Member Nejedly agreed that the demand for recycled water is still high, but stated that it should be free without limitations. Chair Causey agreed with Member Nejedly that the District is not making much profit by charging commercial customers, but also questioned if demand would remain constant. Member Nejedly believed that commercial customers will always have a need for recycled water, especially if at no cost and it is easily available (without the use of a meter). Mr. Lopez stated that the Position Paper is scheduled to be presented at the November 5, 2015 Board meeting and may include a resolution for the change order work proposed. COMMITTEE ACTION: Recommended Board approval of automated commercial recycled water truck fill station on a pilot basis.
