Why Your New Orleans Water Bill Is Suddenly Sky High (and How to Fix It)
Your water bill just jumped 300% and you have no idea why. The first thing you should know is that New Orleans homes are uniquely vulnerable to hidden plumbing problems. Between our shifting clay soil, aging cast iron pipes, and the Sewerage and Water Board of New Orleans (SWBNO) billing quirks, a sudden spike often signals a leak you cannot see. This guide walks you through exactly what to check before you call a plumber, and what to do if the city’s meter is the culprit. Who to Call for a 24 Hour Emergency Plumber in New Orleans.
Understanding Your New Orleans Water Bill
New Orleans water rates are among the highest in the country, and the SWBNO uses a tiered system where the more you use, the more you pay per gallon. Most homeowners see bills between $50 and $120 for a typical month. But when a leak starts, that number can double or triple in just 30 days.

SWBNO bills are based on actual meter readings most months, but they estimate every few cycles. If your bill suddenly spikes after an estimated read, the next actual read could show a huge catch-up charge. That is why the first step is always to verify the meter reading yourself.
Common Causes for Sudden Spikes
Before you panic about a broken pipe, check these three common culprits:
- A running toilet can waste 200 gallons per day. The flapper valve often fails silently.
- A dripping faucet may seem minor, but 10 drips per minute equals about 1 gallon per day.
- Underground slab leaks caused by soil subsidence can leak thousands of gallons before you notice any surface signs.
In New Orleans, slab leaks are especially common in mid-century ranch homes built on shifting clay soil. The ground moves, pipes crack, and water escapes beneath your concrete slab. You will not see it, but your meter will spin 24/7. Fixing Slab Leaks and Foundation Plumbing in Your Garden District Home.
The 15-Minute DIY Leak Test
Before you call a plumber, you can confirm whether water is moving through your meter. Here is how: Fast Water Heater Repair and Replacement Services for Metairie Residents.
- Locate Your Meter
Most New Orleans homes have the meter in the front yard near the street, inside a concrete or plastic box.
- Turn Off All Water
Shut off every faucet, toilet, and appliance. Make sure no one is running water anywhere in the house.. Read more about Tankless or Traditional Water Heaters — Which One Actually Makes Sense for a Harvey Family?.
- Check the Low-Flow Indicator
Look at the small triangle or wheel on the meter face. If it is spinning, water is still flowing.
- Record the Numbers
Write down the digits on the meter. Wait 15 minutes without using any water. Check again. If the numbers changed, you have a leak.
Pro Tip: If the low-flow indicator is moving but you cannot find any obvious leaks, the problem is likely underground or in a wall. That is when you need professional leak detection equipment.
How to Dispute a Bill with SWBNO
If your meter test shows no leak but your bill is still high, the issue may be with SWBNO’s reading or an administrative error. Here is the process:
- Call Customer Service
Phone: (504) 529-2837. Have your account number and the current meter reading ready.
- Request a Re-Read
If the bill was based on an estimate, ask for an actual read. SWBNO will send a technician within 3 business days.
- File a Leak Adjustment Request
If you had a confirmed leak and repaired it, you can apply for a water loss credit. You will need a plumber’s invoice showing the date and location of the repair.
The SWBNO Leak Adjustment Policy allows a one-time credit for up to 50% of the excess usage caused by a leak, but only if you provide proof of repair. Without a licensed plumber’s statement, they will deny the credit.
When to Call a Professional Plumber
You should call a plumber immediately if:
- Your meter spins constantly even with all water off.
- You hear running water when no fixtures are on.
- Your water pressure drops suddenly.
- You see damp spots on floors or baseboards with no obvious source.
Professional leak detection uses acoustic sensors and thermal imaging to pinpoint leaks without tearing open walls. In New Orleans, where many homes have slab foundations, this non-invasive approach saves thousands in repair costs..

Frequently Asked Questions
How much water does a running toilet waste?
A single leaking toilet can waste 200 gallons per day, which equals about 6,000 gallons per month. At New Orleans rates, that is roughly $100 in extra charges.
Can I get a credit for a leak if I fix it myself?
No. SWBNO requires a licensed plumber’s invoice showing the date and location of the repair. DIY fixes do not qualify for the leak adjustment credit.
How long does it take to get a leak adjustment credit?
Processing takes 30 to 45 days after you submit the complete paperwork. You must include the plumber’s statement, repair date, and a copy of the high bill.
What if my bill is high but the meter shows no leak?
Call SWBNO customer service at (504) 529-2837. They can verify the reading and check for administrative errors or estimated billing issues.
Should I turn off my water if I suspect a major leak?
Yes. Locate your main shut-off valve, usually near the water meter, and turn it clockwise. This stops further damage and waste until a plumber arrives.
