THE SEWER SYSTEM SHALL ALSO MEET THE REQUIREMENTS OF THE LATEST EDITION TO THE UNIFORM PLUMBING CODE. PIPE: UNLESS OTHERWISE SPECIFIED, ALL SANITARY SEWERS SHALL BE CONSTRUCTED OF BELL AND SPIGOT TYPE VITRIFIED CLAY PIPE EXCEPT FOR THAT PIPE USED FOR MINOR REPAIRS OR ALTERATIONS OR FOR HOUSE CONNECTION SEWERS FROM AN EXISTING MAIN. ALL VITRIFIED CLAY PIPE SHALL CONFORM TO THE APPLICABLE PROVISIONS OF THE AMERICAN SOCIETY OF TESTING MATERIALS DESIGNATION 278, CURRENTLY IN USE, AND TO THE SPECIFICATIONS ENTITLED "VITRIFIED CLAY PIPE, MATERIALS SECTION" PUBLISHED - BY THE CLAY PIPE INSTITUTE. WHERE PROVISIONS OF THESE SPECIFICATIONS ARE IN CONFLICT, THE MORE RESTRICTIVE PROVISION SHALL APPLY. VITRIFIED CLAY PIPE SHALL BE EXTRA STRENGTH CLASS AS DESIGNATED IN THE AFOREMENTIONED SPECIFICATIONS, AND SHALL BE FIRST QUALITY, DURABLE, SOUND, WELLBURNED THROUGHOUT ITS ENTIRE THICKNESS, AND SHALL GIVE A CLEAR METALLIC RING WHEN STRUCK WITH A HAMMER. PIPE 4" IN DIAMETER SHALL BE CERAMIC GLAZED ON THE INTERIOR SURFACE OF THE BARREL. PIPE 6" AND LARGER IN DIAMETER MAY BE GLAZED OR UNGLAZED AT THE CONTRACTOR'S OPTION. PRIOR TO STARTING WORK AT ANY TIME 'DURING CONSTRUCTION, THE MANUFACTURER SUPPLYING THE PIPE, IF REQUESTED BY THE ENGINEER, SHALL FURNISH CERTIFIED TEST REPORTS THAT ANY AND ALL PIPE FURNISHED MEETS THE REQUIREMENTS OF THIS SECTION. EXCAVATION: EXCAVATION SHALL INCLUDE REMOVAL OF ALL MATERIALS OF WHATEVER NATURE ENCOUNTERED, INCLUDING TREES, STONES, DEBRIS AND ABANDONED PIPES. WHEN KNOWN BY THE 'ENGINEER, LOCATIONS OF EXISTING UNDERGROUND PIPES AND IMPROVEMENTS ARE SHOWN ON THE PLANS. HOWEVER, IT IS THE CONTRACTOR'S RESPONSIBILITY TO VERIFY FROM THE VARIOUS UTILITY COMPANIES THE EXACT LOCATIONS OF THEIR IMPROVEMENTS. ALL REASONABLE PRECAUTIONS SHALL BE TAKEN TO PRESERVE AND PROTECT ANY SUCH IMPROVEMENTS WHETHER SHOWN ON THE PLANS OR NOT. THE COST OF' DAMAGES DONE FOR UNDERGROUND IMPROVEMENTS SHALL BE BORNE BY THE CONTRACTOR. THE EXCAVATION SHALL BE MADE TRUE TO LINE AND GRADE, AND SHALL BE MADE A SUFFICIENT DISTANCE BELOW THE FLOW LINE OF THE SEWER TO ALLOW FOR THE PLACING OF THE SEWER INVERT.. ALL TRENCHES SHALL BE /-,,T LEAST TWELVE (12) INCHES WIDER THAN THE OUTSIDE DIAMETER OF THE PIPE,.BUT NO WIDER THAN THE WIDTH SPECIFIED ON THE PLANS OR IN THE PROVISIONS. EXCEPT AS ALLOWED BY THE ENGINEER, THE TRENCH AT THE END OF EACH DAY SHALL NOT BE EXCAVATED MORE THAN ONE