Where specific installation is not indicated, follow piping manufacturer's written instructions. STORM UTILITY DRAINAGE PIPING 334100-3
D. 2.12 2.13 2.14 Install piping beginning at low point, true to grades and alignment indicated with unbroken continuity of invert. Place bell ends of piping facing upstream. Install gaskets, seals, sleeves, and couplings according to manufacturer's written instructions for use of lubricants, cements, and other installation requirements. Install proper size increasers, reducers, and couplings where different sizes or materials of pipes and fittings are connected. Reducing size of piping in direction of flow is prohibited. Install gravity-flow, non-pressure drainage piping according to the following: 1. Install piping pitched down in direction of flow. 2. Install PVC sewer piping according to ASTM D 2321 and ASTM F 1668. CLEANOUT AND FLOOR DRAIN INSTALLATION Install cleanouts, floor drains and riser extensions from sewer pipes to cleanouts at grade. Use PVC fittings in storm sewer pipes at branches for cleanouts and floor drains and PVC pipe for riser extensions to cleanouts and floor drains. Install piping so floor drains and cleanouts open in direction of flow in storm sewer pipe. Set cleanout frames and covers in concrete floor with tops flush with floor surface. Set floor drain frames and covers in the concrete floors to the elevations shown on the plan and flush with the surrounding concrete floor. DRAIN BASIN INSTALLATION General: Install drain basins, complete with appurtenances and accessories indicated. Where specific drain basin construction is not indicated, follow drain basin manufacturer's written instructions. Set tops of frames and covers flush with finished surface surrounding the drain basin. CONNECTIONS Connect non-pressure, gravity-flow drainage piping in building's storm building drains. Make connections to piping and drain basins. 1. Use commercially manufactured wye fittings for piping branch connections. 2. Remove debris or other extraneous material that may accumulate. Connect to sediment interceptors specified in Division 22 Section "Sanitary Waste Interceptors." D. Pipe couplings and expansion joints with pressure ratings at least equal to piping rating may be used in applications below unless otherwise indicated. 1. Use non-pressure-type flexible couplings where required to join gravity-flow, nonpressure sewer piping unless otherwise indicated. a. Unshielded, flexible couplings for same or minor difference OD pipes. b. Unshielded, increaser/reducer-pattern, flexible couplings for pipes with different OD. c. Ring-type flexible couplings for piping of different sizes where annular space between smaller piping's OD and larger piping's ID permits installation. STORM UTILITY DRAINAGE PIPING 334100-4
2.15 2.16 IDENTIFICATION Furnish and install green warning tape directly over piping and at outside edge of underground structures. 1. Use detectable warning tape over nonferrous piping and over edges of underground structures. FIELD QUALITY CONTROL Inspect interior of piping to determine whether line displacement or other damage has occurred. 1. Submit separate reports for each system inspection. 2. Defects requiring correction include the following: a. Alignment: Less than full diameter of inside of pipe is visible between structures. b. Deflection: Flexible piping with deflection that prevents passage of ball or cylinder of size not less than 92.5 percent of piping diameter. c. Damage: Crushed, broken, cracked, or otherwise damaged piping. d. Infiltration: Water leakage into piping. e. Exfiltration: Water leakage from or around piping. 3. Replace defective piping using new materials, and repeat inspections until defects are within allowances specified. 4. Re-inspect and repeat procedure until results are satisfactory. Test new piping systems, and parts of existing systems that have been altered, extended, or repaired, for leaks and defects. 1. Do not enclose, cover, or put into service before inspection and approval. 2. Schedule tests and inspections with at least 24 hours' advance notice. 3. Submit separate report for each test. 4. Gravity-Flow Storm Drainage Piping: Test according to requirements of UNI-B-6, and the following: a. Test plastic piping according to ASTM F 1417. Leaks and loss in test pressure constitute defects that must be repaired. D. Replace leaking piping using new materials, and repeat testing until leakage is within allowances specified.
