Navajo Tribal Utility Authority – an enterprise of the Navajo Nation
Lists of licensed plumbers, septic service and electric providers

To assist our residential customers with their utility service needs, the NTUA has developed a list of Electrical, Plumbing, and Septic Tank Contractors that can provide services in and around your home.  Contractors are listed within each NTUA district service area, however, many businesses may overlap these boundaries.
Please note that NTUA is merely providing the attached lists of contractors and does not assume responsibility for work performed by said contractors, nor does it recommend any particular contractor. 

If you have any questions, contact your local NTUA office:1-800-528-5011
