When I first saw this water pumping station just off the Tennessee River, I assumed it was related to the operations of our public water utility.
There's a water treatment plant less than 3 miles away, so this seemed like a reasonable assumption. But then some oddities started presenting themselves!
Control wiring just kinda hanging out in the open, a weird utility connection to a generator and ATS across the street, romex just hanging down from the control house connecting to a boathouse (no way that's up to code), and also, hold on, a boathouse?? That's not really my utility's style… they usually run access roads, and indeed, there could be an access road pretty easily built to this site.
This map turned out to hold the solution. There's a rail spur connecting a site a few minutes away (Norton Rd) to this area ("PUMP STATION"). Clicking through to property tax data shows that the pump station, the area where the utility lines run, and the area where the rail spur terminates are all owned by the same org, Norton Co. No public ownership here. But it's not totally clear why this is…
A short drive down Cap Adkins Road solves this mystery too. It's an industrial ceramics facility, now known as Saint-Gobain Ceramics. The water from the pump station probably ends up in this water tower.
A review of historical aerial imagery shows this pump station going up sometime in the 1950s, which lines up with Saint-Gobain's public history notes — the facility opened in 1955 as Norton Abrasives (or Norton Materials, hard to say, there are conflicting d/b/a names in reference materials I found). Saint-Gobain bought Norton in 1990.
An article from December 1956 in Chemical and Engineering News (now an ACS publication) is the only third-party reference I can find to the facility opening (thanks to Hunter for helping me track this down), and unfortunately there is not really a lot of info on why they chose to build their own pump station instead of working with the local utility. Huntsville Utilities was probably smaller back then, and their water service area may not have extended this far out; the city only annexed this area in the late 1980s. But maybe it's cheaper to do it this way regardless!
