County Sanitation District No. 2-3 of Santa Clara County


Our office is now open to public. In-person permit counter service hours are Monday - Friday, 10am-3pm. For in-person service outside of the daily hours, an appointment is required.   To get in touch with us please call 408-255-2137 or send an email to 

The safety of our customer, employees, and families remains our number one priority and we continue to follow CDC guidelines.  We thank you for your patience and cooperation during this uneasy time.



We know you’re working hard to keep yourselves healthy during COVID19 Shelter-in-Place. Help us keep our sewers healthy as well. Remember to never flush wipes, paper towels, or tissues because they clog our pipes!

With so many people home all day now, there’s a lot of more water going down the sewer drain! Make sure to can the grease.  Pouring household grease down the drain is a major problem for us.  Our crews are working hard 24/7 to keep our systems up and running.

With the shortage of toilet paper, there is a greater potential to use wipes. Just remember: Save your sewer pipes!  No matter what the label says, don’t flush them –place them in the trash instead.
