The Engineering Division is responsible for overseeing the City’s Combined Sewer Overflow (CSO) Program, which is also governed by state and federal regulations. Some of the City’s underground sewer and stormwater pipes are connected together and can discharge directly to nearby surface waters during heavy rain events. These discharges, collectively referred to as CSOs, must be minimized to protect surface water quality.
The City's Combined Sewer Overflow Facilities Plan, updated in May of 2022, provides a rational basis for effectively reducing CSO discharges in compliance with our 9/5/17 Maine Pollutant Discharge Elimination System (MEPDES) permit and Waste Discharge License.
In addition to overseeing a wide variety of construction projects in the City, the Engineering Division also provides a variety of engineering support services to other municipal departments.
