Need to know where your pipes underground are located?

If you are excavating, drilling and/or boring you must obtain a SAWS' locate to determine underground infrastructure. SAWS will provide location information about underground infrastructure through maps or locating with physical markers, etc.

To request a locate, email

Please provide the following pertinent information:

  • Contractor/customer name, point of contact, phone numbers, email address, etc.)
  • Verify location of work (street, parkway, front, side, rear, alley, easement, etc.)
  • Work being done for: (company name, etc.)
  • Note:  Area of excavation must be white-lined.  
  • If you are a contractor and are requesting extensive/lengthy locates for multiple locations:
    • Submit by area for every block/500’
    • Provide a physical address per block
    • Identify the starting and ending point.
    • Attach pictures, map drawing to email.

Please allow 2 to 7 business days for locates requesting pipe location markers. Residential locates are only marked to the meter box, no locate on private property will be made.
