7. UNLESS CALLED FOR OTHERWISE IN THESE PLANS, ALL SEWER SERVICE LATERALS SHALL BE CONNECTED TO THE SEWER MAIN BY INSTALLING 45 DEGREE WYE FITTINGS. SEWER TAPS AND SADDLES WILL REQUIRE WRITTEN APPROVAL FROM THE SEWER UTILITY PRIOR TO USE. FOR DEEP SEWER MAINS, THE WYE AND 1/8 BEND SHALL BE ROTATED TOWARD THE VERTICAL POSITION AS NEEDED IN ORDER TO OBTAIN 5 FEET TO 6 FEET OF COVER FROM FINISH GRADE AT THE RIGHT-OF- WAY OR AT THE TERMINUS END OF THE SERVICE LATERAL. 

8. UNLESS CALLED FOR OTHERWISE IN THESE PLANS, ALL SEWER SERVICE LATERALS ARE TO HAVE 5 FEET TO 6 FEET OF COVER FROM FINISH GRADE AT THE RIGHT-OF-WAY LINE OR AT THE TERMINUS END OF THE SERVICE LATERAL. LOTS WITHOUT UTILITY EASEMENTS ADJACENT TO THE STREET RIGHT-OF-WAY SHALL HAVE THEIR SERVICE LATERALS TERMINATE JUST OUTSIDE OF THE RIGHT-OF-WAY. LOTS WITH UTILITY EASEMENTS ADJACENT TO THE STREET RIGHT-OF-WAY SHALL HAVE THEIR SERVICE LATERALS EXTENDED THROUGH THE UTILITY EASEMENT BEFORE TERMINATION.THE CONTRACTOR IS TO PLUG AND PROVIDE A LOCATOR WIRE AND STAKE AT THE TERMINUS END OF EACH SERVICE LATERAL. THE CONTRACTOR IS TO TIE/MEASURE (AND MAINTAIN RECORDS OF THE TIES/ MEASUREMENTS) THE TERMINUS END LOCATION OF EACH SERVICE LATERAL TO TWO OR MORE PROPERTY CORNERS. FAILURE OF THE CONTRACTOR TO MAINTAIN RECORDS OF SERVICE LATERALS’ TERMINUS END LOCATIONS MAY BE CAUSE TO HAVE THE CONTRACTOR TO FIELD EXPOSE SERVICE LATERALS’ TERMINUS END LOCATIONS AT NO ADDITIONAL COST TO THE CONTRACTING PARTY. WHERE CURBS ARE PROPOSED, THE CONTRACTOR IS TO MARK THE TOP OF THE CURB WITH THE LETTER 'S' ABOVE EACH SERVICE LATERAL. 

9. RESIDENTIAL SEWER SERVICE LATERALS ARE TO BE 4 INCH SDR 35 PVC PIPES. COMMERCIAL SEWER SERVICE LATERALS ARE TO BE 6 INCH SDR 35 PVC PIPES. 

10. THE CONSTRUCTION INSPECTOR IS ANY AGENT OF THE CONTRACTING PARTY THAT HAS BEEN RETAINED TO ASSURE THAT THE WORK COVERED BY THESE PLANS IS PERFORMED CORRECTLY AND COMPLIES WITH THESE PLANS AND ANY APPLICABLE SPECIFICATIONS. 

11. IN THE PRESENCE OF THE CONSTRUCTION INSPECTOR, THE CONTRACTOR SHALL PERFORM FIVE PERCENT MANDREL DEFLECTION TESTS IN ACCORDANCE WITH ARIZONA ADMINISTRATION CODE R18-9-E301(D)(2)(I) (AND MAINTAIN RECORDS OF THE RESULTS) ON THE TOTAL LENGTH (100 %) OF ALL PVC AND/OR HDPE SEWER LINES INSTALLED. ANY SEGMENT OF PIPE FAILING THE 5 PERCENT MANDREL DEFLECTION TEST SHALL BE CORRECTED BY THE CONTRACTOR AT NO ADDITIONAL COST TO THE CONTRACTING PARTY. 

12. IN THE PRESENCE OF THE CONSTRUCTION INSPECTOR, THE CONTRACTOR SHALL PERFORM LEAKAGE TESTS IN ACCORDANCE WITH THE ARIZONA ADMINISTRATION CODE R18-9-E301 (D)(2)(j) (AND MAINTAIN RECORDS OF THE RESULTS) ON 100% OF ALL SEWER LINES INSTALLED. THE CONTRACTOR SHALL USE THE FOLLOWING APPLICABLE TEST METHOD. 

