Certain types of businesses and industries are required to have a backflow prevention assembly or backflow elimination method to protect the drinking water distribution system from contamination should a backflow incident occur.
These businesses and industries include:
- Breweries
- Car washes
- Chemical and pharmaceutical plants
- Dental and medical offices
- Food and beverage processing facilities (including restaurants)
- Hospitals, mortuaries and veterinary establishments
- Laboratories
- Laundromats
- Metal plating industries
- Nursing homes
- Schools and colleges
- Service stations and auto repair services
In addition, your company’s facility is required to have a backflow prevention assembly or backflow elimination method if it:
- Uses an irrigation system
- Is four or more stories high
- Houses multiple commercial offices
- Is a warehouse or high-density multi-use residential complex served by a master meter
The type of protection required will depend on the degree of hazard that exists or may exist. The degree of hazard (either high, moderate or low) is based on the following:
- The harmful makeup of contaminant
- The potential health hazard
- Potential for backpressure or backsiphonage
- Potential effects on the drinking water distribution system
If you are not sure whether your business requires a device, or if you are unsure if your current device provides adequate protection for your facility, contact WCSA at 276-628-7151 to arrange a free survey or assessment and recommendation.
