[HISTORY: Adopted by the Board of Supervisors
of the Township of Upper Uwchlan as indicated in article histories.
Amendments noted where applicable.]
[Adopted 10-17-1988 by Ord. No. 88-04]
The purpose of the provisions of this article
are to:
A.
Insure that each dwelling unit and each commercial
or industrial building in all subdivisions and land developments hereafter
granted approval shall have an adequate supply of potable water for
domestic use; and
B.
Insure that each unit or building shall have an adequate
supply of water for purposes of fire protection; and
C.
Insure that in each case where water is to be supplied
to a subdivision or land development by means of a public water supply
system, such system meets minimum standards controlling water storage
and production capabilities for domestic and fire use for the protection
of the health, safety and welfare of all Township residents.
All land developments within the franchise area
of a public water company and all of that area within 1,500 feet of
a water supply main operated by a water company in Upper Uwchlan Township
should be serviced by public water which shall be provided by a public
utility organized and operating under the laws of the Commonwealth
of Pennsylvania or by a municipal authority or other municipal corporation
organized and operating under the laws of the Commonwealth of Pennsylvania.
If the applicant for subdivision or land development
approval proposes that the subdivision or land development be served
by public water, the applicant shall submit, upon submission of the
preliminary plan, seven copies of documentation which shall be designated
as "proposed public water supply study" which shall contain the following
information:
A.
The name, address and telephone number of the proposed
public water supplier (company, water company or public utility) proposed
by the applicant to supply water to the subdivision or land development.
B.
A complete description of the source of the water
supply, the quantity and quality of the water available from that
source and the capacity of all reservoirs and their locations.
C.
If wells are to be utilized as part of the supply
system, the number of wells, pumping capacity of each well, the number
of hours per day that each well pump operates, diameter of well casing,
draw-down rated capacity of each well, and the maximum sustained yield
from the well test together with a copy of the well test data.
D.
Size of the water mains to be utilized in the proposed
subdivision or land development, size of all water mains on the system
proposed to service the subdivision or land development, the number
of existing fire hydrants on the system and the number of fire hydrants
proposed for the new subdivision or land development.
E.
The number of residential customers on the existing
system proposed to service the subdivision or land development and
the number of gallons required to service the existing system as of
the supplier's last billing.
F.
The number of commercial and industrial customers
on the existing system proposed to service the subdivision or land
development and the number of gallons required to service the system
as of the supplier's last billing.
G.
Fire hydrant test results made by the Insurance Services
Office of Pennsylvania for the existing system proposed to service
the subdivision or land development. In the event the system has been
expanded to service additional customers since the date of the last
test, applicant shall set forth the number of new customers, designating
them as residential, commercial or industrial, as applicable, additional
gallonage required to service those customers and the number of additional
hydrants installed on the system.
H.
A description of the service area of the public water
supplier, and, if regulated by the Public Utilities Commission of
the Commonwealth of Pennsylvania, whether the proposed subdivision
or land development is within the supplier's approved franchised area.
Public Utility Commission approval to a public water company to extend
any franchise area to include the proposed subdivision or land development
shall be a condition precedent to subdivision or land development
approval.
The proposed public water supply study submitted
by the applicant shall be reviewed by the Township Engineer in conjunction
with the subdivision or land development application process and he
shall make a recommendation to the Board of Supervisors with respect
to the applicant's compliance with the section. The applicant must
bear the cost of Township engineering review and report and agrees
to pay the cost thereof by submission to the Township of a subdivision
or land development application. Submission by the applicant of a
complete "proposed public water supply study" is essential and no
subdivision or land development application, whether preliminary or
final, shall be granted approval without such submission.
In all subdivisions and land developments served
by public water, the following water pressure and gallonage requirements
shall apply:
A.
Residential use.
(1)
A minimum domestic pressure of 30 pounds per square
inch shall be provided at each house to be connected to the water
main. The system to which the residential unit is connected shall
have sufficient capacity to supply a minimum of 300 gallons of water
per residential unit per day within the subdivision or land development.
(2)
For purposes of fire protection in residential districts,
the system shall be demonstrably capable of providing fire flow water
requirements for a minimum duration of two hours of not less than
500 gallons per minute at residual pressures of 20 pounds per square
inch or more as required for ISO certification.
B.
Commercial or industrial use.
(1)
A minimum pressure of 30 pounds per square inch shall
be provided at each commercial or industrial building connected to
the water supply main. When a builder wishes to connect to a public
water system, a study will be made to determine if there is adequate
water to supply system to supply the building and use.
(2)
For purposes of fire protection in commercial and
industrial districts, 1,000 GPM at 20 psi residual pressure is required
or as required for ISO certification.
No subdivision or land development application
proposing a public water supply system shall be granted preliminary
or final approval unless the applicant demonstrates by a fair preponderance
of the credible evidence full compliance with the provisions of this
article.
A.
Water mains shall be constructed of the cement-lined,
ductile iron, minimum class 52 pipe or as approved by the Township
Engineer. No extension of water mains shall be permitted for a pipe
having a diameter of less than six inches.
B.
All pipe shall have a minimum cover of three feet
six inches from grade to the crown of pipe.
C.
Generally, water mains shall be so designed as to
form a loop system to enhance the continual supply of fresh water.
When dead ends occur on new mains, they shall all be closed with cast-iron
plugs and caps, with a blowoff valve, with a concrete anchor, or fire
hydrant.
D.
Mains shall be drained through drainage branches or
blowoffs to dry wells from which the water can be pumped. Drainage
branches, blowoffs, air vents, and appurtenances shall be provided
with valves.
E.
Blowoffs shall not be connected to any sewer, or submerged
in any manner that will permit back siphonage in the distribution
system. All blowoffs should be located out of paving.
F.
Valves in water mains shall, where possible, be located
on the street property lines extended. A cast-iron valve box or a
masonry pit shall be provided for every valve which has no gearing
or mechanism, or for which the gearing or operating mechanism is fully
protected with a cast-iron grease case. A masonry valve pit shall
be provided for every valve which has exposed gearing or operating
mechanisms.
G.
Manholes shall be constructed of brick or concrete,
with cast-iron frames and covers or as approved by the Township Engineer.
H.
Fire hydrants shall be provided as an integral part
of any public water system. They shall be located no farther than
