Flushable wipes are not flushable!  Although the packaging may state that wipes are flushable, that is not always accurate.  Wipes do not break down like toilet paper, causing havoc on your septic or sewer system.  When flushed down the toilet, wipes can cause major backups and clogs within the sewer lines. The toilet is not a trash can, so place wipes where they belong--in a real trash can. Additional information on non-flushable items can be found here: Think Before You Flush (PDF)

A sewer lateral is a pipe that carries wastewater (indoor water coming from toilets, washing machines, sinks, showers, etc.) from homes or businesses to the mainline sewer. The sewer lateral consists of upper lateral and service lateral (also called lower lateral) from the property line to the street. The mainline sewer is usually located under the street; it may also be located under an alley or in an easement on private property.

If you are experiencing slow draining or an overflow due to a sewer backup, it is requested that you contact the City of Davis Public Works Utilities and Operations Department by phone at 530-757-5686 between the hours of 7 a.m. and 3:30 p.m. or by the City’s Police Department non-emergency line after hours at 530-747-5400.  This will allow City staff to assess the situation as soon as possible, and to correct the problem (if it is in the sections of the pipe system maintained by the City) at no cost to the resident.

Calling the City directly can help to ensure as limited a delay as possible in responding, as City personnel do respond to all sanitary sewer calls from residents regardless of whether the resident initially calls the plumbing contractor or the City.

The property owner has the sole responsibility for clearing stoppages, inspecting, maintaining and repairing the upper sewer service lateral to avoid negative impacts to the operation and maintenance of the City’s sewer system. It’s the City’s responsibility to maintain service (lower) laterals. Typically, the responsibility delineation between the upper and service (lower) lateral is just past the upper lateral connection to the cleanout, which is usually located just behind the sidewalk on the property.

A. The City does not have service cleanouts nor service laterals in backyards. The property owner is responsible for any sewer lateral maintenance in backyards.

The City does not have service laterals in backyards, therefore the responsibility for repair in this situation would fall on the property owner.  If there are roots and or damage to the lateral, it will need to be cleared and or repaired by the property owner. If the problem is at the connection to the service lateral cleanout or the service lateral, the property owner/contractor will need an encroachment permit in order to expose the pipe for repair.

 

Contact the City of Davis Public Works Utilities and Operations Department by phone at 530-757-5686 between the hours of 7 a.m. and 3:30 p.m or by the City’s Police Department non-emergency line after hours at 530-747-5400. The City will dispatch a crew to inspect the line and assess the lateral. If there are roots in the line they will be cleared.

 

The upper lateral is privately owned and could be built from several different types of materials utilized by contractors over the years. The City’s cleaning equipment is quite aggressive and is designed for use in vitrified clay pipe. Depending on the type of material used in the upper lateral, the City’s equipment may damage the line.

You can contact the City’s Police Department non-emergency line after hours or on weekends/holidays at 530-747-5400 and they will contact the City’s standby personnel.

 

City employees are not permitted to recommend a specific plumbing contractor. Helpful information on finding (and hiring) a reliable contractor is provided to consumers by the California Contractors State License Board.
