01170.40 General - Except for class 52 or greater ductile iron pipe, m ake all service connections to
water mains, using saddles as specified and of the size and type suitable for use with both the water main and the pipe being installed. For class 52 an d greater ductile iron pipe, make direct taps for corporation stops according to the recommendations of the Ductile Iron Pipe Research Association (DIPRA), unless direct taps are prohibited by the Special Provisions. Install service pipelines perpendicular to the main, unless otherwise shown.
a.Trench Depth - Construct the depth of trench for service connection piping to provide a minimum of 30 inches of cover over the top of the pipe. Ensure that the main is not damaged during installation of the ser vice. Excavate and backfill for service connections according to Section 00405, except install the service pipeline under existing Pavement , curbs and sidewalks by boring methods approved by the agency having jurisdiction over the Roadway. Resurface the trench according to Section 00495.
b.Installation - Furnish and install water service assemblies at the locations shown, or as directed. Service pipe, meter assemblies, fittings, and appurtenances shall conform to the details and standards of the agency having jurisdiction. As shown, install the water service saddle, corporation stop, water service pipe, meter assembly, and meter, and reconnect the customer service pipe to the installed meter assembly. Cut customer service pipes using tools specifically designed to leave a smooth, even, and square end on the pipe. Ream cut ends to the full inside diameter of the pipe. For pipes that wi ll be connected using couplings that seal to the outside surface of the pipe, clean pipe ends to a sound, smooth finish before installing couplings. Make service connections to water mains according to the recommendations of the pipe manufacturer and appr opriate AWWA standard for water service installation. All water services 01170.41 1040 shall be continuous without splices between the main and the meter unless otherwise approved by the agency having jurisdiction. Install water service assemblies to match finished li nes and grades, and maintain proper clearances and cover for the entire service connection. Adjust the meter box to the finished grade after the surface has been acceptably restored. When meter boxes are to be installed in driveways or a vehicular Travel ed Way , use approved traffic rated meter boxes.
01170.41 Reconnecting Existing Services - Where shown, construct new service connections and
angle valves to reconnect existing meter assemblies to the new mains. Verify the location of existing service c onnections and meter assemblies in the field. Notify affected customers of the service interruption at least 24 hours prior to service interruption. Use insulating couplings at all connections between existing galvanized steel or iron pipe and new copper pipe. All fittings, appurtenances, and other miscellaneous materials on the sections of existing pipe that have been removed become the property of the Contractor.
01170.42 Sampling Stations - Install sampling stations according to the manufacturer's
recommendations and at the locations and depths shown or as directed. Install service connections and perform trenching , backfilling , and surface restoration according to 01170.40. Field Testing Installations
01170.50 Flushing and Disinfecting - Before tapping the main for installation of service connections
and sampling stations to existing water mains, liberally treat the exterior of the existing main with hypochlorites. Before making connections, s wab or spray the ends of all service pipe s, the connection points of all appurtenances, and the sampling stations with a 1 percent hypochlorite solution. Thoroughly flush the service connections and sampling stations. For installation of service connections and sampling stations concurrent with new water mains, flush and disinfect service connections and sampling stations according to Section 01140. 01170. 51 Hydrostatic Testing - For installation of service connections and sampling stations that connect to existing water mains, apply system pressure to new installations prior to backfilling and repair any visible leaks. For instal lation of service connections and sampling stations concurrent with new water mains, perform hydrostatic testing of service connections and sampling stations according to Section 01140. Correct all defects in M aterials or workmanship and retest until sati sfactory results are obtained. Measurement
01170.80 Measurement - The quantities of water service connection piping and water service line
will be measured on the length basis. The quantities of reconnecting existing services, sampling stations , water meter assemblies, and relocating meter assemblies will be measured on the unit basis. Payment
01170.90 Payment - The accepted quantities of Work performed under this Section will be paid for
at the Contract unit price, per unit of measurement, for the following items: 01170.90 1041 Pay Item Unit of Measurement
