The Public Utilities Board recommends approval (5 - 0). STRATEGIC ALIGNMENT This action supports Key Focus Area: Enhance Infrastructure and Mobility. INFORMATION/BACKGROUND The City of Denton is experiencing significant development in the Clear Creek Basin, situated north of Loop 288, which is creating increased demand for additional wastewater collection and treatment infrastructure in the area. The City’s 2023 Wastewater Master Plan highlights two major projects to meet this demand: the Clear Creek Sewer Interceptor and the Clear Creek Water Reclamation Plant (CCWRP). The design of the sewer interceptor is being completed under a separate contract. Planning for a wastewater facility at this location has been underway for several decades. In 1998, the City completed the Wastewater Treatment Planning Report, which detailed a future need for a treatment solution within the basin. The property intended for the CCWRP was purchased by the Water Department in 2000. In 2002, a Preliminary Design Report was completed for a 0.95-million-gallon-per-day (MGD) facility, which supported the issuance of a partial discharge permit by the Texas Commission on Environmental Quality (TCEQ). By 2003, design efforts had reached approximately 85 percent completion before being paused due to changes in development patterns. In 2025, the site received a full TCEQ discharge permit authorizing a treatment capacity of 10 million gallons per day (MGD). The CCWRP will be located on City-owned property along Hartlee Field Road and is currently permitted for both lift station and treatment use. As the initial phase of this project, a lift station and force main will be constructed to convey upstream flows to the existing downstream conveyance system, and this facility will ultimately serve as the headworks for the CCWRP. Design consultants will focus on the Water Reclamation Plant, which will be delivered using the Construction Manager at Risk (CMAR) method. The facility is estimated to cost $455,000,000 to construct. City Hall 215 E. McKinney Street Denton, Texas www.cityofdenton.com To refine this estimate, an Engineer’s Opinion of Probable Construction Cost (OPCC) will be provided as part of the Preliminary Design Report (PDR) portion of this contract. The anticipated project timeline for design is May 2026 through December 2028, followed by construction from December 2028 through December 2032. This scope includes design and construction services for an advanced water reclamation plant with headworks that incorporate: • Headworks Systems - High‑efficiency screening and grit removal to protect downstream processes. • Biological Nutrient Removal (BNR) - Full Biological Nutrient Removal process for enhanced nutrient reduction. • Membrane Bioreactor (MBR) Treatment - Membrane Bioreactor treatment system producing high‑clarity, highly treated effluent. • Odor Control Systems - Integrated odor‑mitigation systems to reduce operational and community impacts. • Ultraviolet (UV) Disinfection - Ultraviolet disinfection for final pathogen removal. • Effluent Quality Standards - Final water meets or exceeds standards for reuse, environmental discharge, and livestock consumption. • Architectural Facility Components - Building and structural elements supporting the reclamation facility. To ensure the facility maintains a positive relationship with neighboring properties, the design will incorporate comprehensive odor-control systems and evaluate sound levels to determine whether noise- attenuation measures are necessary to minimize impacts on surrounding properties. The project scope also includes coordination to minimize impact on the existing mountain bike trail through stakeholder outreach and specialized trail design. Key Data Summary for Reference Category Detail Total Estimated Cost $455,000,000 Design Phase May 2026 – December 2028 Construction Services Phase December 2028 – December 2032 Site History Purchased Jan 2000; Permitted 2002 TCEQ Discharge Permit 10 MGD Discharge (Received 2025) Technology MBR + UV (Pathogen-free/High-quality effluent) The Water Utility Department is utilizing the approved RFQ 8213 Pre-Qualified List for Professional Engineering Services specializing in Water & Wastewater Infrastructure. The six pre-qualified firms for the project included: Carollo Engineers, Inc., Kimley-Horn and Associates, Inc., Freese and Nichols, Inc., RPS Infrastructure, Inc., Black & Veach Corporation, and CP&Y, Inc. Statement of qualification of the pre- qualified firms for the Water & Wastewater Infrastructure category were re-evaluated based on criteria including overall experience and qualification of the firm, past performance and relevant experience on similar projects, availability and experience of the proposed staff members. In-person interviews were conducted with the top three firms, with a six-member panel of three wastewater personnel, two water utility project managers, and one procurement representative. Based upon this evaluation, Carollo Engineers, Inc. ranked highest for its extensive experience in wastewater treatment and its recognized leadership in reuse projects, backed by decades of delivering reliable, high-performing treatment solutions. Their proven expertise and strong record with facilities of similar scope make them the clear choice for this effort. Request for Qualifications for an engineering services list for various water and wastewater utilities projects for the Water Utilities Department was solicited using the City’s formal solicitation process. City Council approved a pre-qualified list of professional service firms on March 5, 2024 (Ordinance 24-390). PRIOR ACTION/REVIEW (COUNCIL, BOARDS, COMMISSIONS) On March 5, 2024, City Council approved RFQ 8213 for a prequalified list of firms for engineering services for various water and wastewater utilities projects for the Water Utilities Department (Ordinance 24-390). On June 8, 2026, the Public Utilities Board (PUB) recommended this item to the City Council for consideration.
