1. EACH VCW CONTAINS A GROUNDWATER PUMP, AN UPPER ANO LOWER PRESSURE
TRANSDUCER, MANUAL G.4TE VALVES ON THE TREAlMENT INFLUENT AND RETURN WATER LINES,
AND A MOTOR-ACTUATED BALL VALVE ON THE RETURN WATER PIPE. PUMPING AND RETURN
RATES WILL BE CONTROLLED MANUALLY.
2. INITIAL OPERATION WILL BEGIN BY PUMPING EACH WELL AT THE AVERAGE FLOW RATE LISTED
IN THE FINAL DESIGN WORKPLAN. FLOW CONTROL WILL BE ACHIEVED USING GATE VALVES
HV-1 THROUGH HV-7.
3. IF PUMPING RATES EXCEED RECOVERY RATES IN A GIVEN WELL. THE PRESSURE TRANSDUCER
SET IN THE PUMP SECTION WILL SHUT DOWN THE PUMP AND AUTOMATICALLY CLOSE THE
MOTOR-ACTUATED BALL VALVE ON THE RETURN WATER LINE FOR THAT WELL (MAV-1
THROUGH MAV-7), VIA THE PLC.
4. THE VARIABLE FREQUENCY DRIVE (VFD) FOR THE RETURN PUMP SHALL RECEIVE A SPEED
REFERENCE SIGNAL THAT IS PROPORTIONAL TO THE NUMBER Of WELL PUMPS IN OPERATION.
THE VFD SPEED SHALL BE REGULATED IN STEPS BY THE WELL PUMP OPERATION SIGNAL
SUCH THAT THE TOTAL FLOW RATE WILL BE LINEARLY PROPORTIONAL TO THE WELL PUMP
OPERATION USING CENTRIFUG.4L AFFINITY RELATIONSHIPS.
5. FOLLOWING RECOVERY, THE PUMP WILL BE MANUALLY RE-STARTED AFTER THE PUMPING RATE
IS REDUCED ACCORDINGLY. RECOVERY WILL BE DEEMED COMPLETE BASED ON THE SIGNAL
FROM THE LOWER LEVEL PRESSURE TRANSDUCER.
6. WATER RETIJRN (OR RECIRCULATION) RATES WILL BE CONTROLLED USING GATE VALVES HV-9
THROUGH HV-14. A HIGH-PRESSURE SIGNAL FROM THE TRANSDUCER IN THE RETURN
WATER WELL SECTION WILL SHUT DOWN THE GROUNDWATER PUMP AND WILL CLOSE THE
CORRESPONDING MOTOR-ACTUATED VALVE VIA THE PLC. THE PUMPING AND RETURN FLOW
RATES WILL BE MANUALLY REDUCED AND PUMPING WILL RE-START MANUALLY.

7. PUMP OPERATION SIGNALS WILL BE SENT TO THE PLC FOR THE PURPOSE Of REMOTE
MONITORING VIA AUTODIALER.
8. A HIGH SUMP LEVEL IN THE AIR STRIPPER WILL CAUSE AN IMMEDIATE SHUTDOWN OF AU
GROUNDWATER PUMPS. A HIGH OR LOW AIR PRESSURE ALARM IN THE AIR STRIPPER
WILL CAUSE AN IMMEDIATE SHUTDOWN OF ALL PUMPS WHICH PROVIDE FLOW TO THAT AIR
STRIPPER. AT THE SHUTDOWN OF ANY GIVEN GROUNDWATER PUMP, THE
MOTOR-ACTUATED VALVE ON THE RETURN WATER LINE WILL ALSO IMMEDIATELY CLOSE.
9. A HIGH LEVEL ALARM IN THE BUil.DiNG SUMP WILL CAUSE THE SHUTDOWN OF ALL
GROUNDWATER PUMPS AND THE RETURN PUMP, AND THE CLOSING Of ALL
MOTOR-AClUATED VALVES.
