Richard Alan Engineering Thames Water storage tanks


Thames Water

Incorporating Design for Manufacture & Assembly (DfMA) and off-site modular build.

At the Beckton & Crossness sites, two advanced digestion plants were required to provide additional capacity for seasonal sludge treatment of wastewater and ultimately help to deliver greater operational flexibility. Similarly, a new plant at Basingstoke, with centrifuges for sludge de-watering was underway. As part of the treatment process, all sites required complete polymer storage, make-up and dosing systems.

  • Mixing tank with Jetwet® unit
  • Duty / standby transfer pump sets
  • Duty feed tanks and dosing pumps

Benefits delivered by Richard Alan

By delivering storage silos, tanks and pump skids fully assembled and tested, complete with local electrical systems: 

  • Site installation time was significantly reduced
  • The need for project site, safety and risk supervision was reduced 
  • Commissioning was completed prior to delivery

Integrated management of multi-discipline operations – steelworks, mechanics and electrics – allowed for a more collaborative operation. 

“Basingstoke THP required as much plant as possible be built off-site. Richard Alan delivered what we wanted, when we wanted, proving to be an excellent supply chain member.”
