Critical dimensions, jointing and connections, fasteners and anchors. 3. Materials of constructions. C. Sizes, spacing, and locations of structural components, connectors, attachments, adjustments, openings, and fasteners. D. Samples: Six (6) inch square sample of fiberglass reinforced plastic laminate at the proper thickness and produced in the same manner as the molded trough. E. Manufacturer’s installation instructions. 1.5 Delivery, Storage, and Handling A. Manufacturer will provide the product banded on skids or other suitable packaging for ease of handling and minimize damage during shipping. At the project site, store the product indoors out of the way of construction activities. PART 2 PRODUCTS 2.1 Manufacturer A. MFG Water Treatment Products Company, 55 Fourth Avenue, Union City, Pennsylvania 16438. A. Manufacturer and supplier of the troughs shall be NSF 61 Certified. B. Manufacturer and supplier will need to supply a performance bond. C. No Substitutions. 2.2 Wash Troughs A. Material: Laminated fiberglass reinforced Isophthalic polyester resin, nominal ¼ inch thickness; inside surface shall have a smooth gel-coat resin finish; outside surface gel-coat resin seals exposed glass fibers; color molded-in with ultraviolet inhibitor. All cut edges shall be sealed with polyester resin. 1. Glass Type E, random chopped with chrome or silane finish, a binder compatible with the resin, glass strand length one (1) inch minimum. 2. Adequate contact molding pressure ensures complete resin wet-out of glassfibers. 3. Fiberglass fiber weight, nominal 25 percent. 4. Physical Properties: Per AWWA PAGE 3 SECTION 11201 TROUGHS a. Tensile Strength (ASTM D-638): 12,000 psi, minimum b. Flexural Strength (ASTM D-790): 19,000 psi, minimum c. Flexural Modulus (ASTM D-790): 900,000 psi, minimum d.

Construction: Meet requirements of ANSI/AWWA F101 and ANSI/NSF 61; supply NSF labeled products and proof of certification. 1. Design to support the applied downward vertical or gravity loadings: a. Fabrication b. Attachments c. Water fill 2. Design to resist buoyant or gravity water load deflection, maximum upward and downward deflection equal to or less than L / 1000 where L represents the unsupported trough length in inches; maximum vertical deflection at trough mid-point between supports not to exceed 3/16 inches. 3. Round, square or “V” bottoms for trough with vertical sides. 4. Top edge straight with no more than 1/8 inch deviation from true plane. 5. Unit rigidity; longitudinal steel stiffening ribs integrally molded in as required. 6. Sufficient number of PVC spreader bars maintains uniform width over length of each trough. 7. Open end condition: (select one) a. A two (2) inch wide, ½ inch thick wall, grouting rib molded outside of each trough at the gullet end acts as water stop when trough grouted in place. b. A saddle at trough end with slotted holes to allow a minimum vertical adjustment of one (1) inch. 8. Closed end of trough when integrally molded in, should be 1.5 times thickness of trough body. 9. If required by specifications: Weir Plates; match-metal-die-molded (ANSI/AWWA F102) fiberglass reinforced plastic, V-notch design and specified depth, ¼ inch nominal thickness, appropriate number of 2-1/2 inch diameter holes on design specific centers. (See specification Weirs, Baffles and Baffle Supports) 10. Stainless steel spacer rods, in lieu of PVC spacer rods. 11. Fasteners and anchors; (Select one) a. Type 304 stainless steel. b. Type 316 stainless steel. PAGE 4 SECTION 11201 TROUGHS PART 3 EXECUTION 3.1 Examination A. Trough dimensions require verification and project site conditions must be suitable for installation. Unsatisfactory site conditions must be corrected before product installation. 3.2 Installation A. Products are to be installed as specified by the manufacturer, as shown in contract documents and in true and proper alignment. B. Adjust weir plates per contract documents or as directed by the site Engineer. C. Grout trough in place after leveling. D. When necessary to adjust lengths of plates due to field conditions and when approved by the site Engineer, seal cut or machined edges thus exposed with manufacturer’s supplied sealant. Excessive cutting will not be acceptable. 3.3 Adjust and Clean A. Surfaces to be cleaned according to manufacturer’s instructions. B. Remove excess materials of construction and trash to leave site in a clean condition for subsequent operation. END OF SECTION
