Public Works

General Information

The Public Works Department oversees the following areas: solid waste division, Northern Plains Regional Landfill, airport, street and central garage, municipal buildings and grounds, sidewalks and driveway installation, sanitary and storm sewers.

The Public Works Department is located in City Hall, 418 2nd Avenue West and it is open from 8:00am to 5:00pm Monday through Friday.

Street Division/Central Garage

In most cities, the Street Division is not responsible for maintaining tree sites or airports. Our department maintains both sites. At the Spencer Municipal Airport, our employees do the mowing, provide hangar and building maintenance, and provide upkeep of the 450 runway lights, and runways so they will be clean and ready for incoming and outgoing flights.

One of this divisions important duties is plowing snow, accumulating approximately 3,500 hours each year. It takes roughly 8 hours to plow the entire City after a normal snowfall, using 10 operational vehicles in the process.

The Street Division is under the direction of the Public Works Department. A staff of 11 full-time employees and including 2 mechanics and 2 part-time seasonal employees help to keep our city on the go.

Combine Sewer Overflow Public Notification

What is a Combined Sewer Overflow or CSO?
In the City of Spencer, like many other cities in Iowa, some sewer pipes carry both wastewater (used water and sewage that goes down the drain in homes and businesses) and storm water (rain or melted snow that washes off streets and parking lots) to the City's Wastewater Treatment Plant. When the wastewater and storm water flow together in the same pipe it is know as a Combined Sewer System. Much of the older parts of Spencer have a combined sewer system. There are four Combined Sewer Overflows (CSO's) locations in Spencer, three empty into the north side of the Little Sioux River and the fourth into a drainageway north of Pederson Park that discharges into Muddy Creek 2.5 miles east of Spencer. A sign placed at the CSO location identifies these structures.

Why is an identification sign needed?
The City of Spencer Wastewater Treatment Plant operates under a National Pollutant Discharge Elimination System (NPDES) Permit issued by the Iowa Department of Natural Resources. As part of our permit we are required to have a public notification program to inform the public what a CSO is.

Do these CSO's discharge into the river often?
No. The CSO's are designed to only discharge into the river during heavy rain events. The City has also developed a plan to eliminate these CSO events totally, by performing sewer seperation projects through 2028..

What other things are being done to reduce CSO events?
Over the past several years the City of Spencer has completed numerous large storm sewer projects that have separated these combined systems in different areas of the city. All new construction and developments are required to have separate wastewater and storm sewer systems as part of their design. The City continues to separate as much of these combined systems as money becomes available. Each time one of these storm sewer projects is completed it reduces the load on the combined sewer system and thus reduces the number of CSO events.

Recently, a new CSO system was constructed to capture the CSO discharges adn pump those to a 8 million gallon equalization pond. In 2013 this system catured 95% of the CSO discharges.
