Summary: Agricultural Water Conservation Act of 1993 - Amends the Internal Revenue Code to allow a tax credit for 75 percent of the water conservation system expenses for the purchase and installation of materials or equipment to substantially conserve water on farm land.

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Agricultural Water Conservation Act 
of 1993''.

SEC. 2. CONGRESSIONAL FINDINGS.

    The Congress finds that--
            (1) the Federal Government has an historic commitment to 
        assisting areas of the Nation in need of developing adequate 
        water supplies,
            (2) water is becoming increasingly scarce and expensive in 
        many parts of the United States, which is compounded when 
        multiple years of drought occur,
            (3) in most areas of the United States, farms are 
        overwhelmingly the largest water consumers, and
            (4) it is in the national interest for farmers to implement 
        water conservation measures which are a least-cost approach to 
        addressing critical water needs and for the Federal Government 
        to promote such conservation measures.

              SYSTEMS ON FARM LAND.
