Lake County is Orlando's lake-country northwest — Clermont, Groveland, Eustis, and Umatilla. USGS describes two sand ridges running through the county, the Lake Wales Ridge and the Mount Dora Ridge, and lists Sugarloaf Mountain (312 feet) west of Lake Apopka as the highest point in peninsular Florida. Many freeze-killed citrus groves have given way to development, and the Floridan aquifer system is the county's major groundwater source, so new household wells and irrigation wells remain a routine part of building here.
From the Clermont-Groveland growth belt to the rural north around Umatilla, Lake County requests cover new wells, pump work, and water treatment. Depth and casing change between the ridge tops and the lake-filled valleys — local well logs are the dependable guide.
Lake County Service Details
What providers in this area actually see: coverage, common jobs, local pricing factors, and rules worth knowing.
Service Area Notes
- Coverage across Clermont, Groveland, Eustis, Umatilla, Mount Dora's rural fringe, Astatula, and the county's sand-ridge acreage.
- Former grove tracts being built on are core new-well territory; for irrigation wells serving nurseries, groves, or large lawns, state the flow you need in the request.
- Lake County is split between two water management districts. In the St. Johns River district area, the Florida Department of Health in Lake County (DOH-Lake) issues permits for wells under 6 inches in diameter; in the southwest of the county, the Southwest Florida Water Management District permits wells. The contractor typically files the permit.
Common Jobs in Lake County
- New Floridan aquifer wells for homesites on former grove land
- Irrigation wells for groves, nurseries, and large lawns
- Pump and pressure tank replacement on aging rural systems
- Hardness and sulfur-odor treatment matched to a water test
- Well inspections for the county's active land and homesite market
- Pressure and low-flow troubleshooting on older wells
What Drives Pricing Here
- On the ridges, USGS reports up to 200 feet or more of surface sands and water tables more than 100 feet down, so casing length drives the quote as much as total depth; in the lake-filled Central Valley, shallow groundwater sits near the surface
- Sand-ridge terrain and elevation changes can affect drilling and rig access lot to lot
- Irrigation-yield requirements on grove and lawn wells drive bore diameter and pump sizing
- USGS finds most Upper Floridan water here is calcium- or calcium-magnesium-bicarbonate (the minerals behind hard water), so softening is a common add; sulfur treatment depends on your test
Permits & Local Rules
- Florida law requires water well contractors to be licensed by a water management district (s. 373.323, F.S.). In the St. Johns River district part of Lake County, DOH-Lake issues permits for wells under 6 inches in diameter; in the southwest, the Southwest Florida Water Management District permits wells. DOH-Lake says an approved permit is valid for one year, and the well completion report must be filed before a certificate of occupancy is released.
- State rule requires a septic system to sit at least 75 feet from a private potable well (Rule 62-6.005, F.A.C.). DOH-Lake notes that some ordinances and deed restrictions require connection to available public water instead of a well. Questions: DOH-Lake environmental health, 352-253-6130.
- Parts of Lake County are state-designated 'delineated areas' with known groundwater contamination — statewide, most were delineated for ethylene dibromide (EDB) — where new drinking-water wells face extra construction and testing rules (Chapter 62-524, F.A.C.). SJRWMD lists Lake among the counties where it permits those wells directly.
Geology & Water Table Notes
- USGS calls the Floridan aquifer system the major source of ground water in Lake County. On the ridges the water table can be more than 100 feet down, while the lake-filled Central Valley has groundwater at or near the surface — so depth and casing can change over short distances.
- USGS found most Upper Floridan water in the area is calcium-bicarbonate or calcium-magnesium-bicarbonate (hard water), with sodium, chloride, and sulfate more dominant near the St. Johns and Wekiva rivers. Sulfur odor can turn up in Florida wells — test before choosing treatment.
- DOH-Lake's water program samples for pesticide contamination in old grove and agricultural areas — worth asking about before drilling a drinking-water well on former citrus land.

Pick the emergency option if a Lake County pump has quit. Callback speed is up to whichever providers are free, and it helps to say whether a storm or outage came first.
Lake County FAQs
We bought old citrus acreage. Do we need a new well or can we reuse the grove well?
Have any existing grove or irrigation well inspected and tested before you count on it for the house — older ag wells may not meet current construction standards for drinking-water wells. Ask whether the parcel is in a state-delineated contamination area; DOH-Lake also samples for pesticides in old grove areas. If the old well isn't suitable, a local contractor can advise whether to keep it for irrigation and drill a separate household well.
Is the sulfur smell in my Lake County well water harmful?
The rotten-egg smell comes from hydrogen sulfide gas, which can occur naturally in Florida wells. It's unpleasant and corrodes fixtures, and the smell alone doesn't tell you whether the water is safe — so test for bacteria too. Aeration or an oxidizing filter clears it; test first so the treatment matches the actual level.
Who issues well permits in Lake County?
It depends on where you are. In the St. Johns River Water Management District part of the county, the Florida Department of Health in Lake County issues permits for wells under 6 inches in diameter; in the southwest, the Southwest Florida Water Management District issues them. Either way the well must be built by a Florida-licensed water well contractor, and DOH-Lake requires the completion report before a certificate of occupancy is released.
Why is Lake County hillier than the rest of Florida?
Two old sand ridges — the Lake Wales Ridge and the Mount Dora Ridge — run through the county, and USGS lists Sugarloaf Mountain (312 feet) as the highest point in peninsular Florida. For wells, those ridges can mean deep sand and a deep water table, which affects casing and cost.
