Backflow Prevention

What is a Cross Connection? 
A cross connection is defined as any real or potential connection between the public water system or your drinking water and a source that could contaminate or pollute that water.

What is Backflow?
An undesirable reversal of flow of water. Backflow occurs when a loss of water pressure causes water in pipes to flow in the opposite direction, often due to the opening of fire hydrants, abnormally heavy water use, or a water main break.

Educate Yourself
Cross connections can occur ever day but often go unreported. They can cause health problems and can negatively affect the overall quality of your water. Our goal is to make you aware of the possible dangers associated with cross-connections and to help you understand the importance of Logan City's cross-connection program.

Backflow Prevention

Backflow prevention assemblies and devices provide protection against contamination or pollution of your drinking water system. Examples of potential cross connections include landscape irrigation systems and utility sinks.

Recognizing Cross-Connections
All homes and facilities have potential cross-connections. Common cross connections include:

  • Garden hose; left in bucket of soapy water or cleaning chemicals, weed sprayers
  • Landscape irrigation systems (most common); water accumulating by sprinkler heads and loss of water pressure causing that water to be sucked back through your plumbing, carrying fertilizer, pesticides, animal waste, or other bacteria.
  • Swimming pools/hot tubs
  • Private wells
  • Medical equipment
  • Fire protection systems
  • Businesses using chemicals
