The U.S. Bureau of Reclamation constructs dams, power plants, and canals, and delivers water to more than 31 million Americans. The Bureau also operates the Leadville Mine Drainage Tunnel (LMDT), which drains off and treats water from the local mining district so it can be safely discharged into the Arkansas River.

At the LMDT, the Opto 22 SNAP PAC System is used to monitor water levels, remove metals, adjust the water’s pH, reduce water turbidity, and otherwise treat the water before releasing it—cleaner even than everyday drinking water. More than 2500 I/O points are monitored, controlled, and alarmed.
