In this entry, we&#8217;ll begin to go underground, but first, a bit more history&#8230;<\/p>\n<p>I mentioned the use of hydraulic machinery and how it was powered by water by the aqueduct. Only a small portion of that water (less than 5%) was actually sent through the pipes and into homes and businesses. By the late 1800s, several problems with this system started to make it less than ideal. The first issue was that demand for water was increasing and more horsepower was required to distribute it. The aqueduct at the turn of the century, roughly a quarter the width it is today, was incapable of providing the hydraulic horsepower necessary to power the pumps.<\/p>\n<p>On top of this, the success of system was often at the whims of mother nature. Low water levels in the summer and ice blockages in the winter frequently reduced pumping capacity. As a result, steam power, which was both cost and labour intensive, would then have to be used as a back-up.<\/p>\n<p><!--more-->Another problem was that the water was being brought in directly close the shoreline of the St. Lawrence River, which by this time was starting to become less than pure. City officials maintained that the water posed no health risks. However,  there was a concern that drainage from properties situated upstream of the entrance to the aqueduct had the potential to cause future problems. Given that there was still no filtration process yet in place (and wouldn\u2019t be until the early 1920s), engineers were starting to become somewhat mindful of what could possibly be entering the city&#8217;s water supply.<\/p>\n<p><strong>20th Century Solutions<br \/>\n<\/strong><\/p>\n<p><strong><a href=\"http:\/\/www.undermontreal.com\/wp-content\/uploads\/2009\/05\/conduit_diagrams.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-828 alignnone\" src=\"http:\/\/farm4.static.flickr.com\/3663\/3548948221_2e4ed5012a.jpg?v=0\" alt=\"conduit_diagrams\" width=\"500\" height=\"168\" \/><\/a><br \/>\n<\/strong><\/p>\n<p>To address the shortage of available horsepower, in 1907, after two decades worth of proposals and deliberations, it was decided to widen the aqueduct from 40 to 140 feet. Along with upgrades to pumping equipment, the alteration would provide a total of 2,500 HP during the winter months. A rate of 5,000 HP during the summer was achievable when the aqueduct was free of ice, or \u2018<a href=\"http:\/\/en.wikipedia.org\/wiki\/Frazil_ice\" target=\"_blank\">frazil<\/a>&#8216;.<\/p>\n<p>To help improve quality of water, a 9\u2019 concrete conduit running underneath the aqueduct\u2019s north shore was built between 1907 and 1909. In addition, the intake for this conduit would extend  towards the middle of the St. Lawrence, where the water was less likely to contain sediment. By enclosing the water inside this underground pipe, the risk of further cross-contamination would also be diminished. The conduit would also serve as a continuous water supply while the aqueduct was emptied during its widening.<\/p>\n<p><strong>Rumour Has It.<\/strong><\/p>\n<p>I first learned of the conduit a couple of years ago, not through the city archives or maps, but from a <a href=\"http:\/\/verdunourhometown.yuku.com\/forums\/124\" target=\"_blank\">message board<\/a> dedicated to <a href=\"http:\/\/en.wikipedia.org\/wiki\/Verdun,_Quebec\" target=\"_blank\">Verdun<\/a> . In a bit of oral history, an older member recollected a time during his youth when he and his friends would open a manhole cover near the north side of the Crawford Street Bridge and climb down into a \u20189 foot pipe.\u2019 This was enough to pique my interest. I decided to go have a look for myself.<\/p>\n<p>When I arrived, the only manhole I could find in the area was now in the middle of Blvd De La Verendrye- a rather busy thoroughfare. If it was the same one he entered, then it must have been before the 1960s which was when they built the road . I walked further along the street hoping to find other options, but every single one was situated in the road. Feeling a bit dejected, I filed it under \u2018things to look for if ever bored\u2019 and left it at that.<\/p>\n<p>A few months passed before I came across another reference to the conduit, this time in a city planning document from the 1930s. I learned that the pipe was connected to the waterworks system. A few weeks later, when Controleman came back from the City Planning department with a handful of sewer maps, one of which made clear where the conduit ran, that it was no longer in use, and more importantly, where the best point of entry was located.<\/p>\n<p><a href=\"http:\/\/www.undermontreal.com\/wp-content\/uploads\/2009\/05\/aqueduc_conduit_citymap.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-823\" title=\"City planning map detail showing aqueduc and the old water conduit (in red).\" src=\"http:\/\/farm4.static.flickr.com\/3330\/3548947847_1eb5f1467d.jpg?v=0\" alt=\"aqueduc_conduit_citymap\" width=\"500\" height=\"344\" \/><\/a><\/p>\n<div id=\"mycaption\" style=\"padding: 5px; background: #e9e9e9 none repeat scroll 0% 0%; width: 491px; margin-bottom: 7px; text-align: center;\">City planning map detail showing aqueduc and the old water conduit (in red).<\/div>\n<p>In what I consider to be a continuation of underground exploration traditions, our entry point ended up being but a few feet away from the manhole that the older gentleman from Verdun once used. A three foot high drainage pipe within Parc Angrignon, just large enough the crawl through, provides a 21st century means of access.<\/p>\n<p><strong>Inside the Conduit.<\/strong><\/p>\n<p><a href=\"http:\/\/www.undermontreal.com\/wp-content\/uploads\/2009\/05\/aqueduc01.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-822\" title=\"Manhole chamber (and groundwater infiltration) underneath Blvd. Verendrye \" src=\"http:\/\/farm3.static.flickr.com\/2481\/3549792384_6dc67ebb72.jpg?v=0\" alt=\"aqueduc01\" width=\"500\" height=\"334\" \/><\/a><\/p>\n<div id=\"mycaption\" style=\"padding: 5px; background: #e9e9e9 none repeat scroll 0% 0%; width: 491px; margin-bottom: 7px; text-align: center;\">Manhole chamber (and groundwater infiltration) underneath Blvd. Verendrye.<\/div>\n<p>The conduit itself resembles many of Montreal\u2019s older concrete sewers, but with pronounced horizontal lines from the wooden forms that were used during construction. For a century old tunnel, it\u2019s in excellent. The water is, at times, thigh-deep, but it is slow moving and not that much of an issue assuming you have the stamina to wade through it for long periods of time. Sewage can be detected, but for the most part the water is cleaner than what is usually encountered underground in Montreal. I wouldn\u2019t want to drink it, but I wouldn\u2019t mind falling in it either.<\/p>\n<p>As a testament to its cleanliness, small fish can often be spotted over the course of its length. During one trip, I even came across about a half dozen <a href=\"http:\/\/en.wikipedia.org\/wiki\/Proteidae\" target=\"_blank\">mud-puppies<\/a> that somehow got swept into the system and have done their best to make this dark tunnel their home.<\/p>\n<p><a href=\"http:\/\/farm4.static.flickr.com\/3588\/3548993417_a514ab3dc5.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-821\" title=\"One of many Mud-puppies spotted inside the conduit.

