Summary

This is a preliminary design document for a Master Meter and Booster Pump Addition project at Wayne Community College in Wayne County, North Carolina, prepared by Timmons Group engineering firm. The project involves the installation of water infrastructure to serve the entire WCC campus, designed to handle an average daily flow of approximately 120 GPM with a maximum daily demand of 300 GPM and required fire flows of 1,500 GPM per hydrant. The system includes three Cornell Model 2YH low-service booster pumps capable of 150 GPM at 65 feet of lift, two Cornell Model 5RB high-service booster pumps capable of 1,500 GPM at 116 feet of lift, one 8-inch turbine master meter, one 8-inch RPZA (Reduced Pressure Zone Assembly), 275 linear feet of 10-inch DIP water main, nine 10-inch isolation valves, one 10-inch check valve with vault, and a pump building structure. The design includes provisions for a bypass vault approximately 24 linear feet in front of the booster pump house to maintain water flow during maintenance operations.

The project documentation consists of site plans, erosion and sediment control plans, mechanical plans with sections and isometric views, and detailed specifications for the booster pump station components, including the meter vault, check valve vault, reduced pressure zone assembly, concrete foundation pads, and generator concrete pad. All piping is specified as ductile iron with mechanical joints for buried applications and flanged Class 53 for above-grade or exposed pipe. The design incorporates a low-pressure cutoff on all booster pumps to prevent vacuum conditions, restrained joint piping throughout, and electrical infrastructure including a 300-ampere breaker in an existing switchboard with 4/0 copper conductors to the pump house. Construction sequencing requires installation of primary erosion and sedimentation control measures prior to land-disturbing activities, with stabilization of graded slopes required within 21 calendar days and permanent seeding using Bermudagrass or fall/winter rye grass depending on season.

2. A LOW-PRESSURE CUTOFF SHALL BE INSTALLED ON ALL BOOSTER PUMPS TO PREVENT THE CREATION OF A VACUUM OR NEGATIVE PRESSURE ON THE SUCTION SIDE OF THE PUMP WHEN

THE SUCTION PRESSURE IS 10 PSI OR LESS. THIS IS IN ACCORDANCE WITH NCPC 606.5.5.

3. ALL PIPING SHALL BE RESTRAINED JOINT.

4. ALL BURIED PIPE SHALL BE DUCTILE IRON MECHANICAL JOINT CLASS 52 AND ALL ABOVE GRADE OR EXPOSED PIPE SHALL BE DUCTILE IRON FLANGED CLASS 53 UNLESS OTHERWISE NOTED.

5. ALL WIRING SHALL BE COPPER THHN-2 OR THWN-2.

KEY NOTES:

1. PROVIDE (4) #350KCM, (1) #4 GND, IN 4" SCHEDULE 80 PVC CONDUIT FROM SWITCHBOARD "MDS" TO DISCONNECT AT PUMP HOUSE. MINIMUM BURY DEPTH SHALL BE 24". PROVIDE RGS ELBOWS FOR TRANSITION FROM BELOW TO ABOVE GRADE. PROVIDE RGS CONDUIT FOR ALL ABOVE GROUND PORTIONS OF THE FEEDER.

2. PROVIDE 300A/3P 65KAIC BREAKER IN EXISTING SQUARE D QED-2 SWITCHBOARD TO SERVE PUMP HOUSE.

3. PROVIDE (1) 400A, SE RATED, 65AIC, NEMA 3R, 600V, 3-PHASE, FUSED DISCONNECT WITH 300A FUSES TO SERVE AS THE DISCONNECTING MEANS FOR THE PUMP HOUSE. PROVIDE 3/4" X 10 FT GROUND RODS IN TRIAD PATTERN ADJACENT TO PUMP HOUSE AND CONNECT TO GROUND BUS OF DISCONNECT. UTILIZE #3/0 BARE COPPER GND FOR ALL GROUNDING WITHIN THE TRIAD AND TO DISCONNECT. INSTALL GROUNDING WIRE IN SCHEDULE 80 PVC CONDUIT WHEN ABOVE GROUND. PROVIDE CONNECTION FROM DISCONNECT TO PUMP HOUSE PANEL USING (4) #350KCM, (1) #4 GND, IN 4" RGS CONDUIT. NEUTRAL AND GROUND BUS SHALL REMAIN INDEPENDENT FOR THE PUMP HOUSE.

SEQUENCE OF CONSTRUCTION

1. THE CONTRACTOR SHALL CONSTRUCT AND PLACE INTO OPERATION ALL PRIMARY EROSION AND SEDIMENTATION CONTROL PRACTICES FOR THE SITE (SILT FENCE, SEDIMENT BASINS AN TRAPS, AND WATER CONVEYANCE MEASURES)

PRIOR TO UNDERTAKING MAJOR LAND-DISTURBING ACTIVITIES.

2. STABILIZE ALL CONSTRUCTION ACCESS ROUTES, CONSTRUCTION ENTRANCES/EXISTS, AND ASSOCIATED DRAINAGE

SYSTEM. INSTALL INLET PROTECTION DEVICES.

3. INSTALL DIVERSIONS ABOVE AREAS TO BE DISTURBED AND LOCATE DIVERSION DIKES ALONG GRADING BOUNDARIES

PRIOR TO GRADING ACTIVITIES.

4. PERFORM LAND CLEARING, ROUGH GRADING, AND PIPELINE INSTALLATION. CLEAR AREAS ONLY NEEDED.

5. BACKFILL PIPELINE AND COMPLETE FINAL GRADING AND SURFACE STABILIZATION TO MINIMIZE THE TIME OF EXPOSURE AND SELECT TEMPORARY GROUND COVER ACCORDING TO LOCATION AND SEASON. TEMPORARY SURFACES SHOULD BE STABILIZED AS SOON AS ACTIVE GRADING IS SUSPENDED OR BACKFILL IS COMPLETE. GRADED SLOPES AND FILLS MUST

BE STABILIZED WITHIN 21 CALENDAR DAYS, REGARDLESS OF TIME OF YEAR.

6. INSPECT EROSION CONTROL MEASURES WEEKLY AND AFTER EACH RUNOFF-PRODUCING RAINFALL. FREQUENTLY INSPECT PROPERTY BOUNDARY FOR EVIDENCE OF SEDIMENTATION. MAINTAIN EROSION CONTROL MEASURES AS NECESSARY AND ADDRESS ANY SEDIMENTATION AT EROSION CONTROL MEASURES, PROPERTY BOUNDARY, OR OFF-SITE SEDIMENTATION DUE TO UNDER-PERFORMING SEDIMENT CONTROL MEASURES UNTIL FINAL APPROVAL IS RECEIVED AND

ALL AREAS ARE STABILIZED..

7. REMOVE TEMPORARY EROSION CONTROL MEASURES.

SEEDING AND MULCHING (EAST):

THE KINDS OF SEED AND FERTILIZER, AND THE RATES OF APPLICATION OF SEED, FERTILIZER, AND LIMESTONE, SHALL BE AS STATED BELOW. DURING PERIODS OF OVERLAPPING DATES, THE KIND OF SEED TO BE USED SHALL BE DETERMINED. ALL

RATES

ARE IN POUNDS PER ACRE.
