对24个城市进行了一次关于当地供水系统标准的非正式调查，结果是对工程和规划所用标准进行了一次小型调查。覆盖范围包括所用管道的尺寸和类型标准、管网间距、住宅用水计算、分配水的流速和压力、铺设管道的成本、水头损失标准、消防流量标准和储存要求。这种信息的交流表明，需要一个全国性的数据库，用于水利设施规划和工程目的。包括表格，数字。

An informal inquiry of 24 cities about local water system standards resulted in a mini-survey of criteria used for engineering and planning purposes. Areas covered were standards for sizes and types of pipes used, spacing of pipeline grids, calculations of water use for residences, velocity and pressure of distributed water, costs for pipe laid, head-loss standards, fire flow standards, and storage requirements. The exchange of such information indicated a need for a nationwide data base for water utility planning and engineering purposes. Includes table, figures.
