Geographic Information Systems (GIS) Section

Map-related information for the water and sewer systems operated by the City of San Diego is available through the Asset Management Program, Geographic Information Systems (GIS) Section of the Public Utilities Department.

Services provided to the public include:

  • Publicly-available GIS data - Sewer mains, manholes, water mains and water hydrants are available for download as GIS shapefiles from the SanGIS website. Other mapping data (e.g. parcels, roads, jurisdictions) are also available for viewing on the SanGIS interactive map. SanGIS also provides custom mapping services, as detailed further on the services section of their website.
  • Water service connection locations - Identification of the location of the water service location at your property. However, we do not have information regarding where private water lines are located within your private property. For that information, you may want to contact a licensed plumber. See the Your Water Plumbing System web page for more details.
  • Sewer lateral locations - Identification of the location of the sewer lateral to your property. Please note that it is the property owner's responsibility to maintain their private sewer lateral, all the way to the connection with the City's sewer main. See the Your Sewer Plumbing System web page for details.
  • Water pressure calculation - Public Utilities can provide you with a calculated estimate of the water pressure range for your property. See the Water Pressure web page for more information.
