The Most Needed, the Most Unique, the Most SustainableThe Arizona Water Infrastructure Finance Authority (WIFA) is known to provide loans and grants for constructing water and wastewater infrastructure. What is not well known, though, is the wide variety of interesting projects WIFA has funded. Some of these projects were critically needed for public health protection in communities otherwise unable to afford them. Some projects solved unique or distinctive problems. Still others showcased WIFA's encouragement and funding of projects that incorporated state-of-the-art "green" technologies for water and energy efficiency and resource recovery. While WIFA keeps busy with traditional drinking water and wastewater infrastructure projects, they are also promoting new initiatives to fund stormwater and recharge projects.This presentation will describe how WIFA goes about its business and provide a behind the scenes look at the many fascinating projects that WIFA can fund.
