Section 6 The Selected Alternative Plan
EAA Storage Reservoirs Revised Draft PIR and EIS February 2006
6-24
Medium-sized pumping stations will be configured similar to that shown on
Plates M-1 through M-6. Plates M-1 through M-3 show the plan and sections for
four-bay pumping station S-611. Plates M-4 through M-6 show the other
medium-sized pumping station, S-610, which is a nine-bay station. The pumps
at both medium-sized pumping stations are expected to run at less than 500 rpm
with an efficiency of about 80%. The diesel engine pump drives should be in a
range of from 1330 to 1630 horsepower each. The electric motor pump drives
should be 400 or 500 horsepower each.
Each of the medium-sized pumping stations will include various support items
including the following:
1. Diesel fuel system, including vaulted double-wall aboveground fuel
storage tanks capable of holding enough fuel to operate all of the engine
driven pumps and the emergency generator continuously for 7 days. Day
tanks shall be provided and sized to adequately supply the diesel engine
pump drives and generator within the limitations of NFPA 37. The FAC
shall be followed in designing the fuel system for the pumping station.
2. An overhead bridge- type electric crane/hoist will typically be used. The
crane/hoist shall be capable of lifting and moving loads up to the heaviest
loads in the pumping station. The crane/hoist will handle pumping
station equipment such as the diesel engine pump drives, reduction gears,
and the pumps during initial installation as well as for general service
thereafter.
3. Potable water system and a septic system for the plumbing fixtures.
4. Plumbing facilities to include a toilet with a water closet, a lavatory, and a
kitchen-type sink.
5. Ventilation system to provide fresh air in the pump bays, generator area,
and toilet room.
6. Air-conditioning system for the office.
7. Stilling wells containing float switches to be used for pump operations and
water level monitoring.
8. Trash rake/rack system will be an automatic, continuously rolling, flex
rake and trash rack system such as that manufactured by Duperon.
9. An emergency generator to supply power to the electrical equipment at
the stations in the event of commercial power outage. This will include
