What Does Not Get Marked:

Private Facilities

The notified utility owner-members will not mark privately owned underground lines. These include, but are not limited to, invisible fencing, sprinkler systems, well and septic systems, their power or electric service, water and sewer pipes from the meter to your home, etc. If you have private underground lines and want them located, you should contact a private locating company before digging. Please refer to your local telephone directory for companies providing private locating services. DC Water does not mark private utility lines. 

Please visit Miss Utility for more information on their services, guidelines for safe excavation, and to submit a locate request. They are dedicated to preserving the integrity of underground utilities and ensuring the safety of our community. Remember, before you dig, call Miss Utility at 811 or 1-800-257-7777 to prevent accidents and protect essential underground infrastructure.
