The Southeast Treatment Plant (SEP) operates 24/7 to protect public health and the environment. San Francisco has relied on SEP to treat the majority of its wastewater for the past 70 years and we are making generational investments so this vital facility can continue to work around the clock.
As we continue to make progress with our infrastructure investments, we are proud to be providing jobs and contracting opportunities to local residents and businesses. When complete, the plant will work better, look better, and smell better for the community and entire City!
2023 will be one of the busiest years. Along Evans Avenue, the New Headworks Facility Project is expected to complete construction and begin testing. You will also see installation of our permanent art wall – and an improved streetscape -- along Evans Ave.
- With the peak of the work over the summer, expect additional vehicles and crews in the area with occasional inconveniences due to trucks and increased construction activities.
