Black & Veatch raise standards and control costs for Thames Water at Esher STW
The Target Alliance joint venture of Black & Veatch and Costain has helped Thames Water achieve a tough Freshwater Fisheries Directive undertaking that imposed new Ammonia consent standards at Esher Sewage Treatment Works.
Significantly, Black & Veatch and Costain have successfully delivered a first class solution to its clients needs at a total project cost of less than £5M - compared to an original estimate of £7M.
Bringing major environmental enhancements to this area in Surrey, one of the main innovations that resulted in a large cost saving on design and construction was the introduction of a combined pumping station and two-stage anoxic zone within a single glass coated steel tank.
Black & Veatch was also highly innovative in its methods of construction, including the use of hydro-demolition, instead of using traditional hand-held heavy breakers, which can lead to hand arm vibration syndrome (The construction team worked over 50,000 hours with zero reportable accidents).
The complex commissioning phase of the project required detailed planning, which was undertaken by the entire project team at commissioning workshops. These brought about the conversion of Esher STW from two separate process streams (filter and crude ditch) into a single settled sewage ditch stream, with clearly defined routes and processes for the sludge flows. At the workshops, the interdependency of each item to be commissioned was analysed to determine the correct commissioning sequence. Contingency plans were also discussed in the event of any process area failing.
Ann Weston, Thames Water Project Manager at Esher, commented:
"I really admire the beauty of the finished project. Black & Veatch and Costain must be congratulated on the completion of a very successful contract".
She added: "We also accomplished the project below Control Cost, which is another bonus. I hope that I can work with them again sometime in the future".
