Senate Bill 4, introduced in Indiana on April 2, 2025, aims to regulate the transfer of water resources across state basins, addressing growing concerns over water management and sustainability. The bill mandates that any entity transferring, selling, or leasing a long-haul water pipeline must notify the Indiana Utility Regulatory Commission (IURC) within 60 days of finalizing the transaction.

Key provisions of the bill include restrictions on transferring water out of a basin if the amount exceeds an annual average of 30 million gallons per day or if the water is sourced from a restricted use area. Additionally, the bill requires a transfer permit from the Department of Natural Resources (DNR) for any existing or ongoing interbasin transfers that exceed the capacity of the involved systems over a 90-day period. The DNR will approve permits only if the transfer does not lead to groundwater overdraft or stream flow depletion and is deemed in the public interest.

The legislation has sparked notable debates among stakeholders. Proponents argue that the bill is essential for protecting Indiana's water resources amid increasing demand and environmental concerns. Critics, however, express worries about the potential bureaucratic hurdles it may create for businesses and agricultural operations reliant on water transfers.

The implications of Senate Bill 4 are significant, as it seeks to balance economic interests with environmental sustainability. Experts suggest that the bill could lead to stricter oversight of water resources, potentially impacting industries that depend on large-scale water usage. As the bill progresses through the legislative process, its final form and the extent of its enforcement will be closely monitored by both supporters and opponents.

In conclusion, Senate Bill 4 represents a critical step in Indiana's approach to water resource management, aiming to ensure that water transfers are conducted responsibly while safeguarding the state's natural resources for future generations.
