Wastewater service

The City of Bartlesville offers wastewater/sewer service to its residents thanks to a partnership with Veolia Water North America Operating Services, which operates the Chickasaw Wastewater Treatment Plant, located on North Hensley Boulevard.

The City encourages responsible disposal of all products through the wastewater/sewer system, and asks that certain products be disposed of using other methods.

What not to flush:
  • Disposable wipes of any kind, even if labeled “flushable” “Wipes don’t break down in the sewer line and have become one of the No. 1 causes of sewer backups,” Lauritsen said.
  • F.O.G. (fats, oils and grease) “This includes cooking oils and grease flushed through the sink or dishwasher and greasy scraps sent through the garbage disposal,” Lauritsen said. “F.O.G. cools and congeals down the line, sticking to pipes.”
  • Feminine sanitary products including tampons, applicators and pads
  • Diapers and nursing pads
  • Dental floss
  • Paper towels and tissues
  • Hair
  • Cotton balls and Q-tips
  • Condoms
Helpful tips
  • Collect fats, oils and grease (F.O.G.) in a container and dispose of it in the garbage. Prior to washing any cookware or dishes with F.O.G. residual, wipe it down with a paper towel and discard the paper towel in the garbage.
  • Common sources of F.O.G. include:
  • Oil from cooked meats and fish
  • Gravies, sauces and soups
  • Cooking oil, butter, shortening, lard and margarine
  • Milk, cream, sour cream and mayonnaise
  • Oily or greasy food scraps.
  • Scrape or discard food scraps in the garbage prior to washing dishes.
  • Dispose of disposable wipes, even ones labeled “flushable,” feminine sanitary products, diapers, dental floss and paper towels in the garbage.
  • Install and maintain a backflow device and/or a pop-up cleanout.

Sewer System Improvement Oversight Committee

The Sewer System Improvement Oversight Committee is a group of volunteers who work to assure that the City has an efficient sanitary sewer system and is in compliance with regulations established by the Federal Environmental Protection Agency (EPA) and the Oklahoma Department of Environmental Quality (ODEQ).


The SSIOC works with the City engineer and staff to identify existing problems, establish priority solutions and recommend phased action plans and bond issues to accomplish results in the most cost-effective manner.

There are seven voting members on the SSIOC including one voting City Council Representative.  The non-voting City staff advisor is the City engineer.

Meetings are held on the second Monday of each month at 4 p.m. in the Council Conference Room on the first floor of City Hall.
