12.20.340 Special adjustments. Revised 2/21 Revised 5/21

(A) Adjustments for Lawn Sprinkling or Other Situations Where the Town’s Water Meter Inaccurately Reflects Sewage Created.

(1) The quantity of water discharged into the sanitary sewerage system and obtained from sources other than the utility that serves the town shall be determined by the district in such manner as the district shall reasonably elect, and the sewage service shall be billed at the above appropriate rates. Further, as hereinafter provided in this section, the district may make proper allowances in determining the sewage bill for quantities of water shown on the records to have been consumed, but which are also shown to the satisfaction of the district that such quantities do not enter the sanitary sewage system.

(2) In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, water or other liquids into the district’s sanitary sewerage system, either directly or indirectly, is not a user of water supplied by the water utility serving the town, and the water used thereon or therein is not measured by a water meter, or is measured by a water meter not acceptable to the district, then the amount of water used shall be otherwise measured or determined by the district. In order to ascertain the rate or charge provided in this article, the owner or other interested party shall, at his expense, install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the district for the determination of sewage discharge.

(3) In the event a lot, parcel of real estate or building discharging sanitary sewage, industrial wastes, water or other liquids into the district’s sanitary sewerage system, either directly or indirectly, is a user of water supplied by the water utility serving the town and, in addition, is a user of water from another source which is not measured by a water meter or is measured by a meter not acceptable to the district, then the amount of water used shall be otherwise measured or determined by the district. In order to ascertain the rates or charges, the owner or other interested parties shall, at his expense, install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the district for the determination of sewage discharge.

(4) In the event a lot, parcel of real estate or building discharges sanitary sewage, industrial waste, water or other liquids into the district’s sanitary sewerage system, either directly or indirectly, and uses water in excess of 25,000 gallons per month, and it can be shown to the satisfaction of the district that a portion of water as measured by the water meter or meters does not and cannot enter the sanitary sewage system, then the owner or other interested party shall install and maintain meters, weirs, volumetric measuring devices or any adequate and approved method of measurement acceptable to the district for the determination of sewage discharge.

(B) Summer Consumption Protocol. There shall be a summer usage consumption protocol in order that single and two-family residential users of wastewater service shall not be unduly charged for sprinkling their lawns and other summer activities where higher consumption does not have a nexus to cost recovery and wastewater treatment.

(1) There is established a summer usage period which shall apply to single-family and two-family residential users. The summer usage period applies to metered usage beginning on the date the meter is read in June, July, August and September and ending on the date the meter is read in October.

(2) There is established a winter measurement period, which shall comprise the actual metered usage for November, December, January, February and March. An average consumption shall be calculated for the winter measurement period. The average shall be calculated by taking the sum of the actual metered consumption for a customer in the months of the winter period, and dividing the total metered usage by the five months. The average metered usage for the winter measurement period of a customer will be calculated as a single average metered consumption for the billing season to which it applies.

(3) During the summer usage period, charges for metered usage shall be based upon the lesser of either actual metered usage for period invoiced or the average metered consumption for the designated winter period.

(4) The superintendent of the utility and the billing authority (clerk-treasurer) shall jointly determine which bill(s) best reflect the metered usage intended to be captured during the summer usage period.

(5) The aforementioned provisions shall apply to each lot, parcel of real estate or building which is occupied and used as a single-family residence. Said provisions shall not apply to any premises which are partially or wholly used for multifamily, commercial or industrial purposes. In the event a portion of such premises shall be used for single-family residence, the owner shall have the privilege of separating the water service so that the residential portion of the premises is served through a separate meter and in such case the provisions hereunder shall be applicable to that portion of the premises used for residential purposes.

(6) In the event a single-family or two-family residential user for any reason has no actual or insufficient usage associated with the winter measurement period, the clerk-treasurer shall be authorized to make a reasonable determination for the average usage that shall be used in calculating the adjustment associated with the summer usage protocol.

(7) Allowances shall not be granted for the filling of swimming pools nor for irrigation outside the summer rate period.

(1) In order that the rates and charges may be justly and equitably adjusted to the service rendered to industrial users, the district shall base its charges not only on the volume, but also on strength and character of the stronger-than-normal domestic sewage and wastes which it is required to treat and dispose of. The district shall require the industrial user to determine the strength and content of all sewage and wastes discharged, either directly or indirectly into the sanitary sewage system, in such manner and by such method as the district may deem practicable in the light of the conditions and attending circumstances of the case, in order to determine the proper charge. The industrial user shall furnish a central sampling point available to the district at all times.

(2) Normal sewage domestic waste strength should not exceed a carbonaceous biochemical oxygen demand of 220 milligrams per liter of fluid or total suspended in excess of 260 milligrams per liter of fluid. Additional charges for treating stronger-than-normal domestic waste shall be made on the following basis:

(a) There shall be an additional charge of $1.822 per 100 pounds for total suspended solids received in excess of 260 milligrams per liter of fluid.

(b) There shall be an additional charge of $4.213 per 100 pounds of carbonaceous biochemical oxygen demand for CBOD received in excess of 220 milligrams per liter of fluid.

(3) The determination of suspended solids and five-day carbonaceous biochemical oxygen demand contained in the waste shall be in accordance with the latest copy of Standard Methods for the Examination of Water, Sewage and Industrial Wastes Method 5210.B, as written by the American Public Health Association, the American Water Works Association, the Water Environmental Association, and in conformance with Guidelines Establishing Test Procedures for Analysis of Pollutants, Regulation 40 CFR 136, published in the Federal Register on October 16, 1973, revised July 1, 2011.
