SECTION 13

SEWAGE PUMPING STATION
(Submerged Pump Type)

13.01
SCOPE:

These Specifications form a part of the Contract
Documents and shall govern for the construction of
sewage pumping stations. The Work covered by this
Section includes the furnishing of all parts, labor,
equipment, appliances and materials, and performing
all operations in connection with the construction and
installation of sewage pumping stations complete
with pumps, piping, wet well, controls, electrical
work and all necessary auxiliary equipment. The
station shall be complete and in strict accordance
with this Section of Specifications and the applicable
Plans and subject to the terms and conditions of the
Contract. See Appendix D and E for Standard
Details pertaining to this Section.

Where variable speed pumping is specified, all
additional considerations relative thereto shall be
provided including but not limited to pumps,
controls, buildings, shelters, and accessories.
Contract Drawings included in Appendix D and E are
intended to reflect single speed pumping and shall be
considered only as a general guide where variable
pumping is specified.

13.02
MATERIALS:

Materials of this Section shall be as specified herein.

13.03
INTENT OF PLANS AND
SPECIFICATIONS:

The intent of the Plans and Specifications associated
with this Section is to provide a completed sewage
pumping station which will function as intended and
is ready for operation.

It shall be the responsibility of the Contractor as a
part of this Work through careful quality control and
coordination with the Engineer to avoid all conflicts
occurring during construction such as available
space, routings, mis -matched or otherwise
incompatible component selection, incomplete
systems, substitutions, etc.

Where inter-system components, devices, adaptors,
etc., are not specified or noted in the design, but
required to complete the system, it shall be the
responsibility of the Contractor to provide such items
and material as a part of this work.

Unless otherwise noted, items specified herein by
manufacturer or trade name shall be used as a guide
to quality and inherent features and such reference
shall not be intended to restrict the Project to such
listing.

The Plans and Specifications included herein and
Appendix D and E reflect single speed pumping.
Where variable speed pumping is specified, all
additional requirements associated therewith shall be
met by the Contractor. Special Drawings and
Specifications shall be submitted by the Contractor
for the Engineers evaluation covering all equipment,
controls, material, and construction procedures for
variable speed pumping.

The actual field installation shall reflect only that
material and equipment submitted and approved by
the Engineer. Any work performed without an
approved submittal and considered not acceptable by
the Engineer shall be removed and reworked at the
Contractors expense.

13.04
SUBMITTALS AND TESTS:

A.
Submittals:

Prior to installation of any material or
equipment, the Contractor shall submit for
approval of the Engineer, five sets of
required submittal material indicating item
identification, manufacturer, type, size,
ratings, and other descriptive information
required for adequate evaluation. Wiring
diagrams shall be submitted where item
function description necessitates, and as
required by the Engineer. Submittals shall
be conspicuously marked to denote
departures from the design references shown
on Plans or specified. Incomplete or
otherwise indiscernible submittals will not
be evaluated.

Submittals shall bear a stamp or specific
written indication that the Contractor has
satisfied his responsibilities under the
13 - 2
10/98

Contract with respect to the Contractors
review of the submission.

Omissions and/or design revisions made in
submittals shall not relieve the Contractor
from the responsibility of providing the
omitted item or required material as a part of
this Work. Approval by the Engineer shall
not constitute acceptance of an erroneous or
incomplete system submittal.

The Contractor, at his option, may submit
for evaluation two copies of submittal
material, one of which will be marked and
returned. The required number of copies,
corrected as marked, will then be submitted
for approval stamping to the Engineer.

1.
Material submittals shall be
manufacturers catalog sheets or
similarly published data marked to
denote only the item or items
covered by the submittal. Materials
of unique production shall have
special submittal attention to give
complete identification of the
materials being proposed.

2.
Equipment submittals shall present
the equipment for evaluation as a
unit piece including all component
parts by manufacturers
designation. Submittals shall be
marked to denote only the
equipment being proposed and
shall be complete including
electrical, physical, and operational
data. Additional supporting data
shall be provided where necessary.

3.
Fabrications, assemblies, and
special productions shall have
submittals of unique preparation to
present the finished item
completely identified. Such Shop
Drawings shall include all material,
components, and assembly work.

4.
Systems composed of multiple
component parts or subsystems
shall have submittals to denote the
system as a completed composite.
All component parts and
subsystems shall be identified.

5.
Documentation of the finished
installation shall be made as a part
of final acceptance and shall
include corrected submittals,
operation and maintenance
publications, and other data
necessary to accurately define the
final field installation.

B.
Tests, Instructions and Reports:

The following listed items shall be required
in addition to other special requirements
within these Specifications.

1.
Written conductor insulation
resistance test.

2.
Written ground rod resistance test.

3.
Local public electrical inspectors
certificate.

4.
Operational demonstration test.

13.05
CLEARING:

In general, clearing shall consist of the removal and
disposal of all undergrowth, brush, logs, trash and
other objectionable obstructions. All materials
cleared from the site shall be disposed of off the site
by the Contractor. It is the intent that the entire area
within the limits of the sewage pumping stations as
shown on the Plans shall be cleared.

13.06
EXCAVATION FOR PIPES AND
STRUCTURES:

A.
General:


The Contractor shall perform excavation of
every description regardless of the nature of
the materials encountered. Trenches or
foundations for pipes or structures shall be
excavated to the lines, grades, and elevations
shown on the Plans. Trench and structure
excavations shall be of sufficient size to
permit the placing of pipes and forms.

B.
Overcuts:


If at any point in excavating for structures
material is excavated beyond the neat lines
upon or against which concrete is to be
placed, the overcut shall be filled with reef
shell, crushed slag or crushed stone fill
13 - 3

properly compacted, or with concrete, as
directed by the Engineer. The proposed
elevations and positions for the different
structures are shown on the Plans; however,
the Engineer reserves the right to make such
modifications as in his opinion are necessary
to carry out the intent of the Plans or
Specifications. No payment will be made
for overcuts or reef shell, crushed slag or
crushed stone fill in overcuts. Reef shell,
crushed slag or crushed stone shall be as
specified in Section 16 entitled Erosion
Control.

C.
Dewatering:


Should lowering of ground water be
necessary for the installation of concrete
structures, piping, etc., or to prevent lateral
movement of material under concrete
already placed, such lowering shall be
accomplished in accordance with Section 10
entitled Special Provisions, paragraph
entitled Dewatering, at no additional cost
to the Owner.

13.07
CONCRETE:

The minimum compressive strength required at 28
days is 3000 pounds per square inch. Field

The foundation of the wet-well shall consist of a
reinforced concrete slab poured on undisturbed earth
in accordance with details shown on the Plans. See
Appendix D.

The barrel of the wet-well shall be constructed of
sections of reinforced concrete pipe conforming to
ASTM 3 Specification Designation C76, Class II.
Concrete for pipe shall be Type II Portland Cement
with 100 percent calcareous aggregate.

The diameter, height, opening and other details shall
