Sewer lateral and septic excavation in San Bernardino
Verdemont Excavation refers sewer and septic work to one licensed contractor with the right classification. Here is how each job runs.
Replacing an old sewer lateral
The lateral is the pipe from your house to the city main, and in most of California the owner owns it. Homes built before about 1950 in Redlands, Colton and older San Bernardino usually have vitrified clay pipe with joints every few feet that roots love. Tracts from about 1945 to the early 1970s may have Orangeburg, a tar paper pipe that flattens and collapses.
A camera inspection first, typically $250 to $500, shows where the damage is. Open trench replacement of a 40 to 80 foot run with new PVC typically costs $4,500 to $12,000. The top of that range comes from depth, a driveway in the way, or a connection under the street that needs a street cut permit and traffic control.

Septic systems in San Bernardino County
Outside the sewer districts, homes in Devore, much of Yucaipa, the mountain communities and county islands run on septic. San Bernardino County Environmental Health permits new and replacement systems under the state rules set by the State Water Board OWTS policy. The EPA septic guide is a good plain explanation of how the tank and field work.
Everything starts with the perc test, which measures how fast water soaks into your soil. Good percolation means a tank and leach lines, typically $15,000 to $32,000 installed. Slow soil or shallow rock means seepage pits or an engineered system at $22,000 to $45,000.

Sewer and septic questions
How much does it cost to replace a sewer line in San Bernardino?
Usually $4,500 to $12,000 by open trench for a 40 to 80 foot lateral. A street cut or a deep line pushes it to the top. A camera inspection first shows what you need.
What is Orangeburg pipe?
A fiber and tar pipe used from about 1945 to the early 1970s. It deforms and collapses with age, and a camera inspection that shows it oval or crushed means replacement.
How much is a new septic system in San Bernardino County?
A standard tank and leach field runs $15,000 to $32,000 installed. Slow perc or shallow rock moves you to seepage pits or an engineered system at $22,000 to $45,000.
Who approves septic systems here?
San Bernardino County Environmental Health permits septic systems across the county, including inside most cities, after a perc test and design review.
Can I add a bedroom on septic?
Only after showing the system can carry it. Septic is sized by bedroom count, so an ADU or added bedroom usually needs a county review and sometimes more leach field.
Towns where this comes up most: Yucaipa, Lake Arrowhead, Redlands, Devore, Colton.
