Funding supports planning, acquisition, design, and construction addressing aging infrastructure, system deficiencies, capacity, water quality, conservation, real or apparent water loss, and additional or more reliable supplies.
Eligible work may include upgrading or replacing facilities and interconnecting with neighboring providers to resolve drinking water deficiencies or Texas Commission on Environmental Quality (TCEQ) violations. Direct and indirect potable reuse may qualify, limited to tertiary treatment of wastewater effluent and downstream components conveying water for potable use. Water supply corporations may partner with universities or research organizations on planning directly supporting an eligible infrastructure project; standalone research or academic studies are not specifically identified as eligible activities.
