Additional Backup Information: The Hornsby Bend Biosolids Management Plant and Bird Observatory is located on a 1200-acre site that stretches along 3.5 miles of the Colorado River, approximately eight miles east of downtown Austin. The plant has grown into a nationally recognized and award-winning biosolids recycling facility and previously the recipient of a first-place award by the U.S. Environmental Protection Agency (EPA) for its recycling program. The plant was established in the 1950’s and receives and treats biosolids generated by Austin’s two regional wastewater treatment plants. The treatment process includes thickening, anerobic digestion, dewatering, composting, effluent ponds, and on-site irrigation. The treated sludge is recycled into a stable organic product marketed under the trade name Dillo Dirt™ that can be used safely as a fertilizer for City park facilities and sold to the public as an EPA-certified soil conditioner. Hornsby Bend Biosolids Management Plant is a non-discharge facility, which does not discharge into waters of the US, per Texas Commission on Environmental Quality permit. Currently, a Side Stream Treatment Plant and pond system treat ammonia and nitrogen resulting from the treatment main process. The Ammonia Removal Facility will provide enhanced ammonia and nitrogen treatment to significantly reduce the ammonia and nitrogen levels being treated by the pond system.  Item 10 Water & Wastewater Commission: November 10, 2026 Council: November 19, 2026 This item includes five allowances: • An allowance of $6,072,526 will be used to address provision of a complete De-ammonification System. • An allowance of $59,500 will be used to address provision of a complete Vertical-shaft Hyperbolic Mixer. • An allowance of $50,000 will be used to address contaminated soil or groundwater that is unexpectedly encountered during construction. • An allowance of $150,000 will be used to address rip rap to reinforce the pond berm. • An allowance of $83,000 will be used to address security upgrades. An allowance is an amount that is specified and included in the construction contract or specifications for a certain item(s) of work when details are not determined at the time of bidding. Due to the potential for unforeseen conditions during construction, a 10% contingency in funding has been included to allow for the expeditious processing of any change orders to cover any unforeseen construction costs associated with the project. There will be no impact to the public as all work will be done on City property that is closed to the public. If Council does not approve this item, ammonia and nitrogen levels would continue to be treated solely by the existing pond system, which may not achieve the desired environmental outcomes. The contract allows 660 calendar days for completion of this project. This project is located within zip code 78725 (District 2), within the City’s Extraterritorial Jurisdiction. City of Austin Council Meeting Backup: November 19, 2026 MWBE Summary Compliance Plan Verification File ID: 26-2953 PROJECT GOALS OR SUBGOALS MBE (use only if MBE/WBE goal) AFRICAN AMERICAN HISPANIC AMERICAN NATIVE/ASIAN AMERICAN WBE 0.00% 0.72% 2.81% 0.25% 1.62% MET MET MET MET Bidder: Sol#: Project Name: Hornsby Bend BMP Process Ammonia Removal Facility and Drainage Improv Matous Construction, Ltd.
