Utility Permits

The Town of Knightdale merged its Water & Sewer System with the City of Raleigh in 2006. As such, Raleigh Water owns and operates all public water and wastewater systems that provide service to residents and businesses within the urban service area in the Town of Knightdale. The Town retains authority as to when and where new water and sewer services can be extended to support growth and development within its planning and zoning jurisdiction, subject to conditions in the inter-local agreement. 

  • This is the starting point for developers, engineers, and residents who seek information about water and sewer availability and connection.
  • To find out if water and/or sewer service is available, please email water.review@raleighnc.gov
    • Include the address, what utilities you plan to connect to, and the desired size/type of service
  • Water-only connections may be allowed. Sewer-only connections are generally not permitted, except in specific situations related to public health.
  • Private services must be directly tapped to available public water or sewer main. In cases where this is not possible, public water mains and sewer mains may be extended at the expense of the applicant.
  • Connection to public utilities requires the submittal of an annexation petition into Knightdale Town Limits

As of June 1, 2025, all applications for water and sewer connections (utility permits) are submitted on the City of Raleigh's Permit and Development Portal.

  • Prior to applying for a water and/or sewer service connection with the City of Raleigh, you must have an approved plumbing or building permit from Knightdale (via Wake County Permit Portal). You will be prompted to provide the permit number when filling out the utility connection application. 
  • After logging into Raleigh's Portal, search for and select the "Request for water and sewer connections in Knightdale" appplication. 
  • New Construction (Residential & Commercial): Builders/property owners are responsible for submiting a water/sewer connection permit application after trade or building permit issuance. Connection permits will not be issued until City of Raleigh has accepted all water and sewer infrastructure.
  • New Connections for Existing Houses or Businesses: If water and sewer are available and you choose to connect, you must apply for a connection permit after the Town Council acts on the required annexation petition.

See City of Raleigh's website for additional information. 

  • Irrigation connections require both a City of Raleigh utility permit (submitted via City of Raleigh's Permit and Development Portal) and a plumbing trade permit (submitted via the Wake County Permit Portal)
  • The plumbing trade permit submittal must include the following information:
    • Site Plan: include location of proposed sprinkler heads, meters, and other system components
      • all heads should be located on private property, not in the public right-of-way
    • Service Type: new line/meter OR a split from existing meter
    • Meter Size: If not using the existing meter, indicate the proposed size of the irrigation meter
    • Contractor Information:
      • Licensed Utility Contractor - required when working in the right-of-way or public easements
      • Licensed Plumbing Contractor
    • Backflow - must be an approved model. See City of Raleigh's Cross Connection Program for additional information.
  • Once Knightdale staff has received all required information, the plumbing trade permit will be issued via the Wake County Permit Portal.
  • The applicant is then responsible for applying for the utility connection permit via City of Raleigh's Permit and Development Portal using the "Request for water and sewer connections in Knightdale" appplication. 

After the Utility Connection Permit is applied for and approved, applicable fees will be invoiced. All fees must be paid via the Raleigh Permit and Development Portal.

  • The following Raleigh Water Fees can apply to your project:
    • Capital Facilities Fees – Applied if making a direct tap on the main for irrigation or if splitting of a fire line.
    • Meter fees
    • Tap fees for City-installed taps
    • Stub fee (Only applies for taps installed by Licensed Utility Contractor)
