below 250 mg/l and the BOD is established at or below 250 mg/l.
EASEMENT
An acquired legal right for the specific use of land owned
by others.
FLOATABLE OIL

or other entity.
pH
The logarithm of the reciprocal of the hydrogen-ion concentration.
The concentration is the weight of hydrogen ions, in grams, per liter
of solution. Neutral water, for example, has a pH value of 7 and a
hydrogen-ion concentration of 10.
PRETREATMENT
The treatment of wastewaters to remove or reduce the quantity
of one or more pollutants prior to discharge to the City wastewater
treatment works.
PROPERLY SHREDDED GARBAGE
The wastes from the preparation, cooking, and dispensing
of food that have been shredded to such a degree that all particles
will be carried freely under the flow conditions normally prevailing
in public sewers, with no particle greater than 1/2 inch (1.27 centimeters)
in any dimension.
PUBLIC SEWER
A common sewer controlled by a governmental agency or public
utility.
REPLACEMENT COST
Expenditures for obtaining and installing equipment, accessories
or appurtenances which are necessary to maintain the capacity and
performance during the service life of the treatment works for which
such works were designed and constructed. The term "operation and
maintenance" includes replacement.
SANITARY SEWER
A sewer that carries liquid and water-carried wastes from
residences, commercial buildings, industrial plants, and institutions
together with minor quantities of groundwater, stormwater, and surface
water that are not admitted intentionally.
SEWAGE
The spent water of a community. The preferred term is "wastewater."
SEWER
A pipe or conduit that carries wastewater or drainage water.
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 or flows during normal operation and
shall adversely affect the collection system and/or performance of
the wastewater treatment works.
SUSPENDED SOLIDS
Total suspended matter that either floats on the surface
of, or is in suspension in, water, wastewater, or other liquids and
that is removable by a standard glass fiber filter.
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 and would not be benefited by discharge to the sanitary
sewers and wastewater treatment facilities provided.
USER CHARGE
That charge to users of the treatment plant which adequately
provides for proportionate recovery of the operation and maintenance
costs.
WASTEWATER
The spent water of a community. From the standpoint of source,
it may be a combination of the liquid and water-carried wastes from
residences, commercial buildings, industrial plants, and institutions,
together with any groundwater, surface water, and stormwater that
may be present.
WASTEWATER FACILITIES
The structures, equipment, and processes required to collect,
carry away, and treat domestic and industrial wastes and dispose of
the effluent.

control plant."
