The county authority may, in any authorizing resolution of the board of directors, trust indenture or other security instrument relating to its bonds issued pursuant to this act, provide for the appointment of a trustee who shall have such powers as are provided therein to represent the registered owners of any issue of bonds in the enforcement or protection of their rights under any such resolution, trust indenture or security instrument. The county authority may also provide in such resolution, trust indenture or other security instrument that the trustee, or in the event that the trustee so appointed shall fail or decline to so protect and enforce such registered owners’ rights then such percentage of registered owners as shall be set forth in, and subject to the provisions of, such resolution, trust indenture or other security interest, may petition the court of proper jurisdiction for the appointment of a receiver of the county authority’s systems, the revenues of which are pledged to the payment of the principal of and interest on the bonds of such registered owners. Such receiver may exercise any power as may be granted in any such resolution, trust indenture or security instrument to enter upon and take possession of, acquire, construct or reconstruct or operate and maintain such system, fix charges for services of the system and enforce collection thereof, and receive all revenues derived from such system or facilities and perform the public duties and carry out the contracts and obligations of such county authority in the same manner as such county authority itself might do, all under the direction of such court.
