The project included approximately 2200 meters of 1200mm sanitary sewer and 210 meters of 600mm watermain installed my microtunneling. The 1200mm sanitary sewer was installed using a single passed method with RCJP directly installed. The 600mm watermain was installed inside a 1500mm diameter jacked microtunnel CPP with an inside steel liner. The sanitary sewer works required the construction of 6 shafts, each 7.14m diameter, varying in depth from 24m to 30m.

The project also consisted of 3.6km of 3m diameter Tunnel in shale (800m using rockbolts & mesh and 2,8km using ribs & lagging), with a 1500mm carrier CPP being installed within the excavation. The watermain works required the construction of 6 shafts with a diameter of 14.1m with varying depths ranging from 22m to 29m.

The sanitary sewer was excavated using a 1.5m diameter slurry MTBM and the watermain tunnel was excavated utilizing a 3m main beam TBM and a 3m diameter single shielded mixed faced TBM.

All shafts were constructed by ribs/wire mesh/shotcrete in the overburden and rockbolts and plywood in the shale, with the exception of 3 shafts constructed using secant piles for overburden support.
