DFW Water & Sewer Rate Increases by City (2026): Rate Hike or Hidden Leak?

DFW water and sewer rates are rising city by city in 2026, mostly driven by wholesale costs from the North Texas Municipal Water District - Arlington raised rates 6.3% (about $5.10 more per month for a typical household) effective October 1, 2026, McKinney and Frisco each approved 9% increases, Plano raised rates in October 2025 to cover an 8% NTMWD wholesale hike, and Dallas and Fort Worth both published new tiered rate schedules - but if your bill jumped well beyond your city's published percentage, that gap usually points to a hidden leak, not a rate increase.

Decision guide

How to decide what happens next

Start by identifying whether the issue is isolated to one fixture or affects several drains. If the problem is spreading, includes dirty water, or risks property damage, treat it as urgent and request provider guidance.

DFW water and sewer rate increases by city: what actually changed in 2026

Most of these increases trace back to the same source - rising wholesale water costs from the North Texas Municipal Water District (NTMWD) - but each city sets its own final rates and effective date.

Dallas: new rates took effect October 1, 2025 - the monthly service charge is now $5.39 for water and $8.59 for sewer, with tiered volume charges from $2.17 per 1,000 gallons for the first 4,000 gallons up to $13.20 per 1,000 gallons above 30,000 gallons, plus a $6.19-per-1,000-gallon sewer volume charge.
Fort Worth: current rates run $2.28 to $5.37 per CCF (748 gallons) for water plus $4.30 per CCF for sewer and a $21.65 monthly base charge; the City Council approved further increases (the top tier rising to $5.60/CCF and the base charge to $14.45) effective January 1, 2027.
Arlington: new rates took effect October 1, 2026 - a 6.3% average residential increase, roughly $5.10 more per month for a typical household using 8,000 gallons of water and 4,000 gallons of wastewater, approved by City Council on September 15, 2026 to cover rising raw-water, wastewater-treatment, and system-repair costs.
Plano: raised rates starting October 2025 to offset an 8% wholesale water rate increase from NTMWD, plus an average $1.50 increase to drainage fees, with the city phasing in further increases over the next three years.
McKinney and Frisco: both approved 9% residential rate increases tied to the same NTMWD wholesale cost pass-through affecting the wider North Texas region.

Verification

How to tell a rate increase from a hidden leak on your own bill

Compare your city's published percentage increase above to your own bill's percentage jump - a rate increase raises bills by roughly the same percentage across the board, not by a random spike on one account.
Check your water meter's leak indicator with every fixture off before assuming a bill jump is only the new rate - see our step-by-step meter-check guide.
A rate increase changes the price per gallon, not how many gallons you used - if your metered usage also jumped, that points to a usage or leak question, not a rate question.
Ask your city utility's billing department to break down how much of your bill's dollar increase came from the published rate change versus increased consumption.

Common questions

What is the quick decision?

When should I call instead of waiting?

Call when water damage, wastewater, essential fixture loss, or repeated backup symptoms are present.

What should I do first during a plumbing emergency?

Stop the water source if safe, avoid using affected fixtures, protect people from contaminated water, and request help.

What should I do during an active leak?

Use the closest working shutoff valve, keep water away from electrical areas, and request leak help quickly if water keeps spreading.

When should a drain backup be treated as urgent?

Treat it as urgent when more than one fixture backs up, wastewater appears, or the problem blocks essential use.

Which sewer symptoms need fast attention?

Multiple slow drains, sewer odor, toilet gurgling, dirty tub water, or outdoor cleanout overflow should be treated as urgent warning signs.

When does fixture loss become urgent?

No usable toilet, no hot water for vulnerable occupants, or water near unsafe areas can justify urgent guidance.

Can I use chemical drain cleaner during a backup?

Avoid chemical cleaners once water has backed up. They can create splash risk and may not solve a deeper blockage.
