Maintenance & Repair
The Wastewater Division is responsible for maintenance and repair of over 230 miles of pipe ranging from 8 to 36 inches in diameter, 15 miles of easements, 7,336 manholes, and 23 pump stations.

Maintenance activities include but are not limited to: closed-circuit television (CCTV) inspection, high-pressure hydro-cleaning, easement and pump station maintenance, daily monitoring of the SCADA (Supervisory Control and Data Acquisition) system, and activities related to providing excellent customer service.
Maintenance 2
Most maintenance and repair activities are conducted in City streets. The Wastewater crew utilizes flashers on their trucks, traffic cones, reflective clothing, and radio communication to ensure a safe and productive work environment.

Wastewater Division staff repair pump stations, pipe, and manholes. Pump station repair involves complex electrical circuits, pumps, and equipment. Manhole repairs range from frame and cover replacement to entire channel and bench restoration. Pipeline repairs range from open trench pipe replacement to slip lining damaged sections of pipe.
Mainteance 1
Many of the maintenance and repair activities Wastewater Division staff conduct are in confined spaces with potentially hazardous atmospheres. 

In order to ensure a safe working environment, staff take advantage of the City’s comprehensive confined space program. One of the crucial components is testing these spaces for oxygen, combustible gases, toxic gases and vapors using portable gas monitors.
