1 <br /> ORANGE COUNTY <br /> NORTH CAROLINA <br /> MEMORANDUM <br /> TO: Board of County Commissioners <br /> Bonnie Hammersley, Orange County Manager <br /> Travis Myren, Orange County Deputy Manager <br /> CC: Quintana Stewart, Orange County Health Director <br /> Victoria Hudson, Orange County Environmental Health Director <br /> Michael Rettie, Orange County Chief Building Official <br /> FROM: Craig N. Benedict, Orange County Planning Director <br /> DATE: February 19, 2019 <br /> SUBJECT: BOCC Information Item- Greywater and/or Reclaimed Water <br /> Systems <br /> An inquiry was posed at the BOCC of December 2018 regarding OWASA's `greywater' <br /> system. The nomenclature of `greywater' often can be confused with other non-potable <br /> water such as `reclaimed water systems'. OWASA's system is in this latter category. <br /> Attachment 1 is a 2 page explanation regarding their reclaimed water system. <br /> This reclaimed water system (RWS) uses a byproduct of advanced treatment of waste <br /> water from their sewer treatment plant. There are other water conservation measures such <br /> as `rainwater harvesting' that relate more closely to `greywater' wherein OWASA <br /> recognizes that private individuals may collect rainwater and discharge the flow (in part) to <br /> the wastewater stream (i.e. unmetered non-potable water). OWASA has a resolution <br /> (attachment 2) that addresses this related policy. <br /> To round out the use and application of `greywater' or `reclaimed' water system, I have <br /> attached a joint memo from the Building Division and Environmental Health which <br /> addresses how the implementation and implication of such systems are addressed by the <br /> state regulatory codes (Attachment 3). <br /> Attachments: <br /> 1. Attch 1- OWASA explanation regarding their reclaimed water system <br /> 2. Attch 2- OWASA resolution for rainwater harvesting systems <br /> 3. Attch 3- Joint Memo from Building and Environmental Health <br />
