Request For Information

Through this form, DC Water Permit Operations will provide a permit applicant with basic information on the existing water and sewer infrastructure that, in most cases, should be sufficient for design.  The types of information requests available are:

  1. Countermaps and GIS Map – Includes water & sewer countermaps, a GIS snapshot of water/sewer infrastructure around the project and tap information for the property.  Countermaps and GIS maps contain the information needed to submit a civil plan set to DC Water for review, such as sewer inverts, pipe location and structures. Note that countermaps were last updated around 2005 and information on GIS maps may supersede countermaps.  Also, our office does not have any information on sewer laterals, and limited information on water laterals.
  2. Meter Sizing Worksheet RFI – Provides information required to complete a small service Meter Sizing Worksheet: distance from main to curb in front of the property, theoretical static pressure at the main, and existing meter and service sizes.
  3. Letter in Lieu of Flow Test - For small projects with fire demand of 100 GPM or less, DC Water can provide a signed letter addressed to the Fire Marshall to be used in place of a fire hydrant flow test.  The letter includes the pressure zone, site elevation and the theoretical static pressure (psi) for a single location.   $250 payment (increase effective July 22, 2022) is required to initiate work on a Letter In Lieu of Flow Test.  Payment instructions will be provided on the confirmation email to be sent after the form is completed.

RFIs will be fulfilled by email.  Please allow 2-3 weeks for processing.

Once you have received and reviewed the Countermaps and GIS map and find your project requires additional information, you may call our office at 202-646-8600 to arrange a visit or teleconference to collect any available as-builts.  Fees may apply for the time spent researching as-builts drawings.

If you have any further questions on RFIs, please contact us by email or by phone.
