Project Details

To continue to provide reliable sewer service and protect the environment, work must be done to rehabilitate areas of the sewer system that are in poor condition.

Who will be doing this work?

NapaSan has contracted with Glosage Engineering Inc., Southwest Pipeline & Trenchless Corp., and Easy Flow to perform this sewer rehabilitation work.

What type of work will be done?

The rehabilitation work will fix the lateral, or pipe, that extends from the sewer pipeline in the street to the property line. The diagram below illustrates the public and private sewer lateral locations. In some areas, the sewer lines will be repaired or replaced using cured-in-place pipe lining. Sewer cleanout installations or replacements will be necessary at some properties, and some sewer work in the street will need to be performed. You will receive a door hanger the week prior to any work taking place that will notify you of the type of work to be done at your property.

What can I expect when this work is being performed?

Sewer cleanout installation or replacement involves digging a hole in the front yard near the property line. Landscaping and hardscaping in the areas where digging take place will be restored to the satisfaction of the property owner. See the photos below that illustrate a newly installed sewer cleanout.

There will be a brief disruption in your sewer service when this work is being performed, which is anticipated to be a single working day for individual properties. During this time, we ask that you keep water and sewer usage to a minimum.
