Well Water Treatment Cost

Understanding well-related costs helps you budget properly and avoid surprises. Prices vary significantly based on location, geology, depth, and the specific work needed. Here are realistic cost ranges based on our 30+ years of experience in San Diego, Riverside, and San Bernardino counties.

Well Drilling Costs

• Drilling per foot: $35–$65/foot depending on depth and geology
• Typical residential well (200–400 feet): $12,000–$25,000 complete
• Deep well (400–600+ feet): $25,000–$45,000 complete
• Permit fees: $800–$1,500 (San Diego County DEH)
• Site preparation/access: $500–$2,000 if grading is needed

These include drilling, casing, grout seal, well development, pump installation, pressure tank, and basic water testing. Mountain areas with hard granite (Julian, Palomar, Pine Valley) tend toward the higher end.

Pump and Equipment Costs

• Submersible pump replacement: $1,500–$5,000+ (depth-dependent)
• Pressure tank replacement: $400–$1,200
• Control box replacement: $200–$400
• Pressure switch: $150–$300
• Check valve: $150–$400
• Complete pump system (pump + tank + controls): $3,000–$8,000

Well Rehabilitation Costs

• Video inspection: $300–$600
• Chemical treatment: $1,000–$3,000
• Hydrofracturing: $3,000–$8,000
• Well deepening: $5,000–$15,000+ (depends on current depth and how much deeper)
• Well destruction (abandonment): $1,500–$5,000

Water Treatment System Costs

• Water softener: $1,000–$3,000 installed
• Iron/manganese filter: $800–$2,500 installed
• UV disinfection: $500–$1,500 installed
• Reverse osmosis (under-sink): $200–$600
• Shock chlorination: $200–$500
• Whole-house filtration system: $1,500–$5,000 installed

Water Storage System Costs

• 1,000-gallon poly tank: $800–$1,500 installed
• 2,500-gallon poly tank: $1,500–$3,000 installed
• 5,000-gallon poly tank: $3,000–$5,000 installed
• Booster pump system: $1,000–$2,500 additional

What Affects the Price?

Several factors cause significant price variation:

• Well depth: The single biggest cost factor. More depth = more pipe, wire, and labor.
• Geology: Hard granite drilling is slower and costs more per foot than softer formations.
• Access: Difficult access for the drilling rig (steep terrain, narrow roads) adds cost.
• Emergency vs. scheduled: After-hours and emergency service costs 25–50% more.
• Parts quality: We use quality components (Franklin Electric, Grundfos) because cheap pumps cost more in the long run.
