{¡;7Á Reclaimed water will be taken from the Photo * Peri Water Treatment System full scale pilot until remodeling of the San Marcos Wastewater Treatment Plant is completed for the ne\-v permit of 5-5-2-1. At that time, reclaimed water needed to meet acute drought conditions will be taken near the effluent discharge point. The reclaimed water will be treated by the Photo * Peri Water Treatment System and disinfected through a system to a level that does not exceed a BOD5, turbidity, or fecal coliform count previously described in the above paragraph. The Photo * Peri Water Treatment System has been in a full scale pilot testing mode for over two years. Data on the system has been collected on a weekly or biweekly basis since August of 1994. The system has been operated under -- various conditions and rates to establish its working parameters. Specific treatment capacity is available through adding modules to the system through additional manifolding. The CUITent system takes wastewater from the final clarifier and goes through the pilot system's tanks and through the treatment process before being returned to the [mal clarifier. Our proposal consist of rerouting some of the water from the tanks to tanker trucks and to the site for distribution or to short term storage of the reclaimed water prior to use. As you may know, the City of San Marcos has pending before the Texas Natural Resource Conservation Commission Application No. 5539 to Convey Private Water Via a Watercourse which would allow reuse of the City's entire wastewater discharge through a new surface water treatment plant. The City's use of reclaimed water as described in this letter would cease if that . permit is granted, upon completion of the surface water treatment plant project. OPERATION AND MAINTENANCE PLAN The Photo * Peri Water Treatment System will be tested on a weekly schedule to comply ,'lith the TNRCC regulations. During obvious upset conditions at the San Marcos Wastewater Treatment Plant, the wastewater will not be diverted for reclaim use to ensure the quality of the reclaimed water. Weare not providing a copy of a signed contract betWeen the user and the provider since both are the City of San Marcos. All storage facilities will be clearly labeled with signs stating that the water inside the tanks is reclaimed water and not for potabl~ use. Tanker trucks and trucks hauling the reclaimed water will be labeled as such. Areas where the reclaimed water will be used will have signs for the public stating that reclaimed water is being used for irrigation purposes. In order to prevent the contamination of the potable water system, all irrigations systems that are cUITently on a potable water system will not be used for reçlaimed water. Separate facilities will be provided. All storage facilities that are not within a protected area will have locks or locking devices or removable handles to prevent unauthorized use ofthe reclaimed ,vater.
