1. Case Study Drainage at Koo Wee Rup Bus Terminal

2. With Koo Wee Rup expanding at the rate it is the bus terminal needed upgrading, the land where it is was first built on was just a dirt paddock, to endure there was no corrosion and a solid foundation, rain water needs to be drained away.

3. Materials needed to be strong enough to take the weight of the gravel placed on top of it. Slots not to let grave pass into pipe. Connect to standard drainage fittings. Pipe to be 300 Stormwater corrugated pipe Rubber ring Joints. Continues on next slide……….

4. Carry specific amount OD water through it. Meet a specific open area. To be slotted to the drawings requirements Meet Collapse pressure strength Easily transported and light weight.

5. The solution was to use 300mm standard blackmax stormwater pipe Manufactured to Australian Standards Slot Pattern machined was 4mm slots by 3 rows The above specifications allowed the collection of water from the surface at the rate required Meet Collapse Pressure

6. To use Australian Pipe Manufactured to AS1477 The slotted pipe was machines on one our automated slotters to the required pattern specifications

7. To use Australian Pipe manufactured in Australia The slotted pipe was machined on one our amnaul slotters to the required pattern specified Due to quantities being low it was decided to machine the slots on the manual machine. By using Blackmax made handling was easier for both parties, as this pipe comes in 6m lengths. Continues on next slide………….

8. It was decided to slot in-between the ribs of the pipe to ensure maximum strength of the pipe. With the pipe being light, we could deliver the pipe ourselves on a ute with pipe racks, keeping the delivery time to a minimum.

9. Case Study Find other suppliers in Australia Use standard slotted drain pipe that would not meet the specifications. Use Imported cheap pipe. Slot pattern by using hand tools. Thus having inconsistent slot width and patterns. If slotting each slot by hand held machine, run the risk of having an accident and getting OHS Involved.

10. After the successful installation of the drainage system and completing the infrastructure, all drain water was removed from the are and the ground could then be surfaced without fear of damage from underlying water. All passengers are now loading on to the buses from solid dry ground having little risk of slipping on wet muddy ground.
