The Sewer Maintenance division of the Department of Utilities consists of approximately 20 employees. These people are responsible for maintaining over 200 miles of sanitary sewer lines, 25 lift stations, and 7 combined sewer overflow control structures. The equipment used by Sewer Maintenance personnel includes high velocity sewer cleaning machines, bucket machines, sewer rodders, backhoes and dump trucks.

In 1995 the Sewer Maintenance Division used high velocity sewer cleaning machines to clean nearly 70 miles of sewer. The recent purchase of two new types of nozzles, one for removing tree roots and grease, and one for cleaning stones and heavy debris from larger diameter sewers greatly improved the divisions ability to provide this service.

Crews used special video camera equipment to view over 65,000 feet of sewer lines of various size. This included all lines in areas where street reconstruction was planned. By viewing sewers in areas where street resurfacing was planned, Sewer Maintenance personnel were able to identify problem areas and repair all main sewer lines before the streets were paved.

Miniature camera equipment was also used to inspect laterals, which run between customers buildings and the city's sewer. These inspections enable us to show customers the condition of their laterals as well as where and how they are tapped into sewer mains.

Some of the services provided by Sewer Maintenance in 1995 include:

• Ohio Utility Protection Service calls - 4,177
• Mini-camera inspections - 234
• Tap inspections - 120
• Raising or lowering manhole castings in newly paved streets - 216
