Backflow Regs - Building Codes, City Ordinance & State DEQ Regs

CITY OF GILLETTE CROSS CONNECTION CONTROL and BACKFLOW PREVENTION PROGRAM

The Purpose of the City’s Cross Connection Control and Backflow Prevention Program is:

  1. To protect the public potable water supply of the City of Gillette from the possibility of contamination or pollution by isolating the customer’s internal distribution system(s) or the consumer’s private water system(s) from such contaminants or pollutants which could backflow into the public water systems.
  2. To promote the elimination or control of existing cross-connections, actual or potential, between the consumer’s in-plant potable water system(s) and non-potable water system(s), plumbing fixtures and industrial piping system(s).
  3. To provide for the maintenance of a continuing Program of Cross Connection Control which will systematically and effectively prevent the contamination of pollution of the City of Gillette’s potable water systems.

Summary and State Contact Information
The City’s Cross Connection Control and Backflow Prevention Program is a State of Wyoming DEQ requirement that the City was mandated to adopt per Ordinance(PDF, 276KB) in 2004. The US EPA and Wyoming DEQ perform annual audits of our backflow program to ensure we are keeping up with the retro-fit and new installation of backflow devices for all City water customers.  If you have any questions about the State DEQ Regulations, please contact the water/wastewater program at DEQ. https://deq.wyoming.gov/water-quality/water-wastewater/
