Trusted well experts serving Temecula, Murrieta, Hemet, and communities throughout Riverside County. From wine country vineyards to mountain homesteads, we deliver reliable well service backed by 20+ years of experience.
Southern California Well Service provides comprehensive well services throughout Riverside County. From the renowned vineyards and horse properties of Temecula wine country to the agricultural heartland of Hemet and the remote mountain communities of Anza and Aguanga, we bring over two decades of experience to every job.
Riverside County's diverse terrain — from valley floors to mountain highlands exceeding 5,000 feet — means well conditions vary dramatically. We understand these regional differences and customize our approach for each property's unique geology and water needs.
We service the southwestern and central portions of Riverside County, focusing on rural and semi-rural areas where wells are common. Each region has distinct characteristics that influence well drilling and pump system design.
Temecula and the surrounding wine country region features over 40 wineries dependent on well water for irrigation and operations. The area has decomposed granite overlying bedrock, with alluvial valleys providing better water yields. Many vineyard wells need substantial production — 20-50+ GPM — to support irrigation during the growing season. Horse properties are also common here, requiring reliable water for livestock, arenas, and pastures.
Typical well depth: 200-450 feet | Common yields: 10-50+ GPM
Murrieta and French Valley have seen rapid development, but many properties on the outskirts still rely on wells. The geology transitions from valley alluvium to decomposed granite on the hillsides. Older wells in this area sometimes need rehabilitation or deepening as water demands have increased. New construction often requires wells where municipal water isn't available.
Typical well depth: 250-400 feet | Common yields: 5-25 GPM
The Hemet and San Jacinto valley has excellent groundwater resources with thick alluvial deposits. This agricultural region supports citrus, avocados, and row crops — all requiring irrigation wells. The valley floor typically offers shallower drilling depths and good yields. Properties along the mountain foothills transition to harder rock formations.
Typical well depth: 150-350 feet (valley) / 300-500 feet (foothills) | Common yields: 10-100+ GPM
Anza and Aguanga sit at 3,500-4,500 feet elevation with dramatically different conditions than the valleys below. Hard granite bedrock dominates, and wells must tap into fracture systems for water. Drilling depths of 500-800+ feet are common, and yields tend to be lower. Many properties use storage tanks to buffer limited well production. Despite the challenges, these communities support cattle ranches, horse properties, and rural homesteads.
Typical well depth: 400-800+ feet | Common yields: 2-15 GPM
Idyllwild, Pine Cove, and the surrounding San Jacinto Mountain communities face challenging drilling conditions in fractured granite at elevations above 5,000 feet. Wells here require specialized mountain drilling equipment. Water quality is generally excellent, but yields can be unpredictable. Many cabins and homes have wells that were drilled decades ago and may need rehabilitation or pump upgrades.
Typical well depth: 400-700 feet | Common yields: 1-10 GPM

Riverside County's varied geology and agricultural water demands create specific challenges. Knowing what to watch for helps you catch problems early.
Vineyard and orchard wells run heavily during summer months. Pumps designed for residential use often fail prematurely when pushed to meet agricultural demands. Proper pump sizing and VFD controllers help systems handle peak irrigation seasons.
Some mountain wells have seen water levels drop over the past decade. Wells that produced well at 400 feet may now need pumps lowered to 600+ feet. Monitoring water levels helps plan for pump depth adjustments before you run dry.
Much of Riverside County has hard water with elevated calcium and magnesium. This causes scale buildup in irrigation systems, pressure tanks, and household plumbing. Water softeners protect equipment and improve water quality.
Alluvial wells in the Hemet and San Jacinto valley can produce sand, especially when over-pumped. Sand damages pump impellers and clogs irrigation systems. Proper screen installation and pump sizing prevents this issue.
Mountain communities like Anza and Idyllwild experience frequent thunderstorms. Lightning strikes and power surges destroy pump motors and control boxes. Surge protection is essential for exposed rural properties.
Well drilling costs depend heavily on location and geological conditions. Here's what to expect across different areas of Riverside County:
| Area | Typical Depth | Drilling Cost Range* |
|---|---|---|
| Temecula Wine Country | 200-400 ft | $18,000-$35,000 |
| Hemet/San Jacinto Valley | 150-350 ft | $15,000-$30,000 |
| Murrieta/Menifee | 250-450 ft | $20,000-$40,000 |
| Anza/Aguanga | 400-800+ ft | $35,000-$70,000+ |
| Idyllwild/Mountain | 400-700 ft | $35,000-$60,000 |

Riverside County has significant agricultural operations that depend on reliable well water. We specialize in wells that support:
"Our vineyard in Temecula needed a new irrigation well that could handle our expansion. Southern California Well Service drilled us a well that produces over 40 GPM — more than enough for our 20-acre expansion. They also set up a VFD system that adjusts pump speed to match our irrigation demands. Couldn't be happier with the results."

New agricultural well with VFD control system
A cattle ranch in Anza noticed their 20-year-old well was struggling to keep up with summer demand. Water pressure dropped during peak usage, and the pump was cycling frequently. Our video inspection revealed the pump was only 50 feet above the current water level — dangerously close to running dry.
We pulled the pump and reinstalled it 150 feet deeper, below the seasonal water fluctuation zone. We also installed a low-water cutoff to protect the pump if levels drop further. The ranch now has reliable water year-round, even during drought conditions.
Result: Reliable water restored with protective controls for future drought conditions.
"We have a horse property in Murrieta and our well pump failed on a Saturday. With 8 horses needing water, it was an emergency. The crew came out the same day, diagnosed a burned motor, and had a replacement installed by Sunday evening. They even showed us how to prevent this in the future with a surge protector."

Emergency weekend pump replacement
Vineyard irrigation needs vary by acreage, soil type, and grape variety. A rough rule is 1-2 GPM per acre during peak irrigation. A 20-acre vineyard might need 20-40 GPM. We help size wells and storage systems to match your specific operation.
The mountain communities have hard granite bedrock that requires slower, more difficult drilling. Wells typically need to go much deeper — often 600-800+ feet — to reach adequate water. The combination of harder rock and deeper drilling increases costs significantly.
Yes, but the system needs proper design. Agricultural wells often use larger pumps and higher flow rates that can be hard on household plumbing. We typically recommend a pressure tank and flow controls to deliver appropriate pressure for indoor use while still supporting irrigation.
Riverside County requires a well permit for all new wells. The county also has setback requirements from septic systems, property lines, and structures. Some areas have additional groundwater management requirements. We handle the permitting process as part of our drilling service.
Signs of sand production include gritty water, sediment in toilets and water heaters, and reduced water pressure. You might also notice pump noise changes or shortened pump life. A video inspection can identify the source of sand infiltration.
Storage tanks are especially valuable for low-yield wells or properties with high peak demands. A 2,500-5,000 gallon tank allows a slower well to "catch up" overnight while providing adequate flow during the day. They're common on Anza/Aguanga properties and vineyards.
A Variable Frequency Drive (VFD) controller adjusts pump motor speed to match actual water demand. Instead of cycling on/off, the pump runs continuously at lower speeds. This extends pump life, saves energy, and provides constant pressure. VFDs are ideal for vineyard and agricultural wells.
