The project was to rehabilitate the existing main sewer running beneath St.Catherine Street and Bonnygate in Cupar, Fife. This being the main tourist route to St.Andrews amongst other places, to say it was traffic sensitive would be a gross understatement. Previous emergency works carried out on this sewer, due to collapses in the past had brought the town to a standstill, resulting in a damaged reputation for Scottish Water.
After detailed examination by the FMS man entry survey team, we were able to put forward designs, options and solutions to rehabilitate the 279 Lm of 1450mm high x 850mm wide stone arched sewer including its 43 lateral connections and 14 side entry sewers.
Regardless of which rehabilitation technique could be employed, traffic and public disruption would be inevitable, however, with detailed planning and close liaison with all parties concerned the effect could be minimised. FMS were involved at all stages in the development of the plan, working closely with Scottish Water Solutions, Fife Roads, Fife Police, Community representatives, MP’s etc.
FMS took responsibility for the extensive and detailed Traffic Management plan, which included a major contra flow and diversion system with advanced detailed signage starting a number of miles outside Cupar itself in all directions. FMS brought on board Contraflow Ltd., a Scottish TM Specialist, to install and maintain the system for the duration of the works.
The NO DIG solution offered was to install an Insitu Sprayed Ferrocement Lining, which is a Wrc approved Type 1 structural lining system in accordance with Water Industry Specification No. 04 – 12 – 06. By incorporating precast ferrocement inverts, (FMS Patented element) the sewers existing flow could be flumed rather than overpumped, thus allowing rehabilitation to proceed in live conditions without disruption of service.
