TECHNICAL REQUIREMENTS 1. To minimize the cost of providing water supply and sewerage facilities the following criteria shall apply: (a) Wherever possible, project sites will be on or adjacent to existing community water and sewer systems. (b) Unless agreed upon in advance by the IHS, project sites shall not be selected which require sewage lift stations, costly or complicated water pumping stations, sewage treatment plants or other expensive and complex utility installation. (c) Whenever possible and practicable, dwelling units within a clustered project site will be located on both sides of the street. 2. Water supplies constructed for Indian housing will provide a minimum water pressure of 15 pounds per square inch in each dwelling unit to be served, whether the supply is from a well, storage tank, spring, main or pumping plant. SPECIFIC RESPONSIBILITIES OF THE LOCAL HOUSING AUTHORITY, THE HAA, THE BIA, AND THE IHS 1. Test well drilling.-Whenever it is determined by the IHS that test drilling for wells to provide water for individual water facilities for housing projects supported by the HAA is necessary before a decision on site concurrence can be given, such test drilling shall be performed by and at the expense of the HAA program. All test drilling shall be carried out in accordance with accepted practices in the area concerned, and the data obtained shall be furnished to the IHS. The IHS will perform any test drilling required for individual wells to be provided for BIA sponsored houses, and for all community water facilities. 2. Soil percolation tests.-Whenever it is determined by the IHS that soil percolation tests are necessary to ascertain the suitability of a home site for septic tank and drainfield facilities the tests will be conducted by, or at the expense of, the IHS. The data obtained will be provided to the local housing authority. 3. Individual house facilities.-In those instances where the IHS determines that the home sites are suitable for individual water and/or waste facilities, recommendations regarding location and design of the facilities will be furnished by the IHS to the local housing authority and the HUD Regional Office. 4. Community Facilities.-When community type facilities are installed by the IHS, water mains and sewers will be extended through the streets or other public easements of the project site and lateral connections will be extended to the curb line or edge of the home site of each project structure. Curb stops will be provided and installed by the IHS on water service lines. House service lines located on the building lot will be provided by the local housing authority or, in the case of HIP housing, by the BIA. 5. On-site responsibilities. Where the IHS has agreed, after review of the house sites, that individual waste and/or water supply facilities are feasible and should be provided, the following special considerations will apply: (a) The agency financing the house construction or improvement will be responsible for the installation of all plumbing facilities within the dwelling and the service lines to a point five feet outside the building. (b) In accordance with a determination made by the Bureau of the Budget, the local housing authority will be responsible for installing any water supply and/or sewage disposal facilities which are to be located on the individual house sites for those housing units supported by funds from the HAA. These facilities would include individual water supplies, septic tank installations or service lines connecting the house to community systems. All such work is to be carried out in accordance with guides to be provided by the IHS, Item 3, above. PLAN REVIEW AND APPROVAL 1. In those instances where the housing authority is to be responsible or the installation of individual facilities on house sites, approval must be obtained from the IHS on all final plans before construction. The IHS will also inspect the construction during the installation of these facilities and upon completion of the work to assure the housing authority that the installation has been done in conformance with the plans and specifications and may be accepted. 2. If connection to a BIA water and/or sewerage system is contemplated, a joint feasibility study will be conducted by the BIA and IHS to determine the adequacy of existing facilities to meet the additional requirements, to recommend necessary improvements or additions and to determine points of master or individual metered connections, valving, flushing hydrants, etc., in order to insure compatibility with existing systems. If the system is currently inadequate, the IHS and BIA will develop a mutually agreed upon program for providing additional capacity. 3. Responsibility for the purchase of land excess to the housing needs in connection with the provision of water and sewerage facilities for HAA-assisted housing cannot be assumed by the IHS, BIA, or the НАА.
