The median Commerce City home was built in 2005, but about 12% of the housing dates to the 1950s, in the historic areas around Rose Hill, Adams City, and Derby.
Old core, new neighborhoods
In the older neighborhoods, it's sewer laterals, galvanized pipe, and aging water heaters. In Reunion, Buffalo Run, and other newer areas, it's builder-grade fixtures and first water heater replacements. Commerce City's water district, South Adams County Water & Sanitation, softens drinking water to about 7 grains per gallon. Irrigation water runs on a separate, unsoftened system.
Commercial and industrial properties
South Adams County Water & Sanitation requires commercial water users to test backflow assemblies at installation and every year, with reports due by Aug. 31. We test, file the report with the district, and quote any repair before doing it. Backflow testing in Commerce City →
