Congress passed the far-reaching Clean Water Act, and it was signed into law by then-President Richard Nixon in October.
Metro beneficially recycled biosolids in 1973 by trucking vacuum-filtered sludge cake (about 16% solids) to the old Lowry Bombing Range, spreading the solid material onto the surface to dry and then disking the dried sludge cake into the soil with farm implements. The applied areas were seeded with wheat after adequate dormant time to minimize seed inhibition.
In December, the South Plant went online when flows were directed there for the first time, roughly doubling Metro’s treatment capacity.
Eight new 244,000-cubic-foot anaerobic digesters were completed in 1977 to digest Metro’s sludge.

The Denver Northside Treatment Plant was shut down.
The District reduced costs by switching to applying sludge cake on agricultural land.
The board changed the name of the organization from Metropolitan Denver Sewage Disposal District No. 1 to Metro Wastewater Reclamation District.
The District completed improvements to the Nitrification/Denitrification System and optimized its performance. This $47.2 million system involved extensive modifications to the District’s treatment facilities.

Metro initiated its Comprehensive Planning Program.
For the first time in its 35-year history, Metro’s employees achieved a million man-hours worked without a lost-time accident.
Metro adopted the Service Area Utility Plan to manage the Transmission System. Flows decreased and farming operations took a hit during a historic drought that hit Colorado and the West.
Metro began a major update to South Platte River Water Quality Model to assess impact of in-plant treatment and in-stream improvements.
