  1. Aquatic Filter Barrier Technology and the Marine Life Exclusion System Application for Kensico Reservoir

  2. Kensico Reservoir Application Kensico Marine Life Exclusion System Catskill Upper Effluent Chamber (UEC)

  3. Kensico Reservoir Application Kensico Marine Life Exclusion System Requiring 1,000 MGD, the Catskill UEC intake in the Kensico Reservoir is a good match for the curtain-style MLES with the type of environment and water body available at the site.

  4. Kensico MLES Preliminary System • Preliminary Concept - Design Basis • 1,000 MGD maximum instantaneous flow rate • Fabric AOS of 0.5 mm (may be larger if acceptable) • Flux of 7.5 gpm/sf of fabric • Average depth of 40 vertical feet • Length may be approximately 2,300 lf • Fabric composite to include non-woven and woven • AirBurst™ cleaning system with redundant supply and automatic controls • Control System, includes remote monitoring and operation capability • Preliminary ballpark cost range - $1.75 – 3.5M

  5. Kensico MLES – Key Design Aspects • Key Design Factors/Considerations • Size of organisms to exclude • May affect design flow rate and therefore size • Non-intake flow and currents in vicinity of alignment • Bottom conditions for anchoring system • Loading, buoyancy, anchoring and load on curtain • Restrictions on bypass – any seasonal considerations • End terminations • Ambient aquatic flora

  6. Kensico Reservoir Application Kensico Marine Life Exclusion System 2,300 Foot Curtain – Representative Possible Alignment

  7. Kensico MLES Next Steps • Gunderboom Phase 1, Preliminary Conceptual Design and Feasibility Study includes: • Review of Site Information, Design Requirements • Development of Design Concept or Concepts • Determination of Additional Engineering Data Requirements • Development of Project Task Sequence and Estimated Budgets • Phase 1 estimated range – $25-40 K plus site visits and meetings

  8. Kensico MLES – Key Benefits • Proven results • No downtime for maintenance activities • Passive, automatic operation with monitored parameters; remote access available • Unit-based design • Results in easier adjustment of design length, straightforward component repair or replacement, and ability to proactively maintain • Environment less demanding overall than for other systems • Less wear & tear • Exclusion monitoring more straightforward • Experience with systems in more challenging environments suggests that this calmer environment will yield a longer system life span.
