We've been seeing a lot of wipes coming into the plant, and they've been causing difficulty in our system. This picture shows just a portion of the wipes collected on Saturday and Sunday. We know there's wipe for every purpose these days, and we understand that you might choose to use them. Once you're done using them, the only place for them to go is in the trash. There are no truly "flushable wipes"- they will not break down in our system and can cause clogs or interfere with machinery. Please put all wipes in the trash can!

We're excited to announce that our Open House will be held on Saturday, October 17th from 10am to 2pm here at NapaSan! Take a tour of the treatment plant to find out what happens to your water after it goes down the drain and how NapaSan gives much of that water a new purpose! Tours will be given every half hour from 10:30am to 1:00pm. There will be games and activities for kids, equipment demos, refreshments, and more!
We're bringing back toilet races to our event this year for some unique fun! Have you ever wanted to ride a motorized toilet and race your friends? You're in luck! Join us at the Open House and ride a "Gotta Go Racer!" Visit www.napasan.com for more information.
