Brushy Creek Regional Wastewater Treatment System East Plant - 40 MGD Expansion - Environmental Information Document

The City of Round Rock, in partnership with the Brushy Creek Regional Wastewater System (BCRWWS)—which includes the Cities of Round Rock, Austin, Cedar Park, and Leander—is soliciting public review and comment on an Environmental Information Document (EID) for the expansion of the Brushy Creek East Wastewater Treatment Plant from 30 Million Gallons per Day (MGD) to 40 MGD capacity. This procurement addresses infrastructure expansion necessary to meet mandatory planning requirements under Texas Administrative Code 305.126, as the existing facility is projected to reach 90 percent of its permitted average daily flow by 2027 and must accommodate an anticipated 2040 population of 216,956 residents. The project scope includes construction of a fourth treatment train and capacity upgrades encompassing biological nutrient removal, tertiary filtration, ultraviolet disinfection, and enhanced solids handling systems at the existing 29.73-acre facility located at 3939 E Palm Valley Boulevard in Round Rock, Williamson County, Texas. Construction is scheduled to commence in mid-2027 and conclude by September 2030, with environmental review completion anticipated by March 2026 and design completion and permitting also targeted for March 2026. Written comments on the proposed project must be submitted by May 27, 2026, to 3400 Sunrise Rd, Round Rock, TX 78665, Attention: Ms. Rebecca Vento, or to the Texas Water Development Board, with additional public notice information available at https://www.roundrocktexas.gov/city-services/public-notices/. Environmental analysis has determined no significant adverse impacts to wetlands, streams, waters of the United States, threatened and endangered species habitat, prime farmland, cultural resources, or hazardous materials, with design features including elevated critical infrastructure and hydraulically isolated treatment trains to address 100-year floodplain considerations.

The total estimated project cost is $117,570,000, with the City of Round Rock applying for approximately $60 million in funding through the Texas Water Development Board's (TWDB) Clean Water State Revolving Fund (CWSRF), with remaining costs financed through local cash contributions or open market financing. The document does not specify set-aside designations, disadvantaged enterprise restrictions, or incumbent vendor preferences; however, the procurement process indicates that federal, state, and local agency coordination has been completed, with positive responses from the City Floodplain Administrator, USDA Natural Resources Conservation Service, and Texas Historical Commission confirming project feasibility as designed. The expansion will occur on previously disturbed land within the existing operational facility, which represents established infrastructure that any contractor must integrate with and accommodate during the construction phases. Prospective respondents and interested parties are encouraged to review the complete Environmental Information Document to understand the technical specifications, environmental findings, and project requirements. Organizations responding to related procurement opportunities should be prepared to demonstrate experience with large-scale wastewater treatment plant expansions, compliance with state and federal environmental regulations, and the capability to manage complex construction projects requiring coordination with multiple municipal entities and regulatory agencies.
