52 Pa. Code § 65.17 - Standards of design
(a)
General. The design of the water plant of the utility shall
conform to standard acceptable engineering practices. It shall be designed so
as to provide reasonably adequate and safe service to its customers and shall
conform to the requirements of the Department of Environmental Resources which
concern sanitation and potability of water.
(b)
Distribution system. The
distribution system shall be of adequate size and so designed in conjunction
with related facilities as to maintain the minimum pressures required by §
65.6 (relating to pressures). Pipe
of a diameter of less than 6 inches shall not be used for distribution mains
except in cul-de-sacs where the mains are not subject to being extended and are
not more than 250 feet in length.
(c)
Transmission systems. In
combination with related storage facilities, transmission pipelines from
sources of supply shall be designed to deliver to the limits of the capacity of
those sources of supply the minimum foreseeable requirements, as determined
pursuant to good engineering practices, of that portion of the system which is
dependent upon such transmission pipelines.
(d)
Company's service lines.
The size, design, material and installation of the service pipe shall conform
to the reasonable requirements of the utility; provided, however, that the
minimum size of the pipe shall not be less than 3/4 inch.
(e)
Water supply
requirements. The quantity of water delivered to the distribution
system from total source facilities should be sufficient to supply adequately,
dependably and safely the total requirements of all customers under maximum
consumption and should be determined so as to maintain the specified pressures
as required by §
65.6.
(f)
Materials and
specifications. Materials and specifications shall include the
following:
(1)
Qualifications. Metallic and nonmetallic materials may be used
separately and in combination to construct component parts of a water system
including, but not limited to, conduits, pipes, couplings, caulking materials,
protective linings and coatings, services, valves, hydrants, pumps, tanks and
reservoirs; provided:
(i) The material shall
have a reasonable useful service life.
(ii) The material shall be capable of
withstanding with ample safety factors the internal and external forces to
which it may be subjected in service.
(iii) The material may not cause the water to
become impure, unwholesome, unpotable or unhealthful.
(iv) Materials and equipment shall be so
selected as to minimize corrosion, electrolysis and deterioration.
(2)
Newly developed
materials and equipment. It is not the intention of this subsection
to prevent the use of newly developed materials and equipment that otherwise
meet the requirements of paragraph (1).
(3)
Minimum requirements for steel
pipeline. The requirements as set forth in paragraphs (1)(i)-(iii)
are intended to be general in nature in order to permit full discretion in the
selection of proper materials and equipment; however, steel pipe used in
transmission and distribution systems shall be lined inside and coated outside
or lined inside and coated and wrapped outside to conform with the applicable
minimum specifications of the American Water Works Association or equivalent
standards, except that those portions laid above ground may be protected on the
outside after cleaning by painting only.
