Breakdown of Rates  What you pay & Why

You may be wondering what exactly the BOD5 and TSS charges are.
BOD5 and TSS charges are instrumental in proper treatment of our wastewater.


5-Day Biochemical Oxygen Demand (BOD5)
This is a measurement of the oxygen levels used over the course of 5 days. This reading provides an accurate calculation of how much oxygen is necessary within the wastewater in order for microbes to dispose of the contaminants in the water. Since there is a continual flow of wastewater at the treatment plants, it is important to test regularly as the concentration of contaminants has the potential to fluctuate and thus adjust the oxygen needed.

  • For 5-day Biochemical Oxygen Demand in excess of 1.6 pounds (256 mg/L) for each 100 cubic feet of wastewater, an additional charge shall be made for each such excess pound or fraction thereof as set out above.


Total Suspended Solids (TSS)
This is a count of the solid matter that flows out of the treatment plant and is filter tested in the lab. It can include a range of particulate items, such as plant matter, animal matter and silt. Having this measurement provides us the opportunity to make treatment plant adjustments to ensure that the treated water we are discharging is clean and complies with NPDES permits issues by the Missouri Department of Natural Resources. 

  • For Total Suspended Solids in excess of 1.9 pounds (304 milligrams per liter) for each 100 cubic feet of wastewater, an additional charge shall be made for each such excess pound or fraction thereof as set out above.


The city shall have the right to measure and determine the strength and content of all sewage and wastewater discharged, either directly or indirectly, into the city's sanitary sewerage system in such a manner and by such a method as it may deem practical in light of conditions and attending circumstances of the case, in order to determine the proper charge.


The determination of BOD5 and TSS contained in the wastewater shall be in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," as written by the American Public Health Association, American Water Works Association and the Water Environment Federation.
