WATER UTILITY DISTRIBUTION PIPING
|Publication Date:||1 February 2018|
This guide specification covers the requirements for potable and non-potable (i.e., raw water, sea, salt water) systems, in which the largest size pipe is 1200 mm 60 inches in diameter and the maximum system working pressure is 1000 kPa 150 psi. This maximum working pressure depends on piping materials and appurtenances listed in this specification. Ensure that the pressure class of piping materials and appurtenances exceeds the maximum working pressure of the system. This section covers water systems for use outside of buildings, including water mains, water transmission mains and water service lines to a point approximately 1.5 m 5 feet from the perimeter of buildings or structures.. Water lines within 1.5 m 5 feet of the building are typically covered by Division 22 specifications and occasionally Division 40 specifications.
When control systems are used to monitor water utility systems include Section 25 05 11 CYBERSECURITY FOR FACILITY-RELATED CONTROL SYSTEMS.
For areas outside of the United States (U.S.), U.S. Territories and Possessions determine if required materials are suitable or if an equivalent host nation standard is required. Design must comply with the applicable U.S. & Host Nation norms, regulations and all applicable U.S. Military criteria. Where a host nation standard is required, an equivalent host nation standard may supersede the required material indicated in this specification. Equivalency and compliance statement in duel languages must be provided and certified by the Host Nation engineer, registered on the country's professional rolls.
For corrosive soils select materials, coatings or cathodic protection systems in accordance with UFC 3-230-01. When cathodic protection is used include Section 26 42 13.00 20 CATHODIC PROTECTION BY When piping is beneath open piers and other exposed locations is subject to freezing temperatures, include requirements for insulation and protective coverings in the project specification. Information on this subject related to open piers may be found in Technical Report R593, September 1968, "Freeze Protection for Freshwater and Sanitary Piping Under Open Piers," by the Naval Facilities Engineering Services Center, 560 Center Drive, Port Hueneme, California 93043-4328.
