Polyurethane baked enamel!
Accurate measurement of the liquid level in the wetwell shall be made by the
bubbler type system in which variations of liquid level shall produce
corresponding variations in the air pressure required to maintain bubbling and
this pressure shall be applied to a solid state strain gauge type pressure
transducer mounted within the digital controller. The bubbler control system

over the entire range. The bubbler system shall contain its own duplex air
compressor assembly, pressure reducing valve, air flow regulator and automatic
high pressure purge cleaning of the bubbler.
There shall be flush mounted on the face of the door of the pump control panel
a solid state digital pump controller, Control Manufacturing Co. Model
VariMAC Model 3300 or equal. The controller shall be a microprocessor based
front of panel programmable controller to automatically and alternately
sequence the pumps per the following operating schedule. The controller shall
have independently field adjustable front of panel programming setpoints for
each of the pumps and 3 independent 4— 20 ma variable speed signals. The
controller shall also have independent high and low level alarm setpoints,

which will display the controller signal. Each pump shall be automatically
alternately sequenced or manually selected into the lead, lag, lag —lag or
standby pump programming positions. The standby pump shall be automatically
inserted into the program on a selected pump failure condition.
As the demand for pumping capacity increases, the lead selected variable speed
pump shall automatically start at its specific minimum speed and be increased
in speed to precisely match system demand. If the demand exceeds the capacity
of the first pump running at maximum speed, the lag pump shall be
automatically programmed at its setpoint and start at its setpoint minimum
speed. The lag pump shall then increase in speed to match the system
requirements. The transfer shall be smooth, bumpless and an overlap dead band
to prevent hunting.
The selected standby pump shall be programmed similar to above to match the
system demand.
On decreasing system demand for pumping capacity, the pumps shall automatically
reduce speed to match demand until dropping to minimum speed setpoint. If the
demand continues to decreae, the pumps shall be automatically stopped. This
flying transfer shall be frequency synchronized to eliminate any electrical
transients or adverse motor current inrush conditions. Under a minimum system
demand condition the lead pump speed shall be reduced to its setpoint minimum
speed and held until the signal falls to the setpoint "stop" level. The
processor control logic shall automatically provide for power failure
recycling of each variable speed pump in the event of a power outage so as to
minimize inrush current and loading on the electrical circuit.

PART 3 — CONSTRUCTION METHODS —
SP — 300-1 EARTHWORK
301-1.1 General — Work shall consist of performing all operations necessary to
excavate earth and rock, regardless of character and subsurface conditions at
the pump station site, and at pipeline trenches, including backfill,
compaction where required by the Plans or directed by the Soil Engineer;
including removal of obstructions, placement of select fill material,
conditioning of material to proper moisture content for compaction, removal,
replacement and disposal of unsuitable material, preparation of foundation and
base materials for placing other material thereon, all as shown on the Plans,
as specified herein and as directed by the Engineer.
Earthwork and subgrade preparation shall conform with Standard Specifications,
Section 300 except as modified herein.
Whenever reference is made to finished grade, it shall be considered to be
finished surface of the completed facility.
In connection with earthwork, tests shall be made in conformance with the
following:
Relative Compaction: Test method No. Calif. 216
Sand Equivalent: Calif Test No. 217
Resistance (R —value): Calif. Test No. 301

300 — 1.3 — DISPOSAL OF EXCESS MATERIAL. Excess excavated material shall be
disposed outside of the City of San Mateo or as directed by the Engineer.
Excavated material suitablle for backfill shall be stored temporarily in such a
manner as will facilitate work under the contract. The Contractor shall make
all necessary arrangements with respective Property Owner for temporary
storage of excavated material to be used.
300 — 3.7 CONTROL OF WATER. Contractor shall furnish, install and operate all
necessary machinery, appliances and equipment to keep excavations and trenches
reasonably free from water during construction and shall dispose of the water
so as not to cause injury to public or private property, or to cause a
nuisance or menace to the public. He shall at all times have on hand
sufficient pumping equipment and machinery in good working condition for all
ordinary emergencies and shall have available at all times competent mechanics
for the operation of all pumping equipment. During pouring of concrete, and
until concrete has set hard, and during the laying of pipe, excavations shall
be kept free of water.

300 — 3.9 REMOVAL OF OBSTRUCTIONS. Contractor shall remove or caused to be
removed at his expense, all trees, bushes, fences and all structures as and
when required by the plan , or where the proper construction and completion of
the work require their reoval. Contractor shall also remove at his expense,
all rock, stones, debris and all obstructions of whatsoever kind of character,
whether natural or artificial, encountered in the construction of the work.
Material that is removed as hereinabove specified and is not to be
incorporated into the improvement being constructed shall be disposed of off
site by contractor at his own expense.
300 — 3.10 CONTROL OF OUST. Contractor shall keep roads clear of material or
watered so that traffic or construction operations will not cause an

imported material. Backfill should be free of debris, organics and rocks
greater than six inches in diameter. In addition, the fill material
should have a low expansion potential (liquid limit less than 25 and
plasticity index less than 15). Selection of suitable material for use as
structural backfill will be under the control of the Engineer. In
general, with the exception of expansive surface soils, material from the
excavation can be used for backfill,
c. Area under pump station foundation shall be filled to a depth of 12 inches
with Class II 1 1/2" maximum aggregate base and compacted to 95% relative
compaction. All other areas shall be compacted to 90% as determined by
ASTM 01557-70(C).
d. Backfill shall not be placed until all forms, rubbish and deleterious
materials have been removed and the areas receiving backfill have been

compaction. Material that does not contain sufficient moisture to compact
properly shall be sprinkled with water. Material that is too wet shall be
permitted to dry to the proper water content. Material and water shall be
thoroughly mixed before compaction.
f. Compacting shall be accomplished by power tamping, rollers, or
combinations thereof. Where it is impractical to use rollers in close
proximity to walls, etc., fill material shall be compacted by mechanical
tamping.
