PUMP ISOMETRIC & DETAILS

1. THE LOCATION AND ELEVATION OF EXISTING STRUCTURES, PIPING, AND UTILITIES SHOWN ARE BASED ON THE WATER TREATMENT PLANT 1997 RECORD DRAWINGS. THE CONTRACTOR SHALL VERIFY ALL DATA IN THE FIELD PRIOR TO CONSTRUCTION. THE DIAMETERS OF EXISTING PIPING ARE APPROXIMATE AND SHALL BE VERIFIED PRIOR TO PERFORMING FINAL CONNECTIONS.

2. CHANGES IN NEW PIPING FROM THAT SHOWN ON THE DRAWINGS, IN ORDER TO AVOID CONFLICTS WITH EXISTING ELECTRICAL SYSTEMS, MECHANICAL SYSTEMS, EQUIPMENT, STRUCTURES, OR EXISTING PIPING, SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR WHETHER THE CONFLICTS ARE SHOWN OR ARE DISCOVERED IN THE FIELD. LIKEWISE, ALTERATIONS TO EXISTING ELECTRICAL SYSTEMS, MECHANICAL SYSTEMS, EQUIPMENT, OR EXISTING PIPING IN ORDER TO ACCOMMODATE NEW PIPING AND EQUIPMENT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR AT NO ADDITIONAL COST TO THE OWNER. THE OWNER AND THE ENGINEER MUST APPROVE ALL SUCH CHANGES.

3. PROVIDE A MINIMUM OF 6 INCHES CLEARANCE BETWEEN PIPING AND FOOTINGS, STRUCTURES, AND OTHER PIPING UNLESS OTHERWISE INDICATED.

4. VERTICAL PIPE FITTINGS ARE NOT SHOWN ON THE DRAWINGS FOR CLARITY. THE CONTRACTOR SHALL PROVIDE VERTICAL PIPE FITTINGS AS REQUIRED FOR COMPLETE AND OPERABLE PIPE INSTALLATIONS. PROVIDE ALL CONNECTING PIECES AND TRANSITION PIECES REQUIRED TO MAKE FINAL PIPING CONNECTIONS.

5. THE CONTRACTOR SHALL COMPLY WITH ALL FEDERAL, STATE, AND LOCAL CONFINED SPACE ENTRY REGULATIONS.

6. MAINTAIN ALL OVERHEAD AND UNDERGROUND ELECTRICAL, TELEPHONE, WATER, AND GAS SERVICES AND ALL OTHER PERIOD. PHASES OF CONSTRUCTION INVOLVING TEMPORARY INTERRUPTION UTILITIES DURING ENTIRE CONSTRUCTION PERIOD. THE CONTRACTOR SHALL MAINTAIN WATER SERVICES TO THE MAXIMUM EXTENT POSSIBLE DURING THE CONSTRUCTION OF ESSENTIAL SERVICES AND DEMOLITION OF EXISTING EQUIPMENT SHALL BE SCHEDULED IN CONSULTATION WITH THE OWNER, SHALL NOT BE LONGER DURANTION THAN ESSENTIAL TO ACCOMPLISH THE PURPOSE FOR SUCH INTERRUPTIONS, AND SHALL BE COORDINATED TO GIVE THE OWNER THE ABILITY TO MAINTAIN WATER PRODUCTION.

7. THE CONTRACTOR SHALL COORDINATE ELECTRICAL POWER SUPPLY WITH THE OWNER PRIOR TO CONSTRUCTION. ALL ELECTRICAL POWER AND CONTROL WIRING, CONDUIT, AND ELECTRICAL APPURTENANCES REQUIRED SHALL BE SIZED, PROVIDED, AND INSTALLED BY THE CONTRACTOR IN ACCORDANCE WITH THE LATEST EDITION OF THE NATIONAL ELECTRICAL CODE AND POWER COMPANY STANDARDS. POWER AND CONTROL WIRING SHALL BE INSTALLED IN SEPARATE CONDUITS.

8. ALL TUBING, PIPING, PUMPS, EQUIPMENT, AND OTHER APPURTENANCES ASSOCIATED WITH THIS PROJECT MUST COMPLY WITH NSF STARD 61 TO ENSURE IT IS SATISFACTORY FOR USE WITH POTABLE WATER APPLICATIONS.

9. THE TOWN OF AMHERST WATER TREATMENT PLANT OPERATORS SHALL MAINTAIN AND UTILIZE THE SPECIFIC ION ELECTRODE METER CURRENTLY USED IN THE LAB FOR REPORTING THE FINISHED WATER FLUORIDE CONCENTRATION IN THE MONTHLY REPORTS AS WELL AS FOR COLLECTION OF SPLIT FLUORIDE SAMPLES.
