The City of Moline has 195.45 linear miles of roadway it maintains. This equates to over 700 lane miles. This does not include alleys or routes of other jurisdictions that traverse through Moline like Route 92 or 19th Street south of Avenue of the Cities. There are 107 traffic signal locations in Moline, the majority being signalized intersections along with several traffic controlled crosswalks. This staff and activities related to signals is managed by Engineering. Pavement types are a combination of sealcoat, bituminous and concrete.
The City has 240 miles of water main and 17,652 water services. Of these, 15,813 are residential. There are 5,000 lead service lines in that number. Moline is working aggressively beginning in 2021 to remove lead service lines from the network. Moline is responsible for all components of the service lines from the main to the curb box in the ROW. Some water main and piping still dates back to the 1800’s.
- Sanitary Sewer
The City has 227 miles of sanitary sewer and 16,600 sewer laterals. Like water services, the City has responsibility for sewer laterals from the main to where the ROW meets the customer’s property line. Because of the topography of Moline, the City has many dead ends and uses 15 sanitary sewer pumping stations to convey wastewater to one of the City’s two treatment plants. The City has three National Pollutant Discharge Elimination System permits which is unique for a community the size of Moline.
The City uses a combination of ditches, drainage ways and detention along with curb and gutter incorporated with a piped storm sewer network to manage storm water. There is 175 miles of storm water piping ranging in size from 4” to 84”. The majority of the City is positioned between two rivers, the Rock and the Mississippi and there are 6 public storm stations in the network that assist in getting the stormwater conveyed to their river destinations.
