Should I Use Well Water or City Water for Irrigation in Florida?

Short answer:

For most Northeast Florida properties over a quarter acre with regular irrigation needs, a dedicated irrigation well is the better long-term choice. Installation payback is typically three to seven years through avoided city water charges, and a deep well provides iron-free water without staining. Small lots and seasonal properties may still be better on city water.

When a dedicated irrigation well makes sense

  • Property is a quarter acre or larger with grass and landscape beds that need regular watering.
  • Household is on a metered city water rate that charges tiered pricing for outdoor use.
  • Water restrictions in your municipality allow well irrigation on more days than city water use.
  • You plan to be in the home longer than the payback period (typically 3 to 7 years).

When city water is the right call

  • Small lot with modest irrigation needs where the well cost cannot pay back.
  • Seasonal or short-term property.
  • Deed restrictions or HOA rules that prohibit a well on the parcel.

The iron staining question

The most common concern homeowners raise about irrigation wells is staining. Shallow wells in this region often carry iron content that leaves reddish-brown stains on driveways, sidewalks, stucco, and vinyl fencing. Deep wells that reach the Floridan aquifer produce iron-free water and do not cause that problem. WaterCare tests iron content during the site survey and recommends the correct depth to avoid staining. See our residential irrigation service page and residential well and pump page for how the two systems work together.

Frequently asked questions

Is a dedicated irrigation well cheaper than city water? +
For most Northeast Florida properties over a quarter acre with regular irrigation needs, a dedicated irrigation well pays back the installation cost in three to seven years through avoided city water charges. Smaller lots or seasonal-use properties often do not justify the up-front cost.
Can I water my lawn with well water and drink city water? +
Yes. This is a very common setup in our service area. The irrigation well operates as a separate system with its own pump and controller, while household water continues to come from city supply, keeping the plumbing systems fully independent.
Will an irrigation well stain my house or driveway? +
It can, if it draws from a shallow iron-rich aquifer. Deeper wells that reach the Floridan aquifer produce iron-free water that does not stain surfaces. WaterCare evaluates iron content during the site survey and recommends the right depth.
Do I need a permit for an irrigation-only well? +
Yes. All new wells in Northeast Florida, including irrigation-only wells, require a permit from the applicable water management district. WaterCare handles permitting as part of the drilling process.
