MSD Project Clear By the Numbers – MSD geography
As of today, MSD owns and maintains 9,578 miles of collection and trunk sewers and force mains, ranging in size from six inches to 29 feet in diameter. That’s enough to reach from the Gateway Arch (west) all the way to Apollo Bay in southwestern Victoria, Australia
The system currently includes approximately 4,744 miles of wastewater sewers and force mains (that’s from the Gateway Arch, east, to Turin, Italy), approximately 3,028 miles of stormwater sewers and force mains (from the Gateway Arch, south, to the city of New Amsterdam in Guyana), and approximately 1,806 miles of combined sewers that handle both wastewater and stormwater flows (from the Gateway Arch, west, to Nanaimo, British Columbia, Canada – aka the “Bathtub Racing Capital of the World”).
Check out this page for more genuinely interesting facts about the Metropolitan St. Louis Sewer District. (Seriously, there’s a lot of great information there. For example, did you know that some of the sewers maintained by MSD are more than 150 years old? I mean, really! 150 years old! No wonder MSD Project Clear is so important!)
