NOTES
<br />All miscellaneous metal parts in the wet well shall be fabricated from stain
<br />steel.
<br />N'
<br />The electrical control panel shall have a programmable process control panel,
<br />radio telemetry provisions, a motor control center suitable for the pump motors,
<br />AM
<br />a transfer switch, a run time meter for each pump, a run light for each pump,
<br />a "Hand -Off -Auto" switch for each pump, a 120 volt convenience outlet with
<br />1, 500 watt capacity and two receptacles, and a switch to control the overhead
<br />light.
<br />3. The programmable process control panel shall match the existing control panels
<br />used by the City of Tracy at similar lift stations and shall be a "Liquitronic IV"
<br />as manufactured by Tesco. No substitutions will be allowed. The
<br />programmable process control panel shall be programmed to match the control
<br />method and alarm indications of similar duplex lift stations installations in the
<br />City of Tracy.
<br />4. The programmable process control panel shall be programmed to turn on the
<br />lead pump at an elevation of 90.7', turn on the lag pump at a water elevation
<br />of 91.2', actuate an alarm at a water elevation of 91.7', and turn off any
<br />pumps running at a water elevation of 86.0'. The lead pump shall be
<br />alternated each time the pump off elevation is reached.
<br />5. Alarm indications shall be as follows:
<br />o High water level.
<br />o Low or high voltage or phase disturbance.
<br />o North pump overheat.
<br />o South pump overheat.
<br />o North pump seal leakage.
<br />o South pump seal leakage.
<br />o Generator alarms (detailed in electrical specifications).
<br />Each indication shall cause the radio telemetry equipment to send an alarm and
<br />shall cause a corresponding labeled light to turn on in the control panel. The
<br />light shall remain on until it is manually reset. Activation of an alarm shall not
<br />• change the control logic.
<br />6. The radio telemetry equipment shall match the existing radio telemetry
<br />equipment used by the City of Tracy at similar lift stations and shall be as
<br />manufactured by Tesco. No substitutions will be allowed.
<br />7. The transfer switch shall be an automatic switch to turn on the emergency
<br />generator in the event of a power failure. The switch shall meet all applicable
<br />PG&E standards and shall prevent any possibility of a simultaneous connection
<br />of the generator and the power grid.
<br />8. The electrical equipment shall be housed in a NEMA 4X enclosure or enclosures
<br />1
<br />1 fabricated from cold rolled steel with padlocking closures and a padlock keyed
<br />to the City Standard.
<br />9. The conduits for the power cables leading from the control panel to the pumps
<br />shall be 2" diameter schedule 40 rigid conduit. The bubbler conduit shall be
<br />1/2" diameter schedule 40 rigid conduit. Conduit from the electrical control
<br />panel to the wet well shall be threaded galvanized steel or threaded galvanized
<br />iron. The bubbler conduit inside the wet well shall be glued socket PVC. On
<br />the horizontal run, the conduits shall have 18" of cover. Conduits shall be
<br />tightly sealed around the cables at both ends with non -hardening sealant.
<br />Power cables shall be provided with a cord grip at the wet well end of the
<br />conduit. There shall be no splices in any of the cables or air lines running
<br />-inside the conduits between the electrical control panel and the associated
<br />device.
<br />10. The level sensor shall be a reactive air level monitoring system as manufactured
<br />by Tesco. The transmitter shall be mounted to the wet well wall in accordance
<br />with the manufacturer's recommendations in an indentation in the grout fillet,
<br />which will be formed to provide a 6 inch minimum clearance around the
<br />' transmitter.
<br />1. The pumps shall be non -clog submersible pumps designed for use with a guide
<br />rail system. No entry of the wet well shall be necessary to connect the pumps
<br />or remove the pumps for maintenance. Each pump shall deliver at least 250
<br />gpm at a total dynamic head of 48 feet and shall not deliver more than 310
<br />" gpm at a total dynamic head of 48 feet. Each pump shall be capable of at least
<br />10 starts per hour on a continuing basis without damage and shall be capable
<br />of passing a 3" sphere. The pump efficiency at a 250 gpm flow rate shall be
<br />at least 50%. The pumps shall use 7.5 horsepower motors wired for 1750
<br />rpm operation with 230 volt 3 phase power and shall be non -overloading over
<br />the entire pumping range. The pumps shall have high temperature sensors with
<br />n associated automatic shut-off and shall have a seal failure sensor. Th
<br />ps shall be S4MX pumps with 7.88' impeller and the "Dual Rail
<br />Iffigactured by Aurora/Hydromatic
<br />r]
<br />,%
<br />r
<br />2. Ductile iron pipes and fittings shall meet the applicable portions of the latest
<br />revisions of the AWWA C110, C111, C115, C151 and C153 standards. The
<br />ductile iron pipe and fittings shall be cement mortar lined in accordance with
<br />the latest revision of AWWA C104. Buried ductile iron piping shall have a
<br />bituminous external coating at least 1 mil thick. Ductile iron pipe which is not
<br />buried shall be painted brown with a high solids epoxy.
<br />13. All mechanical joint fittings shall have locking wedge retaining glands. Locking
<br />wedge retaining glands shall be Megalug as manufactured by EBAA Iron Sales,
<br />Inc. or approved equal.
<br />14. Where a pipe or conduit penetrates a manhole ring, a clean hole large enough
<br />to allow grout to be tightly packed around the pipe for the full thickness of the
<br />manhole wall shall be cut. Where a pipe penetrates the valve vault a clean hole
<br />large enough to allow grout to be tightly packed around the pipe for the full
<br />thickness of the valve vault wall shall be cast in or a knockout provided. The
<br />clearance between the wall and the pipe shall not exceed 2". A sand cement
<br />grout shall be used to seal the space between the pipes and the precast wall
<br />and shall be tightly packed for the full thickness of the wall.
<br />15. Submittals shall be provided for the precast valve vault, the valve vault cover,
<br />the wet well cover, electrical control panel and all associated equipment called
<br />out in note 3., the electrical conduit, the bubbler, the overhead light, the
<br />pumps, the piping and fittings, the check valves and the gate valves. The
<br />submittals shall contain enough information to show that the proposed
<br />equipment is exactly the make and model specified or is the equal in every
<br />respect of the make and model specified, or, where no make and model has
<br />been specified, that the proposed equipment meets the requirements listed and
<br />is suitable for the intended use. The Contractor shall submit 5 copies of each
<br />submittal to the Engineer. The Engineer shall evaluate the submittals and mark
<br />them with the stamp shown below. Within 5 working days of the receipt of
<br />a given submittal, the Engineer will send 1 copy to the Owner, send 1 copy to
<br />the City of Tracy, and send the remaining two to the'Contractor. Until the
<br />Contractor has received a submittal marked with either "No Exceptions Taken"
<br />or "Make Correction Noted" the Contractor shall not proceed with any portion
<br />of the work which would be adversely affected by the rejection of the
<br />submittal.
