When water is distributed by tank truck or trailer, in lieu of distribution piping, it must be accomplished in accordance with the requirements of this section.
- (1) The water shall be obtained from an approved source.
(2) The equipment used to haul the water must be constructed as follows.
- (A) The tank truck, or trailer, shall be used for transporting drinking water only, and shall be labeled "Drinking Water". Tanks which have been used previously for any other purpose shall not be used for hauling drinking water.
- (B) The tank shall be water-tight and of an approved material which is impervious and easily cleaned and disinfected. Any paint or coating and any plastic or fiberglass materials used as contact surfaces must be approved by the United States Environmental Protection Agency, the United States Food and Drug Administration, the United States Public Health Service, or the National Sanitation Foundation.
- (C) The tank shall have a manhole and a manhole cover which overlaps the raised manhole opening by a minimum of two inches and terminates in a downward direction. The cover shall fit firmly on the manhole opening and shall be kept locked.
- (D) The tank shall have a vent which is located and faced downward so as to minimize the drawing of contaminants into the stored water. The vent must be screened with 16-mesh or finer corrosion resistant material.
- (E) Connections for filling and emptying the tank shall be properly protected to prevent the possible entrance of contamination. These openings must be provided with caps and keeper chains.
- (F) A drain shall be provided which will completely empty the tank for cleaning or repairs.
- (G) When a pump is used to transfer the water from the tank, the pump shall be permanently mounted with a permanent connection to the tank. The discharge side of the pump shall be properly protected between uses by a protective cap and keeper chain.
- (H) Hoses used for the transfer of drinking water to and from the tank shall be used only for that purpose and labeled for drinking water only. The hoses shall conform to American National Standards Institute/National Sanitation Foundation (ANSI/NSF) Standard 61 and must be certified by an entity recognized by the Texas Natural Resource Conservation Commission (TNRCC).
(3) The water hauler shall perform the following operational procedures.
- (A) Hoses used for the transfer of drinking water to and from the tank shall be used only for that purpose and labeled for drinking water. The hoses must be properly stored between uses and must be provided with caps and keeper chains or have the ends connected together. Hoses and related appurtenances must be cleaned and disinfected on a daily basis or before start-up during intermittent use.
- (B) The tank shall be disinfected a minimum of once per month and at any time that contamination is suspected, and shall keep records of all tank disinfections or cleanings.
- (C) At least two samples of water must be submitted for bacteriological analysis, to a laboratory acceptable to the Texas Department of Health, for each month of operation.
- (D) A minimum chlorine residual of 0.5 mg/l must be maintained in the water being hauled. Chlorine or chlorine containing compounds may be added on a "batch" basis to maintain the required residual.
- (E) Operational records must be maintained detailing the amount of water hauled and purchased, and the source of water.
- (4) A person, firm, or corporation shall test and record the chlorine residual in the tank at the time of receipt. The record shall be maintained on file at the receiving location (bottle production plant) for a minimum of two years.
