(A) Due to the nature of the town’s existing residential and commercial users, the B.O.D., suspended solids and other pollutant concentrations discharged by all the users are approximately equal. Therefore, the user charges developed by this section are done so on a volume basis.
(B) The town shall reasonably estimate the average daily volume of wastewater which each user discharges to the wastewater system. This average volume shall then be divided by the total average daily volume of wastewater discharged to the wastewater system to determine each user’s volume contribution percentage.
(C) The volume contribution percentage will be calculated by using multipliers for the various types of users. Residential users will be considered to be the class of user with a multiplier of 1.0. Commercial users will be assigned multipliers according to the ratio of their estimated wastewater volume contribution to the estimated volume contribution of an average residential user. In the case of the following commercial establishments, multipliers are provided as approximate ratios of commercial volume to average residential volume.
Commercial Establishment | Multiplier |
Commercial Establishment | Multiplier |
Apartment building | 1.0/apartment |
Car wash | 1.75/2 bays |
Grocery store | 1.0 |
Laundromat | 2.0/10 washers |
Motel or hotel | 2.5/10 units |
Other | ** |
Restaurant, café or tavern | 1.0 |
Service station | 1.0 |
Service station with car wash | 2.5 |
School | 5.0/100 students |
Small, dry business* | 1.0/20 employees |
*A small, dry business is defined as being a business with 20 employees or less and whose wastewater discharge is limited to sanitary facilities for employees only. | |
**Rate shall be as reasonably determined by the town based on this subchapter. | |
The multipliers are used to calculate each user’s contribution percentage by dividing the sum of the multipliers into each user’s multiplier. This will yield the estimated percentage of volume contributed by each user. | |
(D) Industrial users, for the purposes of this subchapter, are defined as follows.
(1) Any non-governmental, nonresidential user of a publicly owned treatment works which discharges more than the equivalent of 25,000 gallons per day (gpd) of sanitary wastes and which is identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemented under one of the following divisions:
(a) Division A, Agriculture, Forestry and Fishing;
(b) Division B, Mining;
(c) Division D, Manufacturing;
(d) Division E, Transportation, Communications, Electric, Gas and Sanitary Services; and
(e) Division I, Services.
(2) A user in the divisions listed may be classified commercial if it is determined that it will introduce primarily segregated domestic wastes or wastes from sanitary conveniences. Future establishment of any industry which will introduce other than the above-mentioned types of wastes into the town’s system shall necessitate revision of this subchapter.
