
  • Pre-digestion Blending Tank Pipework
  • All pipework and free issued components, including valves, mixers and telemetry
