During the Millbrae City Council Regular Meeting on September 23, 2025, significant discussions centered around the recent installation of a new sewage solids grinder at the Madrone Pump Station, as well as pollution prevention initiatives and environmental programs.

City Engineer Ahmad Haya presented an update on the newly installed grinder, known as the "Muffin Monster," which replaces an older model and is specifically designed to handle non-dispersible materials like wet wipes. This upgrade is crucial as it addresses ongoing challenges faced by the city's wastewater collection system, which spans approximately 60 miles and directs sewage to the treatment plant. Haya highlighted the financial implications of clogged systems, citing examples from other cities that have incurred substantial costs due to similar issues. The new grinder is expected to reduce operational downtime and maintenance costs significantly, as it effectively processes materials that would otherwise lead to blockages.

The council members expressed their appreciation for the Public Works staff's efforts in managing these challenges and discussed the broader implications of consumer behavior regarding the disposal of wet wipes. Haya emphasized the importance of public awareness, urging residents not to flush wipes, which can cause severe plumbing issues in both public and private systems.

In addition to the sewage grinder discussion, the meeting included a presentation by Senior Environmental Programs Manager Andrea Papajohn on pollution prevention initiatives. She outlined various programs aimed at increasing community awareness about proper waste disposal and recycling practices. Papajohn introduced two no-charge services for residents: on-call cleanups and drop-off services for hazardous waste at Blue Line Transfer. She also discussed available rebates for environmentally friendly practices, such as lawn replacement and rainwater capture systems.

The council's discussions underscored the city's commitment to improving its infrastructure and promoting sustainable practices among residents. As Millbrae continues to address the challenges of waste management and environmental conservation, the installation of the new grinder and the introduction of pollution prevention programs represent proactive steps toward a more sustainable future. The council plans to monitor the effectiveness of these initiatives and engage the community in ongoing environmental efforts.