10. SIGNALS FROM EACH FLOW METER WILL BE SENT TO THE PLC AT THE CONTROL PANEL
FOR DISPLAY. PRESSURE TRANSDUCER SIGNALS WILL BE SENT TO THE PLC FOR THE
CONTROL OF THE MOTOR-AClUATED VALVES.
11. MOTOR-ACTUATED VALVES MAV-1 THROUGH MAV-7 SHALL BE OF THE lYPE TO FAIL IN
THE CLOSED POSffiON.
12. AN AUTOOtALER WILL BE USED TO NOTIFY OPERATIONS AND MAINTENANCE PERSONNEL OF

GRADE
1. CONTRACTOR TO FURNISH AND INSTALL ALL ELECTRICAi.. EQUIPMENT AS SHOWN ON THE ORAWINGS AND REQUIRED
FOR A COMPLETE, OPERABLE PROCESS. ALL EXTERIOR ENCLOSURES AND RACEWAYS SHAI.L USE TAMPLER-RESISTANT
HARDWARE TO THWART UNAUTHORIZED ACTMTY.
2. INSTALLATION SHALL MEET REQUIREMENTS OF THE NEC, NFPA-70, OR MORE STRINGENT LOCAL CODES, AND HAVE AN
INDEPENDENT INSPECTION TO SO CERTIFY
3. GROUNDtNG SHALL BE A MINIMUM OF (3) 10' LONG X 3/4 • DIA. COPPER-CLAD STEEL EARTH ELECTRODES AT
OCH SERVICE SITE. THE ELECTRODES (RODS) SHALL BE INSTALLED VERTICALLY IN A DELTA CONFIGURATION WITH OCH
A MINIMUM OF 10' APART. THE MAXIMUM RESISTANCE SHALL NOT EXCEED 5.0 OHMS AS MEASURED BY A 3-POINT
TEST. GROUNDING RODS SHALL BE INTERCONNECTED WITH BARE #2 COPPER USING LISTED CONNECTORS. A
PREFERRED ALTERNATIVE FOR THE TREATMENT BUILDING GROUNDtNG IS TO BOND TO THE PAD FOUNDATION REBAR ON
(2) SIDES, PER DRAWING C-2.
4. ALL INTERIOR WIRING SHALL BE A MINIMUM OF lYPE THWN/THHN IN FLEXIBLE METAL TUBING {FMT) FOR EXPOSED
INTERIOR WORK, PROVIDING MECHANICAL MAGNETIC SHIELDING, AND LIQUID-TIGHT CAPA81U1Y. SLEEVES OR CONDUITS
EMBEDDED IN CONCRETE SHALL BE ELECTRICAL METALLIC TUBING {EMT). UNDERGROUND POWER CABLES MAY BE
DtRECT-BURIED, TYPE UF OR EQUIVALENT, EXCEPT THAT ALL INSTRUMENTATION AND CONTROL CABLES MUST INCLUDE A
METALLIC SHIELD FOR EACH PAIR OF WIRES.
5. ALL CONDUCTORS SHALL BE SOUD OR STRANDED COPPER, SIZED TO MEET THE CONNECTED CIRCUIT LOADING PER
NEC REQUIREMENTS. ALL BRANCH CIRCUITS SHALL INCLUDE AN EQUIPMENT GROUNDtNG CONDUCTOR TO ENSURE A LOW f
IMPEDANCE PATH TO EARTH FOR ALL ELECTRICAL EQUIPMENT, PORTABl.£ TOOLS, LIGHTING FIXTURES, AND >
INSlRUMENTATION COMPONENTS. WELL PUMPS AND OTHER MOTOR DRIVES SHALL BE PROVIDED WITH FULL VOLTAGE
NON-REVERSING MAGNETIC STARTERS WITH OVER LOADS ON EACH PHASE. UNDERGROUND MOTOR LEADS TO WELL I
PUMPS SHALL BE #12 COPPER (MINIMUM) TO MINIMIZE STARTING AND RUNNING VOLTAGE DROPS.
