A fairly grubby crag upstream (and therefore in no danger from) the sewer works on Stockdill Drive near Macgregor. Access is difficult to describe and very much cross country - essentially park right near the plant and walk to google maps coord -35.258971,148.981025
Septic Sector & Cave Routes have straightforward access following the directions below, but sewer wall has many routes starting with a hairy traverse over the water on untrustworthy bolts. Ideally you would abseil in to get to the cliff, but there are a few issues with this - firstly there are no trustworthy trees up top, nor anywhere to place gear for an abseil, and secondly between half to the entire cliff has water at the bottom depending on recent rain!
As you approach there is a very steep ramp to the left that can be used to access the cliff. Be careful.
As of last view (early 2010) the bolts on Sewer Wall were rusting and may not be trustworthy. This is not a well-attended crag - climb here at your own risk, it's an adventure even finding it. Septic Sector & Cave Routes were bolted 2014
Located about 10 minutes drive from Belconnen and either a 15-20min walk or 5min 4WD, climbs vary in height from 8-55m, although the original (and longer, harder) climbs have not yet been revolted and are probably NOT SAFE.
The original wall is in shade most of the day but through Summer Septic Sector & the Cave Routes are in full sun in the afternoon. The water is a great way to cool off; it's upstream from the water treatment plant so you're safe & it's usually a nice temperature throughout the warmer months.
It gets dark very quickly once the sun touches the Brindabellas in the West, and the start of the track back can be difficult to find, so pack a torch, as well as a camera not just for the climbs but for awesome scenery and an abundance of turtles, lizards &, yes, piranha carp.
Get yourself to Stockdill Dr, Holt, & follow it a way until you can glimpse the water treatment plant in the gaps between trees.
Drive past Shepherd's Lookout to a locked gate on your left & a 'no camping' sign after the last corner. A driveway for Actew Water is opposite.
Jump the gate & follow the dirt track to a dam. Cross the dirt bridge (dam on left, tree in hole on right) & follow a faint trail over the rolling paddock. You'll see a large line of brambles with a several-metre gap between them, walk just to the left of these & continue in a straight line over a rise to the top corner of the paddock closest the river.
Jump the gate in the corner & turn left, following the trail closest to the fence line crossing the first gully & then passing just to the right of 2 large trees on top of the following crest. Continue straight as the path crosses another gully, on your way out of the gully follow one of several tracks contouring the next rise to the right. Follow these until you pass into and out of the young pine forest.
Turn right, going downhill along the edge of the pine trees. Pass through a clearing following a faint trail (straight) & follow faint trails to a very large gum on the edge of the cliff. This is the top of Cave Routes.
Follow the trail downhill & left, staying close to the cliff until, just after stepping over a fallen tree, there's a clearing to your right & a lone tree near the edge of a 15m cliff. About 4m past the tree is the top of Hung Like A Sewer Rat, & you can scramble around Septic Sector from here.
Follow the river downstream to the obvious big wall for Sewer Wall.
