introduction
Introduction
  • Effluent Reuse Part of Overall Water Resources Management Plan
  • Two Non-Potable Reuse Projects
  • North – Saves 2,296 Ac-ft/yr
  • South – Saves 2,455 Ac-ft/yr
  • In range of water for 2,000 homes
  • EA & FONSI Complete 2001
effluent reuse users
Effluent Reuse “Users”
  • Existing Potable Water Users
  • Turf Irrigation
  • Cooling Water
  • Feasibility Analysis Identified Potential
  • Design Analysis Further Defined
    • Quantity, Quality
    • Connection Points, Pressure
    • Existing System Modifications Required (Drinking Fountains, etc)
nmed reuse guidelines
NMED Reuse Guidelines
  • Finalized August 7, 2003
  • Classes of Reuse - IA, IB, 2, 3
  • Sets Performance Limitations
  • More Flexibility in Facilities
effluent polishing treatment
Effluent Polishing Treatment
  • Low Lift Pumping from Chlorine Contact Chamber
  • Filtration
  • Disinfection
  • Clearwell
  • High Lift Pumping
filtration screening study
Filtration Screening Study
  • Conventional Deep Bed Coarse Media
  • Automatic Backwash Traveling Bridge
  • Cloth Filters
  • Disk Filters
  • Membrane Filtration
  • “Fuzzy” Filters
reuse pipeline
Reuse Pipeline
  • Alignment Set By Feasibility Study, EA & FONSI
  • All in Existing R/W
  • Locate within Corridors to Minimize Utility Conflicts
  • Crossing Permits – AMAFCA, MRGCD, BNSF, NMDOT
mid point storage pump
Mid-Point Storage & Pump
  • Puerto Del Sol Golf Course
