In an effort to reduce sewer system backups, La Mesa properties with building plumbing fixtures situated less than two feet above the nearest upstream manhole cover, will be required to install a sewer backwater valve on the building sewer lateral serving the property. It is the City of La Mesa’s policy to review permit applications and plan check submissions for private improvement projects to determine if the requirement applies to your home or business. Engineering plan check staff can provide more specific information.
If you are required to install the device, you may be eligible for reimbursement of one-half the cost of installation, up to $1,500. Refer to the Backflow Packet for specific details about the program. To request information and apply for reimbursement, please call 619.667.1338.
