Direct answer: An independent water source usually means a drilled or driven well with a submersible pump, plus a hand pump as a backup and a filtration-and-testing routine. Cost and feasibility depend entirely on local geology and permit rules, so the first step is a call to your local health department, not a equipment purchase.
Well options
| Type | Depth | Typical cost | Notes |
|---|---|---|---|
| Driven point | 10–30 ft | $300–$1,500 | Only in sandy, shallow water tables; easy to install and easy to contaminate |
| Drilled | 50–300 ft | $3,000–$12,000 | Standard modern well, requires a contractor and permit |
| Dug | 10–30 ft | $1,500–$6,000 | Wide, shallow, vulnerable to runoff; historic style |
| Spring development | Surface | Varies | Needs a spring box and protection from animals |
Before drilling, ask neighbours about depth and yield, check the local well registry if one exists, and get a water quality test from a nearby well. A well that produces 2 gallons per minute is enough for a household with storage; 20 gallons per minute is a different budget.
Hand pump next to the house
A hand pump is insurance against power loss. The practical options are a deep-well hand pump installed alongside the electric submersible (a "two-pipe" setup), or a shallow pitcher pump on a separate sand-point well for garden water. Expect $400–$1,500 for a good deep-well hand pump plus installation.
Test it before you need it. A hand pump that has not been used in three years will need a new leather and a lot of priming.
Filtration and testing
Test well water at least annually for bacteria (total coliform and E. coli), nitrates, and anything local geology suggests — arsenic, iron, manganese, hardness, or radon. A basic lab panel costs $50–$150.
- Sediment: 5-micron cartridge ahead of everything else.
- Bacteria: UV sterilizer or shock chlorination, depending on the source.
- Chemicals: carbon block for taste and organic compounds; specific media for arsenic or iron.
- Hardness: softener if scale is a problem, not otherwise.
Water safety is local. Regulations for wells, setbacks, and potable use vary by state, province and country. Test your water, follow your local health authority's guidance, and do not treat any untreated source as safe to drink.
Frequently asked questions
How much does a well cost?
A drilled well typically runs $3,000–$12,000 depending on depth, geology, pump, and pressure tank. Driven points in sandy soil can be under $1,500.
Do I need a permit?
Usually yes for a drilled well, and often for any well used for drinking water. Permit rules are set locally — check before drilling.
Can I drink well water without treatment?
Only after testing confirms it is safe. Many wells need no treatment; some need UV, filtration, or softening. Test annually.
Pair a well with rainwater storage so a pump failure is inconvenient rather than an emergency. The water chapter in The Self-Sufficient Backyard covers catchment and storage together.
