  1. MOLZEN-CORBIN & Associates Wastewater Effluent Reuse –Irrigation Relief in the High DesertCity of Albuquerque, NMbyJames Chavez, PE, City of AlbuquerqueBob Paulette, PE, Wilson & CompanyRon Mosher, PE, Molzen-Corbin & Associatespresented to the Rocky Mountain Section WEA/AWWA Annual Conference, Casper WyomingSeptember 17, 2003

  2. 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)

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

  6. Reuse Quality Guidelines

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

  8. Overall Reuse Polishing Layout

  9. Filtration Screening Study • Conventional Deep Bed Coarse Media • Automatic Backwash Traveling Bridge • Cloth Filters • Disk Filters • Membrane Filtration • “Fuzzy” Filters

  10. 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

  11. Pipeline Alignment Map

  12. 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

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

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

  15. Pipeline Installation – Residential Areas • Residential “Issues” • Traffic Control • Residential Access • “Good Neighbor”
