The director of the department of water and sewerage services and director of finance
are authorized to establish a system of partial payments for tapping and capacity
charges created by this chapter for customers using four-inch, six-inch and eight-inch
sanitary sewer connections with expected sewer effluent averaging five thousand gallons
per day or less. Eligible customers shall be allowed to make payment in thirty-six
equal monthly installments, without interest, from the date of connection. Upon request,
the director shall review the account of each eligible customer on or about the first
anniversary of the establishment of the account to determine the customer's actual
capacity requirement. In the event that the actual capacity requirement differs by
ten percent or more from the capacity estimate used at establishment of the account
to determine the capacity charge created by this chapter, the director shall refund
to or collect from the customer, as appropriate, the difference between the capacity
charge previously paid by the customer and the capacity charge calculated on the customer's
actual capacity requirement. The director further shall amend the terms of any payment
plan contemplated in this section as necessary to cause the total capacity charge
paid by an eligible customer to be based on the customer's actual capacity requirement.
A copy of this section of the Metropolitan Code shall be made available to any customer
entering into a payment plan hereunder. This section shall not apply to single-family
residential developments or to combined single-family and commercial developments.
