City of San Marcos Chapter 210 of Title 30 Texas Administrative Code (T AC) USE OF RECLAIMED WATER OPER..A.TION AND MAINTENANCE PLAN (A) a labeling and separation plan for the prevention of cross connections between reclaimed water distribution lines and potable water lines; (a) All hose bibs and faucets shall be painted purple and designed to prevent connection to a standard water hose. Hose bibs shall be located in locked, below grade vaults which shall be clearly labeled as being of non-potable quality. As an alternative to the use of locked, below grade vaults with standard hose bibs services, hose bibs may be placed in a non-lockable service box which can only be operated by a special tool so long as the hose bib is clearly labeled as non-potable water, in accordance with subsection (b) of this section. (b) One of the following requirements must be met by the user or provider, for any area where reclaimed water is stored or where there exist hose bibs or faucets: (1) Signs having a minimum size of eight inches by eight inches shall be posted at all storage areas and on all hose bibs and faucets reading, in both English and Spanish, "Reclaimed Water, Do Not Drink" or similar warning. (2) The area shall be secured to prevent access by the public. (c) Reclaimed water piping shall be separated form potable water piping by a horizontal distance of at least nine feet. Where the nine foot separation distance cannot be achieved, the reclaimed water piping must meet the line separation requirements of Chapter 290 of this title (relating to Water Hygiene). (d) Where a reclaimed water line parallels a sewer line, the reclaimed water line shall be constructed in accordance with subsection (e) or (f) of this section. The horizontal separation distance shall be three feet (outside to outside) with the reclaimed water line at the level of or above the sewer line. Reclaimed water lines which parallel sewer lines may be placed in the same benched trench. Where a reclaimed water line crosses a sewer line, the requirements of S 290.44(e)(5)(B) of this title (relating to Location of Water Lines) shall be followed, with "reclaimed water line" substituted in S 290.44(e) of this title (relating to Location of Water Lines) for "water line." (e) Reclaimed water lines which transport reclaimed water under pressure shall be sized according to acceptable engineering practices for the needs of the reclaimed water users. The designer shall consider methods to prevent or maintain lines to mitigate the effect of
