TO:Andrew P. Powers, City Manager
FROM:Nader Heydari, Public Works Director
DATE:February 10, 2026
SUBJECT: Hill Canyon Treatment Plant Screening Equipment Maintenance Agreement
RECOMMENDATION:
1. Approve sole source designation and agreement with Huber Technology, Inc. (Huber) (Denver, NC) for maintenance and repair services of Huber screening equipment in the amount not to exceed $172,568.25 for a period beginning February 10, 2026, and ending December 31, 2030.
2. Authorize expense in the amount of $20,666.70 in FY 2025-26 and $33,755.90 in FY 2026-27 from A/C #621-8250-682-5699 (Wastewater Contracted Services) for equipment maintenance and repair services.
3. Find that this action is not a project as defined under the California Environmental Quality Act.
LEVINE ACT ITEM: Yes
FINANCIAL IMPACT:
No Additional Funding Requested. $20,666.70 is included in the Adopted FY 2025-26 Wastewater Fund Budget and $33,755.90 is included in the Adopted FY 2026-27 Wastewater Fund Budget. Additional funds for the remaining contract term will be requested during the next biennial budget process (Wastewater Contracted Services).
BACKGROUND:
The City’s Hill Canyon Treatment Plant (HCTP) operates continuously, 24 hours a day, seven days a week, providing tertiary-level wastewater treatment for the Thousand Oaks community. On average, the facility treats eight million gallons of wastewater daily through a comprehensive process that includes screening, grit removal, primary and secondary clarification, aeration with nutrient removal, multimedia filtration, and disinfection. The resulting high-quality effluent is then beneficially reused for agricultural irrigation and landscape watering.

In 2010, the City implemented the HCTP North and South Headworks Upgrades Project (CI 5061) to modernize the preliminary treatment facilities that serve as the initial processing point for all influent entering the plant. The headworks system is responsible for removing debris and inorganic materials from raw wastewater before it enters downstream treatment processes. The project addressed operational inefficiencies associated with aging screening and grit removal equipment and included the installation of Huber fine screening equipment for removal of large solids, wash press equipment for dewatering, and grit separation equipment for removal of inorganic materials at both the North and South Headworks and remain in service to date.
In 2022, City Council approved construction of a new Fats, Oils, and Grease (FOG) Receiving Station (CI 5441), which went online in November 2024, to support the acceptance and processing of hauled FOG materials. The FOG station includes Huber strain press screening equipment for the removal of debris and inorganic materials prior to digestion and is an essential component of HCTP’s renewable energy production program.
DISCUSSION/ANALYSIS:
The Huber equipment serves as essential components of the headworks process and FOG Receiving Station screening systems, safeguarding downstream infrastructure. Continued reliability of this equipment is essential to maintaining treatment performance, preventing mechanical damage, and supporting regulatory compliance.
The units are proprietary in design and utilize manufacturer-specific internal components, controls, and software. Huber is the sole manufacturer and authorized service provider for this equipment and is the only entity authorized to supply proprietary replacement parts and perform manufacturer-supported repairs.
Because no other vendors are authorized to service this equipment, competitive procurement is not feasible and these services qualify for sole source procurement.
The proposed agreement provides scheduled maintenance, repair services, technical support, and access to proprietary replacement parts for a term of five years in an amount not to exceed $172,568.25 (includes 20 percent reserve for unanticipated repairs). This service is necessary to maintain safe and reliable operation of the headworks and FOG Receiving Station screening systems.
Establishing a multi-year service agreement ensures continuity of service, predictable maintenance planning, and timely response to equipment failures that could otherwise disrupt treatment operations.

Approval of this agreement with Huber (Attachment #1) supports fiscally- responsible asset management by extending the service life of existing infrastructure, minimizing the risk of unplanned outages, and reducing the potential for costly emergency repairs or premature capital replacement.
