■ Distribution of costs to billable parameters and customer classes shown in the preceding section is followed by the calculation of rates and monthly charges in this section. The current wastewater rate structure has been in place since 2010. The term "rate structure" refers to the selection of customer classes and corresponding Flow, BOD and SS assignments and the type of rate applied to recover costs - volumetric (in units of $/hcf, for example) or fixed (in units of $/month, for example). Recommended changes to the rate structure are described below. Apply the "Account/Billing Unit Charge" Separately from the Flow/BOD/SS Rate for Commercial and Institutional Customer Classes. Currently, there is an account charge applied to the monthly bill for account in the Industrial User customer class. Account charges for the Residential customer class are added to the monthly charge. Account charges for the Commercial and Institutional customer classes are added to the volumetric charge. By adding the account charges to the volumetric charge (instead of collecting it separately or added to the monthly charge), each subclass in the Commercial and Institutional customer classes pays a different portion of the account charge revenue requirements. It is recommended that the same Account/Billing Unit charge be applied to every monthly bill in addition to the portion of the monthly bill with the Flow/BOD/SS charges. For the Residential customer class, the monthly charge has three components: 1) account/billing unit costs; 2) Flow, BOD and SS costs; and 3) 1/1 costs. Development of the monthly charge for both Single Family accounts and for Multiple Family accounts is shown in Appendix E, Table E-1. For the Commercial and Institutional customer classes, the monthly charge has two components: 1) account/billing unit costs; and 2) Flow, BOD, SS and 1/1 costs. The Flow, BOD, SS and 1/1 costs are recovered through a volumetric charge which varies based on the BOD and SS characteristics of each account. Development of the rates and monthly charges for Commercial and Institutional customer classes is shown in Appendix E, Table E-2. Monthly charges for each billable parameter are calculated by multiplying the unit cost for each parameter (listed in Table 4-2) by the amount of discharge for each parameter and the number of accounts. 5-1 11 H/14 I Nji iu vicYY 111, ,^ a ^:. ci,d/ VIsc c4 ;oi,dci'ds ci,i V h " -Ih eV Is-11h'ju; ; NjI Yric III IIIV ,fl ci,Is -po,iiia ,I a Y ric a rIG c4 Y his ulorolIIiiu;i^d,
