How This Works: Drips to Gallons to Dollars
The calculator converts drips to gallons with the U.S. Geological Survey's drip size: 1/4 milliliter, or 15,140 drips per gallon. A day has 1,440 minutes, so drips a minute × 1,440 ÷ 15,140 gives gallons a day.
Toilets use published flow figures instead of drips. EPA WaterSense puts an audibly running toilet at 200 gallons or more a day; a utility leak table from Kirkland, Washington puts a slower toilet leak at about 1 gallon an hour, or 24 gallons a day.
Worked examples at 2026 City of Grand Rapids rates: $2.74 water + $4.29 sewer = $7.03 per 748 gallons ($9.40 per 1,000 gallons).
| Leak | Gallons a day | Gallons a year | Units (748 gal) | Cost a year |
|---|---|---|---|---|
| Faucet, 1 drip a second (86,400 drips a day) | 5.7 | 2,083 | 2.78 | $19.58 |
| Showerhead, 10 drips a minute | 0.95 | 347 | 0.46 | $3.26 |
| Toilet, slow leak (1 gallon an hour) | 24 | 8,760 | 11.71 | $82.33 |
| Toilet, running (200 gallons a day) | 200 | 73,000 | 97.59 | $686.08 |
Drip size varies. EPA WaterSense puts one drip a second at more than 3,000 gallons a year and a showerhead dripping 10 times a minute at more than 500 gallons a year, both above the USGS-based results. The USGS states that no scientific definition of a drip exists, so the calculator's faucet and showerhead totals read as conservative.
Grand Rapids Water and Sewer Rates for 2026
The Grand Rapids City Commission approved these rates on December 16, 2025, effective January 1, 2026. The City bills water and sewer by the unit, also written HCF: 100 cubic feet, or 748 gallons.
Every extra unit a leak pushes through the meter adds the water charge and the sewer charge. The monthly service charge by meter size stays the same with or without a leak, so the calculator leaves it out.
| City of Grand Rapids retail bill | Water per unit | Sewer per unit | Combined per unit | Combined per 1,000 gal |
|---|---|---|---|---|
| Grand Rapids (inside the city) | $2.74 | $4.29 | $7.03 | $9.40 |
| Walker | $2.23 | $3.03 | $5.26 | $7.03 |
| Kentwood | $1.92 | $3.51 | $5.43 | $7.26 |
| Cascade Township | $2.67 | $3.46 | $6.13 | $8.20 |
| Grand Rapids Township | $2.42 | $2.86 | $5.28 | $7.06 |
Source: City of Grand Rapids 2025 Final Water/Sewer Rate Study, "Water & Sewer Rates for Grand Rapids & Retail Customer Communities," effective January 1, 2026. The study puts the typical Grand Rapids household at 21 units of water a quarter, about $101.76 for water and $113.61 for sewer.

Toilet Dye Test: Find a Silent Leak in 30 Minutes
A worn flapper lets tank water slip into the bowl without a sound. The City of Grand Rapids Water Leak Detection Guide gives four steps; the City's WaterSense handout adds the flush afterward.
- 1Wait until the tank finishes refilling and the water is still.
- 2Add a few drops of food coloring to the tank.
- 3Leave the toilet unflushed.
- 4Check the bowl after 15–30 minutes. Color in the bowl means a leak, usually a worn flapper or a faulty overflow pipe.
- 5Flush afterward so the dye does not stain the bowl.
EPA WaterSense recommends checking the flapper and replacing it at least every five years, because the rubber wears out. A toilet that tests positive belongs in the calculator as a "silent leak."
Water Meter Leak Test: The Two-Hour Check
The meter test catches leaks no dye reaches: a supply line in a wall, a slab leak or a service line under the yard. The steps come from the EPA WaterSense handout the City of Grand Rapids publishes.
- 1Find the meter. In cold climates it usually sits inside, often in the basement.
- 2Turn off every faucet and water-using appliance, then write down the reading.
- 3Use no water for two hours: no flushing, no faucets, no ice maker cycle.
- 4Read the meter again. Any change means water is leaving the plumbing somewhere.
16 Units a Winter Month
EPA WaterSense treats winter use above 12,000 gallons (16 CCF) a month for a family of four as a sign of a serious leak.
Underground Leak Clues
The City of Grand Rapids lists low water pressure, sinkholes or potholes, and unexplained jumps in water use as signs of a service line leak.

Gallons that passed in two hours × 12 gives gallons a day. Enter it under "Other leak" to price it.
After the Repair: Leak Credits and Fix a Leak Week
A City of Grand Rapids account gets part of a leak back through the Residential Leak Adjustment Program in §3.3 of the 2026 Water System Rules. The City bears up to 25% of the water usage on the highest quarterly bill; the customer pays the other 75%.
- Applies to single-occupancy residential customers, once every 24 months.
- Requires use during the leak above three times the same quarter last year.
- Excludes sewer charges, so most of a leak's cost stays on the bill.
- Starts with a pre-screen online or at 311 / 616-456-3000.

A leak that shows on the meter but not at any fixture points to hidden pipe; the leak detection and repair page covers how hidden leaks get located.
Common Questions
How much does a dripping faucet add to a Grand Rapids water bill?
A faucet dripping once a second adds about $19.58 a year at 2026 Grand Rapids rates. At the USGS drip size, 86,400 drips a day equal about 5.7 gallons, or 2,083 gallons a year. That is 2.78 billing units of 748 gallons, and each unit costs $2.74 for water plus $4.29 for sewer.
Why does the calculator show fewer gallons than EPA's 3,000 gallons for one drip a second?
Drip size changes the total. The calculator uses the U.S. Geological Survey's 1/4-milliliter drip, or 15,140 drips per gallon, which gives about 2,083 gallons a year. EPA WaterSense puts the same faucet at more than 3,000 gallons a year, which implies a larger drip. The USGS notes that no scientific definition of a drip exists, so treat the result as a floor, not a ceiling.
Does Grand Rapids charge sewer on water that leaks?
The City bills sewer by the unit, and its Residential Leak Adjustment Program never adjusts the sewer charge. In 2026 the city sewer charge is $4.29 a unit, higher than the $2.74 water charge, so sewer makes up about 61% of the calculator's cost. The calculator assumes leaked water is billed for sewer too; your bill shows the units actually charged.
My water comes from Wyoming, Plainfield Township or my own city. Can I still use the calculator?
Yes. Choose "My own rate" and type the water and sewer volume charges from your bill, added together, per 1,000 gallons or per 100 cubic feet. The calculator lists Grand Rapids retail rates only because those are the rates verified from an official schedule for this page.
How long does a toilet dye test take?
The City of Grand Rapids says to check the bowl 15 to 30 minutes after adding food coloring to a still tank; EPA WaterSense says color in the bowl after 10 minutes means a leak. Waiting the full 30 minutes catches slower leaks.
Sources and How This Tool Works
Gallons a day = drips a minute × 1,440 minutes ÷ 15,140 drips per gallon (USGS drip size of 1/4 milliliter), or the EPA WaterSense figure of 200 gallons a day for a running toilet, or about 1 gallon an hour for a slow toilet leak (City of Kirkland, WA utility table). Yearly gallons = gallons a day × 365. Yearly cost = yearly gallons × the water plus sewer volume charge, with Grand Rapids rates from the City's 2025 Final Water/Sewer Rate Study (effective January 1, 2026), billed per unit of 100 cubic feet (748 gallons).
