  Wastewater Treatment/Water
       Recycling Center
• Evaluation of options
• Proposed technology
• Site evaluation/Community Advisory
  Committee
• Ongoing process
  – Open House
  – Environmental assessment


                                       2
 Why are we looking at wastewater
       treatment options?

• Existing FW system has 1 wastewater
  treatment plant (Village Creek WWTP)
• Growth occurring in the north, west, and
  southwest
  – Northern growth addressed by TRA’s Denton Creek
• Need to identify opportunities for beneficial
  reuse
  – Region C Plan calls for of 28% of future supply
    derived from conservation & reuse
                                                      3
       Background and History
• 1924 - first wastewater
  plant at Gateway park
  (old Riverside WWTP)




                            • 1958 – Village Creek
                              WWTP
                            • Original capacity - 5 mgd
                            • Current capacity - 166
                              mgd
                                                    4

Mary’s Creek Basin




                     6
                Growth Projections
• The Mary’s Creek
  basin has the most
  potential for
  development
• The basin is centrally
  located and near
  potential water reuse
  opportunities
• Preliminary
  Wastewater Master
  Plan identifies a need
  by 2025
   – regional development
     could impact schedule


                                     7
           Reuse Potential
• Numerous studies have identified potential to
  implement reuse in west Fort Worth
• Planned installation of dual systems for the
  distribution of reuse water
• Reuse is a sustainable practice
• Reuse delays the need for developing raw water
  supplies



                                               8
        What are the wastewater
          treatment options?
1. Allow growth on the west side until existing
   system capacity is met
2. Convey flow to Village Creek Wastewater
   Treatment Plant (VCWWTP)
3. Build wastewater facility on west side of Fort
   Worth
  •   Conventional Process
  •   High Tech Facility


                                                    9
Option 1 – Use existing capacity

 Pros                     Cons
 • No immediate impact    • Short term solution
   to neighboring areas   • Development would be
                            curtailed once capacity is
                            reached
                          • No opportunity for water
                            reuse




                                                     10
Option 2 - Convey flow
to Village Creek WWTP




                         11

    Option 2 – Convey flow to VCWWTP

Pros                                 Cons
•   Addresses treatment needs of     •   High capital & operational costs
    increased flows from west side   •   Negative impact of increased
    development                          transportation time
•   Limited initial impact to              – Increased environmental risk
    development in Mary’s Creek              from potential overflows
                                           – Increased odor and pipe
                                             corrosion as H2S levels
                                             increase
                                     •   Disruption of Central City through
                                         rerouting of pipelines
                                     •   Short-term solution due to limited
                                         capacity at VC
                                     •   Regulatory limits on discharge
                                     •   No potential for water reuse

                                                                      13

   Option 3 –Water Recycling Center
Pros                                  Cons
• Manage impact of growth               – Impact to
                                          neighboring areas
  in city limits and ETJ
  – Limits need for new pipeline
    corridors through central city
• Opportunity for reuse
  – Furthers progress toward State
    and Regional goals
  – Positive impact on Water Supply
    and Water Quality
• Meet long-term regional
  growth demands
  – Provides potential for regional
    service
                                                              16
         Proposed Technology
• Membrane BioReactor (MBR)
  – Uses conventional methods of preliminary solids removal
    and biological aeration
  – Eliminates the need for secondary clarifiers and a
    separate filtration system
  – Membranes perform the separation of the final effluent
    through filtration
• Benefits
  –   Smaller facility footprint
  –   Better process, air, noise and lighting control
  –   Higher quality of effluent
  –   Construction can conform to community livability
• Limitations
  – Potential increase in operational costs

The facility’s effluent discharges through
a constructed, natural-looking stream to
two effluent display ponds, which
together with landscape architectural
features and trails, create a campus-like
setting that provides a community
amenity.                                                                          18
