Abstract

Air and blowoff valves are essential for operating, draining, flushing, and filling drinking water transmission systems, but they can be a source of cross-connection.

The San Francisco Public Utilities Commission conducted site assessments for cross-connection hazards in approximately 250 miles of transmission pipelines, with more than 1,300 air and blowoff valve appurtenances.

Benefits of this in-house project include enhanced regulatory compliance, public health protection, asset management, cost savings, and safety improvements.

空气和排气阀交叉连接控制的内部方法

空气和排污阀对于操作、排水、冲洗和填充饮用水传输系统是必不可少的，但是它们也可能是交叉连接的来源。旧金山公用事业委员会对大约250英里的输送管道进行了交叉连接危害现场评估，其中有1300多个空气和排污阀附件。该内部项目的好处包括增强法规遵从性、公共健康保护、资产管理、成本节约和安全性改进。
