(a) Unless otherwise specified, a utility or a water supply or sewer service corporation may not in any way provide retail water or sewer utility service directly or indirectly to the public without first having obtained from the commission a certificate of convenience and necessity (CCN). Except as otherwise provided by this subchapter, a retail public utility may not provide, make available, or extend retail water or sewer utility service to any area to which retail water or sewer utility service is being lawfully provided by another retail public utility without first obtaining a CCN that includes the area in which the consuming facility is located.
(b) A district may not provide services within the certificated service area of a retail public utility or within the boundaries of another district without the retail public utility's or district's consent, unless the district has a CCN to provide retail water or sewer utility service to that area.
(c) Except as otherwise provided by this subchapter, a retail public utility may not provide retail water or sewer utility service within the boundaries of a district that provides the same type of retail water or sewer utility service without the district's consent, unless the retail public utility has a CCN to provide retail water or sewer utility service to that area.
(d) A person that is not a retail public utility, a utility, or a water supply or sewer service corporation that is operating under provisions in accordance with TWC §13.242(c) may not construct facilities to provide retail water or sewer utility service to more than one service connection that is not on the property owned by the person and that is within the certificated service area of a retail public utility without first obtaining written consent from the retail public utility.
(e) A supplier of wholesale water or sewer service may not require a purchaser to obtain a CCN if the purchaser is not otherwise required by this chapter to obtain a CCN.
