16 Tex. Admin. Code § 24.205 - Adequacy of Water Utility Service

Sufficiency of service. Each retail public utility which provides water service shall plan, furnish, operate, and maintain production, treatment, storage, transmission, and distribution facilities of sufficient size and capacity to provide a continuous and adequate supply of water for all reasonable consumer uses.

(1) The water system quantity and quality requirements of the TCEQ shall be the minimum standards for determining the sufficiency of production, treatment, storage, transmission, and distribution facilities of water suppliers and the safety of the water supplied for household usage. Additional capacity shall be provided to meet the reasonable local demand characteristics of the service area, including reasonable quantities of water for outside usage and livestock.

(2) In cases of drought, periods of abnormally high usage, or extended reduction in ability to supply water due to equipment failure, to comply with a state agency or court order on conservation or other reasons identified in the utility's approved drought contingency plan required by 30 TAC § 288.20(relating to Drought Contingency Plans for Municipal Uses by Public Water Suppliers), restrictions may be instituted to limit water usage in accordance with the utility's approved drought contingency plan. For utilities, these temporary restrictions must be in accordance with an approved drought contingency plan. Unless specifically authorized by TCEQ, retail public utilities may not use water use restrictions in lieu of providing facilities which meet the minimum capacity requirements of 30 TAC Chapter 290 (relating to Public Drinking Water), or reasonable local demand characteristics during normal use periods, or when the system is not making all immediate and necessary efforts to repair or replace malfunctioning equipment.

(A) A utility must file a copy of its TCEQ-approved drought contingency plan with the utility's approved tariff. The utility may not implement mandatory water use restrictions without an approved drought contingency plan unless authorized by the TCEQ. If TCEQ provides such authorization, the utility must provide immediate notice to the commission.

(B) Temporary restrictions must be in accordance with the utility's approved drought contingency plan on file or specifically authorized by the TCEQ. The utility shall file a copy of any status report required to be filed with the TCEQ with the commission at the same time it is required to file the report with the TCEQ.

(C) The utility must provide written notice to each customer in accordance with the drought contingency plan prior to implementing the provisions of the plan. The utility must provide written notice to the commission prior to implementing the provisions of the plan.

(3) A retail public utility that possesses a certificate of public convenience and necessity that is required to file a planning report with the TCEQ under requirements in 30 TAC Chapter 290, Subchapter D (relating to Rules and Regulations for Public Water Systems) shall also file a copy of the planning report with the commission at the same time it is required to file the report with the TCEQ.

(A) If the TCEQ waives or limits the reporting requirements, the utility shall file with the commission within ten days a notice that the reporting requirements have been waived or limited, including a copy of any order or other authorization.

(B) A retail public utility shall file a copy of any updated or amended plan or report required to be filed under this section.

(C) Submission of this report shall not relieve the retail public utility from abiding by the requirements of other regulatory agencies as set forth in § 24.203 of this title (relating to Requirements by Others).

(4) Each retail public utility which possesses or is required to possess a certificate of convenience and necessity shall furnish safe water which meets TCEQ's minimum quality criteria for drinking water.

(5) Every retail public utility shall maintain its facilities to protect them from contamination, ensure efficient operation, and promptly repair leaks.