13. IN THE PRESENCE OF THE CONSTRUCTION INSPECTOR, THE CONTRACTOR SHALL PERFORM GRADE TESTS IN ACCORDANCE WITH THE ARIZONA ADMINISTRATION CODE R18-9-E301(D)(2)(K) (AND MAINTAIN RECORDS OF THE RESULTS) ON THE TOTAL LENGTH 100% OF ALL THE SEWER LINE INSTALLED FOR UNIFORM SLOPE ( BY LAMP LIGHTING, REMOTE CAMERA OR SIMILAR METHOD APPROVED BY THE UTILITY). ANY SEWER LINE THAT HAS BEEN INSTALLED AT A GRADE DIFFERENT FROM THAT CALLED FOR IN THESE PLANS, AND IS DETERMINED TO BE UNACCEPTABLE TO THE CONSTRUCTION INSPECTOR, SHALL BE RE-LAID TO THE CORRECT GRADE BY THE CONTRACTOR AT NO ADDITIONAL COST TO THE CONTRACTING PARTY. 

14. IN THE PRESENCE OF THE CONSTRUCTION INSPECTOR, THE CONTRACTOR SHALL PERFORM LEAKAGE TESTS IN ACCORDANCE WITH THE ARIZONA ADMINISTRATION CODE R18-9-E301 (D)(3)(F) (AND MAINTAIN RECORDS OF THE RESULTS) ON ALL COMPLETED MANHOLES FOLLOWING APPLICABLE TEST PROTOCOLS: ANY MANHOLE THAT FAILS THE LEAKAGE TEST BE CORRECTED AS DEEMED NECESSARY BY THE CONSTRUCTION INSPECTOR AT NO ADDITIONAL COST TO THE CONTRACTING PARTY. 

15. STATIONING IS ALONG THE CENTERLINE OF STREETS, UNLESS NOTED OTHERWISE. 

16. PER ADEQ REQUIREMENTS, A MINIMUM COVER OF 36 INCHES SHALL BE MAINTAINED OVER ALL SEWER PIPES, AS MEASURED TO FINISH GRADE, UNLESS DUCTILE IRON PIPE IS USED. 

17. ALL GRAVITY SEWER PIPE SHALL BE INSTALLED STARTING AT THE LOWEST DOWNSTREAM POINT AND THEN PIPE IS TO BE LAID AS INSTALLATION PROGRESSES UPSTREAM. THE BELL END FOR EACH LENGTH OF PIPE SHALL BE AT THE UPSTREAM END AND THE SPIGOT END SHALL BE AT THE DOWNSTREAM END. 

18. ALL SEWER SERVICES SHALL BE LAID TO THE CENTER OF THE LOT TO BE SERVED UNLESS NOTED OTHERWISE IN THE PLANS. 

19. ANY LOT, WHICH HAS A FINISH FLOOR ELEVATION LOWER THAN THE UPSTREAM  MANHOLE/CLEAN OUT RIM ELEVATION, AS DETERMINED FROM THE SEWER SERVICE  CONNECTION POINT, IS TO HAVE AN APPROVED BACKFLOW PREVENTER INSTALLED ON THAT LOT'S SEWER SERVICE LINE AT THE POINT OF TERMINATION.  

20. SEWER JOINT DEFLECTION SHALL NOT EXCEED PIPE MANUFACTURER’S RECOMMENDATION.  PIPES SHALL NOT BE DEFLECTED AT JOINTS UNLESS CALLED FOR IN THESE PLANS.  

21.  WHEN APPLICABLE, THE CONTRACTOR IS TO MARK THE TOP OF CURB WITH AN "S” AT ALL SERVICE LOCATIONS AFTER CURBS ARE INSTALLED. 

22. THE INLET AND OUTLET PIPE CONNECTIONS TO MANHOLES SHALL BE MADE BY THE USE OF FLEXIBLE COMPRESSION JOINTS NO CLOSER THAN 12 INCHES TO, AND NOT FARTHER THAN 36 INCHES FROM, THE MANHOLE WALL.  NO FLEXIBLE COMPRESSION JOINTS SHALL BE EMBEDDED IN THE MANHOLE BASE OR BENCH.
