Wastewater, which is commonly referred to as "sewage", is collected from homes and businesses in Mesa through an intricate network of underground pipes. For homeowners, the pipe used to carry wastewater from their property is called a lateral line. The lateral line connects to a sewer main, which is often located in the street. The responsibility to maintain and clean the lateral line belongs to the owner. The City of Mesa is responsible for the mainline.
The collection system transports the wastewater to one of Mesa's three wastewater reclamation plants. These plants treat the water for reuse on golf courses, crop irrigation, greenbelt irrigation, and for recharge. By reusing the water, the City of Mesa conserves fresh water that can be used in our drinking water system.
Mesa's wastewater collection system includes:
- A service area of 170 square miles
- 121,000 service connections
- 1,600 miles of sewer mains
- 39 miles of force mains (pressurized lines)
- 30,000 manholes
- 19 sulfide stations (for odor control)
- 16 lift stations
