In short
- UF/IFAS puts a healthy horse at about 5 to 15 gallons of drinking water a day, so 10 horses need roughly 50 to 150 gallons before any hosing or washing.
- A new well in Marion County goes through a county health department permit and a licensed well contractor. Confirm which water management district covers your parcel.
- Several electric utilities serve the county. Find yours before you buy land, then ask for a written cost to bring power to the barn site.
- Well, trenching and service connection are often outside the barn quote. Make builders say so in writing.

Almost every guide on this site says to "ask about water and electric" and moves on. Water and power for a horse barn in Marion County is where rural builds quietly gain cost and delay. This guide covers what to find out about the well, the power run and the layout, in what order. We are a referral service, not a builder, driller or electrician.
How much water does a horse barn really need?
Start with drinking water, then add everything else you will do with a hose. UF/IFAS Extension puts a normal healthy horse at roughly 5 to 15 gallons a day, more in heat and work. The table multiplies that range by herd size.
| Horses | Low (5 gal) | High (15 gal) |
|---|---|---|
| 4 | 20 gallons | 60 gallons |
| 10 | 50 gallons | 150 gallons |
| 20 | 100 gallons | 300 gallons |
Arithmetic on the UF/IFAS 5 to 15 gallon range, drinking water only. Wash racks, hosing, fire sprinklers and any pasture irrigation come on top.
Why peak matters. A well that covers the daily average can still run dry or lose pressure when you fill troughs and run a wash rack at the same time in July. Ask the driller about flow rate and storage, not just depth.
Well, county water or a tank: which fits?
Private well
- Independent of a utility line
- Needs a permit and a licensed driller
- Distance rules from manure, septic and wells nearby
Best if: no water main reaches the parcel.
Utility connection
- No well to drill or maintain
- Tap and line costs depend on distance
- May be required in some areas
Best if: a main already runs near your lot line.
Florida rules restrict new potable wells in "delineated areas" where an available water system line is close to the property (Rule 62-524.700, F.A.C.). Ask the county whether your parcel is in one.
Getting a well permitted in Marion County
- Ask which district covers your parcel
Marion County sits in the St. Johns River Water Management District, and a Southwest Florida Water Management District agreement with the health department also covers the county. The parcel decides.
- Hire a licensed water well contractor
In Florida the licensed contractor applies for the construction permit. Ask for their license number and check it.
- Check whether a water use permit applies
Household use is generally exempt. Irrigation or heavy livestock use can need a water use permit from the district, which can come before the well permit. Confirm with the district.
- Site the well first
Put it before the barn, septic and manure area. The state's equine manual sets distances; see manure management in Marion County.
- Test the water
Have a lab test the finished well. The Marion County Health Department can point you to testing.
Watch out: the farm-building exemption in Florida Statute 604.50 covers building codes and county fees for the barn. It does not obviously cover well rules or your utility's requirements. See Marion County horse barn permits.
Which electric utility serves your parcel?
Marion County is not one service territory. Public Service Commission filings show territorial agreements between the City of Ocala's electric utility and Duke Energy Florida, and between Ocala and Clay Electric Cooperative. Other cooperatives may serve parts of the county. A bill from the property, or the seller, answers it fast.
| Question for the utility | Why it matters |
|---|---|
| Is single-phase or three-phase available at the barn site? | Big pumps, arena lights and some equipment need more than standard service. |
| How far is the nearest line, and who pays for the extension? | Distance drives cost, and policies differ by utility. |
| How long from application to energized? | Power can hold up move-in after the barn is finished. |
| Is a separate meter needed for the barn? | Affects billing, and a barn apartment changes the answer. |
We found no published Marion County price for a power extension. Get a written estimate from your utility.
What the builder should put in writing
- Is the electrical service, panel and trenching from the pole or meter to the barn in the price?
- Who applies to the utility, and who pays any extension charge?
- Are water lines, frost-free hydrants, wash rack plumbing and hot water included?
- Where are the well and any septic relative to the barn and manure area?
- Is wiring in conduit, with a master shutoff? See horse barn fire safety.
- Does a sprinkler plan need a larger supply or a storage tank?
Saves money: have every builder price site utilities as separate lines in the quote comparison worksheet, so a low bid is not simply a bid that left out the power run.
Utilities also shape the budget: our horse barn cost guide lists well and utility connections among the items outside typical barn prices. To compare builders, describe your parcel in the form below. Independent local builders may reach out.

Frequently asked questions
Do I need a permit to drill a well for my horse barn in Marion County?
Generally yes. The St. Johns River Water Management District lists Marion among the counties where it has delegated well permitting to the county health department, and a Southwest Florida Water Management District agreement with the Florida Department of Health also covers Marion County, so the district depends on your parcel. Florida requires a licensed water well contractor. Confirm the district, fees and any water use permit with the Marion County health department before drilling.
Does the farm-building exemption cover my barn's electrical and well work?
Do not assume so. Florida Statute 604.50 exempts qualifying nonresidential farm buildings from the Florida Building Code and county or city codes and fees, but it does not say it removes state well rules or a utility's own service requirements. Ask the county and your electric utility separately.
Who provides electric service to rural Marion County?
More than one utility. Public filings show a territorial agreement between the City of Ocala (Ocala Electric Utility) and Duke Energy Florida, and another between Ocala and Clay Electric Cooperative. Other cooperatives may serve some areas. The power bill on your parcel, or the seller's, names the provider; confirm before you buy land.
How much water does a barn use?
UF/IFAS Extension puts a normal healthy horse at roughly 5 to 15 gallons a day depending on heat, humidity and activity. That is drinking water only. Hosing, wash racks and fire sprinklers add to it, so size the well or tank for peak demand, not the average.
