The Indianapolis Airport Authority (IAA) has received four responses in connection with its request for qualification (RFQ) to carry out a stormwater and wastewater PPP project at the international airport.

In the coming weeks, the authority's selection committee will complete a thorough review of each of the responses. Further details has not been disclosed.

The airport's stormwater/wastewater systems are sufficient for the current volume of storm water activity but have limited capacity for new development. Within the next 10 years, the IAA anticipates substantial growth in its airside operations, which will have a significant impact on the airport's systems.

The IAA seeks partners who will bring state-of-the-art thinking to the glycol management and disposal process and propose cost-effective and sustainable capital improvements to the airport's systems. The ideal partner will be able to supply operations, maintenance, repair, replacement and administration services for the systems while providing for their long-term expansion.

The IAA owns and operates Indiana's largest airport system. In addition to the Indianapolis International Airport, its facilities include the Downtown Heliport, Eagle Creek Airpark, Hendricks County Airport, Indianapolis Regional Airport and Metropolitan Airport.
