Water Distribution
The Water Distribution Unit is responsible for maintaining and repairing the water main that carries water throughout the Village's water distribution system and for the public portion of the water service line. The public portion of the water service line is the service line from the water main to the buffalo-box or shut-off valve, located within the Village's right-of-way. The Section’s responsibilities also include water main maintenance and repair, leak detection, hydrant testing and inspection, hydrant maintenance, water valve exercising, and maintenance. 

About Water Main Breaks:
 All reports of leaks and water main breaks are investigated as soon as possible. Water main breaks may leave some customers with little to no water pressure. These breaks are given the highest priority for repair. A repair usually takes four to six hours to complete after a water main break has been confirmed. There are times when repairs must be prioritized. Public Works appreciates customers' patience as the work is completed as quickly as possible to restore water service.

Why Water Main Breaks Occur:
Main breaks are most likely to occur during extreme weather conditions. Cold weather is the most common cause for main breaks and both air and water temperatures are contributing factors to water main breaks. Hot and dry weather is the second most frequent time. Ground shifting and increased volume and pressure can stress water mains.

The Village of Arlington Heights appreciates customer calls about water main breaks or leaks. When you call, it is important that you provide a street address, cross street, or intersection to ensure that the correct area is inspected.
