In Highland, East Valley Water District runs the sewer mains where sewer is available, and the line from your house to that main is private. Most clogs form between your fixtures and the street. Call the number on this page to be connected with a local plumber in Highland.
Highland's sewer and housing picture
Highland sits at the southern base of the San Bernardino Mountains, and its East Highland, West Highland and central neighborhoods grew in waves tied to citrus and the railroads. The City's plan-check rules require new structures to connect to sewer where it is available, subject to East Valley Water District (EVWD) review, and an EVWD availability letter on the City's site confirms EVWD water and sewer mains serving Highland property. In practice, if your home is on public sewer, EVWD handles the main and the private line from the house is the owner's.
About 44 percent of Highland homes were built before 1980, with the median year built at 1983 and the 1980s and 1990s the biggest building decades. Older houses can have cast iron drains and older yard piping where roots and scale catch debris. Newer homes usually have plastic lines that clog mainly from grease, hair and wipes.
Comparing drain cleaning options
| Problem | Typical fix | Notes |
|---|---|---|
| One sink or tub draining slowly | Trap cleaning or a small hand cable | Often a short visit |
| Kitchen sink backing up repeatedly | Machine cable, then jetting if grease returns | Grease rebuilds if habits do not change |
| Whole-house backup | Main line cleared from the cleanout | Stop using water until done |
| Clogs that keep returning | Camera inspection | Shows roots, sags or breaks |
Signs to act on
- Toilets that gurgle when a nearby sink drains
- Water rising in the tub during a load of laundry
- Slow drains in more than one bathroom
- A sewage odor near the cleanout or the yard
- Bubbling in the kitchen sink after the dishwasher runs
Seasonal and timing notes
Highland sits closer to the mountains than most of the valley, and an occasional heavy winter storm can soak the soil around older laterals and expose cracked joints. Long dry summers drive roots toward any moisture, including a leaking sewer joint. Holiday cooking reliably fills kitchen lines with grease. A single slow drain can wait for a weekday visit, which usually costs less than an evening or weekend call. If a repair is needed, the City of Highland Building & Safety Division requires permits for plumbing system work.