HUNDRED (100) FEET IN ADVANCE OF THE PIPE LAYING, NOR LEFT UNFILLED FOR MORE THAN ONE HUNDRED (100) FEET WHERE THE PIPE HAS BEEN LAID. THE SUBGRADE ON WHICH THE PIPE OR STRUCTURE IS TO BE PLACED SHALL BE FIRM, UNIFORM, ACCURATELY GRADED FOUNDATION. WHEN SOFT, WET, SPONGY OR ROCKY SUBGRADE IS ENCOUNTERED THE CONTRACTOR, AT HIS OWN EXPENSE, SHALL REMOVE THE UNSUITABLE MATERIAL AS DIRECTED BY THE ENGINEER AND SHALL REPLACE THE MATERIAL SO REMOVED WITH DRY, SANDY MATERIAL. ALL EXCAVATION SHALL BE MADE, PROTECTED AND SUPPORTED AS REQUIRED FOR SAFETY AND IN THE MANNER SET FORTH IN THE OPERATION RULES, ORDERS AND REGULATIONS PRESCRIBED BY THE CALIFORNIA DIVISION OF INDUSTRIAL SAFETY, BARRIERS SHALL BE PLACED AND MAINTAINED AT EACH END AND AT INTERVALS ALONG THE EXCAVATIONS AS REQUIRED TO WARN PEDESTRIAN AND VEHICULAR TRAFFIC OF THE OPEN TRENCH OR OTHER 'OBSTRUCTIONS OR HAZARDS. WARNING LIGHTS SHALL ALSO BE PLACED AND MAINTAINED ALONG THE EXCAVATION OR AT OTHER OBSTRUCTIONS OR HAZARDS FROM SUNSET TO SUNRISE EACH NIGHT. THE CONTRACTOR SHALL FURNISH, INSTALL AND OPERATE SUCH PUMPS OR OTHER DEVICES AS MAY BE NECESSARY TO REMOVE ANY SEEPAGE, STORM WATER OR SEWAGE THAT MAY BE ENCOUNTERED DURING CONSTRUCTION. THE TRENCHES AND OTHER EXCAVATIONS SHALL BE KEPT ENTIRELY FREE FROM WATER WHILE CONCRETE IS BEING PLACED OR WHILE PIPE IS BEING LAID. WATER SHALL- BE DISPOSED OF IN SUCH A MANNER AS NOT TO CAUSE INJURY TO PUBLIC OR PRIVATE PROPERTY OR BE A MENACE TO PUBLIC HEALTH. DURING EXCAVATION AND CONSTRUCTION OF THE SEWER, THE CONTRACTOR SHALL BEAR THE RESPONSIBILITY FOR DUST AND SAND CONTROL. WHENEVER THE ENGINEER DETERMINES THAT DUST OR SAND IS A NUISANCE TO THE PUBLIC THE CONTRACTOR SHALL APPLY WATER OVER THE NECESSARY AREA AND IN SUFFICIENT AMOUNTS TO ALLEVIATE THE NUISANCE. FULL COMPENSATION FOR DUST CONTROL SHALL BE CONSIDERED AS INCLUDED IN THE PRICES PAID FOR THE VARIOUS CONTRACT ITEMS OF WORK AND NO SEPARATE PAYMENT WILL BE MADE THEREFOR. HOUSE CONNECTION SEWERS: "HOUSE CONNECTION SEWER" AS USED IN THESE SPECIFICATIONS SHALL MEAN A BRANCH SEWER LAID BETWEEN THE SEWER MAIN AND THE BUILDING. HOUSE CONNECTION SEWER SHALL BE LAID ON A STANDARD GRADE OF NOT LESS THAN 2 PERCENT NOR MORE THAN 10 PERCENT. A MINIMUM GRADE OF 1 PERCENT MAY BE USED WHERE SHOWN ON THE PLANS OR WHEN SPECIFICALLY AUTHORIZED BY THE ENGINEER. THE Y BRANCHES ON THE SEWER MAIN SHALL BE INCLINED UPWARD AT AN ANGLE