Cross connections with potable water mains prohibited.
San Antonio City Code § 34-1185
in effectSec. 34-1185. - Cross connections with potable water mains prohibited.
(a) It shall be unlawful for any person to make or to maintain any cross connection or to allow any cross connection to exist at any place under the control of any person.
(b) The term "cross connection," as used in this section, is any mechanical union or any hydraulic union which, under any condition, might pass recycled water into the potable water supply system. Any switchover system potentially allowing use of potable water as a temporary substitute for recycled water if recycled water is not available shall be built to ensure that recycled water does not back flow into the potable water system.
(c) To ensure the complete separation of a customer's onsite potable water system from the lines supplying recycled water, SAWS will require an inspection of the customer's onsite potable water system by the local plumbing inspection department having jurisdiction prior to supplying recycled water. Facilities located outside incorporated city limits and not having access to municipal plumbing inspections, shall have the inspection conducted by a state licensed water protection specialist or a TNRCC approved customer service inspector. The SAWS backflow prevention section shall be notified of and participate in the inspections. The inspections will involve procedures to be established by SAWS. The inspections and any recommended piping modifications shall be completed prior to commencement of the recycled water service. A reinspection shall be conducted every three (3) years or as deemed necessary by the local plumbing inspection department and/or SAWS.
