Sewer Systems
Updated: Oct 10
Each time you flush the toilet or wash something down the drain, you create sewage, also known as wastewater. It contains all the deject you see as well as all the harmful bacteria that you don’t. Human waste naturally contains coliform bacteria – for example, E. coli – and other bacteria that can cause diseases.
Once water becomes infected with these bacteria, it becomes a health hazard. It contains suspended solids and chemicals that affect the environment and can be very harmful to anyone in contact with it, so next time you need a new sewer line or repairs to an existing system, don’t touch the poo. Call us and we will touch it for you.

The lateral is yours, and that surprises most owners
The pipe running from your house to the city main is the sewer lateral, and on most properties the owner is responsible for it, frequently all the way to the connection at the main.
That means a failure in the street can still be your repair. It is worth knowing which jurisdiction you are in and where their responsibility begins, before you need the answer.
What actually fails
Root intrusion. Roots find the joints in older clay pipe and grow into them. This is the most common cause of a backed-up lateral in an older neighborhood
Clay pipe joints, which were never watertight to begin with and separate as the ground moves
Cast iron, which corrodes and scales until the opening closes
Bellies. A section that has sagged so waste sits in it instead of running through
Offsets and collapses, where ground movement has pulled a joint apart
On expansive clay soils, all of the above accelerate, because the ground around the pipe moves seasonally
Find out before you dig
A camera inspection is the difference between a diagnosis and a guess, and it is cheap relative to any repair.
It tells you what the problem is, exactly how far from the house it is, and how deep. Those three facts decide which repair applies and what it costs. Digging without them is how a spot repair turns into a trench.
If you are buying a property built before the 1970s, a lateral camera inspection is one of the highest-value inspections available and one of the least commonly ordered.
The repair options, cheapest to most involved
Clearing and root cutting. Restores flow and does not fix the cause. Appropriate as maintenance, not as a solution
Spot repair. Excavating and replacing a defined failed section. The right answer for a single offset or collapse
Trenchless lining. A liner cured in place inside the existing pipe. Avoids the trench, and needs the existing pipe to be intact enough to line
Pipe bursting. Pulls a new pipe through the old one, fracturing it outward. Works where lining will not
Full replacement by open trench. The most disruptive, and sometimes the only option where the line has collapsed or the grade has to be corrected
Any of them is permitted work and inspected. And where the line runs under a street or sidewalk, the work in the public right of way carries its own separate permit from a different department.
Septic is a different conversation
Large parts of unincorporated Riverside County are on septic rather than sewer, and that changes everything from maintenance to what you are allowed to add to the property. It is the single most common obstacle to adding a dwelling unit: building an ADU in Temecula and Murrieta.
