Piping: Prior to installation, verify that insides of pipe and pipe joints are clean and free of dirt, mud, oil, shavings from cutting, or other deleterious materials. 3.2 INSTALLATION A. General: Completed storm sewer system shall comply with City. In case of conflict between the City requirements and the requirements specified herein, the City requirements shall govern. B. Piping – General: 1. Use only undamaged material. 2. Lay pipe on firm bedding with full length of barrel fully supported. Maintain straight lines and uniform grades between invert elevations shown. Inside of pipe shall be smooth and clean. 3. Begin all pipe installation at downstream end of pipe run, with lower segment of pipe in contact with specified bedding. Place bell or groove ends facing upstream. 4. Plug ends temporarily during installation, until connections are made to adjoining pipe or to manholes or inlet structures. 5. Trench excavation and placement and compaction of bedding and backfill is specified in Section 02225. C. Manholes: 1. Construct manholes in accordance with drawings and applicable public works standards. Carry pipe through manhole with split pipe. Extend cast-in-place concrete manhole base at least 8” below pipe barrel. 2. Slope floor of manhole from centerline of pipe to maximum of 2” above top of pipe at face of manhole. Shape invert when manhole base is poured to conform exactly to lower half of pipe. 3. Form or shape inverts smooth and clean, with no obstructions. Allow insertion of an expandable plug in pipe. Construct side branches with radii as large as possible to connect to main invert. 4. Extend concrete base ring minimum 3” above top of pipe. 5. Place future extension of pipe from manholes in manhole base. Shape invert with pipe extended to outside face of manhole base and terminated with bell of pipe as close as practical to manhole base. April 2020 City of Edgewater 26th Ave and Fenton Street Storm Sewer Project 02720 - 6 6. Do not place precast manhole sections on manhole base for two days minimum after placement of concrete base. Thoroughly clean top of formed concrete base ring prior to placing manhole barrel sections. 7. Place a complete and continuous roll of sealant in groove or keyway of concrete base ring in sufficient quantity that when precast manhole barrel is placed there will be no voids. Join each succeeding precast manhole barrel in similar manner. Install sealant in groove side of tongue and groove joints. 8. Trim away all excess material and repair all lifting holes. D. Manhole Ring and Covers: 1. Set ring and cover at same grade as road or other finished surface. 2. Where finished surface will be completed after manhole construction, set top of cone where a maximum of two courses of brick will be required to adjust ring and cover to final grade. Final elevations of lid will be adjusted with bricks, mortar or precast concrete rings not to exceed 6”. E. Inlets, Outlets, and Catch Basins: 1. Cast-in-place or precast concrete in accordance with drawings and applicable public works standards. Comply with applicable requirements of Section 03300. 2. Construct inverts of pipe or concrete smoothed inverts same size as pipe up to centerline of pipe. Form perimeter bench as indicated. 3.

Clear interior of piping and structures of dirt and superfluous material as work progresses. 1. In large, accessible piping, brushes and brooms may be used for cleaning. 2. Place plug in end of incomplete piping at end of day and when work stops. 3. Flush piping between manholes and other structures to remove collected debris. B. Inspect interior of piping to determine whether line displacement or other damage has occurred. Inspect after approximately 24 inches of backfill is in place, and again at completion of Project.

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. Reinspect and repeat procedure until results are satisfactory. C. Test new piping systems for leaks and defects. 1. Do not enclose, cover, or put into service before inspection and approval. 2. Test completed piping systems according to authorities having jurisdiction. a. Testing: Hydrostatic pressure tests on joints shall be made on an assembly of two section of pipe, properly connected in accordance with the joint design. Suitable bulkheads shall be provided either within the pipe adjacent to and on either side of the joint, or at the outer ends of the two joined pipe sections. No mortar or concrete coatings, fillings, or packings shall be placed prior to watertightness tests. After the pipe sections are fitted together with the gaskets or gaskets in place, the assembly shall be subjected to an internal hydrostatic pressure of 13 psi (30 ft.) pressure head for 10 minutes. Moisture or beads of water appearing on the surface of the joint will not be considered as leakage. If leakage of joints should initially occur, the Contractor shall have the option to extend the test period up to 24 hours. 3. Schedule tests and inspections by authorities having jurisdiction with at least 24 hours' advance notice. 4. Submit separate reports for each test. 5. Leaks and loss in test pressure constitute defects that must be repaired. 6. Replace leaking piping using new materials, and repeat testing until leakage is within allowances specified. END OF SECTION
