The pipe shall be laid in conformity to the line and grade approved for each installation. Each length of pipe shall have a true and continuous b~aring for its entire length 05 "16 50 94 between bell holes. A bell hole shall be excavated to accommodate the bell of each pipe length or fitting, of a size and depth to facilitate a complete and satisfactory placing and compaction of the joint filler. All adjustments of pipe to line and grade shall be made by scraping away or filling in and compactly tamping earth or sand under the body of the pipe. Wedging or blocking up of the pipe shall not be permitted. The bell hole shall be kept free from water during the laying of the pipe and until the Jointing , material has set sufficiently so that water thereon will cause no damage. Both bell and spigot shall be clean and care shall be taken that nothing but the joint making material enters the joint. The pipe shall be laid upgrade continuously from the connection to the sewer main to the plumbing outlet connection with the bell end forward, unless otherwise permitted, in special cases by the Sewer Inspector. A gasket of braided, untreated oakum (soaked in cement grout before placing) or a hollow rubber ring of approved type and size may be used, to center the spigot in the bell. No larger gasket shall be used than is required to prevent any mortar of the joint from escaping from the bell into the barrel of the pipe.. Mortar as described under "materials" shall then be placed and tamped uniformly and compactly the full remaining depth of the bell to the end thereof, care being taken to preserve the alignment of the pipe. Thereafter, a fillet of mortar with a water content sufficient to allow placement and spreading with a pointer trowel shall be placed and compactly trowelled entirely around the pipe and extending not less than one inch from the outer end of the bell. The completed joint shall be covered at once with moist earth or otherwise protected to prevent drying or other injury. SECTION 3.09: BACKFILL. A. Backfill over lateral sewers and main sewer connections shall be placed and thoroughly compacted under and on each side of the pipe to a depth not less than four (4) inches over the top of the pipe by means of a tamper having a cross sectional area of tamping foot not .to exceed three ,(3) square inches. The remainder of the trench shall be filled to the elevation of the surface of the adjacent ground and where water is availab~for the purpose, the filling may be compacted by flooding, except that where pavement is to be laid over it backfill above the first compacted layer above.the pipe shall be placed in horizontal layers of not to exceed one (1) foot each and compacted with tamper while being placed, and a final surface compaction with rubber-tired truck wheels shall be made. B. Backfill shall be placed and compacted within the same calendar day during which the trench cut is made for a lateral sewer except as required under Section 3.15 herein. Backfill shall be placed and compacted within the same calendar day in which the trench cut is made for a lateral sewer where a saddle has been made to the main sewer when in the judgment of. the Sewer Inspector such placing and compactlonof backfill will not damage such saddle c onneot ion. . . SECTION 3.10: PAVEMENT REPLACEMENT AND MAINTENANCE. Where any existing pavement or surfacing in any public road or traveled way open to public use must be out for the purpose of constructing any sewer, such pavement shall 'be restored to the character of improvement existing prior to making such cut. The repaving and maintenance shall include the consolidation of the pavement base, the placing of the wearing surface, and the maintenance of such , surface for a period of one (1) year after its original placing. Maintenance of paving shall include the restoration of any areas to proper grade and surfacing where such areas have settled due to subsidence of trench backfill or failure of pavement base. Pavement base shall consist of crusher run base rock conform- ing to the specifications of th~ S'tate ,of California, Division of Highways, and shall be not less than six (6) inches in thickness in any repaved trench. The pavement bas~ shall be consolidated' in the manner specified in said specifications and shall be thor- oughly keyed to adjoining undisturbed pavement base. 05 '16 50 95 Pavement surfacing shall be~f the character of the adjoining pavement, except that plant-miX7asphaltic paving materials may be placed on "armor coated" streets with the consent of the Sewer In- spector when weather conditions dictate such action. Pavement sur- facing shall be keyed and tacked to existing undisturbed surfacing. Repaving of any trench cut in which the backfill has been con- solid,ated by jetting or puddling shall not be done prior to fifteen (15) days after the backfill has been consolidated. Repaving of any trench cut in which the backfill has been con- solidated by mechanical tamping or power rolling may be done at any time after the backfill has been consolidated. SECTION 3.11: BARRIERS ~ND LIGHTS. The applicant shall maintain such barriers, lights and signs as are necessary to give warning to the public at all times while a lateral ,sewer is under construction and of any dangerous condition to be encountered in consequence thereof. He likewise shall protect ,the publj,c, in the use of walk- ways, against any such condition in connection with the construction of