Allocation of Public Law 86-121 Funds

The funding for sanitation facilities construction varies from year to year, depending on the amount of funding the U.S. Congress allocates to the Indian Health Service. Other contributions are sought from various agencies such as the Navajo Nation through community development block grants or capital improvement programs, HUD grants through the Navajo Housing Authority, Bureau of Indian Affairs and the Office of Navajo-Hopi Indian Relocation Commission.

Construction of Public Law 86-121 facilities

The agreement between the Navajo Nation and the IHS to construct sanitation facilities is the Memorandum of Agreement (MOA). The enterprise of the Navajo Nation that is responsible for these construction activities is the Navajo Engineering Construction Authority (NECA). Other construction services not provided by NECA are contracted out to subcontractors.

Operation & Maintenance of Facilities

The organization responsible for the operation and maintenance (O&M) of community sanitation facilities constructed by the IHS within the Tuba City Service Unit is usually the Navajo Tribal Utility Authority (NTUA). In some smaller community systems, the O&M responsibilities are handled by the Navajo Nation’s Division of Water Resources. The homeowner accepts the O&M for individual systems, such as septic tanks and drainfields. All facilities constructed by IHS are provided with a 12-month warranty period.

How to obtain sanitation facilities for your home

A request for water and wastewater facilities for domestic use is done by application. Please come to our office and pick one up. Other available options include recommendations from chapter resolutions, medical staff, community health representatives, etc. The IHS will work within established guidelines and make every attempt to serve homeowners with individual and community sanitation facilities.
