Your water utility uses a wastewater average because they can’t measure the actual amount of wastewater discharged from your home. Potable water coming into your house is measured with a water meter since the water is pressurized, but wastewater flows out of your home by gravity. It is not easy to measure gravity water flow through a pipe.


Wastewater averaging takes place during the late fall / winter months and determines a cap on the volume of wastewater you will be billed for each month for the next year. You will be billed wastewater volume charges at the lower of your wastewater average or your water volume, whichever is lower.


Wastewater (or waste water) is any water that has been affected by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration". Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities.


This is the best measure of the volume of drinkable water used at the property during the winter months that reasonably estimates the volume of wastewater discharged to the wastewater treatment facilities of Johnson County Wastewater. By using winter water usage, Johnson County Wastewater can accurately estimate the volume of wastewater ...


Wastewater flow measurement systems are generally very accurate. Any continuous flow measurement system that cannot measure the wastewater flow within +10 percent of the actual flow is considered unacceptable for use in measuring wastewater flow. 2.4 Field Investigation Procedures .


Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal or re-use. Tests selected and desired test results vary with the intended use or discharge location. Tests measure physical, chemical, and biological characteristics of the waste water.


Procedures for Measuring Wastewater Flow. This document describes general and specific procedures, methods and considerations to be used and observed when conducting flow measurement during field investigations. You may need a PDF reader to view some of the files on this page.


Department of Environmental Quality. ... Turbidity is a measure of the clarity of the water. As measured, it is a physical property, but a primary cause of turbidity is fine sediment suspended in the water column. ... and other organic wastewater contaminants in surface water. The most common PPCPs found in the Boise River were steroids ...


Phosphorous removal from wastewater. Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters. Its presence causes many water ...


Wastewater averaging is a way for you to save money. Wastewater averaging takes place during the late fall / winter months and determines a cap on the volume of wastewater you will be billed for each month for the next year.
