The City of Dixon has taken an active role in maintaining the quality of the local environment for more than 70 years. since 1930, the city has provided wastewater collection and treatment for its citizens. As the population has grown and state and federal regulations have evolved, the city has continued to update and improve its collection and treatment system.

The improvements to the wastewater treatment facility in 2000 allowed the City of Dixon to continue the stewardship of the local environment. “Clean Water for the New Millennium” will promote growth in the city for the next 20 years. The following is a timeline of improvements to the Dixon Wastewater system.

Timeline of Improvements

1930Original collection and treatment facility is built.
1962New wastewater treatment plant is constructed. Plant processes include:

  • Laboratory
  • 4 communutors
  • 3 primary clarifiers
  • 12 aeration basins
  • 2 final clarifiers
  • 2 anaerobic digesters
1972Chlorine contact tank and building added for disinfection of final effluent as required by the Illinois Environmental Protection Agency (IPEA).
1985New final clarifier, return sludge pumps and stand-by generator added.
1992Swissville sanitary and storm sewer improvements.
1993Southside trunk sewer construction.
1994River Street sanitary sewer replacement from Sheridan Ave. to Harrison Avd. 2,729 lineal feet of 30″ diameter sanitary sewer. This project reduced infiltration into the collection system by 500,000 gallons/day.
2000dix-treatment-aerial-domes.jpgNew wastewater treatment facility constructed to comply with the state and federal regulations. Northside interceptor installed from Reynoldswood Lift Station on the north bank of the Rock River to the new wastewater treatment facility which eliminated the Reynoldswood pumping station. (1,000 lineal feet of 30″ diameter sewer.)
Screw Pump Rehabilitation and Southside Flow Meter Project:

The Wastewater Treatment Facility has two- (2) wastewater screw pumps located at the head works of the Facility. The purpose of the pumps is to lift all of the incoming wastewater into the Facility for treatment. The pumps are rated at 18 million gallons a day each (MGD), they are 75′ long, 9′ in diameter and raise the raw sewage 40′. When the pumps were installed in 2002 they were the longest screw pumps in North America.

The pumps are made from steel and are coated to protect the metal. The pumps run 7/24/365 a year and are in a very harsh environment, which requires them to be recoated every 8 to 10 years.

The scope of the project included; Screw Pump sand blast and painting, influent channel cleaning, slide gate repair, slide gate actuator installation, Southside flow meter installation, lower bearing assembly replacement, deflecting plate replacement, upper bearing and coupling inspection, bypass pumping.
