[Added 9-16-2002 by Ord. No. HR-310]
WATER COMPANY
That private or public water company providing water service
to the customer.
The requirements of this section shall apply
to each customer of the sewer system whose sewer rental is based upon
the amount of water used.
A. Methods of measuring volume.
(1) Whenever a person discharges domestic and/or industrial
waste into the sewer system, in cases where all of the water used
is obtained from the water company, the volume of water to be used
in computing the sewer rental shall be the volume of water company
water used, as determined from meter readings, during the billing
period.
(2) In cases where persons have sources of water supply
in addition to or other than the water company and discharge domestic
waste and/or industrial waste into the sewer system, those persons
shall permit the Township to install a meter on such additional or
other source of supply. The total amount of water consumed, as shown
by these meter readings, will be used in computing the sewer rentals.
(3) In cases where persons use water from the water company
and/or from an independent supply such that all or any part of the
water so used is not discharged into the sewer system, the quantity
of water used to determine the sewer rentals shall be computed by
one of the following methods:
(a)
Method No. 1: By placing a meter or measuring
device on the sewer connection to each structure being served. The
readings from this meter or measuring device shall be used in computing
the sewer rentals.
(b)
Method No. 2: By placing a meter or measuring
device on the effluent not discharging into the sewer system. The
reading from this meter or measuring device will then be deducted
from the total water meter readings and the remainder will be used
in computing the sewer rentals.
(c)
Method No. 3: When, in the opinion of the Sewer
Manager, it is not practical to install measuring devices to determine
continuously the quantity of water discharged or not discharged into
the sewer system, the Sewer Manager will determine, in such manner
and by such method as he may prescribe, the percentage of total water
used which is discharged into the sewer system and the quantity of
water used to compute the sewer rentals shall be the percentage so
determined. Any dispute as to the percentage of such discharge determined
by the Superintendent of the Sewer Department shall be submitted to
the Board of Supervisors, whose decisions on the matter shall be final
for the current calendar year.
B. Measuring devices. All meters or measuring devices
required to be used under provisions of these rules and regulations
except those provided by the water company shall be furnished and
installed by the Township at the expense of the property owner. All
such meters or measuring devices (except those provided by the water
company) shall be under the control of the Township and may be tested,
inspected or repaired by the Township employees whenever the Sewer
Manager shall deem necessary. The owner of the property upon which
such measuring device is installed shall be responsible for its maintenance
and safekeeping, and all repairs thereto shall be made by the Township,
at the property owner's expense, whether such repairs are made necessary
by ordinary wear and tear or other causes. Bills for such installation
and repairs shall be due and payable at the same time and collected
in the same manner as are the bills for sewer services; such bills
from and after their due date shall constitute a lien upon the property
upon which such measuring device is installed.
C. Meter readings. All meter or measuring devices shall
be made available to Township employees for meter reading at any reasonable
time.
[Amended 11-16-1987 by Ord. No. HR-113; 10-16-1991 by Ord. No. HR-131; 9-16-2002 by Ord. No. HR-310]
A. Imposition of sewer and utility rent or charge. There
is hereby imposed upon each property located within the limits of
the Township served by the sewer/utility system and having the use
thereof, sewer/utility service district rents or charges payable as
hereinafter provided, for the use, whether direct or indirect, of
the system, based on the current utility rental rate, as set forth
in Schedule A, attached hereto, and the Schedule of Equivalent Dwelling
Unit (EDU) values, as set forth in Schedule B, attached hereto.
B. Certifications. Periodic certifications as to factors
upon which the aforesaid EDU determinations are to be computed may
be required by the Township from owners of property served or to be
served by the sewer/utility system.
C. Changes in classification, additional classifications
and modifications. If use or classification of any property should
change within any six-month period, the difference in rental, prorated
on a monthly basis to the nearest calendar month, will be charged
or credited, as the case may be, on the bill for the succeeding six-month
period. Additional classifications and additional utility rentals
may be established by the Township from time to time.
D. Time and method of payment. Rentals or charges shall be paid annually. Billings for utility rentals shall be made each year, for the prior full calendar year period immediately preceding the date of the bill. The bills for utility rentals under §
163-7, Subsection
A, for the utility billing period during which a property is not connected to the system for a full twelve-month period will be prorated on the basis of the annual rate. All bills shall be due and payable on their respective dates.
No person shall maliciously, willfully or negligently
break, damage, destroy, uncover, deface or tamper with any structure,
appurtenance or equipment which is a part of the municipal sewage
works.
The Township Engineer and other duly authorized
employees of the Township bearing proper credentials and identification
shall be permitted to enter upon all properties for the purposes of
inspection, observation, measurement, sampling and testing, in accordance
with the provisions of this article.
