Why Is My Water Bill So High?

This is the part most people missed. Bartlett didn't just raise rates — it moved residential customers to a tiered conservation structure, per the village's official water & sewer page. The old minimum bill is gone, replaced by a $15.47 monthly base charge (standard 5/8-inch meter) plus usage priced in three tiers:

Do the math on a typical family using 6,000 gallons a month: the first 3,000 gallons cost about $29.25, the next 3,000 about $39 — $68.25 in water charges before the $15.47 base charge and sewer. Push past 6,000 gallons — easy in a summer with a lawn to water — and every additional thousand gallons costs $15.75. That's the tier the village wants you to notice.

Sewer is its own maze, because it depends on your county: Cook County residents pay about $3.12 per 1,000 gallons (plus an $8.78 meter charge), DuPage about $5.04 (plus $18.81), and Kane about $2.28 (plus $2.11). Cook looks cheaper on the water bill only because part of wastewater treatment shows up separately on your property tax bill via the Metropolitan Water Reclamation District.

Two things worth knowing: seniors 65 and older get a 10% discount on the water-sewer bill — call the water department at 630-837-0800 if you're eligible and not getting it. And in early 2026 the village launched a consumer water portal (bartlettil.my360-app.com) where you can watch your usage in near-real time, set a water budget, and get leak alerts — genuinely useful if your bill surprised you.

Elgin's 2026 budget — which also carried the city's first property tax increase in 11 years — includes a 9% water rate increase and a 4% sewer rate increase, explicitly tied to a long-term plan to fund water and sewer improvements. City officials blamed inflationary pressures and rising capital costs.

An Elgin water bill has a lot of line items, per the city's official billing page: a $6.11-per-100-cubic-feet water charge (about $8.17 per 1,000 gallons), a $1.95 sewer maintenance charge, a $15.44 monthly water availability charge, plus Fox River Water Reclamation District charges ($6.76 monthly availability plus $2.44 per 100 cubic feet for treatment) — and the $25.95 refuse fee rides along on the same bill, which is why the total always looks bigger than "water" alone.

1. The pipes are old, and replacing them never stops. Bartlett's rate study concluded the village must replace 1% of its watermains every year — forever — and put $1.1 million a year into sewer maintenance. That's the unglamorous core of your bill: a century of buried infrastructure being rebuilt one percent at a time. DuPage County's own 2026 rate notice said the same thing — a rate study every four years, with "aging infrastructure" as the named reason for increases.

2. The lead pipe mandate. Illinois has more lead service lines than any other state — over 636,000 of them. The state's Lead Service Line Replacement and Notification Act (effective January 2022) requires every community water system to inventory its lead lines and file a replacement plan with the Illinois EPA, with final plans due April 2027. Federal rules separately demand full replacement within roughly a decade. The estimated statewide cost runs into the billions, and while state and federal loans cover part of it, the funding gap is exactly the kind of thing that lands on ratepayers over time. If your home was built before the mid-1980s, your service line might be part of this story.

3. The water itself costs more. Bartlett buys Lake Michigan water through the DuPage Water Commission, and village documents note that rate adjustments have had to account for rising supply costs from Chicago and the Commission. Lake Michigan water is excellent — but it's purchased, treated, and pumped, and none of that gets cheaper.

One thing that's not driving your bill: data centers. We looked into whether data centers could raise water bills and found the system is designed so big new users pay their own connection and capacity fees. Your bill is about your town's pipes, not someone else's servers.

• Hunt the leak first. The EPA says 5 to 10 percent of U.S. homes have easy-to-fix leaks wasting 90 gallons a day or more — that's nearly 3,000 gallons a month, enough to shove a Bartlett household into the expensive tier. Check your meter before and after two hours of no water use; if it moved, something's leaking. For toilets, put food coloring in the tank — color in the bowl within 15 minutes means the flapper is shot.
• Know your tier. In Bartlett, the price jumps from $9.75 to $13.00 per thousand gallons at 3,001 gallons, and to $15.75 past 6,000. The average American family uses 300+ gallons a day — about 9,000 a month — which means a typical family is buying its last gallons at the top tier. Lawns are usually what push households over; every sprinkler cycle is top-tier water.
• Use the village's water portal. Bartlett's my360 portal (bartlettil.my360-app.com) shows your usage with charts, lets you set a water budget with threshold alerts, and can flag possible leaks while you're out of town. If your bill spiked and you don't know why, this is step one.
• Claim the senior discount. Bartlett residents 65+ get 10% off the water-sewer bill. It's not automatic — call 630-837-0800.
• Upgrade the thirsty fixtures. Bathrooms are more than half of indoor water use. EPA WaterSense-labeled toilets use 1.28 gallons per flush versus 3.5+ for older ones, and the EPA estimates a family can save $380+ a year on water costs with efficient fixtures and appliances.
• Check your service line material. Under Illinois law, your water utility had to notify you if your service line is lead, galvanized needing replacement, or unknown material. If you got that letter, ask the village what the replacement timeline is for your street — and whether there's any cost to you.
