Constitution of the State of Texas 1876 Art. 3, § 49-d. Acquisition and development of water storage facilities;  filtration treatment and transportation of water or wastewater;  enlargement of reservoirs

Sec. 49-d. (a) It is hereby declared to be the policy of the State of Texas to encourage the optimum development of the limited number of feasible sites available for the construction or enlargement of dams and reservoirs for conservation of the public waters of the state, which waters are held in trust for the use and benefit of the public, and to encourage the optimum regional development of systems built for the filtration, treatment, and transmission of water and wastewater.  The proceeds from the sale of bonds deposited in the Texas Water Development Fund may be used by the Texas Water Development Board, under such provisions as the Legislature may prescribe by General Law, including the requirement of a permit for storage or beneficial use, for the additional purposes of acquiring and developing storage facilities, and any system or works necessary for the filtration, treatment and transportation of water or wastewater, or for any one or more of such purposes or methods, whether or not such a system or works is connected with a reservoir in which the state has a financial interest;  provided, however, the Texas Water Development Fund or any other state fund provided for water development, transmission, transfer or filtration shall not be used to finance any project which contemplates or results in the removal from the basin of origin of any surface water necessary to supply the reasonably foreseeable future water requirements for the next ensuing fifty-year period within the river basin of origin, except on a temporary, interim basis.

(b) Under such provisions as the Legislature may prescribe by General Law the Texas Water Development Fund may be used for the conservation and development of water for useful purposes by construction or reconstruction or enlargement of reservoirs constructed or to be constructed or enlarged within the State of Texas or on any stream constituting a boundary of the State of Texas, together with any system or works necessary for the filtration, treatment and/or transportation of water, by any one or more of the following governmental agencies:  by the United States of America or any agency, department or instrumentality thereof;  by the State of Texas or any agency, department or instrumentality thereof;  by political subdivisions or bodies politic and corporate of the state;  by interstate compact commissions to which the State of Texas is a party;  and by municipal corporations.  The Legislature shall provide terms and conditions under which the Texas Water Development Board may sell, transfer or lease, in whole or in part, any reservoir and associated system or works which the Texas Water Development Board has financed in whole or in part.

(c) Under such provisions as the Legislature may prescribe by General Law, the Texas Water Development Board may also execute long-term contracts with the United States or any of its agencies for the acquisition and development of storage facilities in reservoirs constructed or to be constructed by the Federal Government.  Such contracts when executed shall constitute general obligations of the State of Texas in the same manner and with the same effect as state bonds issued under the authority of Section 49-c of this article, and the provisions of Section 49-c of this article with respect to payment of principal and interest on state bonds issued shall likewise apply with respect to payment of principal and interest required to be paid by such contracts.  If storage facilities are acquired for a term of years, such contracts shall contain provisions for renewal that will protect the state's investment.

(d) The Legislature shall provide terms and conditions for the Texas Water Development Board to sell, transfer or lease, in whole or in part, any acquired facilities or the right to use such facilities at a price not less than the direct cost of the Board in acquiring same;  and the Legislature may provide terms and conditions for the Board to sell any unappropriated public waters of the state that might be stored in such facilities.  As a prerequisite to the purchase of such storage or water, the applicant therefor shall have secured a valid permit from the state authorizing the acquisition of such storage facilities or the water impounded therein.  The money received from any sale, transfer or lease of facilities shall be used to pay principal and interest on state bonds issued or contractual obligations incurred by the Texas Water Development Board, provided that when moneys are sufficient to pay the full amount of indebtedness then outstanding and the full amount of interest to accrue thereon, any further sums received from the sale, transfer or lease of such facilities shall be deposited and used as provided by law.  Money received from the sale of water, which shall include standby service, may be used for the operation and maintenance of acquired facilities, and for the payment of principal and interest on debt incurred.
