Water and Sewer Infrastructure

General Issues: Age and Capacity

 Main breaks: O & M costs and damaged roadways  Insufficient fire flows: Property insurance and public safety  Sewer main flow restriction: Main cleaning cost and

reduced capacity

 Inflow/infiltration and cross connections: WWTP loading  Sewer backups  Flooding

Water and Sewer Infrastructure

General Benefits of Proposed Water and Sewer Changes

More reliable services
Reduced O&M costs
Improved public safety
Future growth of City

Specific Examples:

Reduced water main breaks and associated disruption
Reduced storm water flooding
Reduce sanitary sewer backups
Improved fire flows
