Cross Connection Control Department

Department Manager:

Kevin Rosemeyer, 303-674-2121

The Cross Connection Control Department ensures the safety of EMD's water distribution system by administering the Cross Connection / Backflow Prevention program in accordance with the Colorado Department of Health &, Environment (CDPHE) Regulation 11.39. Commercial, industrial, multi-family and some single-family residential properties are required to have backflow prevention assemblies installed, tested, and maintained annually. Backflow prevention assemblies ensure that under certain hydraulic conditions water being used on a customers' premise does not "backflow," or return, into the main public water supply. This is especially important if the customer is using water in such a way that it may become contaminated, i.e. with irrigation, fire suppression, mixing with chemicals, etc.

Program Information:

For Customers

When is my backflow assembly due to be tested?

All backflow assemblies are to be tested annually. If the backflow assembly has not already been tested in the calendar year, a notice will be sent via mail or email approximately 60 days prior to the due date.

Please note: all irrigation backflow assemblies are to be tested no later than 7 days after being turned on.

Who do I contact to test the backflow assembly?

Evergreen Metro District only administrates the Cross Connection Control program- it is the customer's responsibility to have their assemblies tested. Customers may use any backflow testing company. Please click the link below for a list of some contractors that frequent the Evergreen area.
