CP190  Zebra Mussel Problems in Water Intakes / Pipelines Water Treatment
Excessive growth of zebra mussels in raw water intakes and pipelines causes blockages, increasing pumping costs and reducing pumping capacity. This problem was identified during the 1980's and chlorination strategies were developed for control.

However, recent incidents have highlighted that the problem has returned, either because of changes in chlorination practices or because strains of zebra mussels resistant to chlorine have developed. This project will evaluate the current situation to identify and specify cost-effective strategies for preventing the problems associated with zebra mussel growth.

Benefits to Clients

Through the prevention of excessive zebra mussel growth:

  • Avoidance of blockage of raw water intakes and pipelines
  • Reduction in pumping costs for raw water.
