MEGA-LUGS (OR SIMILAR PRODUCT) MAY BE REQUIRED ON ALL MECHANICAL JOINTS IN ADDITION TO CONCRETE BLOCKING. 7. ALL NEW WATER MAIN PIPES AND FITTINGS SHALL HAVE A FOAM PIPE PIG RUN THROUGH THEM PRIOR TO BEING FLUSHED, DISINFECTED, AND TESTED. CLEANING, PRESSURE AND PURITY TESTING SHALL BE DONE IN THE PRESENCE OF AND UNDER THE SUPERVISION OF A CITY OF RENTON UTILITY INSPECTOR. THE CONTRACTOR SHALL SUPPLY, INSTALL AND REMOVE PLUGS, CORPORATION STOPS, BLOW-OFF ASSEMBLIES, AND THRUST RESTRAINT / BLOCKING FOR TESTING AND PURITY ACCEPTANCE. NO CONNECTION SHALL BE MADE BETWEEN THE NEW MAIN OR BETWEEN THE NEW WET-TAP VALVE TO AN EXISTING MAIN UNTIL THE NEW PIPING HAS BEEN FOAM-PIGGED, DISINFECTED, FLUSHED, AND PASSED BOTH PRESSURE AND PURITY TESTING. 8. NEW WATER MAINS INCLUDING SERVICE LATERALS SHALL BE TESTED AT A STATIC PRESSURE OF 150 PSI ABOVE WORKING PRESSURE WITH A MINIMUM OF 225 PSI TEST PRESSURE FOR 120 MINUTES WITH A MAXIMUM OF 5 PSI PRESSURE DROP DURING THE ENTIRE TEST PERIOD. UPON SATISFACTORY COMPLETION OF THE PRESSURE TEST, THE LINE SHALL BE DISINFECTED, FLUSHED, AND THEN WATER SAMPLES SHALL BE TAKEN FOR PURITY TESTING BY THE PUBLIC WORKS INSPECTOR. 9. THE CONTRACTOR SHALL NOTIFY THE CITY OF RENTON WATER UTILITY AND MAINTENANCE DEPARTMENTS AT LEAST 10 WORKING DAYS PRIOR TO MAKING CONNECTIONS TO THE EXISTING WATER SYSTEM. THE CONTRACTOR SHALL EXPOSE THE EXISTING WATER MAIN AND FITTINGS AT THE CONNECTION POINT BEFORE ORDERING THE NECESSARY ADAPTORS AND FITTINGS REQUIRED FOR THE FINAL CONNECTION. THE CONTRACTOR SHALL EXCAVATE, REMOVE ALL SURFACE MATERIALS, AND PROVIDE SHORING AND ALL MATERIALS REQUIRED FOR THE CITY OF RENTON TO PERFORM THE CONNECTION TO THE EXISTING WATER SYSTEM.

The SS pipe is the slurry pipe shown in yellow. #3 18" vertical separation is required. It seems that 18" by design is achievable. Verify thrust block is not pushing against proposed SD pipe #2 If power is crossing over water- tint concrete slurry RED and encase power to extend beyond water trench limits. #1 10' min separation between water and building- call out #5 This thrust block is allowed as shown as long as the soil behind block is undisturbed. REVISED WATER COMMENTS ERIC F. OTT 8/10/2017 PUBLIC WORKS UTILITY ENGINEER-WATERAPPROVED WITH THE FOLLOWING CONDITIONS. 1.The alignment for the proposed water main may not be installed within 10’ of the proposed building. Design need to dimension distance. 2.The proposed power crossing over the proposed water, the power must be encased within a 4” thick RED tinted concrete encasement. The engineer calls out to lower the water line for 12” min clearance which is acceptable but the depth may not exceed 6.5’ 3.18” vertical separation is required between the proposed water and proposed SD. Looking at the IE of SD and slope. There should be sufficient grade to achieve 18” by design. The proposed bend for the water main needs to be called out: provide N/E. Call out: THE THRUST BLOCK SHALL BE INSTALLED AGAINST UNDISTURBED SOIL. 4.The proposed sewer main is less than 18” vertical separation to the existing water main, therefore the engineer has two options: Install water quality C900 pipe for the sewer run (or) encase the SS pipe with 4” thick concrete slurry to 10’ lateral separation from the existing water main. 5.The use of a geotechnical engineer is not required as long as the proposed thrust block is pushing against undisturbed soil and installed per city standards drawings.
