Backflow Testing in Commerce City, CO

Backflow in Commerce City

South Adams County Water and Sanitation District (SACWSD) is the water and sewer provider the city lists, and it calls itself the largest combined water and sanitation district in Colorado, covering more than 65 square miles. Its tap water is a blend of district well water treated at the Klein Water Treatment Facility and Denver Water surface water. A few areas may be served by another district, such as Industrial Park Water and Sanitation, so confirm your provider by address.

SACWSD's backflow program is aimed at commercial users. They must install a backflow prevention device, have it tested when it's installed and every year after by a technician with ASSE or ABPA certification, and email the test report to the district by August 31. The district also points out that both commercial and residential properties have to protect the drinking water supply under the local plumbing code, or the Colorado Plumbing Code.

That matters in a city that grew up around industry. Shops, warehouses and plants off Brighton Boulevard and East 96th Avenue often have multiple connections that need protection, while homes near the Civic Center and in newer subdivisions mostly deal with irrigation devices. SACWSD takes water emergency calls at 303-288-2646.

Test, rebuild or replace

Signs it's time

• August is approaching and the report hasn't been sent
• The device spits water when equipment starts or stops
• A previous tester flagged a failure
• You're opening or changing a business that uses water in its process
• An irrigation device froze over the winter

Seasonal notes

With an August 31 deadline, summer is the busy season for testing. Booking earlier, in late spring, gives time for repairs and a retest if the first test fails. In fall, drain any outdoor devices before freezing nights, and inspect them when irrigation comes back on.
