Water - As introduced, prohibits the department of environment and conservation from prohibiting a utility that provides drinking water from pumping or otherwise withdrawing water from natural waters for purposes of providing drinking water, including as a prerequisite to renewal of the utility's permit, unless the prohibition is required to comply with federal law. - Amends TCA Title 4; Title 68, Chapter 221 and Title 69.

SB 1750 prevents Tennessee's Department of Environment and Conservation from blocking public water utilities (like city or county water systems) from pumping or withdrawing water from natural sources for drinking water, unless federal law specifically requires it. The bill allows the department to prohibit such water use only if mandated by federal laws like the Safe Drinking Water Act or Endangered Species Act, and requires them to provide written notice citing the exact federal law. This directly affects water utilities and the state department by limiting the department's authority to restrict water access for drinking water services. The law takes effect July 1, 2026, and applies to permit renewals and ongoing operations.
