herein are defined as follows:
APPROVING AUTHORITY
The County Engineer (or other official designated by the
County) of the County of Carroll or his duly authorized deputy, agent
or representative.
BOD (denoting "biochemical oxygen demand")
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure in five days
at 20° C., expressed in parts per million. The laboratory determination
shall be made in accordance with the procedures set forth in Standard
Methods.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system
which receives the discharge from soil, waste and other drainage pipes
inside the walls of the building and conveys it to the building sewer
beginning three feet outside the inner face of the building wall.
BUILDING SEWER
The extension from the building drain to the sewer or other
place for disposal.
DOMESTIC SEWAGE
Waterborne wastes normally discharging from the sanitary
conveniences of dwellings (including apartment houses and hotels),
office buildings, factories and institutions, free from storm surface
water and industrial wastes.
ENGINEER
The County Engineer or the County's consulting engineer or
their duly authorized representative.
GARBAGE
Solid wastes and residue from the preparation, cooking and
dispensing of food and from the handling, storage and sale of food
products and produce.
INDUSTRIAL WASTES
All waterborne solids, liquids or gaseous wastes resulting
from any industrial, manufacturing or food-processing operation or
process or from the development of any natural resource or any mixture
of these with water or domestic sewage, as distinct from normal domestic
sewage.
NATURAL OUTLET
Any outlet into a watercourse, pond, ditch, lake or other
body of surface water or groundwater.
NORMAL DOMESTIC SEWAGE
Normal sewage for the County of Carroll, in which the concentration
of suspended materials and five-day, twenty-degree-centigrade BOD
is established at 240 parts per million each, by weight, on the basis
of the normal daily contribution of 0.20 pound per capita, per 100
gallons.
PARTS PER MILLION
A weight-to-weight ratio; the parts per million value multiplied
by the factor 8.345 shall be equivalent to pounds per million gallons
of water.
PERMITTEE
That person applying for a permit to construct a sanitary
sewer main or to connect to an existing sanitary sewer.
PERSON
Any and all persons, natural or artificial, including any
individual, firm, company, industry, municipal or private corporation,
association, society, governmental agency or other entity and his
or its agents, servants or employees.
pH
The logarithm (base 10) of the reciprocal of the hydrogen
ion concentration of a solution. It shall be determined by one of
the procedures outlined in Standard Methods.
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 under the flow conditions normally prevailing in public
sewers, with no particle greater than 1/2 inch in any dimension.
PUBLIC SEWER
Either a sanitary or storm sewer in which all owners of abutting
properties shall have equal rights and which is controlled by public
authority.
SANITARY SEWER
A sewer which carries sewage and to which stormwater, surface
water and groundwater are not intentionally admitted.
SEWAGE
A combination of water-carried waste from residences, business
buildings, institutions and industrial establishments, together with
such groundwater, surface water and stormwater as may be present.
SEWAGE WORKS
All facilities for collecting, pumping, treating and disposing
of sewage.
SEWER
A pipe or conduit for carrying sanitary sewage.
SEWERAGE
The system of sewers and appurtenances for the collection,
transportation and pumping of sewage and industrial wastes.
SEWER SERVICE CHARGE
The charge made on all users of the public sewerage system
whose wastes do not exceed in strength the concentration values established
as representative of normal sewage.
SLUG
Any discharge of water, sewage or industrial waste 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 more than
five times the average twenty-four-hour flow during normal operation.
STANDARD METHODS
The examination and analytical procedures set forth in the
latest edition, at the time of analysis, of Standard Methods for the
Examination of Water and Wastewater, as prepared, approved and published
jointly by the American Water Works Association, the Water Pollution
Control Federation and the American Public Health Association.
STORM SEWER or STORM DRAIN
A sewer which carries stormwater and surface water and drainage
but excludes sewage and polluted industrial wastes.
STORMWATER RUNOFF
That portion of the rainfall that is drained into the storm
sewers.
SURCHARGE
The charge in addition to the published water and sewer rates.
The basis for surcharges on industrial wastes is a capital and operating
cost for suspended solids, BOD and chlorine demand exceeding normal
domestic sewage.
SUSPENDED SOLIDS
Solids that either float on the surface of or are in suspension
in water, sewage or other liquids and which are removable by laboratory
filtering. Quantitative determination of suspended solids shall be
made in accordance with procedures set forth in Standard Methods.
UNPOLLUTED WATER OR WASTE
Any water or waste containing none of the following: free
or emulsified grease or oil, acid or alkali; phenols or other substances
imparting taste and odor in receiving water, toxic poisonous substances
in suspension, colloidal state or solution; and noxious or odorous
gases. The water shall contain not more than 10 parts per million
each of suspended solids and BOD. The color shall not exceed 150 jackson
turbidity units.
WATERCOURSE
A channel in which a flow of water occurs, either continuously
or intermittently.
