Protect Your Drinking Water (cross connections)

Your water can become contaminated if connections to your plumbing system are not properly protected!  To protect your water it is important to understand what a cross-connection is and how contamination can occur.

What is a cross-connection?
A cross-connection is an actual or potential connection between the safe drinking water (potable) supply and a source of contamination or pollution.  State plumbing codes require approved backflow prevention methods to be installed at every point of potable water connection and use.  Backflow preventers are required to avoid contamination.  Cross-connections must be properly protected or eliminated.

How does contamination occur?
Certain hydraulic conditions left unprotected within your plumbing system may allow hazardous substances to contaminate your own drinking water or even the public water supply.  Water normally flows in one direction.  However, under certain conditions, water can actually flow backwards; this is known as backflow.  There are two situations that can cause water to flow backward: back siphonage and backpressure.

Back Siphonage
May occur due to a loss of pressure in the municipal water system during a fire fighting emergency, a water main break, or system repair.  This creates a siphon in your plumbing system which can draw water out of a sink or bucket and back in to your water or the public water system.

Backpressure
May be created when a source of pressure (such as a boiler) creates a pressure greater than the pressure supplied from the public water system.  This may cause contaminated water to be pushed in to your plumbing system through an unprotected cross-connection.

If your not sure if the connections to your plumbing system are properly protected, please contact the Village office for assistance, 846-6751.
