Miami Dade Inflow/Infiltration Reduction Program

Client: Miami-Dade Water and Sewer
Location: Miami, FL

For the Miami Dade Inflow/Infiltration Reduction Program, Hazen and Sawyer managed short- and long-range budgets, prioritized needed improvements, administered construction contracts, evaluated change orders, and monitored payment requests and invoices. The result was the delivery of a $230 million program at a cost that was $4.1 million below the original budget.

Hazen and Sawyer served as Project Manager for the $230 million Miami Inflow/Infiltration Reduction Program, which was so successful it is now considered by EPA as a model for other programs.

Part of the program entailed comprehensive design and construction services for over 39,000 required sewer repairs.

We coordinated the smoke testing, manhole inspection and TV inspection of the entire system.

To address public concerns and foster acceptance by the local community, we organized outreach meetings and issued informational materials to residents.

The successful program reduced I/I by 100 mgd.
