do I locate my lateral?
Your home may have one of the following: A cleanout just outside
of the building or just behind the sidewalk on your property which
may be marked with the letter “S” or word “SEWER” on the cover;
or there may may be an “S” stamped on the curb in front of your
property (we have observed that the "S" does not always
accurately mark the lateral location.) Some older homes may not
have any cleanouts or markings to help locate your lateral. Please
call (510) 477-7500 or send an email to ContactUSD@Unionsanitary.com
and we may be able to provide an approximate location.
you have a list of approved Plumbers/Contractors?
USD does not keep a list of approved or recommended plumbers and
contractors. You may check the local Better Business Bureau,
on-line reviews, or a friend or acquaintance for any recommendations.
USD does recommend that you get a price quote from at least three
different licensed and bonded plumbers or contractors.
How do I start or stop
Service is never turned
on or off. The lateral to the property is connected to our sewer
system and does not require a phone call to Union Sanitary District
to start or stop service. If you have a septic tank on the property
that is in use to collect wastewater, you are NOT connected to the
sanitary sewer system. If you wish to abandon the septic tank and
connect to our system, contact USD regarding requirements and fees.
How do I put my
sewer bill in my name?
You do not need to take
any action to put your sewer bill in your name. USD's sewer service
charge is a line item on your annual property tax bill, and you
will not receive a separate bill from USD. The tax bill with our
fees included is sent to the registered owner of the property.

how the charges are calculated are provided below.
