Indirect/Direct Potable Reuse Feasibility Study

The City of Kyle, located south of Austin, is experiencing rapid population growth with an estimated 70,000 residents by the end of 2025. The city manages a public water system supplying about 21,000 connections with a firm capacity of 5.82 million gallons per day (MGD), sourcing water from its five wells, Canyon Lake via GBRA, and the Carrizo Wilcox aquifer through ARWA. In addition to water supply, Kyle operates a wastewater treatment plant with a current capacity of 4.5 MGD, expandable to 12 MGD, discharging treated effluent into the Bunton branch of Plum Creek. As the plant scales up, more stringent effluent treatment is required, including phosphorus reduction. The city currently uses type II reclaimed water for irrigation at the Plum Creek Golf Course and intends to upgrade to tertiary treatment for higher quality type I reuse, also expanding their non-potable reuse system. Kyle is pursuing an innovative approach to water sustainability through the implementation of an Indirect Potable Reuse (IPR) and Direct Potable Reuse (DPR) project, aiming to treat and recycle wastewater effluent as potable water for distribution within its public water system. The City of Kyle has issued a solicitation (RFQ-2026-051) for a feasibility study on this IPR/DPR project, seeking expert evaluation on the technical and operational viability of such water reuse initiatives. The procurement process is managed by the Water Utilities agency, with Daniel Dellemonache as the primary contact. This initiative reflects the city's leadership in sustainability and long-term water resource management, addressing future water demand and environmental considerations.
