Section PSC 187.05 - Determining refund fees(1) Where the cost of the sewer main extension is to be collected through special assessment by the municipality against the abutting property, the procedures set forth under ss. 66.0701 and 66.0703, Stats., shall apply, and no additional contribution for the cost of the sewer main extension will be required and no refund will be made to the developer.(2) When a new sewer main is extended from an existing sewer main, which was not financed by developer contributions, the new sewer main extension shall not be subject to this chapter.(3) Where the developer is paying, or has paid, all or part of the cost of a sewer main extension, part of the contribution may be refundable. If a person whose property is outside of the development connects a sewer main extension to a developer-financed sewer main within three years after the date of completion of the developer's sewer main installation, within 60 days of connection the person shall pay to the developer the following: (a) Calculation of sewer main extension refund. The developer shall be refunded a percentage of the costs of the original sewerage project calculated using the Diameter Squared, Length of Sewer Main method, where Refund ($) = C × P
C = the cost or portion of the cost of the original sewerage project paid or to be paid by the developer ($)
P = [L2 × (D2)2 ] ÷ [L1 × (D1)2]; when P >= 0.50, set P = 0.50 (i.e. P may never be greater tha n 0.50 in calculating the refund)
L1 = Lineal feet of sewer main installed with the original sewerage project
D1 = Diameter in inches of sewer main L1
L2 = Lineal feet of sewer main installed with new sewer main extension
D2 = Diameter in inches of sewer main L2
Note: Where multiple sewer main diameters are involved, calculating "P" requires summing the individual products of each length of sewer main multiplied by its respective diameter squared.
(b) Calculation of additional sewer main extensions. As additional sewer main extensions are made to the sewer main, paid or to be paid by the developer, the cost of the original sewerage project shall be redistributed on the basis of proportionality by expanding the Diameter Squared, Length of Sewer Main Method to include the additional extensions. Any calculations previously made under the formula shall be recalculated to adjust and determine new reimbursement payments to all parties. Reimbursement to the original developer shall never exceed 50% of the original sewerage project cost. No refunds will be made for sewer main extensions that do not directly connect to the sewer mains serving the original development.Wis. Admin. Code Public Service Commission PSC 187.05
