Milpitas City Council certifies 2025 Sewer System Management Plan for public health safety

During the Milpitas City Council meeting on June 17, 2025, a significant focus was placed on the city's sewer system management, highlighting the importance of maintaining public health and environmental safety. Katie Duranzo, the director of public works, presented a comprehensive overview of the city's Sewer System Management Plan (SSMP), which is crucial for ensuring the effective operation and maintenance of the sewer collection system.

Duranzo emphasized that approximately 70% of the sewer infrastructure was built before 1990, underscoring the need for ongoing maintenance and upgrades. The SSMP is designed to prevent sewer spills, known as sanitary sewer overflows (SSOs), which can pose serious risks to public health and the environment. The plan includes a detailed response strategy for any spills that may occur, ensuring that incidents are reported and managed efficiently.

One of the key elements discussed was the city's proactive approach to managing fats, oils, and grease (FOG) from food establishments, which are significant contributors to sewer blockages. The city conducts regular inspections of grease traps and interceptors in restaurants to prevent these materials from entering the sewer system. Duranzo also noted that tree roots can cause blockages, particularly in residential areas, and the city employs methods to mitigate this issue.

The council members expressed their support for the SSMP, with Council Member Chua highlighting that Milpitas is trending better than the state average in terms of sewer spills. The council unanimously voted to adopt the updated SSMP, which will serve as a living document, subject to review and updates every six years.

In conclusion, the meeting underscored the city's commitment to maintaining a safe and efficient sewer system, which is vital for protecting public health and the environment. The proactive measures outlined in the SSMP reflect Milpitas' dedication to addressing community needs and ensuring the sustainability of its infrastructure.
