The cost to put in well and septic on raw land runs roughly $10,000 to $26,000 combined on a straightforward site — and dramatically more on a difficult one. Those two line items are the most commonly underestimated numbers in rural home building.
Add access, power and a driveway and you have the real answer to what raw land costs before a foundation exists. Here is the whole picture, with published figures and the site conditions that move them.
Key takeaways
- A 200-foot well runs $6,000 to $16,000; the national average is about $10,500.
- A conventional septic system runs $3,500 to $8,500. Engineered systems reach $50,000+.
- A percolation test costs $250 to $700 and should happen before you close on land.
- Driveway, power and propane are separate and often larger than expected.
- Well depth is the least predictable number on a rural build.

What Does It Cost to Drill a Well?
$30 to $80 per foot for a complete installation, according to HomeGuide’s well drilling cost data. Drilling alone is $20 to $30 per foot.
| Item | Published cost | Notes |
|---|---|---|
| Complete well installation | $30 – $80+ per foot | Includes drilling, casing and basic components |
| Drilling only | $20 – $30 per foot | Before casing, pump and connection |
| Typical 200-foot well | $6,000 – $16,000 | National average around $10,500 |
| Well pump | $400 – $2,500 | Depth and flow rate drive the choice |
| PVC casing | $7 – $11 per foot | Standard on most residential wells |
| Steel casing | $30 – $130+ per foot | Required in some geology |
Residential wells typically run 100 to 300 feet deep. That range is the problem: you do not know the depth until somebody drills, which means the cost to put in well and septic carries genuine uncertainty until the work happens. A neighbouring parcel’s well log is the best predictor available before you commit.
What Does a Septic System Cost?
$3,500 to $8,500 for a conventional system. Poor soils change that answer completely.
| System type | Published cost | When it is required |
|---|---|---|
| Conventional / anaerobic | $3,500 – $8,500 | Good soil, adequate space, suitable water table |
| Chambered | $4,000 – $11,000 | Where a standard leach field will not fit |
| Drip distribution | $6,500 – $15,000 | Shallow soils |
| Constructed wetland | $7,000 – $14,000 | Specific site and regulatory conditions |
| Aerobic treatment unit | $20,000 – $40,000+ | Poor percolation |
| Mound system | $25,000 – $50,000+ | High water table or shallow bedrock |
| Perc / soil testing | $250 – $700 | Always. Deep-hole tests can reach $2,000 |

Access, Power, and the Driveway
Well and septic are only two of five site costs. The others catch people out just as often.
- Legal and physical access. An easement on paper is not the same as a road a concrete truck can climb.
- Driveway construction. It has to carry ready-mix trucks, lumber deliveries and a crane. Length, grade and base material drive the cost.
- Power service. Distance to the nearest utility pole is the whole equation. Long runs can exceed the cost of the foundation.
- Off-grid alternative. Solar with battery storage is sometimes cheaper than a long utility extension. It is a real comparison worth running.
- Propane. Tank, line and placement, since natural gas rarely reaches rural parcels.
What to Check Before You Buy the Land
These checks cost hundreds. Skipping them costs tens of thousands.
| Check | Approximate cost | What it tells you |
|---|---|---|
| Percolation test | $250 – $700 | Which septic system your soil requires |
| Neighbouring well logs | Free | Likely depth and yield in that area |
| County zoning and setbacks | Free | Whether your footprint fits |
| Utility distance quote | Free | What power service will cost |
| Access review with a builder | Varies | Whether trucks and a crane can reach the site |
Putting a Real Number Together
The published ranges above tell you the shape of the cost to put in well and septic. They cannot tell you your number, because your number depends on depth, soil, distance and grade — all of which are specific to one parcel.
That is why a site review comes before a construction budget, and why custom projects begin with a design agreement rather than a construction contract. Related reading: log cabin cost breakdown and our general contracting services.

Frequently asked questions
What is the cost to put in well and septic on raw land?
Budget roughly $10,000 to $26,000 combined for a straightforward site — about $6,000 to $16,000 for a 200-foot well and $3,500 to $8,500 for a conventional septic system, per HomeGuide. Difficult sites go far higher: an engineered mound septic system alone runs $25,000 to $50,000 or more.
How much does it cost to drill a well?
$30 to $80 per foot for complete installation, or $20 to $30 per foot for drilling alone. An average 200-foot residential well runs $6,000 to $16,000, with a national average near $10,500. Add $400 to $2,500 for the pump.
How deep does a residential well need to be?
Residential wells typically run 100 to 300 feet. Depth depends entirely on local geology and water table, which is why a well is the single least predictable line item on a rural build budget.
How much does a septic system cost?
A conventional system runs $3,500 to $8,500. Alternative systems run $4,000 to $15,000, and engineered systems — including mound systems required on poor soils — run $15,000 to $50,000 or more. Soil percolation testing costs $250 to $700.
What is a perc test and do I need one before buying land?
A percolation test measures how fast soil absorbs water and determines what septic system your land requires. It costs $250 to $700, and it is the cheapest insurance you can buy before closing on rural property.
What else does raw land need before you can build?
Legal and physical access, a driveway capable of carrying concrete trucks and cranes, power service or an off-grid system, and often propane. On remote parcels these can cost more than the foundation.
Can I get a construction loan on land with no utilities?
Usually harder. Lenders want to see a path to a certificate of occupancy, which means demonstrating water, septic and access are viable. Getting those answers before closing on land protects the whole project.
