Have you or someone you know experienced a sewer back up into a residence, business, or other structure? If so, you know backups can cause unpleasant and costly damage. But, did you know that the backup could have been prevented?

Regular Maintenance

The Montecito Sanitary District sewer system relies on gravity flow to operate. Regular maintenance of your lateral line, which drains into the District's sewer main, will prevent obstructed flow by maintaining a positive flow in your lateral line. Age and material of your lateral line plays a factor as well. Roots from trees and large shrubs and plants are attracted to water and if your lateral line is cracked, roots will gravitate towards the water source, enter the lateral line and eventually obstruct flow.

Backwater Valve (a.k.a. Back Flow Device)

A backwater valve can be installed onto some lateral lines to prevent sewer backups. This device is required by law under certain circumstances. Homes, businesses, and other structures with drainage fixtures such as a shower pan, tub, toilet or sink rim which are located below the elevation of the next upstream manhole cover, are required to install and maintain an "approved" backwater valve. Installation of such devices requires a permit. You should contact a licensed plumber to determine the need for such a device or if another suitable alternative exists. If you already have a backwater valve, call a licensed plumber to verify that it is in good working order, because if it stops working, it may not prevent a backup.

Additional Measures

- Avoid disposing of bulky trash items through the sewer. Remember, your lateral line may be as small as three (3) inches in diameter.

- Do not dispose of substances such as oil, fat, or grease through the sewer. It is unlawful for anyone to dispose of such substances from whatever source through the sewer. Commercial operations such as restaurants are required to have a grease trap to prevent such an occurrence. Industrial waste generators are required to install a pretreatment facility to process waste prior to disposal.

- If you are not the property owner and want to protect against potential uninsurable damage to your personal property, give this notice to your landlord, manager, or property owner.
