(a)
Maps, drawings, plans and profiles submitted as part of a treatment works
approval application shall conform to the following:
1. Plans shall be drawn to standard scale and
show the entire area of the project, including a general site plan;
2. The name of the New Jersey licensed
professional engineer responsible for the design and his or her signature and
embossed seal shall appear in the title block of each sheet of the submitted
plans;
3. In the event that there
is more than one sheet of plans, all shall be bound together and an index
provided;
4. Plans shall not exceed
30 inches by 42 inches in size;
5.
Streams and wetland areas, if present, shall be clearly indicated;
6. Plans shall show municipal boundaries,
property lines, easements and all existing and proposed streets, including the
existing and proposed surface elevations at all street intersections where
sewer lines are proposed; and
7.
All existing and proposed structures, sanitary sewers and combined sewers, both
above and below ground, shall be shown and clearly labeled.
(b) Symbols used on submitted
drawings shall conform to the following:
1.
Existing and future sewers shall be shown by standard conventions;
2. All topographical symbols and conventions
used shall conform to those of the United States Geological Survey;
and
3. Elevations shown shall meet
the following requirements:
i. Elevations of
the surfaces of streets shall be placed outside the street lines, opposite
their respective locations;
ii.
Elevations of sewer inverts shall be shown at intersections, ends of lines, and
wherever a change in sewer grade occurs;
iii. The elevation of sewers shall be written
close to the point to which they refer, parallel with the sewer lines and
between the street lines;
iv. The
elevations of surfaces shall be drawn to the nearest 0.1 foot and those of the
sewer inverts to the nearest 0.01 foot; and
v. All elevations shall be referenced to the
North American Vertical Datum of 1988.
(c) The horizontal distances and stationing
between manholes, grades in percent and sewer sizes and materials shall be
shown for all proposed sewer lines.
(d) All sewer appurtenances, such as
manholes, siphons and pumping stations shall be designated on the plans by
appropriate symbols and referenced by a legend.
(e) Plans labeled preliminary are not
acceptable for review unless a note is added to each sheet submitted stating
that the plans are final with respect to sanitary sewer design.
(f) Plans submitted for treatment works that
are already constructed shall show the "as-built" conditions (as determined
through field investigation) and the title block of each sheet shall include
the term "as-built."
(g) Profiles
and construction details shall meet the following requirements:
1. Profiles shall indicate all manholes,
pumping stations, sanitary, combined or industrial sewer lines, concrete
encasements, sleeves, and any significant crossings such as storm sewers,
potable water lines or utility lines.
2. In the case of stream crossings,
elevations of stream beds, normal flow lines and the type of sewer pipe with
the length of concrete encasement, as required by
N.J.A.C.
7:14A-23.6(b), shall be
indicated.
3. The size and
gradients of sewers, surface elevations and sewer inverts shall be shown at or
between each manhole.
4. Profiles
of gravity and forced sewer lines shall be drawn to standard scale with all
symbols indicated in the legend.
5.
Detail drawings of all sewer appurtenances, such as manholes, drop manholes,
inspection chambers, siphons, pumping stations, force main connections into
manholes and other related items shall accompany the general sewer system
plans.
6. For sewage treatment
plants, in addition to all other requirements, the plans shall contain the
following:
i. A general plan showing site
boundaries including areas reserved for future expansions;
ii. All buildings or building lots within 500
feet of the plant property;
iii. A
detail plan of the various units and structures which comprise the plant;
and
iv. Detail plans showing a flow
diagram, and longitudinal and transverse sections sufficient to explain the
construction of each unit including hydraulic gradient.
(h) Specifications for the
construction of treatment works shall be directly applicable to the engineering
(including hydraulic) features of the proposed project and shall meet the
following minimum requirements:
1. Detailed
information shall be included on the construction methods and materials
proposed for use so as to provide the construction contractor with the specific
details necessary to satisfy the project design; and
2. Specifications shall address the
following:
i. The quality of materials and
workmanship;
ii. The operating
characteristics and equipment rating;
iii. Allowable infiltration/exfiltration and
the testing procedures to be followed;
iv. Requirements for all mechanical and
electrical equipment necessary for the treatment works; and
v. A program for maintaining the operation of
existing sewerage systems during construction.
