These two drains follow what used to be Kardinia Creek. The smaller one, The Connector, was the original drain constructed during the early 1960s.
Half drain was later duplicated in 1980, diverting the western half of the catchment into the new bigger drain.
Entrance: 1.9m
Materials: Concrete
Shapes: Round
The outflow to the drain starts of with this chest high dam of water. Weve used boats to get in before but if its a nice summer day you may aswell just walk in. The dam wall has a slippery slope so be careful when entering on foot.
The section from the outflow to the first set of twin rcp pipes is the diversion to the old drain. It cuts the western branch off of the old Kardinia creek drain
After a pretty long walk of solid nothing the first offshoot is this little but very steep pipe. It was pretty wet and we stopped here and used it as a slide for a bit before continuing onwards.
From the slide to the twin loops there is absolutely nothing, not even sidepipes or gutterboxes.
The drain gets much smaller as we go on through the loops until the last split where it goes from 1.8m to two 1.2m pipes.
These two pipes merge and split a few times before splitting into 3 parallel 900mm pipes, which if youre game enough do lead to the inflow. All up its about 350m of back breaking. Might be a good way to avoid the wet at the entrance.

This is the og drain, the real one.
Entrance: 1.6m
Materials: Concrete
Shapes: Round
This drain keeps it interesting with all the small chambers, double barrel pipes, and variations in height. Most of the chambers have little grilles in them that let some light in, pretty good for photos.
Overall the drain is pretty stoopy but there are a few sections where it jumps up to 1.8m, although most of the drain is smaller.
The final split were these two parallel RCP pipes and these ones didnt get bigger upstream unlike the rest throughout this drain. We decided to turn back because we saw something much more interesting. A vertical sidepipe.
Getting up this one was quite a hassle as there wasnt much to grab onto, but after a whole ordeal we all got up there. The council maps I had gotten showed that this sidepipe connects to the slide sidepide in Geelong drain.
After a little stoop we were bested by this drain. The sidepipe has been filled in. The maps had lied.
