CSO SPRING CLEANING 2019 Phase 1

Mayor Anthony Copeland and the East Chicago Sanitary District are announcing the first Phase of the CSO - main sewer line annual cleaning effective March 25th. The Sanitary District team will start with the areas listed below and detailed on the attached map in the following order:

• Marktown Area
• New Edition Area
• North Side Area
• West Calumet Area

During the sewer cleaning process residents may encounter possible sewer backups and odor in their homes due to the high pressure cleaning system the city’s Freightliner Vactor truck puts out. Therefore as a precautionary measure, the city recommends you cover all floor drains, sinks, showers, and toilets located throughout your home to avoid these issues.

Every effort will be made to inform the residents as the city approaches the specific targeted areas listed above with street closures through fliers, nixel, and the city website.

This first Phase of the CSO - main sewer line annual cleaning is necessary and will be done in a safe and efficient manner. We apologize for any inconvenience this may cause. If you have any questions, please call Joe Wright at 219-391-8466. We thank you for your patience and cooperation during this process.
The East Chicago Sanitary District, Wastewater Division Collects, conveys, and treats wastewater. The Sanitary District service area is approximately ten square miles. The collection system/sewer piping is approximately 72 miles long and varying in size from 8 to 96 inches in diameter.

Once the wastewater enters into the collection system, it is then pumped to the Wastewater Treatment Plant at 5201 Indianapolis Boulevard. We have 11 Pumping Stations throughout the City of East Chicago. They consist of Sanitary, Stormwater and combination of both. The facility was rehabilitated in 1988 as a Three Stage Wastewater Treatment Plant.
First State Treatment

This is also known as preliminary treatment. There are two bar screens that have 5/8 inch openings and six feet width. The bar screens remove materials that flow into the sewer system with the wastewater, i.e., cans, paper, rocks, bottles, plastic, etc. After screening, the wastewater goes through a four foot measuring device called a Parshall Flume. The flow is measure to adjust the treatment means in the plant. From here, the abrasion to the pipes and valves in the treatment system.
Secondary Stage Treatment

This is a form of biological treatment in the oxidation ditch. There are two oxidation ditches with an approximate capacity of 8.42 million gallons with an average detention time of 13.5 hours at an average flow rate of 15 million gallons per day. Bacteria are the biological means used to remove organic material, ammonia and phosphorus. Four aerators with 150 hp motor turn turbine like impellers to add oxygen and velocity to the micro organisms in the water.

Five clarifiers perform a liquid/solid separation. The clarifiers also use physical means. They are 12 feet in depth and 100 feet in diameter. The clarifiers have a total capacity of 3.52 million gallons. Overflow from the clarifiers goes to the Third Stage of Treatment.
Third Stage Treatment

Rapid Sand Filtration filters the clarifier effluent through sand media and porous plastic plate. There are 6 filters that are 62 feet in length and 16 feet wide and approximately 11 inches of media. This media is very similar to sand on the beach. After the third stage treatment, wastewater is disinfected through ultraviolet disinfection. There are 1,312 light bulbs submersed in water and having a wavelength of 253.7 nanometers that penetrates cell walls of bacteria that can cause diseases. This type of treatment disrupts the DNA change thus killing the microorganisms and disinfecting without harming the environment through the use of harsh chemicals.

Also, bio-solids or sludge dewatering is conducted with 2 belt presses, approximately 2 meters wide and operated 6 hours daily.

The Wastewater Treatment Plant has approximately 35 employees that maintain, operate, clean sewers, repair the sewer system, maintain grounds and perform all administrative duties.
