<br /> ( MGD ) . The plant has undergone three expansions since the initial construction . The current permitted
<br /> capacity is 8 . 57 MGD . Camp Dresser & McKee Inc . (CDM ) was authorized in December 7 , 1999 , under
<br /> Work Authorization No . 10 . to perform engineering services to evaluate membrane process optimization
<br /> on all four skids at the South County RO Plant. The CDM investigative report dated March 2001 reports
<br /> that the membranes at the South County RO Plant have decreased in performance since installation . It is
<br /> typical for membrane performance to diminish over time . The CDM Report also included a membrane
<br /> and piping replacement specification . On April 3 . 2001 , the Board of County Commissioners approved
<br /> staffs recommendation to proceed with a formal Request for Proposal (RFP ) for replacement of the
<br /> membranes at the South County RO Plant.