This particular one was close a foot in length.<\/div>\n<p><strong>The Montreal Water Famine of 1913<\/strong><\/p>\n<p>By the winter of 1913, work had begun to widen the canal an additional 25 feet. This further widening was commenced to help generate electrical power for the city\u2019s lighting systems. Rather than have to expropriate additional land on the south side of the canal, the City decided to make the enlargement on the north shore instead, close to where the conduit ran. It\u2019s here where all sorts of problems began.<\/p>\n<p>In the midst of this second enlargement, a two-foot long portion of the conduit was damaged. Workers did their best to try and repair the break, but a few days later, sixty feet worth of the conduit collapsed. The damage left close to 300,000 people in Montreal without a proper water supply. Adding insult to injury, the event occurred on Christmas Day  \u2014 never a good time for catastrophe to strike.<\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/www.undermontreal.com\/wp-content\/uploads\/2009\/05\/waterfamine_nyt1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-825\" title=\"New York Times headline from Dec 28th, 1913.\" src=\"http:\/\/farm4.static.flickr.com\/3658\/3548947889_9002ac80bd.jpg?v=0\" alt=\"waterfamine_nyt1\" width=\"373\" height=\"480\" \/><\/a><\/p>\n<div id=\"mycaption\" style=\"padding: 5px; background: #e9e9e9 none repeat scroll 0% 0%; width: 491px; margin-bottom: 7px; text-align: center;\">New York Times headline from Dec 28th, 1913.<\/div>\n<p>City workers scrambled to repair the break while the people of Montreal had to receive water through water carts or from properties fortunate enough to have access to Cartesian wells. In one instance, Ogilvy\u2019s department store, with a 1,200 foot deep artesian well in its basement, was able to provide water for people in the area. Meanwhile, large factories such as the Angus Shops had to be temporarily closed, while streets were patrolled day and night to react quickly to the first sign of fire.<\/p>\n<p><a href=\"http:\/\/bibnum2.banq.qc.ca\/bna\/massic\/detail\/a-22-a.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-819\" title=\"Buckets of water being handed out from casks during the shortage.\" src=\"http:\/\/farm4.static.flickr.com\/3549\/3548947379_762a4e1624.jpg?v=0\" alt=\"waterfamine_archives\" width=\"500\" height=\"407\" \/><\/a><\/p>\n<div id=\"mycaption\" style=\"padding: 5px; background: #e9e9e9 none repeat scroll 0% 0%; width: 491px; margin-bottom: 7px; text-align: center;\">Buckets of water being handed out from casks during the shortage.<\/div>\n<p>The  conduit was eventually repaired four days after its collapse using sections of boiler plate riveted together to form a steel pipe.

An investigative report submitted to the city\u2019s Board of Commissioners blamed the collapse on both the materials used during construction of the conduit as well as the excavation that had been taking place at the time.<\/p>\n<p>More importantly, the report made several recommendations that would help prevent another such calamity from occurring. Based on the report, an emergency supply pipe running from the Lachine Canal to the pumping engines was soon added as a temporary solution. Ensuring a more reliable back-up supply system wouldn&#8217;t come until later.<\/p>\n<p><strong>Yesterday and Today.<\/strong><\/p>\n<p>It\u2019s not clear at this point when the city stopped using the conduit  for its drinking water supply. It likely became obsolete by the time the filtration plant was put into operation during the 1920s. Impure water running the length of the open aqueduct was less of an issue after that. Repositioning of the system&#8217;s  intake pipes probably also ensured a cleaner supply as well. Also unclear is when (and why) the City officially abandoned its plans to use the aqueduct for purposes of power generation.<\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/www.undermontreal.com\/wp-content\/uploads\/2009\/05\/desbaillets_outlet.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-829 aligncenter\" title=\"Fresh water flowing out from underneath a syphon that presumably connects to the Des Baillets water treatment plant.

The aforementioned relatively clean water and levels of sand (fare probably attributable to the plant&#8217;s filtering system.  A walled off section prevents water from the River from entering the conduit directly. Before this, a section of the conduit has been replaced with a junction chamber with one pipe leading towards the discharge tunnel of the plant.<\/p>\n<p><a href=\"http:\/\/farm4.static.flickr.com\/3356\/3549756532_903849f90f_o.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-827 alignnone\" title=\"Junction chamber situated near the Des Baillets water treatment plant.
