Gwinnett Water Bill High in 2026? Leak Check, Meter Test, Adjustment and Lower-Bill Steps
A sudden high Gwinnett water bill usually has a reason: a silent toilet leak, outdoor irrigation, a service-line leak, new sod, pool filling, extra household use, or a billing/usage period change. This guide shows how to check the meter, test toilets, find hidden leaks, request a leak adjustment, contact Gwinnett Water Resources, and reduce your next bill without guessing.

Why Your Gwinnett Water Bill May Be Higher Than Normal
A high bill should be handled like a small investigation. First compare usage, then check for leaks, then review outdoor watering or one-time water use. Do not only compare the dollar amount, because sewer charges, stormwater charges, base charges, tiers, and usage can all affect the final bill.
Gwinnett County’s Customer Care FAQ lists several reasons consumption may increase between billing dates, including more guests in the home, landscaping or new sod, planting grass or shrubs, pressure washing, and even minor plumbing repairs. The County also says leaks are a common reason for unusually high usage.
Most likely: toilet leak
A silent toilet leak can waste a surprising amount of water without making obvious noise. Start here before assuming the meter is wrong.
Outdoor use adds up
New sod, irrigation, garden watering, pool filling, and pressure washing can make one billing cycle much higher.
Check gallons, not only dollars
Open your bill or online account and compare consumption with older months. A usage jump is the strongest clue.
| High Bill Clue | What It Usually Means | What to Check First |
|---|---|---|
| Usage suddenly doubled or tripled | A leak, irrigation issue, toilet problem, pool fill, or unusually high household use. | Run the 2-hour meter test and toilet dye test. |
| Bill increased slowly for 2–3 months | Small leak, irrigation schedule, seasonal outdoor use, or occupancy change. | Compare usage history and inspect toilets/faucets/yard. |
| Water bill high after yard work | New sod, landscaping, pressure washing, or irrigation repairs. | Check outdoor watering dates and any qualifying adjustment option. |
| Wet spot or soft ground in yard | Possible underground leak on private side or near service line. | Call a plumber if on private property; call dispatch if leak is in meter box/street. |
Gwinnett Water Leak Check: The 2-Hour Meter Test
Gwinnett County’s leak detection guidance gives a simple home test. The goal is to find out whether water is moving through the meter when nobody is using water inside or outside the home.
1
Turn off water-using activity
Do not use sinks, showers, toilets, dishwasher, washer, ice maker or outdoor water.
▾
Tell everyone in the home not to use water for two hours. Do not shut off the main supply for this test. You want the water system on, but no water being used.
2
Locate the water meter
It is usually in the front yard under a metal cover.
▾
Carefully remove the cover and look at the meter. Take a clear photo of the number shown on the readout. Also watch the small leak indicator wheel and needle.
3
Wait two hours and check again
No water should be used during this time.
▾
After two hours, read the meter again. If the number changed, or if the leak indicator moved while no water was being used, there is probably a leak.
4
Find whether the leak is inside, outside, or near the meter
Responsibility depends on location.
▾
Check toilets, faucets, showerheads, pipes under sinks, the water heater area, basement or crawlspace pipes, irrigation lines, and wet yard areas. If the leak is between your home and the meter, Gwinnett says it is generally on private property and must be repaired by the customer.
Silent Toilet Leaks: The Most Common High-Bill Problem to Check
A toilet leak can be quiet, constant, and expensive. Gwinnett’s leak detection page says to use food coloring or dye tablets in the toilet tank and wait without flushing. If color appears in the bowl, water is leaking from the tank into the bowl.
Simple dye test
Put food coloring or a dye tablet in the toilet tank, wait about 30 minutes, and do not flush.
Color in bowl = leak
If the bowl water changes color, the tank is leaking into the bowl and wasting water.
Common cause
Gwinnett says the cause is often a faulty toilet flapper, which is usually inexpensive to replace.
Constant running is serious
A constantly running toilet can waste a large amount of water every day and should be repaired quickly.
| Toilet Symptom | Likely Issue | Practical Fix |
|---|---|---|
| Color appears in bowl after dye test | Flapper or flush valve seal leak. | Replace flapper or related tank part; keep receipt. |
| Toilet runs every few minutes | Tank water is dropping and refilling. | Check flapper, chain, fill valve and overflow tube. |
| Water level too high | Water may be draining into overflow tube. | Adjust fill valve or float; replace faulty parts. |
| Multiple old toilets | Higher baseline water use and possible slow leaks. | Test every toilet and consider efficient replacements where useful. |
Outdoor Water Use That Can Make a Gwinnett Bill Look High
Not every high bill is a hidden leak. Outdoor water use can be enough to push a bill into a higher usage pattern, especially during warm months, new landscaping, new sod installation, irrigation system problems, or pressure washing.
Irrigation schedule
A sprinkler system running too long, too often, or at the wrong time can increase usage quickly.
New sod or landscaping
New grass, shrubs, flowers and landscaping can require extra water during establishment.
Pool or pressure washing
Pool filling, pressure washing a driveway, or outdoor cleaning can create a one-cycle spike.
How to Request a Gwinnett Water Bill Leak Adjustment
If you found and repaired a qualifying leak, do not stop at the repair. Gwinnett’s leak adjustment form gives specific rules, deadlines and submission routes. The form also makes clear that completing the request does not guarantee approval.

