SPU Water Mains and Services

A grouped feature layer that includes Water Mains, Water Services, Same Side Tap Only and No New Taps layers. Water Mains are large buried pipes that distribute water from a supply source ultimately to customer's service lines. Water Services are lines representing a water service delivered from a watermain to a property. Same Side Tap Only and No New Taps are water main restrictions which represent the availability or access to water main assets. Same Side Tap Only are lines representing where water services are only allowed to be tapped on one side of the water main. No New Taps are lines representing water mains where new water services are no longer permitted to tap into the water main. This data provides a limited view of Seattle's water infrastructure. For example, the data does not include transmission pipelines or feeder mains for reasons of water system network security. The data may show water mains that are not eligible for new water service connections (e.g., obsolete or "no-tap" water mains).本数据集为一组分组要素图层，涵盖供水干管（Water Mains）、供水支管（Water Services）、仅同侧接管（Same Side Tap Only）以及禁止新增接管（No New Taps）四类图层。供水干管指将供水源输送的水资源最终分发至用户服务管线的大型地下埋设管道；供水支管为用于表征从供水干管接驳至物业的供水服务管线。仅同侧接管与禁止新增接管均为供水干管限制类图层，用于表征供水干管资产的可用范围与接入权限：仅同侧接管图层用于标注仅允许在供水干管单侧接驳供水支管的区域；禁止新增接管图层用于标注不再允许新增供水支管接驳的供水干管。 本数据集仅呈现西雅图市供水基础设施的有限视图。 例如，出于供水系统网络安全的考量，本数据未包含输水管道与馈线干管。 此外，数据中可能包含不符合新增供水服务接驳条件的供水干管（例如老旧废弃或“禁接”类供水干管）。
