Miami-Dade Inflow/Infiltration Reduction Program

For this 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.

Establishing Industry Standards

The successful program reduced I/I by 100 mgd and is considered by EPA as a model for other programs.
