The meaning of terms used in this article shall be as follows:
BOD (biochemical oxygen demand).
The quantity of oxygen by weight, expressed in mg/l, utilized
in the biochemical oxidation of organic matter under standard laboratory
conditions for five (5) days at a temperature of twenty degrees (20°)
centigrade.
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 five feet outside the inner face of the building wall.
Building sewer.
The extension from the building drain to the sewer or other
place of disposal (also called house lateral and house connection).
City.
The City of Yorktown, Texas or any authorized person acting
in its behalf.
COD (chemical oxygen demand).
A measure of the oxygen-consuming capacity, expressed in
mg/l, of inorganic and organic matter present in water or wastewater.
It is expressed as the amount of oxygen consumed from a chemical oxidant
in a specific test. It does not differentiate between stable and unstable
organic matter and thus does not necessarily correlate with biochemical
oxygen demand.
Domestic wastewater.
Water-borne wastewater normally discharging into the sanitary
conveniences of dwellings (including apartment houses and hotels),
office buildings, factories, and institutions.
Garbage.
Animal and vegetable wastes and residue from the preparation,
cooking, and dispensing of food, and from the handling, processing,
storage and sale of food products and produce.
Industrial waste.
Water-borne solids, liquids, or gaseous wastes resulting
from and discharged, permitted to flow, or escaping from an 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 wastewater, or distinct from normal domestic wastewater.
Milligrams per liter (mg/l).
Means the same as parts per million, and is a weight-to-volume
ratio; the milligram-per-liter value multiplied by the factor 8.34
shall be equivalent to pounds per million gallons of water.
Natural outlet.
Any outlet into a watercourse, ditch, lake, or other body
of surface or ground water.
Normal domestic wastewater.
Normal wastewater for the city in which the average concentration
of suspended solids and 5-day BOD is established at not more than
250 mg/l of each.
Person.
Any and all persons, natural or artificial, including any
individual, firm, company, industry, municipal or private corporation,
association, government agency, or other entity and agents, servants,
or employees.
pH.
The logarithm (base 10) of the reciprocal of the hydrogen
ion concentration.
Properly shredded garbage.
The wastes from the preparation, cooking, and dispensing
of food that have been shredded to such degree that all particles
shall be carried freely under the flow conditions normally prevailing
in public sewers, with no particles greater than one-half (1/2) inch
in any dimension.
Public sewer.
A sewer in which all owners of abutting properties shall
have equal rights and the use of which is controlled by the city.
Sanitary sewer.
A sewer that conveys domestic wastewater or industrial wastes
or a combination of both, and into which storm, surface, and ground
waters or unpolluted wastes are not intentionally passed.
Sewer.
A pipe or conduit that carries wastewater or drainage water.
Slug.
Any discharge of water, wastewater, or industrial waste which,
in concentration of any given constituent or in quantity of flow,
exceeds for any period of duration longer than fifteen (15) minutes
more than five (5) times the average twenty-four (24) hour concentration
or flows 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 Public Health Association, the American Water
Works Association, and the Water Environment Federation.
Storm sewer or storm drain.
A sewer which carries storm and surface waters and drainage
but excludes domestic wastewater and polluted industrial wastes.
Stormwater.
Rainfall or any other form of precipitation.
Superintendent.
The water and wastewater superintendent of the city or his
duly authorized deputy, agent, or representative.
Suspended solids.
Solids that either float on the surface of, or are in suspension
in, water, wastewater, or other liquids, and which are largely removable
by a laboratory filtration device.
Unpolluted water or waste.
Water or waste containing none of the following: free or
emulsified grease or oil; acids or alkalis; phenols or other substances
producing taste or odor in receiving water; toxic or poisonous substances
in suspension, colloidal state or solution; and noxious or otherwise
obnoxious odorous gases. It shall contain not more than ten (10) mg/l
each of suspended solids and BOD. The color shall not exceed fifty
(50) color units as measured by the platinum-cobalt method of determination
as specified in Standard Methods.
Wastewater.
A combination of the water-carried waste from residences,
business buildings, institutions, and industrial establishments, together
with such ground, surface, and storm water that may be present.
Wastewater facilities.
All facilities for collection, pumping, treating, and disposing
of wastewater and industrial wastes.
Wastewater treatment plant.
Any city-owned facilities, devices, and structures used for
receiving and treating wastewater, industrial waste, and sludges from
the city wastewater facilities.
Watercourse.
A natural or man-made channel in which a flow of water occurs,
either continuously or intermittently.
