Well Water vs City Water: True Cost Over 10 Years

On paper, well water is free: no utility bill, no usage charges, no monthly meter fee. In practice, a private well comes with capital costs and recurring costs that often surprise new owners.

Capital: a new drilled well plus pump and pressure tank runs $4,500 to $15,000 depending on depth and geology. A first-time treatment train (sediment, iron filter, softener, UV) adds $2,500 to $6,000 installed. Most well owners inherit existing equipment but should budget for one full replacement cycle in any 10-year window.

Recurring: certified annual testing runs $50 to $300, salt for the softener is $5 to $15 per month, UV lamps are $80 to $140 per year, sediment cartridges are $30 to $100 per year, and well-pump electricity is $50 to $200 per year. Plan on a pump rebuild or replacement once every 10 to 15 years ($800 to $2,500).

City water in most metros runs $35 to $90 per month for a family of four including sewer. Over 10 years that is roughly $4,200 to $10,800.

Net result over 10 years for a 4-person household: well water typically lands at $7,000 to $14,000 of total ownership cost, city water at $4,200 to $10,800 plus whatever whole-house treatment you choose to add. Well water is rarely cheaper when fully costed, but homeowners value the independence, the avoided rate increases, and the lack of municipal additives.
