About this file
This document is a technical specification section (Section 53) for Reclaimed Water Systems, developed for a city engineering department. The specification provides detailed requirements for materials, pipe types, fittings, and installation standards for reclaimed water distribution systems. The document covers two primary pipe types: polyvinyl chloride (PVC) and ductile iron pipe, with minimum pressure ratings of 150 psi. Specifications include comprehensive details on pipe characteristics, joint configurations, service lines, stops, fittings, service saddles, rapid taps, and ancillary components like hose bibs and shut-off valves.
The technical specifications mandate specific material standards, including compliance with AWWA (American Water Works Association) and ANSI standards. Pipe materials must meet precise technical requirements, such as PVC pipes with a dimension ratio (DR) of 18 and ductile iron pipes with a minimum Pressure Class 150. The contractor is responsible for material procurement, storage, and quality, with provisions for potential testing and replacement of defective materials. The document specifies color coding (purple) for reclaimed water systems, detailed installation requirements, and specific manufacturer models for components like hose bibs and attachments, ensuring a comprehensive and standardized approach to reclaimed water system infrastructure.

53.1 GENERAL
These specifications cover the pipe, fittings, and accessory items used for reclaimed water distribution systems.
Pipe used for reclaimed water distribution systems shall be either polyvinyl chloride (C-900 DR18 PVC) or ductile iron pipe (DIP), minimum Pressure Class 150.
The CONTRACTOR shall be responsible for all materials furnished and storage of same, until the date of substantial completion. The CONTRACTOR shall replace, at his expense, all materials found to be defective or damaged in handling and storage. The CONTRACTOR shall, if requested by the CITY ENGINEER or designee, furnish certificates, affidavits of compliance, test reports, or samples for check analysis for any of the materials specified herein. All pipe delivered to the project site for installation is subject to random testing for compliance with the designated specifications.
53.2 PIPE INSPECTION AND TESTING
Requirements specified in Section 40 shall apply.
53.3 PVC PIPE, JOINTS, AND FITTINGS
53.3.1 PVC PIPE
All PVC pipe shall be manufactured in accordance with AWWA Standard C-900, latest edition. PVC pipe shall have a minimum working pressure rating of 150 psi and shall have a dimension ratio (DR) of 18. Pipe shall have the same outside diameter (OD) as ductile iron pipe.
53.3.2 JOINTS
PVC pipe shall have integral bell push on type joints conforming to ASTM D3139.
53.3.3 FITTINGS
Fittings used with PVC pipe shall conform to Section 53.
53.4 DUCTILE IRON PIPE AND FITTINGS
53.4.1 DUCTILE IRON PIPE
All ductile iron pipe with a nominal diameter four inches (4") through fifty four inches (54") shall conform to ANSI/AWWA A21.51/C151. A minimum Pressure Class 150 pipe shall be supplied for all sizes of pipe unless specifically called out in the drawings or required by the CITY ENGINEER or designee.
53.4.2 FITTINGS
Any fittings required shall be mechanical joint ductile iron or gray iron conforming to ANSI/AWWA A21.10/C110, 150 psi minimum pressure rating, or ductile iron compact fittings four inches (4") through twelve inches (12") in accordance with ANSI/AWWA A 21.53/C153.
53.4.3 JOINTS
Joints for ductile iron pipe and fitting joints shall be push on or mechanical joints conforming to ANSI/AWWA A21.11/C111. Where called for in the plans, restrained or flanged joints shall be provided. Flanged joints shall conform to ANSI Standard B16.1 - 125 lb. Restrained joints shall conform to Sections 34.3 and 34.4.
53.4.4 COATINGS AND LININGS
Where ductile iron pipe and fittings are to be below ground or installed in a casing pipe, the coating shall be a minimum 1.0 mil thick in accordance with ANSI A21.51. Where ductile iron pipe and fittings are to be installed above ground, pipe, fittings, and valves shall be thoroughly cleaned and given one (1) field coat (minimum 1.5 mils dry thickness) of rust inhibitor primer. Intermediate and finish field coats of alkyd shall also be applied by the CONTRACTOR (minimum 1.5 mil dry thickness each coat). Primer and field coats shall be applied in accordance with the manufacturers' recommendations. Final field coat shall be purple.
All ductile iron pipe and fittings shall have an interior protective lining of cement mortar and bituminous sealed in accordance with ANSI Standard A21.4.
