For years, Milan has complied with an important Regulatory Water Safety Compliance Program known as Cross-Connection Control.
This State Mandated Program focuses on non-residential (commercial) water service connections and onsite visual inspections (coordinated and performed by HydroCorp of Troy, MI) to identify potentially harmful interconnections to the Milan Public Water Supply.
Michigan Department of Environment, Great Lakes and Energy (EGLE) requires Public Water Systems to implement a Cross-Connection Control Program to protect all Water Service Connections.
This web page serves to assist Milan Water Customers with their participation in this important safety program. The city has selected HydroCorp to assist with Coordination, Site Visits, and Data/Compliance Management.

The anti-siphon fill valve device is located in the tank of your toilet. This device has a dual purpose: To fill the toilet and prevent backflow. This device must be placed at the proper height in order to insure that water from your toilet does not backflow into your drinking water. Proper placement is typically done during the installation process but can be easily overlooked. This device must be raised or the overflow pipe must be cut down in order to achieve a 1” air gap separation between the “critical level” of the assembly.