house sewers. SECTION 3.12: LIABILITY. The district and its officers and employees shall not be answerable for any liability for personal injury or loss of ,life or damage to any property consequent to the performance of any of the herein described work or the failure of any person to comply with any proviaion hereof. Applicant shall be solely liable for any defects in the performance of his work or any failure which may develop therein. (al SECTION 3.1):' SEWER MATERIALS. VITRIFIED PIPE. Vitrified pipe and fittings shall conform to the requirements of the American Society for Testing Materials (ASTM) Specifications for Clay Sewer Pipe, Designation C 13-40, with the exception that pipe of longer lengths will be permitted and that unglazed pipe and fittings shall be used. Pipe and fittings for side sewer construction shall'have an internal diameter of not less than four (4) inches. (b) SAND. Sand for mortar shall be natural sand composed of hard, durable, uncoated grains of rock free from oil or ,other deleter- ious material. (c) METALLIC WATER PROOFING. Metallic waterproofing for jointing mortar ' shall be "Embecoll as manufactured by Master Builders of Cleveland, Ohio, or equal. , . MORTAR. Mortar for pipe joints shall ~e composed of one part of metallic water-proofing to four parts of Portland cement to eight parts of sand proportioned by weight. (The use of 25 pounds of metallic waterproöfing to one sac~ of cement and 200 pounds of sand will give the required dry constituents for the mortar.) The mortar shall be well mixed, moistened only suffic- iently to hold it together while being placed and not so moist as to flow or be di~laoed during the process of tamping in the joint. (e) ,CEMENT. Cement for mortar shall be Portland Cement that shall conform to ASTM Specifications Designation C 150-42. ( d) ( f) SOIL PIPE. In case it is necessary for the. side sewer to be constructed beneatþ any building or within two (2) feet outside the foundation walls of such structure or in any location where it shall have less than eighteen (18) inches Qf earth cover, or thirty (30) inches of cover in any area subject to vehicular traffic, the sewer shall be constructed of cast iron soil pipe of the quality and laid with the materials and in the manner satisfying the plumbing code of the County of Contra Costa. 0 5 '16 50 96, (g) ALTERNATE SEWER PIPE AND JOINTING MATERIALS. Sewer pipe and jointing materials other than specified herein may ,be used for side sewers at the request of the owner for whom the work is being performed, but only on the approval of the Sewer Inspector for each installation. Bituminized-Fibre sewer pi~e, if used, shall be buried not less than two and one-half (2t) feet below the ground surface, and Cement-Asbestos sewer pipe, if used, shall be buried not less than e~ghteen (18) inches below the ground surface, and all connections shall be made to soil pipe with cast iron fittings and to lateral or main sewers with vitrified clay fittings. SECTION 3.14: ,CONNECTION TO MAIN SEWER. A. Lateral sewers shall be connected to the main sewer at a standard tee or wye branch, where such branch ,is installed in place in.such main sewer within three (3) feet along such sewer from the point thereon at which service is desired. , The stopper in the bell of the tee or wye shall be removed in a manner not to injure the bell, the walls and base of the bell shall be thoroughly cleaned and the ,spigot of pipe or band fitted to the bell for the required direction of the lateral. The packing and completion of the joint conneotionto the main shall not be made and completed until a sufficient length of the lateral has been laid and controlled in position by tamped earth to insure against movement of pipe in the joint during further pipe laying and joint making processes. Thereafter the sewer connection joint sijall be mortar packed and completed as pro- vided in Section 3.08 herein. B. Backfill shall be placed and tamped firm in such a manner that the completed joint will not be disturbed or injured. SECTION 3.15: SADDLE CONNECTION. In case there is no exist- ing tee or wye branch within the distance, noted in Section 3.14, from the desired point of lateral connection a saddle having a skirt fabricated therein which will prevent the entrance of the spigot of the saddle to a depth greater than the thickness of the wall of the pipe tapped shall be installed as follows: An open- ing shall be cut in the barrel of the main sewer pipe and care- fully trimmed to a snug fit of the spigot end of the saddle when centered therein with the invert of the entering lateral at the half depth of the main sewer pipe and pointing down grade on the main sewer. The exterior of the main sewer pipe shall be thor- oughly cleaned for a distance of not less than eight (8) inches along the pipe each way from the outer ëdge of the saddle skirt and for a distance around the barrel not less than three-eighths (3/8) of the outside circumference thereof each way from the center of the saddle location in case the main sewer pipe is 10" I.D. or greater, but entirely around the pipe in case the sewer is smaller than 10" I.D. The saddle then shall be mounted in the required position in mortar sufficient to give a full bearing' of the skirt of the ,saddle. on the pipe and the scarfed êdges of the opening therein. Care should be taken that no fragments of pipe or mortar are allowed to waste into the main sewer. Temporary struts shall then be