Chairman Wheeler asked why putting reuse water into retention ponds was a bad <br />idea. Director Olson explained that all of the County's wastewater is converted to reuse (purple <br />pipe) and most of that water, in the past, had gone to golf courses; however, that process is being <br />transitioned to pressurized reuse lines. He said reuse water is disinfected and clean, but because <br />nutrients, nitrogen, and phosphorous are in the reuse water, these elements would eventually <br />transition into the ground water system. <br />Bob Adair, Chairman of the Agriculture Advisory Committee, said that the <br />recommendations presented had merit. He encouraged the Board to be proactive and move <br />forward with an alternative water supply. He also encouraged the Board to look at the diversity <br />of water supplies and felt the reuse water option should be considered as a water supply. Mr. <br />Adair recommended the County invest in a pressurized system instead of the passive low- <br />pressure system. He wanted to see reuse water be used for agricultural purposes as it becomes <br />available. Mr. Adair said he would like to see the County fund a mobile irrigation laboratory <br />through the Soil and Water Conservation District (SWCD) and the Water Management District, <br />and to have trained personnel go into the urban areas and make sure people's systems are <br />operating properly. He wanted to know about the status of the Treasure Coast Model and when <br />the plan was due. <br />Rich Burkley, SJRWMD, informed Mr. Adair and the Board that the model would <br />be a numerical model capable of looking at the cumulative and regional impacts. Currently the <br />districts are in the process of gathering data and developing the model; he anticipated the model <br />to be completed in October 2007. He explained that this would be a public domain tool that <br />consultants could use to discern what the impacts would be. <br />Bob Adair wanted to know why the ability to expand the south water treatment <br />plant could not be done with another well and was curious why the County would not consider <br />putting wells there, as opposed to the north County well field.
