Protecting You and Your Drinking Water System from Potential Contamination.

Note: businesses located outside Town of Lyons proper will be prompted to skip the following two sections.

Did you know that your drinking water system is susceptible to contamination through water usage in your own building? This can happen when the drinking water system is connected to uses that make the water no longer potable. This is commonly referred to as a cross connection. Common cross connections found in a building are:
Fire Sprinkler Lines, Irrigation Sprinkler Lines, Boilers, Automatic Soap Injectors, Hoses in Sinks, Hose Bibs, Alternate Water Supplies, Swimming Pools, and Display Fountains.

Under certain conditions the unintended reverse flow of fluids can pass through a cross connection and could potentially contaminate the drinking water distribution system presenting an immediate health risk to you and potentially to your neighbors.

Cross connections within buildings cannot always be avoided but they can be controlled. Local jurisdictions require that private buildings be protected from contamination from cross connections in accordance with the local plumbing code. The Colorado Department of Public Health and Environment requires that public water systems control cross connections at all applicable service connections through various assemblies and methods. Cross connections are typically controlled via the use of air gaps, check valves and backflow prevention assemblies.

Under certain circumstances, a private residence may have a cross connection that is not covered under the local plumbing code. The Colorado Primary Drinking Water Regulation 11 requires that your water provider ensure that an adequate backflow prevention assembly is installed at the service connection or at the point where the cross connection is created. The attached questionnaire is intended to provide you with the opportunity to evaluate your building for potential cross connections and ensure that your drinking water system is being protected adequately from potential contamination. It is also intended to allow the water purveyor to identify any cross connections that are not covered under the local plumbing code.

Please note that the Colorado Revised Statutes 25-1-114 (1)(h) do not allow anyone to install, maintain or permit an uncontrolled cross connection that is connected to a drinking water system that supplies water to the public. Your building is connected to a water system that supplies water to the public.
