Hi. It's been over 10 months since my last update. In the past year, quite a few things have been discovered in and around (but mostly under) Toronto. I'll briefly share some of the more memorable trips, but will be intentionally vague. Sorry.

If you're hungry for frequent up dates, redirect yourself to my blog

Humble Howard overflow sewer. This old brick pipe was built in 1910 originally used as a collector sewer until the 1970's when the mid-Toronto interceptor was built. From then on, sewage from the upstream reaches was diverted near Bloor street in the city's west end, leaving the rest of the pipe virtually dry, save from a few small storm water connections. However, Humble Howard is the western-most connection to the Western Beaches Storage Tunnel, a massive project aimed to minimize the amount of untreated sewage from entering the lake. There are three large containment tanks that line the shoreline, one being just east of Humble Howard's south diversion chamber. The thaw this past spring saw significant backups that crept up at least a kilometre upstream through this brick conduit. Even with modern preventative measures, it's as hard as it ever was to keep our city and the lake clean.

Alas, Poor York
The former district of York is primarily serviced by one main network of two combined sewers that span east to west. The southern branch, completed in 1930, is standing height, whereas its newer sibling to the north is not. This system was indirectly, but not consciously, discovered years ago by means of a rather insignificant storm drain, which shared an outfall with a large combined sewage overflow storage tank. This tank, which is fed primarily by an winding overflow tunnel-bored conduit linked to the aforementioned sewer, wasn't explored until a couple of years ago. It wasn't until this past spring that the sewer was explored extensively, and finally seen completely this past month.


A few kilometres upstream through the main sewer


The overflow weir.


Twin overflow box pipes that run parallel to the combined sewer (other side of the wall on left).


Overflow sewage makes a 90 degree turn down a tiered drop. It then travels down a tunnel-bored pipe to the storage tanks.

The tank.

Taylortihuacan
A small, short combined sewer in the east-end that overflows into Taylor creek during heavy storms. The name comes from a feature that none of us bothered to photograph. It was of one of the dry drop shafts of the modern overflow portion. The slope of one of the ramps had deteriorated, exposing the horizontal rebar underneath. Combined with all of the debris caught on the steel bars, it resembled an Aztec step pyramid.


The pipe began to shrink upstream of this waterfall.

Chocolate dRain
Perhaps the best storm drain in Mississauga, discovered by a fellow from the neighbourhood. He must have been on YouTube while exploring it for the first time. The drain is positioned very deep underground and plummets into the Credit River ravine via the biggest drop shaft I've ever seen. Water is sent down a vertical chute in a bizarre drop chamber with no way for a human to safely descend. There are also a few other noteworthy features, too.


The drop. Don't trip, it's four storeys to the bottom.


Some waterfall stairs.

That's all for now. There have been a few more new discoveries made recently, too. Check my blog for frequent updates.

The pic of Taylortihuacan is amazing. It looks like an altar dedicated to a water god.

The Taylortihuacan and the pinkish tank photos are wonderful. Thanks for updating, man!

Need to keep testing my blog. Not working as I want it to yet. Thx for the theme. Maybe this will get mine to look better.