NOT GREATER THAN 45 DEGREES FROM A HORIZONTAL LIN E- A VITRIFIED CLAY STOPPER SHALL BE SECURELY SEALED INTO THE SOCKET OF THE LAST JOINT ON EACH HOUSE CONNECTION SEWER. WHERE A HOUSE CONNECTION SEWER IS TO BE JOINED TO AN EXISTING SEWER BY BREAKING INTO THE PIPE AND PLACING A STANDARD SADDLE, THIS SADDLE TO BE MADE OF THE SAME MATERIAL AND FOR THE PARTICULAR SIZE OF MAIN ON WHICH IT IS TO BE PLACED, BOUND IN PLACE WITH NO.. 10 (B.W.G.) GALVANIZED IRON WIRE AND. THE PIPE AND SADDLE JOINT SHALL THEN BE BANDED WITH MINIMUM 2" THICK CLASS "B" PORTLAND CEMENT CONCRETE. THE CONCRETE SHALL EXTEND A MINIMUM OF 3 INCHES FROM THE EDGE OF SADDLE. WHERE THE HOUSE CONNECTION SEWER WILL SERVE OTHER THAN SINGLE FAMILY PROPERTY THE SERVICE SHALL BE 6" DIAMETER UNLESS OTHERWISE PROVIDED. THE INVERT DEPTH AT PROPERTY LINE SHALL BE THE MAXIMUM DEPTH OBTAINED AT THE STANDARD GRADE OF 2% FROM THE MAIN EXCEPT THAT THE MAXIMUM REQUIRED DEPTH SHALL BE TEN (10) FEET BELOW THE CENTER LINE OF THE STREET OPPOSITE THE POINT OF SERVICE. UNLESS OTHERWISE PROVIDED, ALL HOUSE CONNECTION SEWERS SHALL BE CONSTRUCTED AT RIGHT ANGLES TO THE SEWER MAIN. PIPE LAYING AND JOINTING: ALL SEWERS SHALL BE LAID TRUE TO LINE AND GRADE, WITH BELLS UPGRADE. THE SECTIONS OF PIPE SHALL BE SO LAID AND JOINTED THAT, WHEN COMPLETE THE SEWER WILL HAVE A SMOOTH AND UNIFORM INVERT. VITRIFIED CLAY PIPE JOINTS SHALL BE OF THE MECHANICAL COMPRESSION TYPE EXCEPT FOR MINOR REPAIRS AND ALTERATIONS AND FOR HOUSE CONNECTION SEWERS FROM AN EXISTING MAIN. MECHANICAL COMPRESSION JOINTS SHALL BE TYPE I, II OR III AS SPECIFIED IN THE A.S.T.M., DESIGNATION C-425 IN CURRENT USE. EXCEPT FOR THE METHOD OF FIELD EX -FILTRATION TESTING, THE JOINTS SHALL CONFORM IN ALL RESPECTS TO A.S.T.M. DESIGNATION C-4251 OR 594-66T. REPAIRS, ALTERATIONS, ETC.: FOR MINOR REPAIRS, ALTERATIONS OR FOR HOUSE CONNECTION SEWERS FROM EXISTING SEWER MAINS, THE TYPE OF PIPE, TYPE OF JOINT AND THE DETAILS OF CONSTRUCTION, SHALL BE DIRECTED BY THE ENGINEER. BACKFILLING: BACKFILL MATERIAL PLACED IN THE AREA AROUND` AND TO WITHIN 12" ABOVE THE PIPE AND FROM STREET SUBGRADE TO - WITHIN 6" BELOW STREET SUBGRADE SHALL BE TERMED "SELECT. BACKFILL". SELECT BACKFILL SHALL BE FREE FROM BROKEN PAVEMENT OR CONCRETE, STONES OR LUMPS EXCEEDING I" IN' GREATEST DIMENSION, AND FROM VEGETABLE MATTER.. EXCEPT WHERE OTHERWISE SPECIFIED, BEDDING MATERIAL SHALL BE SAND, GRAVEL, CRUSHED AGGREGATE, OR NATIVE FREE -DRAINING GRANULAR MATERIAL. HAVING A SAND EQUIVALENT OF NOT LESS THAN 301, AND SHALL HAVE A PERCENTAGE COMPOSITION BY WEIGHT WHICH CONFORMS TO THE FOLLOWING GRADING: SIEVE SIZES PERCENTAGE PASSING SIEVES 2-1/2 . . . . . . . . . . 