Sanitary - Network Features

Point features representing sanitary network features such as forcemain blowoffs and forcemain cleanouts. These network features help conveying sanitary waste under pressure from the discharge side of a pump to a discharge point. Updated as an ongoing process.本数据集包含的点特征（Point features），可用于表征市政污水管网（sanitary network）的相关设施，例如压力管放空阀（forcemain blowoffs）与压力管清通口（forcemain cleanouts）。此类管网设施可将泵（pump）出口侧受压的生活污水（sanitary waste）输送至排放点位（discharge point）。本数据集处于持续更新迭代的过程中。
