Paper Outline
  • Introduction
  • Development of Effluent Reuse Users
  • New NMED Reuse Discharge Guidelines
  • Effluent Polishing Treatment
  • Reuse Pipeline
  • Conclusions

3
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

4
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
  • Finalized August 7, 2003
  • Classes of Reuse - IA, IB, 2, 3
  • Sets Performance Limitations
  • More Flexibility in Facilities

Reuse Quality Guidelines
Class Parameter 30-Day Avg Maximum
Class 1A BOD5 10 15
Turbidity 3 NTU 5 NTU
Fecal Coliform 5 per 100 ml 23 per 100 ml
Class 1B BOD5 30 mg/l 45 mg/l
TSS 30 mg/l 45 mg/l
Fecal Coliform 100 per 100 ml 200 per 100 ml
Class 2 BOD5 30 mg/l 45 mg/l
TSS 30 mg/l 45 mg/l
Fecal Coliform 200 per 100 ml 400 per 100 ml
Class 3 BOD5 30 mg/l 45 mg/l
TSS 75 mg/l 90 mg/l
Fecal Coliform 1,000 per 100 ml 5,000 per 100 ml

Effluent Polishing Treatment
  • Low Lift Pumping from Chlorine Contact Chamber
  • Filtration
  • Disinfection
  • Clearwell
  • High Lift Pumping

9
Overall Reuse Polishing Layout
10
Filtration Screening Study
  • Conventional Deep Bed Coarse Media
  • Automatic Backwash Traveling Bridge
  • Cloth Filters
  • Disk Filters
  • Membrane Filtration
  • Fuzzy Filters

11
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

12
Pipeline Alignment Map
13
Mid-Point Storage Pump
  • Puerto Del Sol Golf Course
  • 1.9 million gallon Storage Tank
  • 560 gpm Pumping Station
  • Height Constraints FAA Esthetics
  • Location Constraints Golfers Neighborhood
  • Pipeline Location Along Fairway

14
Mesa Del Sol Recreation Area
  • New Roadway Not Built
  • Follow Proposed Right-of-Way
  • 40-50 Foot Cut/Fill

15
Pipeline Constraints Non-Residential Areas
  • Within Existing R/W
  • Utility Conflict Potential
  • Permitting Issues
  • MRGCD
  • AMAFCA
  • BNSF
  • NMDOT

16
Pipeline Installation Residential Areas
  • Residential Issues
  • Traffic Control
  • Residential Access
  • Good Neighbor