90-100 No. 4 . . . . . . . . . 35-100 BACKFILL MATERIAL WHICH IS NOT "SELECT BACKFILL" SHALL BE TERMED " COMMON BACKFILL". COMMON BACKFILL SHALL BE FREE FROM BROKEN PAVEMENT OR CONCRETE, STONES OR LUMPS EXCEEDING 6 INCHES IN GREATEST DIMENSION, VEGETABLE_ MATTER, OR OTHER UNSATISFACTORY MATERIAL. THE SELECT BACKFILL PLACED AROUND AND OVER THE PIPE SHALL BE PLACED EVENLY ON EACH SIDE OF THE PIPE FOR THE FULL WIDTH OF THE TRENCH IN LAYERS OF ABOUT 12 INCHES IN DEPTH. EACH LAYER SHALL BE THROUGHLY COMPACTED TO A RELATIVE DENSITY OF NINETY PERCENT (90%) BY THE USE OF VIBRATORY OR OTHER APPROVED COMPACTION EQUIPMENT. IN LIEU OF USING NATIVE EXCAVATED MATERIAL, THE CONTRACTOR HAS THE OPTION OF IMPORTING SLURRY TYPE PRE -MOISTENED SAND AS APPROVED BY THE ENGINEER WHICH WOULD NOT REQUIRE PLACEMENT IN 12 INCH LAYERS. THE COMPACTION REQUIREMENTS FOR SLURRY SAND BACKFILLING WILL BE THE SAME AS FOR NATIVE MATERIAL. THE EXCAVATED MATERIAL SHALL BE DISPOSED OF BY THE CONTRACTOR AWAY FROM THE JOB SITE IF IMPORTED SAND IS USED FOR BACKFILLING. PARTICULAR ATTENTION IS TO BE GIVEN THE THE UNDERSIDE OF THE PIPE AND FITTINGS TO PROVIDE A FIRM BEDDING SUPPORT ALONG THE FULL LENGTH 'OF THE PIPE. CARE SHALL BE EXERCISED IN BACKFILLING TO AVOID DAMAGE TO THE PIPE, IN ALL CASES, AFTER THE BACKFILL HAS BEEN SHAPED TO LINE AND GRADE THE PAVEMENT SUBGRADE SHALL BE MECHANICALLY COMPACTED UNTIL THE UPPER SIX (6) INCHES IS THOROUGHLY COMPACTED TO NOT LESS THAN NINETY-FIVE (95) PERCENT OF STANDARD DENSITY. (A.A.S.H.O. METHOD T99 MODIFIED) THIS OPERATION SHALL INCLUDE ANY SCARIFYING, RESHAPING, ROLLING, WETTING OR DRYING OF SUBGRADE REQUIRED TO OBTAIN PROPER COMPACTION. APPURTENANCES: ALL MANHOLES AND CLEANOUTS SHALL BE FITTED WITH STANDARD FRAMES AND COVERS AS SPECIFIED ON THE DRAWINGS. MANHOLES SHALL BE OF THE TYPE SPECIFIED ON THE DRAWINGS OR IN THE SPECIAL PROVISIONS EXCEPT THAT WHERE NO TYPE IS SPECI-FIED,' MANHOLES MAY BE EITHER OF BRICK OR PRECAST CONCRETE. NO BRICKS SHALL BE LAID NOR SHALL ANY PRECAST UNITS BE PLACED UPON THE CONCRETE FOUNDATION WITHIN 24 HOURS OF THE TIME OF THE POURING OF THE FOUNDATION. SEE STD. DETAIL 109 AT RIGHT I lStd.
