MAPLETON CITY CORPORATION
SEWER USER CHARGE SYSTEM
The sewer use charge system is the mechanism used to assess fees to the users of the system. The use charge system is based on a residential equivalent (i.e., the flow and strength BOD on TSS of sewage equivalent to a single "normal" household).
Note that shaded numbers are given numbers. All other numbers are calculated.
A. NUMBER OF CONNECTIONS
Residential Users | 1300 |
Elementary School | 1 |
Churches | 4 |
Commercial and Small Business | 11 |
Cafe | 1 |
Public Buildings | 4 |
B. CURRENT FLOW PER RESIDENT
Average Daily Flow per Resident (Q) gallons/day | 400 |
Residential Equivalency Unit REU = 30 days/month x Q gallons/month | 12,000 |
Note: A residential equivalency unit (REU) is the quantity of wastewater generated by an average residence.
C. ESTIMATED AVERAGE FLOW FROM OTHER USERS
The second column RE (residential equivalents) rates the flow from a given establishment to the flows from a number of "normal" residences.
Usage gal/month | RE equivalents | |
Elementary School | 108,000 | 9 |
Churches | 24,000 | 2 |
Commercial and Small Business | 12,000 | 1 |
Cafe | 12,000 | 1 |
Public Buildings | 12,000 | 1 |
