A sewer intended to receive both wastewater and stormwater or surface
water.
COMPATIBLE POLLUTANTS
Those pollutants generally characterized as BOD, suspended solids, pH and fecal coliform, together with any additional pollutants defined in the WPDES permit issued for the joint treatment facilities, unless the concentrations of any of these pollutants are such that they interfere with the operation of the treatment works or exceed the limits established under Articles

established at or below 250 milligrams per liter.
INDUSTRIAL USER AS DEFINED FOR INDUSTRIAL USER CLASS

or appurtenances which are necessary to maintain the capacity and performance
during the service life of the treatment works and Village sewerage system.

any applicable surcharge.
SLUG
Any discharge of water or wastewater which, in concentration of any
given constituent or in quantity of flow, exceeds, for any period of duration
longer than 15 minutes, more than five times the average twenty-four-hour
concentration of flows during normal operation and which adversely affects
the collection system and/or performance of the wastewater treatment plant.
STANDARD METHODS
The examination and analytical procedures set forth in the most recent
edition of Standard Methods for the Examination of Water, Sewage and Industrial
Wastes, published jointly by the American Public Health Association, the American
Waterworks Association and the Water Pollution Control Federation.
STORM SEWER
A sewer which carries storm and surface drainage but excludes domestic
wastewater and industrial wastes.
SURCHARGE

a laboratory filtration device. Quantitative determination of suspended solids
shall be made in accordance with procedures set forth in Standard Methods.
UNPOLLUTED WATER
Water of quality equal to or better than the effluent criteria in
effect, or water that would not cause violation of receiving water quality
standards.
USAGE CHARGE
That charge to users of the wastewater treatment plant which adequately

administrative and billing costs associated with the activities of the Sauk
