Wells on Record
San Diego
County
Based on California DWR well completion reports. San Diego's average well depth is 358 feet shallower than the San Diego County average of 450 feet.
With 3,281 wells on record, San Diego has a well-established well infrastructure. The wide depth range of 1 to 1613 feet reflects the varied terrain and geology across San Diego's landscape. Shallower wells typically tap into alluvial aquifers near drainages, while deeper wells penetrate the Peninsular Ranges batholith, primarily granitic and metamorphic rock to reach more reliable water sources.
At an average depth of 92 feet, drilling in San Diego typically costs between $4,140 and $6,900 depending on formation hardness and casing requirements. See detailed well depth data for San Diego →
Drilling Conditions in San Diego
Well drilling in San Diego typically encounters the Peninsular Ranges batholith, primarily granitic and metamorphic rock. Most wells can be completed in 1-3 days under normal conditions. The relatively moderate depths keep drilling costs reasonable, though rocky formations can slow progress.
San Diego County requires a well permit from the Department of Environmental Health (DEH) before drilling can begin. The permit process typically takes 2-4 weeks and costs $800-$1,500 depending on the parcel. We handle the entire permit process for San Diego properties.
