Get to Know Your Lateral & Protect Your Investment

Your home’s sanitary sewer lateral consists of the upper lateral, typically installed within two feet of the building structure to the property line and the lower lateral, which is installed from the property line to a fitting that connects to the mainline. The sanitary sewer lateral is the private property of the building owner, who is responsible for all the costs related to its repair and maintenance. A permit is required for any work performed on your lateral and can be obtained by calling MVSD at 925-228-5635 ext. 10 or email to info@mvsd.org.

Protect your investment by locating your home’s sewer cleanout and installing an overflow protection device. Your cleanout is typically found outside of your home or just behind the sidewalk on your property. This will be a pipe with a screw cap that has a square knob or an indentation on the top.

backwater sewer overflow device — Example of a sewer relief valve

An overflow protection device, also known as a sewer relief valve or popper, is designed to help you avoid costly repairs or damage caused by a sewage backup. It allows sewage to escape outside the home in the event of a lateral blockage and allows an access point to clear and inspect your lateral. Consult a professional to ensure proper installation and maintenance.

Should you experience a sewer backup or overflow incident, please notify the District 24 hours a day, 7 days a week at 925-228-5635.

Make Your Holidays FOG-less

With the holidays approaching, you can almost smell the delicious food that comes with it. The last thing you want to smell is a sewer blockage caused by fats, oils and grease.

Fall is Here!

You know fall is here when the air starts to cool, and the leaves change colors and fall to the ground. Leaves in streets and gutters add higher than normal nutrients and lower than normal oxygen to local water bodies which can negatively affect the ecosystem.
