Seattle Water Infrastructure Mains and Service Restrictions

Seattle's water infrastructure data includes Water Mains, Water Services, and restriction layers for Same Side Tap Only and No New Taps. The dataset provides a limited view of the city's water distribution network, excluding transmission pipelines for security reasons. It is published by the City of Seattle and was last updated in March 2026.

Use Cases

• Map Water Mains and Water Services to analyze the spatial distribution of the city's water network.
• Identify water main restrictions by analyzing the No New Taps layer to locate mains where new service connections are prohibited.
• Plan utility work by examining the Same Side Tap Only layer to understand service connection limitations on specific water mains.

Strengths

• Published by the City of Seattle, an authoritative municipal source.
• Includes multiple data layers (Water Mains, Water Services, Same Side Tap Only, No New Taps) for a multi-faceted view.
• Available in multiple geospatial formats including GeoPackage and GeoJSON for interoperability.

Limitations

• The dataset provides a limited view, explicitly excluding transmission pipelines and feeder mains for security reasons.
• Data may include obsolete or 'no-tap' water mains that are not eligible for new connections.
• Row count, column count, and specific temporal coverage are unknown from the provided input.
