Well characteristics
Across the wells Southwest Pump & Drilling Inc. has drilled, the median depth is 740 ft (middle half 500 ft–996 ft), median tested yield 1,500 gpm, and median static water level 178 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1996–2026" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
