In Highland, East Valley Water District handles sewer collection where public sewer is available, and the private line from a house to EVWD's main is the owner's to repair. Roots, cracks and sags in that line are jobs for a plumber. Call the number on this page to be connected with a local plumber in Highland.
Local conditions in Highland
Highland's plan-check rules require structures to connect to sewer where it is available, subject to East Valley Water District (EVWD) review, and EVWD has water and sewer mains along at least some Highland streets. EVWD's sewer footprint and treatment agency can vary by address, so if you are not sure your home is on public sewer, check your bill or ask EVWD.
Housing age matters here. Point2Homes, using Census survey data, puts Highland's median year built at 1983, with about 44% of homes built before 1980 and the 1980s and 1990s as the biggest building decades. Older homes around the Palm Avenue historic district and other early neighborhoods are where clay or cast iron laterals are most likely, with joints that roots can enter. Homes from the building boom that followed generally have plastic pipe that is now 25 to 40 years old, old enough for settled sections and root entry at fittings. Where mature trees stand close to a lateral, root intrusion becomes the most likely cause of repeat clogs.
Repair options compared
| Option | Works well for | Limits |
|---|---|---|
| Cable or jet cleaning | Grease, paper, light roots | Damage stays; roots return |
| Spot repair | One broken joint or crack | Requires an access pit |
| Cured-in-place lining | Leaky joints along a sound pipe | Cannot correct a sag |
| Replacement | Long failed or bellied runs | Largest scope and restoration |
Signs to watch for
- Gurgling from a toilet as other drains run
- Backup in the lowest tub or shower
- Clogs returning after cleaning
- Sewage odor or a soggy area over the line outside
Timing and seasonal notes
Highland sits at the base of the San Bernardino Mountains, and winter storms there can be heavy. Wet ground and high flows are often what turn a partly blocked lateral into a full backup. In summer, roots chase moisture into any leaking joint. A dry-season camera inspection lets you plan the fix rather than react to the next backup. Permits for plumbing systems come from the City of Highland Building & Safety Division, 27215 Base Line, with the permit counter at (909) 864-8732 x232.
