Carpinteria’s national recognition shines for small wastewater systems
On April 9, at the CWEA Annual Conference in Sacramento, the Carpinteria Sanitary District earned the statewide honor for outstanding performance, innovation, cost‑effectiveness, and superior operations. The award focuses on agencies operating fewer than 250 miles of sewer pipeline.
Carpinteria’s achievement marks the district’s third time winning this distinction. In Marin County terms, it’s proof that a small system can punch well above its weight through disciplined maintenance and modern technology.
District Operations Manager Mark Bennett said a two‑year push for continuous improvement—especially in collection system maintenance and customer service—drove the win. “We’ve kept our eyes on the goal of protecting public health and the environment,” he shared, giving credit to the entire team’s commitment.
Travis Kearney, the Collection System Supervisor, credited wastewater professionals for sustaining top performance and reliability for the community Carpinteria serves. The recognition feels like a nod to everyone’s hard work, not just a trophy for the shelf.
What set Carpinteria apart in 2025
To earn the award, Carpinteria crews completed a rapid, system‑wide cleaning and CCTV inspection of about 45 miles of buried sewer pipelines. This effort showed how a small district can use modern tools to boost health, safety, and efficiency across the grid.
Crews now use field tablets and high‑quality digital video for inspections. They’ve paired that with computerized system mapping and workflow software.
This combo has led to an excellent compliance history with very few sewer overflows or blockages. That’s a critical metric for any coastal community, especially one balancing growth, drought worries, and environmental stewardship.
A closer look at Carpinteria’s system and history
Formed in 1928, the independent special district serves about 16,500 people (around 4,300 user accounts). It operates about 45 miles of pipeline with eight pump stations feeding a municipal wastewater treatment plant.
The scale is modest by statewide standards, but it really shows what persistent maintenance, smart technology, and strong customer service can achieve. In Marin County, plenty of smaller towns are facing aging infrastructure while trying to upgrade and protect streams, bays, and the coastline.
For Marin communities—from San Anselmo and Novato to San Rafael and Larkspur—Carpinteria’s approach is a practical template. Invest in comprehensive cleaning, adopt CCTV for proactive detection, and digitize mapping and workflows to keep operations transparent and responsive.
Meet the team behind Carpinteria’s progress
Behind the award‑winning numbers, you’ll find dedicated people who keep the system running. Beyond Bennett and Kearney, technicians and field crews handle routine maintenance to prevent problems before they reach residents.
The district’s leadership puts continuous improvement and customer service excellence at the core of daily work. It’s a simple formula, but it takes real commitment.
- Mark Bennett — District Operations Manager, champion of maintenance and service quality
- Travis Kearney — Collection System Supervisor, steward of safety and performance
- Dedicated wastewater professionals whose daily tasks protect public health and the environment
What this award means for residents and ratepayers
For people in the Carpinteria community and nearby Marin, this recognition actually matters. It means fewer sewer overflows, fewer blockages, and a district that can jump on problems fast.
The team invested in field-tested tech, digital inspection videos, and integrated mapping. That keeps operations efficient and still meets strict environmental rules.
In Marin County, folks want the same thing—cleaner waterways, safer neighborhoods, and honest reporting that builds trust between public districts and residents.
Carpinteria’s approach nudges other small districts to try more aggressive maintenance cycles and smarter data tools. Marin towns keep an eye on their aging lines and new developments, so this model feels practical: strong frontline work plus modern info systems to protect health, habitat, and reliable service—especially for communities by rivers, bays, or the Pacific.
