The intent of this Part is to:
A. Promote the general health, welfare and safety of the community.
B. Encourage the utilization of appropriate construction practices in
order to provide water for fire protection and domestic consumption
in the future.
C. Minimize danger to public health and safety by providing a public
water system for fire protection and domestic consumption.
D. Reduce financial burdens imposed on the community, its governmental
units and its residents by preventing the unwise design and construction
of public water systems that will not provide sufficient water for
fire protection and domestic consumption.
E. Specify minimum system sizes, flow rates, water storage capacity
and construction materials that shall be used in the design and construction
of a public water system.
F. Reduce the required parts inventory and increase the efficiency of
maintenance by requiring that each type of appurtenance or component
of the public water system be a standard design.
This Part, by reference, hereby incorporates the most recently
published edition of the following standards pertaining to design,
construction, testing and maintenance of public water systems as part
of this Part:
A. Standard Specifications and Details of Upper Makefield Township as
approved by separate resolution.
B. Public Water Supply Manual, Community System Design Standards, by
the Pennsylvania Department of Environmental Protection, Harrisburg,
Pa.
C. Guide for Determination of Needed Fire Flow by the Insurance Services
Office (ISO), as modified.
D. American Water Works Association Standards and Manuals by the American
Water Works Association, Denver, Colorado.
E. Additional standards incorporated by reference in the Standard Specifications
and Details, or as the Township Engineer may deem applicable to a
particular design and construction detail.
F. If more than one standard governs any item, then in that event, the
most stringent or highest standard shall apply.
All standards referenced are to be the latest revision thereof,
including future revisions and amendments.
Should a dispute arise concerning the interpretation of the
above standards as they relate to each other, or to the minimum standards
specified in this Part, an initial determination shall be made by
the Township Engineer. Any person who disagrees with the initial determination
made by the Township Engineer may seek a waiver of the standard by
submitting a written request to the Upper Makefield Township Board
of Supervisors.
As used in this Part, the following terms shall have the meanings
indicated:
DESIGN FLOW RATE
The Design Flow Rate for the public water distribution system
shall include the fire flow rate plus the maximum anticipated flow
rate for all other purposes.
FIRE FLOW RATE
The design fire flow rate shall be determined using the ISO
Guide for Determination of Needed Fire Flow, or this Part, whichever
is the greater.
PUBLIC WATER SYSTEM
One or more sources of water serving more than one user unit
(residence, business, church, school or combination thereof). All
public water systems shall be designed and constructed as dual-purpose
systems able to supply enough water for fire protection, while at
the same time meeting the anticipated consumption for other purposes.
RESIDENTIAL FLOW RATE
A.
The design residential average flow rate shall be 100 gallons
per day, per capita. The determination flow rate shall be based upon
four persons residing in each dwelling unit.
B.
All other flow rates shall be determined by the Township Engineer
pursuant to standard engineering practices for similar uses and shall
be approved by the Township Board of Supervisors.
USER UNIT
A single user of water such as a household, a business, a
church or a school.
All cold water meters in the public water system shall be furnished
and installed by the Township pursuant to the following:
A. A properly completed application for water service is filed on the
form prescribed by the Township.
B. The Township has received payment for all applicable charges and
fees.
C. The location of the water meter has been approved.
D. The service line has been installed from the distribution main to
the curb stop and to the building to be supplied with potable water
service, and the service line installation has been inspected by the
Township.
E. Installation of a meter insetter has been completed at the approved
meter location, or when determined by the Township to be necessary,
a meter pit has been installed at a location approved by the Township.
F. The Township has inspected the meter insetter or meter pit and verified
satisfactory installation in accordance with the Standard Specifications
and Details.
