Where Desert Knolls is
Desert Knolls appears on mapping sources as a populated place inside the Town of Apple Valley, and it is also the name of an Apple Valley Unified School District elementary school at 18213 Symeron Road, ZIP code 92307. Residents use the name for the surrounding streets, though no official boundary has been published that we could find.
Listing sites use related labels such as Upper Desert Knolls and Desert Knolls Manor for parts of the same general area. We treat them as one residential area here instead of three separate places, and we ask for your street address when you call so we know exactly where you are.
Desert Knolls at a glance
A school landmark
Desert Knolls Elementary opened in 1961 under the Victor Elementary School District and joined the Apple Valley Unified School District in 1987. It is one of nine elementary schools in town.
Home ages vary
One listing site says the community dates to 1952 with homes built from 1955 onward, while another profile says most homes date to the early 1980s. Treat both as rough guides.
Housing types
A real estate profile estimates about 72 percent detached single-family homes, with mobile homes, small multiplex buildings and apartments making up the rest.
Lot sizes
Listing data shows lots up to about an acre, which leaves room for yard water lines, sprinklers and sometimes a septic tank.
Septic, sewer and water in Desert Knolls
According to the Town's planning documents, roughly 30 percent of development is sewered and roughly 70 percent is septic across the whole Town. We cannot say which applies to your street, so check your records or look for a cleanout and a tank lid. If a toilet and a tub back up together, the cause could be the house line, the tank or the drain field.
Water comes from several purveyors. The Town lists 11, and Liberty Utilities serves about 81 percent of Apple Valley, so your bill is the right place to find your utility. Liberty's 2022 data shows hardness between 57 and 130 ppm, which is moderate, and scale can build up in a water heater over time.
Cesspools are prohibited in Apple Valley, and tank pumping and drain field work belong to a septic professional. We clear and inspect lines, and we will tell you plainly when a problem is outside our work.

Services that fit Desert Knolls homes
- Repeat backups. Sewage or water backing up in more than one fixture points to the main line, so ask about sewer line cleaning and a sewer inspection.
- Everyday clogs. Sinks, tubs and showers that drain slowly usually need drain cleaning.
- Yard and slab water loss. A high water bill or wet ground between the meter and the house calls for leak detection.
- Hot water. A tank that leaks or no longer heats is a case for water heater repair or water heater replacement.
