[Amended by Ord. No. A-528-89, 1989; at time of adoption of Code (see Ch. 1.01, Code Adoption)]
Sewer users served by Utility water meters. There is levied and assessed upon each lot, parcel of land, building or premises having a connection with the wastewater collection system and being served with water solely by the Water Utility, a sewer service charge based, in part, on the quantity of water used, as measured by the Water Utility water meter used upon the premises.
Sewer users served by private wells. If any person discharging wastewater into the sanitary sewers procures any part or all of his water from sources other than the Water Utility, all or part of which is discharged into the sanitary sewers, the person shall have water meters installed by the Water Utility at the person's expense for the purpose of determining the volume of water obtained from these sources. Where sewer meters are already installed, water meters will not be required. The water meters shall be furnished by the Water Utility and installed under its supervision, all costs being at the expense of the person requiring the meter. The Water Utility will charge for each meter a rental charge set by the Water Utility to compensate for the cost of furnishing and servicing the meter. The rental charge shall be billed at the time the sewer service charge is billed.
Deduct meters. If a person feels that a significant amount of metered water does not reach the sanitary sewer, he can at his own expense, with approval of the approving authority, install such additional meters or metered services as are necessary to calculate the volume of water not discharged to the sanitary sewer. Metered water not discharged to the sanitary sewers shall not be subject to sewer service charges. Requests to install additional meters must be made in writing to the approving authority.
Sewerage service rendered by the Water/Wastewater Utility shall be paid for at the current rates and charges in effect and as approved by the Village Board; description of various rate components is as follows:
General sewer service. Metered.
Quarterly service charge. This is a fixed quarterly charge that applies on a meter size basis to all metered customers discharging domestic strength sewage up to 200 mg/l per liter BOD, 250 mg/l per liter suspended solids, 6 mg/l per liter for phosphorus and 20 mg/l per liter for nitrogen.
Volume charge. A volume charge applies for each 1,000 gallons domestic strength sewage discharged to the sanitary sewer system.
Editor's Note: Original § 12.08.090A.3, Sprinkling credit for residential customers, which immediately followed this subsection, was repealed 11-19-2012 by Ord. No. 0011-2012.
High strength sewer service, metered. Where the strength of any contributor exceeds the strength limitations of 200 milligrams per liter for BOD, 250 milligrams per liter for suspended solids, six milligrams per liter for phosphorus and 20 milligrams per liter for nitrogen, a periodic sampling shall be taken and wastewater analyzed to determine the strength of said waste which will be billed at the high strength rates currently in effect.
[Amended by Ord. No. 035 Series 2002; Ord. No. 008, Series 2003]
Reassignment of sewer users. The approving authority will reassign sewer users into appropriate sewer service charge categories if wastewater flow monitoring and sampling programs or other related information indicate a change of categories is necessary.
General sewer service unmetered. This rate shall be applied only to single-family residential and small commercial customers and approximates the cost for 18,000 gallons per quarter discharged to the sewer system. If it is determined by the Utility that the user discharges more than 18,000 gallons per quarter to the system, an additional charge of the effective rate per 1,000 gallons will be made for estimated additional usage.
[Amended by Ord. No. 035 Series 2002; Ord No. 008, Series 2003]
