Water Utility Master Plan


The City of Hartford Water Utility delivers safe, high-quality drinking water to your tap every day.  To continue to protect the public health and keep the water system safe from contaminants and pollutants, we are required by the Wisconsin Department of Natural Resources, the Department of Safety and Professional Services and the City of Hartford Municipal Code to maintain a Cross Connection Control Program.



Cross Connection Control  Overview


The City of Hartford Water Utility is working with Hydro Designs Inc. of Brookfield, Wisconsin to manage our Cross Connection Control Program.  Hydro Designs Inc. is an environmental services firm that specializes in backflow prevention and cross connection control.  They currently manage program services for over 80 municipalities and water utilities in Michigan and Wisconsin. 

Representatives from Hydro Designs Inc. will perform the initial inspections of all commercial, industrial and public authority buildings throughout the city to detect actual and potential cross connections and make recommendations for the installation of backflow prevention devices or assemblies where necessary.  This will help ensure that contaminated or polluted water cannot backflow into clean drinking water.


Cross Connection Control  Program


What Is a Cross-Connection Control Program?

This is a combined cooperative effort between plumbing and health officials, municipalities, water utilities, and property owners to establish and administer guidelines for controlling cross-connections and ensuring enforcement so that the public drinking water supply is protected both in the city water distribution system and within buildings to the point of use.

Our program consists of the following components:

Annual Testing

All backflow prevention assemblies will be tested once a year by certified testers, at the property owner’s expense.


Cross-Connection Survey

All industrial, commercial, and public authority facilities’ plumbing systems will be inspected to determine if cross-connections exist and appropriate corrective actions will be outlined if applicable.


Installation of Protective Devices

Where known unprotected cross-connections are identified, property owners will be required to install backflow prevention devices or assemblies.


Public Education Program

We will inform our water customers with newsletters and brochures.  Visit the following web site for more information and resources:


Cross Connection Control Surveys


What is a Cross-Connection Survey?

The cross-connection survey is the first step in our program. Wisconsin Department of Natural Resources Regulations (NR 810.15) recommends that all industrial, commercial, and public authority facilities be surveyed for cross-connections regularly (every two to six years depending on the degree of hazard within the facility).

What’s Inspected?

A survey is a walk-through of the water-system piping in a building or property, starting at the water meter and ending at the last free-flowing tap. Survey time varies depending upon the facility being surveyed. Large, complex facilities will be required to show that they have an internal program to protect the potable water system. At the end of the survey, HDI will produce a report describing any violations or discrepancies found, as well as a time frame for compliance.

Existing Buildings

Surveys of existing facilities will be scheduled based on the degree of hazard that they present to the water system. The first round of surveys will include city-owned buildings, public school facilities, hospitals/medical facilities, car washes, industrial/manufacturing facilities, and mortuaries. Inspection notices will be mailed to water customers approximately two weeks before the scheduled inspection date. A building representative should be available during the inspection to answer questions and provide access to areas within the facility.


Cross Connections and Contaminations


What is a Cross Connection?

A cross-connection is a direct or potential connection between any part of the public water supply system and a source of contamination or pollution. The most common form of cross-connection is a garden hose, which is easily connected to the public water supply system and can be used to apply a variety of potentially dangerous substances, including chemicals and fertilizer. Other common cross-connections include dishwashers, toilets, pressure washers, boilers, pools, and lawn sprinkler systems.


How Does Contamination Occur?

Water normally flows in one direction, from the public water system through the customer's cold or hot water plumbing to a sink connection or other plumbing fixture.

Under certain conditions water can flow in the reverse direction. This is known as backflow. Backflow occurs when a back siphonage or backpressure condition is created in a water line.


·     Back siphonage may occur due to a loss of pressure in the water distribution system during a high withdrawal of water for fire protection, a water main or plumbing system break, or a shutdown of water main or plumbing system for repair. A reduction of pressure below atmospheric pressure creates a vacuum in the piping. If a hose bibb was open and the hose was submerged in a wading pool during these conditions, the non-potable water in the pool would be siphoned into the house’s plumbing and back into the potable water supply.


·     Backpressure may be created when a source of pressure, such as a pump, creates a pressure greater than that supplied form the distribution system.  If a pump supplied from a non-potable source, such as a landscape pond, were accidentally connected to the plumbing system, the non-potable water could be pumped into the potable water supply.
