Each nonresidential user's wastewater treatment cost contributions as determined in §§ 51.05 and 51.06 shall be added together to determine each user's annual wastewater service charge. Residential users may be considered to be 1 class of user and an equitable service charge may be determined for each such user based upon an estimate of the total wastewater contribution of this class of user. The Governing Body may classify industrial, commercial and other nonresidential establishments as a residential user, provided that the wastes from these establishments are equivalent to the wastes from the average residential user with respect to volume, suspended solids, and 5-day, 20° Centigrade biochemical oxygen demand. Each user's wastewater treatment cost contribution will be assessed in accordance with the rate schedule adopted as part of this chapter.
