AWWA Standard This document is an American Water Works Association AWWA standard. It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative ination normally contained in specifications. The AWWA standards usually con- tain options that must be uated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA publication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. AWWA standards are intended to represent a consensus of the water supply industry that the product described will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the classified advertising section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA publi- cation of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether that person has approved the standard or not, from manufactur- ing, marketing, purchasing, or using products, processes, or procedures not coning to the stand- ard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conity with an American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in conity with particular American National Standards. CAUTION NOTICE The American National Standards Institute ANSI approval date on the front cover of this standard indicates completion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

I. History of Standard. The original AWWA standard for sluice gates was approved as tentative in June 1941. The tentative standard was revised and approved in 1967 as AWWA Standard C501. Revisions to AWWA C501 include the following DesignationDate of Approval AWWA C501-41TJune 26, 1941 AWWA C501-67June 4, 1967 AWWA C501-80Jan. 28, 1980 AWWA C501-87June 14, 1987 II. Acceptance. In May 1985, the US Environmental Protection Agency USEPA entered into a cooperative agreement with a consortium led by NSF Inter- national NSF to develop voluntary third-party consensus standards and a certifica- tion program for all direct and indirect drinking water additives. Other members of the consortium included the American Water Works Association Research Founda- tion AWWARF, the Conference of State Health and Environmental Managers COSHEM, the American Water Works Association AWWA, and the Association of State Drinking Water Administrators ASDWA. The consortium is responsible for the cooperative effort of manufacturers, regulators, product users, and other inter- ested parties that develop and maintain the NSF standards. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.* Local agencies may choose to impose requirements more stringent than those required by the state. To uate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including 1. An advisory program erly administered by USEPA, Office of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF, ANSI†/NSF‡ 60, Drinking Water Treatment ChemicalsHealth Effects, and ANSI/NSF 61, Drinking Water System ComponentsHealth Effects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. v *Persons in Canada, Mexico, and non-North American countries should contact the appropriate authority having jurisdiction. †American National Standards Institute Inc., 11 W. 42nd St., New York, NY 10036. ‡NSF International, 3475 Plymouth Rd., Ann Arbor, MI 48106.

Various certification organizations may be involved in certifying products in accordance with ANSI/NSF 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Appendix A, “Toxicology Review and uation Procedures,” to ANSI/NSF 61 does not stipulate a maximum allowable level MAL of a contaminant for sub- stances not regulated by a USEPA final maximum contaminant level MCL. The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines noncarcinogens and risk characterization ology carcino- gens. Use of Appendix A procedures may not always be identical, depending on the certifier. AWWA C501-92 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements including applicable standards. 2. Determine the status of certifications by all parties offering to certify prod- ucts for contact with, or treatment of, drinking water. 3. Determine current ination on product certification. III. Use of This Standard. When placing orders for sluice gates to be manu- factured in accordance with this standard, the following data should be included in the purchaser’s specifications 1. Standard usedthat is, AWWA C501-92, Standard for Cast-Iron Sluice Gates. 2. Number of units required. 3. Size and type of closureconventional or -bottom. 4. If an actuator stand is needed Sec. 3.14. 5. Operating media and pressure refer to ANSI/AWWA C540, Standard for Power-Actuating Devices for Valves and Sluice Gates. 6.

If test records must be viewed Sec. 2.2. 9. Acceptable materials Sec. 2.3. 10. Design head measured from surface of water to centerline of gate, in feet metres, for the following a. Seating head. b. Unseating head. 11. Operating head measured from surface of water to centerline of gate, in feet metres. 12. Length and shape of wall thimble Sec. 3.10. 13. Rising stem or nonrising stem Sec. 3.11. 14. Type of lift mechanismmanual, electric-motor-driven, or hydraulic-cylin- der. If electric-motor-driven or hydraulic-cylinder, the purchaser should refer to ANSI/AWWA C540. 15. Omission of stem covers Sec. 3.14.5 if not required. 16.

The cast-iron sluice gates have machined metal faces and machined adjustable wedging devices. The cast-iron sluice gates may be used for square, rectangular, or round openings. They may be of the conventional-closure or the -bottom-closure type. This standard also covers manual sluice-gate actuator mechanisms together with standard accessories. Other actuator mechanisms, includ- ing electric or hydraulic mechanisms, are covered in ANSI/AWWA C540. Sec. 1.2 Definitions In this standard, the following definitions shall apply 1.2.1 Manufacturer The party that manufactures, fabricates, or produces materials or products. 1.2.2 Purchaser The person, company, or organization that purchases any materials or work to be pered. 1.2.3 Supplier The party that supplies material or
