Pipe Bursting in Victorville

Victorville sits on the Mojave River at the north end of the Cajon Pass, and for most of its history it was a railroad and highway town, with Old Town growing along Seventh Street and the old Route 66 alignment from the 1940s through the 1960s. The city's modern shape came later: the 1980s brought the first large tracts as commuters priced out of the valley moved up the hill, and the 1990s and 2000s filled in the land west toward the 395 and south toward Hesperia with subdivisions, shopping centers, and the Southern California Logistics Airport on the former George Air Force Base. The result is a city with a compact older core, broad areas of relatively young housing, and a rural fringe of large parcels where sewer service thins out and septic systems take over.

Trenchless sewer repair suits all three of those settings, and in the High Desert it has an extra advantage: it keeps you out of ground that is often cemented hard with caliche. The service area across San Bernardino County shows how far the service reaches; what follows is about Victorville specifically.

Desert soil, temperature swings, and pipe by era

Most of Victorville is underlain by sandy alluvium, with pockets of finer silt near the river and, over much of the plateau, layers of caliche at shallow depth. Sandy soil washes out from under a leaking pipe and leaves bellies, which is a problem on long laterals. Caliche does not move much, but it makes any excavation slow. The climate does the rest. Summer heat dries the soil and bakes shallow pipe; winter nights freeze the top of the ground; the daily temperature swing can exceed forty degrees. Pipe and joints that move with the soil every day for decades eventually loosen.

Old Town and the neighborhoods around it have vitrified clay laterals from the 1940s through the 1960s, some Orangeburg from the same period, and cast iron under the slabs of later mid-century houses. Many of these homes were on septic first and connected to sewer later, so the lateral route is not always obvious. The big cottonwoods, elms, and Chinese elms planted for shade in that era are the chief root offenders. The 1980s through 2000s tracts in Spring Valley Lake's neighbors, Brentwood, and the areas off Bear Valley Road are ABS plastic, with failures that are usually construction defects or settlement bellies rather than material decay. Outlying parcels have long laterals, sometimes well over a hundred feet, and a mix of materials depending on when they were connected.

Which method fits which problem

Start with hydro jetting to clear roots, scale, and sand, then a camera inspection and a surface locate. In Victorville the locate also tells the crew where caliche might be if a pit is needed.

• CIPP lining fits the Old Town clay that is rooted and leaking but still round, and it is the method of choice for long rural laterals where trenching the whole run would be a project in itself. The CIPP lining in plain language covers how the liner is saturated, installed, and cured.
• Pipe bursting fits Orangeburg, collapsed segments, and settlement bellies that a liner would follow. It needs a pit at each end, which the crew will site to avoid the worst caliche.
• Sectional point repair fits one crushed section of ABS or a single root-broken joint on an otherwise sound line.
• Spin-cast lining fits cast-iron drains under slabs and the larger lines serving the retail centers along Bear Valley Road and the logistics buildings at the airport.

Permits, locating, and responsibility

Within the city, permits come from the City of Victorville, which owns the local collection mains; treatment is handled by the Victor Valley Wastewater Reclamation Authority, the regional agency serving the Victor Valley cities. Unincorporated parcels go through San Bernardino County Land Use Services. The owner is responsible for the lateral from the building to the connection at the public main, including any portion under the street, and right-of-way work requires an encroachment permit. Every excavation starts with a DigAlert 811 notification. Victorville does not currently require a point-of-sale sewer inspection, though buyers of older and rural homes often request a scope, and a septic-to-sewer history is worth documenting.

What the estimate visit includes

Expect a camera run, a surface locate with depths, and a written scope naming the method, footage, and any pits. Keep the video and the sketch for your records.

Pipe Bursting in Victorville

How pipe bursting works

A steel cable is threaded through the old sewer line from a pit at one end to a pit at the other. A cone-shaped bursting head, with new high-density polyethylene pipe fused to it, is pulled through by a hydraulic unit. The head splits the old clay or cast iron outward into the soil and the new pipe follows in the same alignment at the same depth. The result is a single fused length of pipe with no joints for roots to find.

When bursting is the right call

• Collapsed sections — a liner needs a host pipe to hold its shape; a collapsed run has none.
• Bellies — a low spot that holds water stays a low spot after lining. Bursting lays new pipe on a fresh bed.
• Undersized lines — bursting can upsize a 3-inch lateral to 4 inches; lining slightly reduces diameter.
• Badly deformed pipe — Orangeburg that has flattened, or cast iron with most of its bottom gone.

What the job looks like

One pit at the house or cleanout, one at the property line or the street connection, each a few feet square. Utilities that cross within a foot or two of the sewer path are located and potholed first. The pull takes an hour or two; the whole job, including fusing, connections, inspection and backfill, is usually one day.

Permits and the street

If the downstream pit is in the sidewalk, parkway or street, a right-of-way permit and restoration to city standards are required in addition to the plumbing permit. If the connection at the main is replaced, the city inspects it before the pit closes. Confirm who is handling this before work starts.
