Sustainable Infrastructure Design: Effective Solutions for Dreissenid Mussel Control

This publication explores a comprehensive systems approach for designing water treatment infrastructure to combat the invasion of zebra and quagga mussels. Drawing from European experiences, it covers intake design, pumping systems, internal water flow, and shoreline pumping bay specifications. Emphasis is placed on incorporating features like smooth walls, antifouling coatings, and cathodic protection to minimize mussel infestation. Access systems, offshore structures, and long-term planning considerations are also discussed for efficient maintenance and operation.

  1. Systems Approach for New Infrastructure Design Chuck O’Neill Sr. Extension Specialist NY Sea Grant / Cornell University PREPARING FOR THE INVASION Zebra and Quagga Mussels in Utah Water Treatment Facilities 15 July 2008 Orem, Utah

  2. Dreissenid Mussel Control – Systems Approach European Experience as a Guide • Intake design • Pumping & flow velocity • Onshore structures • Internal water flow • Trouble locations • Long-term design

  3. Dreissenid Mussel Control – Systems Approach • Single Short Intake • Piggable • Dewater with cleanout • Dual Short Intakes • Hermetically seal with cleanout • Alternate pumping schedule Shoreline Pumping Bay

  4. Systems Approach - Intake Specifications • Smooth Walls • Low friction coefficient • Maintain good laminar flow Trash Racks • Antifouling or fouling release coatings • Cathodic protection • Uninterrupted Flow • Wide radius turns • No major changes in diameter • Minimize vertical sections Access

  5. Systems Approach – Pumping & Flow Velocity • Maintain flow > 1.5 m/sec • Small vs. large diameter conduit • Maintain low friction coefficient • High vs. low velocity H2O flow

  6. Systems Approach – Offshore Structures • Wet Wells, Low Lifts, Pumphouses • High-velocity laminar water flow • Smaller volume structures • Eliminate eddying • Hard-to-Reach Locations • Air bubblers/curtains • Cathodic protection

  7. Systems Approach – Internal Water Flow • Circulating Water Systems • Maintain smooth, fast flow • Copper and polymer surfaces • Minimize eddying • Utilize waste heat - recirculate • Service Water Systems • Maintain smooth, fast flow • Copper and polymer surfaces • Backflushablemicro filtration Design in Cleanouts/Access

  8. Systems Approach – Long-term Approach • Design With Mussels in Mind • Over-design • Design cleanouts & access • Dewatering & Mussel Removal • Part of routine unit downtime
