(4) Single-unit residential property.
(b) Theft of Service.
(1) A corrected bill shall be issued for illegal water/sewer usage, including straight pipe connections, stolen or damaged meters, and meter bypasses left open, during the period for which WSSC can reasonably determine the charges.
(2) The corrected bill shall be based on the property’s comparable ADC or, if unavailable, the current ADC immediately after the illegal connection has been removed.
(c) Incorrect Service.
(1) A bill or bills issued on the basis of a service other than that actually provided the property shall be corrected for no more than the previous 12 months, if the correction results in a bill increase.
(2) If the correction results in a bill decrease, WSSC shall adjust incorrect charges for a period of not to exceed three years from the date that WSSC discovered the incorrect service.
(3)
(i) For example, bills issued for water use only to a property receiving both water and sewer service shall be corrected to include sewer use charges calculated on the basis of the property’s billed water use, for a period not to exceed 12 months.
(ii) Bills issued for water and sewer service to a property actually receiving only water service shall be corrected to exclude sewer charges for up to three years.
(d) Over-Registering Meter (Residential or Commercial, Single- or Multi-Unit).
(1) A bill or bills issued on the basis of a reading from a meter that is subsequently found to be an over-registering meter shall be corrected for a period not to exceed three years.
(2) The corrected bills(s) shall be issued on the basis of the property’s ADC immediately following the meter’s repair or replacement.
(e) Under-Registering Sub-Meter.
(1) A bill rendered on the basis of a reading from an under-registering sub-meter or its remote reading device shall be corrected for a period of no more than three years.
(2) The corrected bill(s) shall be based on the average daily sewer use before the sub-meter or its remote reading device began to malfunction or, if unavailable, the current average daily sewer uses immediately following the sub-meter’s repair or replacement.
