The project includes improvements at the Oso Water Reclamation Plant (WRP) and the installation of a reclaimed water transmission main connecting the Oso facility with the Greenwood Wastewater Treatment Plant. The work also includes street improvements, including milling and overlaying, as well as the removal and replacement of sidewalks and ADA ramps where required to accommodate pipeline construction.
The project is the second phase of a two-part initiative to expand reclaimed water use in Corpus Christi. The first phase, a design contract valued at up to $11 million, was awarded to Ardurra Group Inc. and approved by Corpus Christi City Council on November 18, 2025.

On June 30, 2026, the council approved the construction phase through an emergency contracting process, awarding a $107.5 million contract to Reytec Construction Resources Inc., a Houston-based contractor, according to city announcements. The contract represents the main construction package within the wider $108 million project estimated in the TDLR filing.
According to city officials, the transmission corridor will be constructed through four pipeline segments that can progress simultaneously, allowing multiple crews to work at the same time. The project also includes a separate work package for a new pump station and wet well at the Oso plant.
Once complete, the project is expected to increase available reclaimed water supply by 11 million gallons per day, bringing the city’s total non-potable reuse capacity to approximately 16 million gallons per day.
The reclaimed water will support major industrial users and help reduce pressure on Corpus Christi’s potable water supplies. The city has already established a recycled water agreement with Valero’s Corpus Christi refinery and has reused treated effluent for non-potable applications, including irrigation of parks and golf courses, since the 1960s.
Despite its long history of water reuse, Corpus Christi has identified additional opportunities to increase the use of treated wastewater. City officials have said that only a limited share of the effluent produced by the city’s water reclamation plants has historically been reused.
The new pipeline is intended to expand that capacity by providing a reliable alternative water source for industrial demand, helping preserve freshwater supplies for other users as the region faces increasing water challenges.
Corpus Christi Water supplies communities across seven counties in South Texas and has pursued several measures in recent years to diversify its water resources amid prolonged drought conditions. The city accelerated the reclaimed water project after concerns that drought conditions could push the Coastal Bend region toward a Level 1 water emergency as early as September 2026.
Rainfall from storms affecting the region in July 2026 eased those immediate concerns, and city officials now estimate that a potential Level 1 water emergency would not occur until around fall 2028. However, water supply resilience remains a priority as population growth and industrial demand continue to place pressure on regional resources.
