Online Permit System

This section of the website is for the use of contractors and homeowners who require a permit for repair of a lateral sewer connection to the Oro Loma Sanitary District collection system.  There are two ways to obtain a lateral repair permit:

1.Request and pay for a permit online at this website.  You must first call our offices at 510-276-4700 to obtain a password to the website.  You must provide a valid email address to be used as your login name, and you will be assigned a password over the phone.  A valid credit card is required for payment, which is made through the Authorize.net secure payment service.  Once the required information is entered and the credit card payment is processed, the approved permit will be displayed in your Internet browser as an Adobe PDF file.  You must have Adobe Acrobat Reader installed in order to view and print the permit.  If you do not already have Acrobat Reader on your computer, you can download and install it here.

2.Visit the Oro Loma Sanitary District office, located at 2655 Grant Avenue, San Lorenzo, CA  94580 (map), between the hours of 8:00am to 12:00 noon, or 1:00pm to 5:00pm, Monday through Friday, excluding normal Federal holidays.  You can pay for a repair permit by check or credit card at the Oro Loma office.

Note: you must be a licensed contractor, or use a licensed contractor to perform the repair, if the work will require (a) exposing, repairing, or connecting to the sewer main in the street; (b) replacement of a “Y”-connector; or (c) replacement of the entire lateral line from the house to the street.  If the work is only from the house to the sidewalk, the homeowner may perform the work themselves.  If you have any question as to whether a licensed contractor is required, please call our Engineering Department at 510-276-4700 for assistance.
