St Thomas More College: New commercial cooking areas — this area required new hdpe lines to service waste requirements from sinks into a new grease trap. All existing required services were located with new connections made into existing services for sewer, water and stormwater. All new gas service was installed with emergency stop system. LPG 1st and 2nd stage regulators were installed in system to minimise pipe service runs. All wastes above ground are installed in copper or hdpe where required on this project.
