The central Indiana region will need to withdraw almost 30 percent more water 50 years from now than it does today. That’s according to the first of several reports from the Indiana Finance Authority on the region’s water needs.
Half of that water will be needed for public drinking water supplies in Indianapolis and the nine counties that surround it.
“The suburban areas have grown very rapidly. The urban areas are more stable, relatively speaking in terms of population. So there's been this ring of growth that surrounds the city," said Jack Wittman, vice president of INTERA Geoscience & Engineering Solutions.
The IFA said the demand for water for businesses and agriculture is expected to go up too.
Since the early 2000s, water use for energy in the area has gone down dramatically due to coal plants shutting down.
We don’t know yet if there is enough water supply in central Indiana to meet that demand — the IFA is working on that report right now. Wittman said Indiana doesn’t have the water supply issues that you see in other parts of the country.
"It’s not really, 'Is it there?' as much as, 'Are we going to take care of it?'" he said.
The Finance Authority hopes to have a water plan for the central Indiana region by the end of this year.
Indiana Environmental reporting is supported by the Environmental Resilience Institute, an Indiana University Grand Challenge project developing Indiana-specific projections and informed responses to problems of environmental change.
