Pipe layer bond renewal

Changes to the bond requirements for sewer and utility contractors may affect you

Do you perform septic system work?

  • Contractors who install subsurface sewage treatment systems (SSTS) are licensed by the Minnesota Pollution Control Agency (MPCA).
  • Contractors licensed by MPCA don't need to file a pipe-laying bond with DLI. They will file their bond with MPCA only.
  • If you are licensed by MPCA, do not renew your bond with DLI. Submit your $25,000 SSTS bond to MPCA.

What if I don't do septic system work?

  • Contractors who install building water and sewer piping, but do not work on SSTSs, are still required to maintain a pipe-laying bond with DLI.
  • All pipe-laying bond filings expire Dec. 31, 2017.
  • Be sure to submit your new bond and renewal application forms (PDF) to DLI.
  • Mail all completed forms to:

    Minnesota Dept. of Labor and Industry
    CCLD -- Licensing Services
    443 Lafayette Road N.
    St. Paul, MN 55155

  • Providing DLI with an email address helps us communicate with you immediately if there is an issue with your renewal, allowing your application to be processed as quickly as possible.
