Tex. Auxiliary Water Laws § 2

Any water power control district is authorized to issue revenue bonds, without an election, for the purpose of the construction and acquisition of pipe lines, pumps and all facilities necessary for the sale or disposal of salt water for pollution control. Any such bonds shall be authorized by such Board of Directors, from time to time, and in such amounts as it shall consider necessary. All such bonds shall be fully negotiable and may be made redeemable before maturity, at the option of the Board of Directors of any such District, at such price or prices and under such terms and conditions as may be fixed by such Board of Directors prior to the issuance of such bonds. Such Board of Directors may sell such bonds in such manner, either at public or at private sale, and for such price as it may determine to be for the best interest of the District, but no such sale shall be made at a price so low as to require the payment of interest on the money received therefor at more than six (6%) per cent per annum, computed with relation to the absolute maturity of the bonds in accordance with standard tables of bond values, excluding however, from such computation the amount of any premium to be paid on redemption of any bonds prior to maturity. Subject to the restrictions contained in this Act each such Board of Directors is given complete discretion in fixing the form, conditions and details of such bonds, and such bonds may be refunded or otherwise refinanced whenever said Board of Directors deems such action to be appropriate or necessary.

Any such bonds may be secured by a pledge of the revenues to be received by the District from one or more contracts entered into between the District and any person, firm or corporation, in the manner and to the extent provided in the order of the Board of Directors authorizing such bonds. Any such bonds shall be special obligations of the District issuing same, payable solely from the revenues pledged to their payment. Any such bonds shall contain the following statement:

"The holder hereof shall never have the right to demand payment hereof from funds raised or to be raised by taxation."