The request must be made within 3 months of a leak repair, qualifying pool fill, or qualifying new sod installation.

Proof of repair must be included. Keep plumber invoices, parts receipts, repair photos and repair date.

Pay while review is pending
The form says customers remain responsible for payment until the request is granted, denied, or other arrangements are made.
| Leak Adjustment Item | What Gwinnett Asks For | Practical Tip |

1
Repair the leak first
An adjustment request is stronger after the leak is fixed.

Fix the leak and collect proof. For professional repair, keep the plumber invoice. For DIY repair, keep store receipts, photos of parts, and before/after notes.
2
Record the meter after repair
The form asks for a meter reading after repair.
▾
Take a clear photo of the meter after the repair. If the leak indicator no longer moves when no water is being used, write that down in your notes.
3
Submit the leak adjustment form
Do not miss the 3-month request window.
▾
Complete the official leak adjustment request form and submit it with proof. The form says review may take 2–3 business days, and incomplete forms can delay the process.
How to Lower Your Gwinnett Water Bill After a High-Bill Month
Once the emergency is handled, the next goal is to lower future usage. Some changes are simple, like fixing toilets and faucets. Others require behavior changes, irrigation adjustments, or efficient fixtures.
| Action | Why It Helps | How to Do It Practically |
|---|---|---|
| Test every toilet | Silent toilet leaks are common and can run continuously. | Use dye tablets or food coloring once per month after a high bill. |
| Check irrigation zones | Broken heads and overwatering can waste large amounts outdoors. | Run each zone briefly and look for runoff, misting, pooling or broken heads. |
| Run full loads | Dishwashers and washing machines waste less when full. | Wait until a full load whenever possible. |
| Shorten showers | Showers are a repeat daily use point. | Use a timer and install efficient showerheads where useful. |
| Use WaterSense fixtures | Efficient toilets, showerheads and aerators lower baseline use. | Replace old fixtures when repairing leaks or remodeling. |
| Monitor monthly usage | A second spike can be caught earlier. | Review online account history and compare to the same season last year if available. |
Request free conservation kits
Gwinnett says leak detection kits and low-flow home retrofit kits are available on request at the Customer Care counter.
Watch outdoor watering rules
When drought restrictions apply, follow Gwinnett’s allowed watering days and times to reduce waste and avoid unnecessary use.
Use the online bill history
Compare usage month by month. This helps separate one-time use from ongoing leaks.
Fix small leaks quickly
A small drip or toilet leak can become a large bill if it continues through a full billing cycle.
