MWRD: Building the Sanitary and Ship Canal pioneered new technologies

I've read that much of the technology developed to build this canal such as steam-powered shovels was then used to dig the Panama Canal.

Historical photo of the week: Construction of the Chicago Sanitary and Ship Canal at an unknown location in the mid-1890s, showing one of the cantilever incline machines that were used to move broken rock from the excavation areas to the spoil piles
Jeff Bransky It says section 10 on the photo. I noticed that that large conveyor structure is sitting on rails so it can be moved as work progresses. Interesting to see horses at work in the background. I imagine the machine was driven by a steam engine.
Eugene Klichowski Section 10 was between Summit and Willow Springs
I thought the above was a conveyor belt where this end would be lowered into the canal so men could dump debris on it. But the following indicates it is for removing big rocks.

Here is how they got the sidewalls so straight.

Historical Photo of the Week: Workers pause for a photo with a channeling machine during construction of the Chicago Sanitary and Ship Canal (CSSC) near Romeoville on September 25, 1894. Channeling machines were used to make smooth, vertical “wall” cuts on each side of the canal and then the rock between the walls was drilled, blasted and removed. 
MWRD posted the following photos as part of a long write up concerning their 129 year history. They built the main canal in just a couple of years after it was formed, so the districts has branched out into many other projects such as treating the sewage in the 1920s and allowing rain to sink into the ground rather than runoff to the sewers (grass play grounds for schools, green alleys, rain barrels, etc.) in the 21st Century.

Modern day: Kayakers on the main branch of the Chicago River, phosphorus recovered from the water treatment process, Stage 1 of McCook Reservoir, and a green alley in Berwyn.

Three laborers posing next to a compressed air rock drill during the construction of the Chicago Sanitary and Ship canal. The nearly completed sluice gates for the Lockport Controlling Works can be seen in the background. The estimated date is sometime in November 1896. Drilling into rock requires the use of a fluid, or drilling mud, which can be seen splattered all over the workers. Explosives were placed into the holes and detonated, and the rock debris could then be removed from the worksite.

[They are referring to using bricks to create a permeable surface. But notice all of the green recycle bins to keep plastic, etc. out of the landfills. And the brown bag on the left is probably for yard waste so that it can be composed instead of going to the landfill.]
