The following charges are for the use and benefit of the facilities
afforded by the sanitary sewerage and drainage systems of the city
and regional sewerage facilities are to be collected from each person,
firm or corporation whose premises fall within the description of
premises to be charged as hereinafter set forth in this article. The
rates and fees provided herein are incurred charges or costs based
upon use or availability for use of the system. The nature of the
service provided and charged for is such that the individual property
owner is not able (and therefore not meeting a routine obligation
of ownership) to meet the requirements of sewage and sewer collection,
disposal and treatment if required, and the charges and service are
therefore necessary to enforce the regulations pertaining thereto
necessary to provide for the public health and safety as to sanitation,
communicable diseases and in guarding against the hazards of excess
surface and flowing water which cannot ordinarily be satisfactorily
or safely provided by individual citizens.
As used in sections
4.200 to
4.224, the following mean:
Access.
Easements across intervening property exist or can be conveniently
obtained and existing utilities and public facilities do not obstruct
connection to the sanitary sewer system.
Biochemical Oxygen Demand (BOD).
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure in five days
at 20 degrees Celsius expressed in milligrams per liter. This procedure
as set forth on “Standard Methods for the Examination of Water
and Wastewater.”
Collector Sewer.
A publicly owned and maintained conduit or pipe designed
and constructed to convey sewage from the property upon which the
sewage originates to a trunk sewer, and to which the service laterals
(sewer pipe between the building and collector sewer are permitted
to connect.
Drainage System.
A system of pipes, channels, ditches and other conduits designed
to collect and convey surface, ground and storm waters from both public
and private property to a legal point of discharge.
Dwelling Unit.
One or more habitable rooms which are occupied, intended
or designed to be occupied by one family with housekeeping facilities
for living, sleeping, cooking and eating.
Impervious Area.
The area of a tax lot or property which has been modified
so as not to allow or allow with great difficulty the movement of
surface water to the groundwater reservoir.
Local Sanitary Sewer System.
That portion of the publicly owned system of pipes and conduits
designed and constructed to collect and convey sewage from the property
of origin to the regional sewage system, and which are less than 24
inches in diameter. Pump and lift stations and other appurtenances
directly connected to pipes and conduits less than 24 inches in diameter
are also part of the local sanitary sewer system.
Operations and Maintenance.
Activities required to assure the dependable and economical
function of the sanitary sewer and drainage systems.
(1)
Maintenance. Preservation of functional integrity and efficiency
of equipment and structures. This includes preventative maintenance,
corrective maintenance and replacement of equipment as needed, including
the accumulation of reasonable reserves.
(2)
Operation. Control of the unit processes and equipment which
make up the sewerage works. This includes financial and personnel
management; records, laboratory control, process control, safety and
emergency operation planning.
Real Property.
The land and all building structures and improvements located
thereon. Regional Sewerage System. That portion of the publicly owned
sanitary sewer system consisting of pipes and conduits that are 24
inches and greater in diameter (including appurtenances connected
directly thereto) and treatment facilities that are designed and constructed
to receive, convey, treat and dispose of discharges from the local
sewer system.
Replacement.
Expenditures for obtaining and installing equipment, accessories,
or appurtenances which are necessary during the useful life of the
sanitary sewer and drainage systems to maintain the capacity and performance
for which such works were designed and constructed. The term “operation
and maintenance” includes replacement which is part of the actual
cost of the provision of continuous, dependable service.
Sanitary Sewer System.
The publicly owned system designed and constructed to receive,
convey, treat and dispose of sewage in accordance with federal and
state legislation.
Sanitary Sewer Users.
(1)
Residential. Single family, duplex and multiple family dwellings
assumed to have wastewater with a combined Biochemical Oxygen Demand
(BOD) and Suspended Solids (SS) concentration equal to or less than
400 milligrams per liter (mg/l).
(2)
Low strength. Commercial/industrial users with wastewater with
a combined BOD and SS concentration equal to or less than 400 milligrams
per liter (mg/l).
(3)
Medium strength. Commercial/industrial users with wastewater
with a combined BOD and SS concentration greater than 400 mg/l but
not greater than 800 mg/l.
(4)
High strength. Commercial/industrial users with wastewater with
a combined BOD and SS concentration greater than 800 mg/l but not
greater than 1200 mg/l.
(5)
Very high strength. Commercial/industrial users with wastewater
with a combined BOD and SS concentration greater than 1200 mg/l but
not greater than 1600 mg/l.
(6)
Super high strength. Commercial/industrial users with wastewater
with a combined BOD and SS concentration greater than 1600 mg/l.
Sewer User.
Any person making use of the drainage and/or sanitary sewer
system.
Single Family Dwelling.
Any dwelling designed or used exclusively for the occupancy
of one family and having housekeeping facilities for one family and
having a separate water supply.
Suspended Solids.
The total elements and compounds which float on the surface
of, or are suspended in wastewater, and which are removable by laboratory
filtration as determined by procedures specified in “Standard
Methods for Examination of Water and Wastewater.”
Useful Life.
The period during which a treatment works is planned and
designated to be operated.
User Charge.
A charge levied on users of the sanitary sewer and drainage
systems for the user’s proportionate share of the cost of operation
and maintenance (including replacement) based generally upon quantity
