Melbourne Water and the Pipelines Alliance have started work on a $41 million project to help improve drainage in Frankston and provide increased protection from flooding.

Frankston is situated in a low lying area of Melbourne and is subject to serious flooding during severe wet weather.

The works commenced in September 2009 and involve constructing new underground pipes and improving existing pipelines and infrastructure. The main 1.5 km underground drainage pipe starts at the Monash University Peninsula Campus car park and ends at Kananook Creek.

Sandy, a mts2000 slurry system with earth pressure balance capabilities, has completed the first tunnel drive of 460m (4/2010). Precast DN 2,500 jacking pipes are being laid behind the TBM and will form the final lining for the stormwater drain. The balance of the four shafts has now been completed in advance of the second and third tunnel drives. Shafts are constructed using either secant or contiguous bored piles, specific to the ground conditions.
