Section VII-525 - Reclaimed Waterdf

A. Potable water utilized for heat exchangers or compressors on a Grade A dairy farm may be salvaged and used for certain limited applications in the milking operation on the dairy farm if the following criteria are met:

1. The reclaimed water_df piping system shall meet the requirements of Parts XII and XIV of this Code.

2. Any re-circulated cold reclaimed water_df which is used in exchangers, including systems in which a freezing point depressant is used, shall be from a safe source and protected from contamination. Such reclaimed water_df shall be tested at the minimum frequencies specified in this Section and shall otherwise comply with any other requirements of this Section. Freezing point depressants shall be non-toxic.

3. The reclaimed water_df shall be stored in a storage vessel properly constructed of such material that will not contaminate the reclaimed water_df system and will protect the system from possible contamination.

4. The storage vessel shall be equipped with a drain and access point to allow for cleaning.

5. No cross-connection shall exist between the reclaimed water_df supply and any unsafe or questionable water supply or any other source of pollution. No cross connection shall exist between any potable water supply or potable water distribution system and the reclaimed water_df system.

6. There are no submerged inlets through which the reclaimed water_df system may be contaminated.

7. The reclaimed water_df shall be of satisfactory organoleptic quality and shall have no off flavors or odors.

8. The reclaimed water_df shall comply with the bacteriological standards of Appendix G, Section I of the PMO.

9. Samples of the reclaimed water_df shall be collected and analyzed prior to initial approval and semi-annually thereafter.

10. Approved chemicals, such as chlorine, with a suitable retention period, may be used to suppress the development of bacterial growth and prevent the development of tastes and odors in the reclaimed water_df.

11. When chemicals are added to the reclaimed water_df, a monitoring program for such added chemicals shall be in effect and such chemicals shall not add substances that will prove deleterious to the use of the reclaimed water_df or contribute to product contamination.

12. If the reclaimed water_df is to be used for the sanitizing of teats or equipment (back-flush systems), approved sanitizers, such as iodine may be added by an automatic proportioning device located downstream from the storage vessel but prior to its end-use application. An approved backflow prevention device shall be installed immediately upstream of the point of chemical addition.

B. Reclaimed water_df from the current milking, obtained directly from the discharge of a raw milk heat exchanger or compressor into the wash vat or utensil sink, may be used in the following applications:

1. the one time pre-rinsing of milking equipment, including milk lines, milking claw assembly, milk receiver, etc., and then discharged to waste; or,

2. for non-potable purposes approved by the state health officer, e.g., use as a non-potable water source when the intended use does not require the use of potable water.
