A. 
"Biochemical oxygen demand (BOD)"
means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20 degrees Celsius, expressed in milligrams per liter (mg/l).
B. 
"Chargeable water"
shall be measured by the water consumed on the premises and which subsequently enters the sanitary sewer system, whatever the source of such water; and the same will be metered either by public utility meter or one installed and maintained by the owner of the premises at his own expense and approved by the city. Where the use of water is such that a portion of all the water used does not flow into the sewer system, but is lost by evaporation, irrigation, sprinkling, or is used in a manufactured product, and the person in control provides proof of this fact and installs a meter or other measuring device approved by the city to measure the amount of water so used and so lost, this water may be deducted from the actual water consumption used in calculating the sewer charge. The sewer charges for residential users during the irrigation season shall be computed on the average consumption during the previous nonirrigation season, unless the user elects to install, at his own expense, an approved measuring device to measure water not entering the sewer system.
C. 
"High strength"
means wastewater discharged from commercial accounts with Standard Industrial Classification Codes 5812, 5147, 5093, or wastewater discharged to the sewer system containing a BOD between 700 to 1,050 mg/l or total suspended solids of 700 to 1,050 mg/l.
D. 
"Low strength"
means wastewater discharged to the sewer system containing less than 350 mg/l BOD or less than 350 mg/l total suspended solids.
E. 
"Medium strength"
means wastewater discharged from commercial accounts with Standard Industrial Classification Codes 2051, 5411, or 7833, or wastewater discharged to the sewer system containing a BOD of 350 to 700 mg/l and less than 700 mg/l total suspended solids, or wastewater discharged to the sewer system containing total suspended solids of 350 to 700 mg/l and BOD less than 700 mg/l.
F. 
"Total suspended solids (TSS)"
means total suspended matter that either floats on the surface of, or in suspension in, water, wastewater or other liquids, and that is removable by laboratory filtering as prescribed in "Standard Methods for the Examination of Water and Wastewater" and referred to as nonfilterable residue expressed in milligrams per liter (mg/l).
G. 
"Very high strength"
means wastewater discharged to the sewer system in which the average of the BOD and total suspended solids
BOD mg/l + TSS mg/l
2
exceeds 1,050 mg/l.

The irrigation season shall be defined as the period of May through October.
