Water and Sewer Availability Certificate

What does it mean? DC Water does not issue building permits. Building permits are processed and issued by DCRA. However, in order to obtain a building permit when a connection to the public water and/or sewer mains is required, the applicant must obtain a Water and Sewer Availability Certificate (WSAC) from DC Water. The WSAC is the final approval document that the applicant will receive from DC Water. It signifies that the plans are in accordance with DC Water's design requirements and guidelines and all fees have been paid.
Does this apply to me? A WSAC is completed for all projects that entail a connection to the water and/or sewer system, a temporary water connection, the raze of an existing building, a foundation to grade permit, or a sheeting and shoring permit.
When do I apply?
  1. First, the applicant must first obtain approval from DDOE for Erosion & Sediment Control and/or Stormwater Management.
  2. Second, the applicant must provide DC Water with a copy or scan of the approved sheets from DDOE.
  3. Third, the applicant must apply for a building permit application from DCRA.
  4. Forth, the plans must obtain preliminary approval from DC Water staff for general conformance with DC Water design standards.
  5. Fifth, the applicant will be provided a estimate for inspection fees and deposits by the DC Water reviewer to be paid prior to release of the plans
  6. Once the above steps are complete the applicant will receive stamped plans, receipt for paid fees and the Water and Sewer Availability Certificate (WSAC).
What do I need to submit?
  1. One copy of pages 1 and 2 from the DCRA Building Permit Application
  2. Four full size bond copies of the approved Preliminary Plans stamped and signed by DC Water
  3. One full size bond copy of the stamped approved ESC/SWM plans from the DDOE
