JUC Reclaimed Main The installation of reclaimed water piping shall be similar to that of potable water piping and as specified below. Special identification and appurtenances shall be required in the installation of reclaimed water pipe to eliminate the possibility of cross connections, backflow or the in advertent use of non-potable water for potable purposes. 1. Materials Reclaimed water pipe installed shall be pressure rated polyvinyl chloride (PVC) plastic pipe meeting the applicable requirements of AWWA C900-81. The pipe pressure rating shall be for pressure class 150 psi (DR-18). The pipe shall be delivered with rubber gasketed separate couplings meeting AWWA C900-81 with integral bell ends meeting ASTM D 3139. Fittings shall be cast iron conforming to AWWA C-100 for 250 psi working pressure. Flanged ends shall conform to AWWA C-110. Push-on and mechanical joint ends shall conform to AWWA C-111. Fittings shall be mortar lined and coal tar coated in accordance with AWWA C-104. 2. Trench Excavation, Backfilling and Compaction Trench excavation, backfilling and compaction shall be as specified in Maricopa Association of Governments (MAG) Standard Specifications Section 601. A. Pipe Separation (Potable Water): Where reclaimed water mains are installed in the vicinity of existing water mains or building water connections, the reclaimed water lines shall conform to MAG requirements for sewer lines. B. Pipe Separation (Sewers): Where reclaimed water mains are installed in the vicinity of existing sanitary sewers or building sewer connections, the reclaimed water lines shall conform to MAG requirements for potable water lines. 3. Pipe Identification The following pipeline identification methods from reclaimed water piping systems shall be required for all instructions: A. Warning Tape: Metallic, detectable warning tape on pipelines shall have a green field the words "CAUTION - RECLAIMED (OR NON-POTABLE) WATERLINE" in black. The overall width shall be three inches. Warning tapes shall be installed one foot above the top of the pipe longitudinally and centered. The warning tape shall be continuous over the entire length of the pipe. B. Pipe Marking: Pipes shall be marked by one of the following methods: 1. Stenciled Pipe: The words, "RECLAIMED (OR NON-POTABLE) WATER" shall be stenciled in two inch green letters in two places on the pipe in at least five areas of a twenty foot section of pipe for a total of ten places per section of pipe. Stenciled PVC irrigation pipe (service lines) shall be white with green stenciling. The stenciling shall appear on both sides of the pipe with the marking, "RECLAIMED (OR NON-POTABLE) WATER," in 5/8-inch letters repeated every twelve inches. 2. Vinyl Tape: As an alternative to stenciling, all pipe 2.5 inches in diameter and larger may be identified by paperbacked adhesive vinyl tape. The tape shall be six inches wide with a green background and black letters one-inch high. The wording, "RECLAIMED (OR NON-POTABLE) WATER MAIN" shall be placed longitudinally on the pipe. For 2.5 inch through four-inch pipe, the tape shall be centered along the top of the pipe; for six inch through 16-inch pipe, the tape shall be placed on both sides of the top half of the pipe. For 20 inch and larger pipe, the tape shall be placed as on the six inch through 16-inch pipe with a third strip along the center of the top of the pipe. The tape shall be placed from joint to joint. C. Warning signs: Reclaimed water lines shall be identified by surface mounted signs, at least six inches square, with the following message in bold, black letters on a white background: "WARNING - RECLAIMED WASTEWATER - DO NOT DRINK" signs shall be prominently located in all areas subject to irrigation. At all lakes at pedestrian entrances or access points, at all hose bibs, and spaced at 100 yard maximum between signs, except for roadway medians, where signs may be spaced at 300 yard intervals. 4. System Appurtenances The appurtenances in the reclaimed water system shall be identified and safeguarded as follows: A. Fire Hydrants: Reclaimed water fire hydrants shall have rocker-lug type caps; pentagon nut caps shall not be used. Hydrants shall be painted aluminum and gloss black. The bonnets and barrel shall be painted aluminum in color, with the top most three inches painted gloss black. The initials of the hydrant owner(s) shall be stenciled in three-inch gloss black letters on the front of the hydrant barrel. B. Valves: Valves shall be equipped with standard cast iron roadway boxes and shall be three-piece, slip type, with square covered painted red. Valve box covers are cast with the word "RECLAIMED OR NON POTABLE WATER." The valves shall operate by means of a recessed key slot or by means of hexagonal heads, which require a special tool to exercise the valve. C. Meter Boxes: Box lids shall be cast with the words, "RECLAIMED (OR NON-POTABLE) WATER." Meter boxes shall be pre-cast concrete with stamped steel lids. 5. Fire Hydrants Fire hydrants furnished by the contractor shall conform to the requirements of MAG Section 756 and Chandler Standard Detail 50 subject to a modification of the operating nut and painting schedule described in paragraph 4(a) above. 6. Valves Valves and valve covers shall be furnished by the Contractor as specified in MAG Section 610.6, subject to the modifications listed in paragraph 4(B) above. 7. Testing The procedures for testing the pipes water tightness shall be as specified in MAG Section 610.14 with the exception that reclaimed water shall be used in lieu of potable water to fill the pipe section being tested. Disinfection of reclaimed water mains shall not be required. 8. Construction Methods All reclaimed water pipe shall be installed as specified in MAG Section 610.4 and in accordance with manufacturer's recommendations. The Policy/Procedure P-222 shall also be adhered to (see Appendix A). 9. Storage of PVC Pipe PVC pipe stored on-site shall not be exposed to direct ultraviolet radiation, and the screening shall be placed to allow sufficient air circulation air circulation and ventilation of the pipe.
