Backflow Prevention & Cross-Connection Control
The Town of Mooresville supplies an average of four million gallons of water to its business and residential customers each day. Before the water is pumped to a home or business, it is carefully treated and tested to ensure its quality.
In 1974, Congress established the Safe Drinking Water Act to protect human health from contaminants in drinking water and to prevent contamination of existing groundwater supplies. This act and its amendments require that several precautions be taken to protect our drinking water and its sources. One of these precautions is the installation and maintenance of an approved backflow prevention assembly (link to new Backflow Prevention Assembly page) at the customer’s water service connection whenever a potential hazard is determined to exist in the customer’s system. Without proper protection devices, cross-connections can occur that can contaminate and endanger the public water supply.
To protect our public water supply, backflow prevention assemblies (devices that prevent the backflow of water into the drinkable water) are required for all businesses that present a potential hazard to the Town’s water supply (examples include businesses that have fire protection or irrigation systems, gas stations, restaurants, hospitals, manufacturers, etc.). These assemblies can protect the Town’s drinking water from cross connection with the water on the customer’s premises and protect the business customer from potentially hazardous cross connections in their own system.
