Water, Sewage, Plumbing Systems Violation
Public Health Reason #05
The availability of sufficient, safe water is a basic requirement for proper sanitation within a food establishment. All water supplied to food establishments, either from public systems or private wells, must meet the requirements of the Colorado Primary Drinking Water Regulations. A sufficient supply of hot water is critical for employee hand washing, washing of equipment and utensils, and general cleaning needed in all food establishments.
In this example there is a direct connection between the building’s potable water system and the contaminated or non-potable water in the container or sink. To prevent the “backflow” of contaminated water back into the building’s water system caused by siphonage, a proper backflow protection device must be installed on the faucet where the hose is attached.
Backflow devices must be correctly installed to assure their proper operation and maintenance. Backflow devices must be installed on all faucets or hose bibs where a hose can be attached, on soap and other chemical dispensing systems that are plumbed to the buildings water systems, on water lines to dish machines and in soft drink carbonator systems.
To prevent the possibility of sewage contacting food or backing up into fixtures such as food preparation sinks, ware washing sinks, ice bins, refrigerators or dish machines, the drainage systems from these fixtures must drain through an “air break” before entering the sewer. This physical gap in the drain line does not allow waste water to back up into fixtures if a sewage back up should occur.
