High Water Bill in Jupiter, FL: How to Find the Cause

Close every tap and appliance, find your meter, and watch the low-flow indicator for at least 15 minutes. If it keeps moving, water is escaping somewhere on your property. If it holds still, the extra usage is coming from fixtures, irrigation, or a change in how the house is used.

The next step is to separate inside from outside. Close the main shutoff at the house and look again. If the meter still moves, the leak is between the meter and the house. If it stops, the leak is inside.

In Jupiter, the water on your bill generally comes from the Town of Jupiter Utilities Department. Sewer service in Jupiter, Tequesta, and parts of Juno Beach and Jupiter Farms comes from the Loxahatchee River District, which bills quarterly. A higher water reading can therefore raise the sewer charge too, since the District uses water consumption as part of how it bills.

For non-residential customers, the District calculates sewer bills from a 12-month rolling average of water use. Homes on private wells, as in much of Jupiter Farms, have no Town water bill at all. Their warning sign is a pump that cycles constantly or an electric bill that rises.

A running toilet can waste 200 gallons or more a day. To test, add a few drops of food coloring to the tank, wait without flushing, and check the bowl. Color in the bowl means the flapper is leaking. The fix is usually inexpensive, and the toilet repair page explains the parts.

Irrigation is the other big one in Florida. A cracked line or a stuck valve can run for weeks, especially in summer when the system runs more. A soggy patch, unusually green grass, or a pressure drop at the sprinklers all point to a leak.

The Town of Jupiter's Utilities Department plans a system-wide upgrade to Advanced Metering Infrastructure, starting in spring 2026 and expected to finish in April 2028. According to the Town, the new meters will bring early leak detection, high-bill alerts, and near real-time usage data through an online portal and mobile app.

The upgrade schedule decides if your neighborhood has new meters yet. If it has, the portal can show when water was used, and a steady overnight flow is a strong sign of a leak. If not, the meter test still works.

A water meter keeps a running total, much like a car odometer. Write down the reading at the same time each day for a few days, and subtract each from the next to see daily use. If you know nothing was running overnight, the overnight difference should be near zero.

Compare your readings with the bill. If the meter total is higher than the last bill's reading and your habits have not changed, you are using more than before, and the next step is to find where.

In the dry months irrigation often runs more, and a pool that loses water to heat and wind adds to the draw. In summer, rain can cover a leak because lawns stay green without watering. Seasonal residents and guests change household use too, and a house that is empty for weeks should show almost no usage.

That last point is a useful test. If the house has been vacant and the meter still moves, water is escaping. A vacant house with a normal-looking bill is a stronger leak signal than an occupied one.

A plumber can narrow the leak without opening walls. Pressure tests on isolated lines show whether the hot side or the cold side is losing water, and listening and thermal tools pinpoint the spot. That saves time and avoids cutting in the wrong place.

If the leak is under the slab, the under-slab leak repair page explains the options. A leaking irrigation line or hose bib is usually a smaller repair, and a failing faucet is covered under faucet and sink repair.

If the leak is inside, leak detection traces it before any wall is opened. If it is between the meter and the house, water line repair covers the service line. Ask the Town's customer service whether any billing adjustment applies after a repair, since policies differ.

In Juno Beach, FL 33408, some addresses are served by Seacoast Utility Authority instead of the Town, so check your bill to see which utility to ask.
