The selection of materials is critical for water service and distribution piping in locations where there is likelihood the pipe will be exposed to signifcant concentra- tions of pollutants composed of low-molecular-weight petroleum products or organic solvents or their vapors. Documented research has shown that pipe materials such as polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers, such as those used in jointing gaskets and packing glands, are subject to permeation by low-molecular-weight organic solvents or petroleum products. If a water pipe must pass through such a contaminated area or an area subject to contamination, consult with the manufacturer regarding permeation of pipe walls, jointing materials, and so forth before selecting materials for use in that area.
4.2.1 Drawings. Te purchaser shall provide the constructor with plans and profles showing: (1) alignment and grades; (2) the locations of all outlets, con- nections, and special appurtenances; (3) working, feld-test, and surge pressures for each part of the pipeline; and (4) special details; or shall otherwise provide the constructor with information necessary for the design and manufacture of the pipe and fttings in accordance with this standard and with the specifc requirements of the work for which the pipe is made. Tis information shall be provided suf- fciently in advance of scheduled installations to allow for subsequent pipe design and manufacture.
4.2.2 Design data. Te purchaser shall specify the working pressure, feld-test pressure, and transient conditions applicable to each reach of pipeline for which the pipe shall be manufactured. Te purchaser shall also specify the external loading conditions and the method, or methods, of bedding and backflling.
4.2.3 Design responsibility. The purchaser is responsible for the overall concept and design of the pipeline project, including supporting structures. Te manufacturer is responsible for supplying pipe in accordance with the purchaser’s criteria as defned in Sec. 4.2.1 and 4.2.2.AWWA C300 pdf download.
