The Beneficial Reuse Project

• As the water/wastewater costs rise, communities
  have started to look
• for different methods of water/wastewater
  disposal
• Communities are considering and implementing
  water reuse projects
• that reclaim valuable wastewater discharges,
  substituting for drinking
• water supplies in a wide variety of potable and
  industrial uses
• Sanitary sewer collection and treatment is
  provided by the University
• Area Joint Authority (UAJA) at its Spring Creek
  Pollution Control Facility
• (a 10.6 million-gallon-per-day advanced
  wastewater treatment plant
• that discharges to Spring Creek)
• Total project cost approximately 154 million
• To produce the reuse water, UAJA developed a
  multiple-barrier approach to produce an
  exceptional quality product while ensuring
  adequate safeguards to limit the potential for
  the production of a nonpotable product
• The process first goes through prescreening with
  a 500-micron wedge wire strainer
• Then the primary treatment is accomplished
  through microfiltration
• The microfiltration system was proven to provide
  the highest quality water with the lowest
  operating and maintenance costs
• The system incorporates backwash treatment to
  recover 99 of the product water for feed to the
  reverse osmosis system
• Following reverse osmosis, UAJA uses a two-step
  disinfection process for the final barrier
• They then store the reuse water for resale within
  its newly constructed distribution system
• Industries that use the reuse water