placed from the bell of the saddle to trench timbering to insure security of position of the saddle. Concrete shall then be placed covering the cleaned area above described and of a depth to entirely enclose the saddle to the lip of the bell. All of the above work shall be done under the supervision and direction and to the satisfaction of the Sewer Inspector. After the completion of the concrete saddle block and not less than twenty-four (24) hours after the placing of the concrete about the saddle, connection of the lateral sewer .thereto.may be made and pipe laying therefrom continued. SECTION 3.16: SEPARATE SEWERS. Except as provided for in . this code, every house and building requiring sewer service shall be separately and independently connected with the sewer, provided, however, that where two or more buildings on the same lot belong to the same owner, separate sewer connections need not be made with the main sewer. No two separate owners of adjacent lots ~ 05 '16 50 91 . fronting on the same street shall be permitted to join in the use of the same side sewer. In case of multiple service connections under a single ownership, the Sewer Insp~ctor is authorized to require that the lateral sewer serving the house sewer or sewers shall be constructed of a size larger than four (4) inches depen- dent upon the expected capacity requirements and available grade. SECTION 3.~?: JOINT HOUSE SEWERS. When adjacent prem~es of more than one ownership require sewerage service and convenience and economy can be obtained thereby, two or more house sewers may be joined to form a single sewer provided: (1) That the portion of such sewer downstream ftom the furthest upstream junction is constructed of a size not less than six (6) inch diameter pipe or larger if determined necessary by ~he District Board; (2) Immed- iately above such junction a cleanout or standard flushing inlet is constructed in the sewer; (3) The completed sewer line, from the flushing inlet downstream to the junction with the main sewer, together with a right of way for the maintenance of said sewer and the right of entry thereto for the purpose of operation and main- tenance, is conveyed to the district. Any such sewer line shall become a part of the sewer system of the District. A properly executed grant shall be a condition prec- edent to the completion of the connection to the main sewer. SECTION 3.18: DEPTH AND GRADE OF SIDE SEWERS. Unless the conformation of the ground prevents it, side sewers shall have a depth at the street line of not less than four (4) feet between the top of the pipe and the ground surface, and shall have a uniform slope toward the main sewer of not less than one-,eighth (1/8) inch vertical to one (1) foot horizontal. The house sewer at the connec- tion ~iththe house plumbing shall be not less tha~ eighteen (18) inches below the surface of the ground, providing the minimum grade of one-eighth (1/8) inch fall per foot will permit. SECTION 3.19: CLEANOUT. There shall be a cleanout left at any right angle turn and house sewer shall terminate in a wye branch connecting with the house plumbing outlet, the straight end being close~ by a cap to be available as a cleanout. In .cases where the cleanout is thirty (30) or more inches deep, cleanout shall be brought up to within eighteen (18) inches of the ground surface. SECTION 3.20: ADDITIONAL BRANCH SEWE?S. When there is no sewer in the street on which a property requiring sewerage facilities fronts or where such required service is at an elevation impossible to be served by gravity flow to the street on which such property jonts and a private sewer is required to be constr~cted for connec- tion toa main sewer in an adjacent street, a right of way therefor shall be obtained by the District, at the expense of the owner served, before a permit for the construction of said sewer will be issued. ' SECTION 3.21: DRAINAGE CONNECTIONS PROHIBITED. No leaders from roofs and no surface drains shall be connected to any sewer. No surface or subsurface drainage or storm water shall be permitted to enter any sewer by any device or method whatever; also no spetic tanks or cesspools or the drains therefrom shall be connected to any sewer, except as noted in Section 3.25. SECTION 3.22: D~PING OF GARBAGE AND SEP'TIC TANK SLUDGE INTO MANHOLES PROHIBITED. No garbage, septic tank cleanings or any other wastes or materials shall be deposited into manholes or sewers except through approved sewer connections. The depositing of any materials into manholes from the street pr ground surface is ~ot permitted. SECTION 3.23: INDUSTRIAL WASTE PERMI~S. No person shall dis- charge any industrial waste or any garbage or any solid, semi-solid or liquid substances resulting from any industrial manufacturing or commercial process, or from any garage, service station or automobile wash-rack, into any main or lateral sewer in the District, without first having obtained a permit to do so from the District Board. 05 -16 50 98 SECTION -).24: INDUSTRIAL WASTE REGULATIONS. Permits to dis- charge any of' such substances will be granted in accordance with, and 'in consideration of, the special conditions of each case, and shall be subject to reasonable rules, regulations and requirements, to prevent excessive alkalinity or acidity of the effluent, or excessive discharge of organic or inorganic substances in solution or in suspension, whether liquid, semi-solid or solid. SECTION 3.25: SEPTIC TANKS WHEN PERMITTED.
