(a) Domestic.The user charge fee for domestic customers shall be based on the model no. 1 formula:
Cu= Ct____ Vt(Vu)
A typical residential customer’s bill is available in the town offices for review.
(b) Industrial.The user charge for industrial customers shall be calculated in the same manner as domestic customers unless pollutant loadings are above the baseline pollutant concentrations established in section 36-158. Where so determined, a surcharge, added to the base charge (calculated by model no. 1) shall be levied. The formula used in calculating the surcharge is the same as model no. 2, i.e.:
C s = B c (B) + S c (S) + N c (N) = P c (P) V u
Table 1 also presents calculations for a typical industrial user’s bill and surcharges. (Ord. of 4-5-93, § X(2))
