Complete Well Water System Cost
Add up a complete well water system from your own line items — drilling and casing, pump, pressure tank, wiring, trenching and any water treatment — for a realistic all-in budget.
Calculator
A complete well water system on your line items — drilling $7,000.00, pump & tank $1,300.00, wiring & trenching $900.00 and treatment $1,000.00 — is about $10,200.00. Confirm siting, setbacks and the permit with a professional driller and your local health department.
A working well is a system, not just a hole. The rig time is only the start: you also pay for the pump that lifts the water, the pressure tank that keeps flow steady, the wiring and controls, the trench that carries the line to the house, and — if a lab test calls for it — treatment. This builder sums every line you enter so the total reflects water at the tap, not just a drilled borehole.
Enter the drilling and casing as one figure (bring it from the drilling cost tool if you like), then the rest. Every value is yours; the tool holds no price list, so it stays accurate whatever the market does.
Formula
Straight addition of your line items:
total = drilling & casing + pump + pressure tank + wiring + trenching + treatment
Leave any line at 0 if it does not apply — for example, set treatment to 0 until a certified lab test tells you what, if anything, your water needs.
Worked example
With $7,000 of drilling and casing, a $900 pump, a $400 pressure tank, $300 of wiring, $600 of trenching and $1,000 of treatment:
$7,000 + $900 + $400 + $300 + $600 + $1,000 = $10,200.
Drop the treatment line to $0 (water tests clean, no softener needed) and the same system is $9,200. The builder makes those trade-offs easy to see.
Budgeting the whole project
A complete-system view stops the classic surprise where a low drilling bid balloons once the pump, tank and trench are added. It also helps you split the work: some homeowners drill now and add treatment later, once a water test is back. Keep treatment at $0 until that lab result is in — sizing or buying treatment before you know what is in the water is guesswork.
For a percentage split of a target budget across these categories, use the budget allocator. For the drilling line on its own, the drilling cost tool separates footage from casing and adds a contingency. As with every tool here, this is a planning estimate on your figures — siting, setbacks and the permit belong to a professional well driller and your local health department.
