Kings Row HOA Backflow Prevention and Cross Connection Control Program protects our water supply from pollutants and contaminants that could, under certain circumstances, be drawn into our water supply from individual properties. All irrigation line services are required to have an approved backflow prevention device installed.
The Colorado Department of Public Health and Environment (CDPHE) regulates drinking water quality and standards. The Colorado Primary Drinking Water Regulations (Regulation 11) outlines the requirements for cross connection control and backflow prevention.
In addition to installing a device, the device must be tested upon installation and annually thereafter by a certified backflow prevention tester.
Backflow is the unwanted flow of water or other liquids, mixtures, gasses or substances into the drinking water supply. There are two main ways backflow can occur:
- Backsiphonage occurs when there is a negative pressure in the water distribution system, which draws the water from a private water system into the main water system. This can occur at any time, such as during a water main break or during a large firefighting effort.
- Backpressure occurs when the pressure in a private water system exceeds the pressure in the main water distribution lines that can cause normal flow to reverse.
- Cross connections are actual or potential connections between the main water supply and any other system that could accidentally introduce a contaminant back into the main water supply.
- According to the Environmental Protection Agency, cross connections can be a serious public health hazard if they do not have adequate backflow prevention assemblies installed. There are numerous, well documented cases in which cross connections have been responsible for contamination of drinking water that, when consumed, caused the spread of sickness or disease.
Every residence in Kings Row HOA that has an irrigation system that is permanently connected to potable water must have an approved backflow prevention/cross connection device installed between the curb stop valve and the sprinkler system. If there is a double check back flow preventer installed on the service line, there must also be a reduce pressure double check before the sprinkler system. Anti-Siphon/Vacuum breakers MUST be installed on all hose bibs connected to potable water.
Preferred devices for Kings Row HOA: Febco 765 and Febco 825Y Reduced Pressure Zone
