What It Costs to Water a Lawn in Colorado Springs (Calculated From the Published Tariff)
Last updated: July 30, 2026
Quick answer: Colorado Springs Utilities bills water in tiered blocks per cubic foot, and lawn irrigation is what pushes a household up through them. On the Inside City residential schedule the commodity charge is $0.0578 per cubic foot for the first 999 cf, $0.0721 from 1,000 to 2,499 cf, and $0.1083 at 2,500 cf or greater — so the top block costs 1.87 times the first. Because the blocks apply to total household use, and indoor use fills the cheap block first, irrigation is charged mostly at the higher marginal rates. The practical consequence is that watering cost rises faster than lawn area: on the assumptions set out below, a 10,000 sq ft lawn costs roughly 15 times what a 1,000 sq ft lawn costs to irrigate — for ten times the grass.
The two inputs, both stated openly
Everything on this page is arithmetic on two things. Neither is estimated.
1. The published tariff. From the Colorado Springs Utilities Residential Rate Sheet, water schedule (WR), Inside City:
- Service charge, per meter, per day (5/8" to 1"): $0.8512 — about $25.54 over a 30-day month
- Commodity charge, first 999 cf: $0.0578 per cubic foot
- Commodity charge, 1,000 to 2,499 cf: $0.0721 per cubic foot
- Commodity charge, 2,500 cf or greater: $0.1083 per cubic foot
Outside City rates are higher — $0.0867, $0.1082 and $0.1625 per cubic foot for the same blocks, on a $1.2768 daily service charge. If you are outside the city limits, substitute those.
2. The unit conversion. A cubic foot of water spread one inch deep covers twelve square feet, so:
cubic feet = lawn area in square feet × depth in inches ÷ 12
One inch of water over 1,000 sq ft is therefore 83.33 cubic feet. That is geometry, not an estimate.
How much water does a lawn actually take?
At one inch per week — a common working figure for cool-season turf, and the one used throughout this page — monthly irrigation volume comes out as:
| Lawn area | Irrigation, cubic feet per month |
|---|---|
| 1,000 sq ft | 357 cf |
| 2,500 sq ft | 893 cf |
| 5,000 sq ft | 1,786 cf |
| 7,500 sq ft | 2,679 cf |
| 10,000 sq ft | 3,571 cf |
(Based on a 30-day month, which is 4.29 weeks.)
The tier trap: why the cost is not proportional
Here is the part that does not appear on a rate sheet. The blocks apply to your total metered use, not to irrigation separately. Indoor use — showers, laundry, dishes — already occupies the bottom of the first, cheapest block. Irrigation stacks on top of it, which means the lawn is billed at whatever block the household has already climbed into.
The table below models that. It assumes an indoor baseline of 600 cf per month; that figure is an assumption, not a measurement, and it is stated so you can replace it with your own winter usage, when irrigation is off and your bill shows indoor use alone.
| Lawn area | Irrigation cf | Total household cf | Marginal rate | Added cost per month |
|---|---|---|---|---|
| 1,000 sq ft | 357 | 957 | $0.0578 | $20.64 |
| 2,500 sq ft | 893 | 1,493 | $0.0721 | $58.67 |
| 5,000 sq ft | 1,786 | 2,386 | $0.0721 | $123.04 |
| 7,500 sq ft | 2,679 | 3,279 | $0.1083 | $215.64 |
| 10,000 sq ft | 3,571 | 4,171 | $0.1083 | $312.34 |
Ten times the lawn area, about fifteen times the irrigation cost. That gap is the tier structure doing its job — the blocks above the first exist, in Utilities’ own description, to discourage waste.
What this means in practice
Reducing turf area saves more than proportionally. Taking 2,500 sq ft out of a 7,500 sq ft lawn does not remove a third of the cost — it removes the most expensive third, because those cubic feet were being billed in the top block. This is the strongest financial argument for converting decorative turf, and it is a stronger argument the larger the lawn.
A leak is billed at your marginal rate, not the base rate. Any water lost to a broken head or a cracked lateral lands on top of everything else you have used, so it is charged at the highest block you reach. This is worth pairing with the rule: Colorado Springs Utilities requires leaking sprinkler systems to be repaired within 10 days. The rule and the bill point the same direction.
Overwatering is expensive at the margin. The last inch applied in a month costs nearly double the first, once a household is into the top block. Efficiency changes are worth more here than the average rate suggests.
2026 sharpens all of this. Utilities states that low snowpack, warmer-than-normal temperatures and faster snowmelt will reduce the amount of water flowing into its system by about half this year. See our Colorado Springs watering rules guide for the six Water Wise Rules currently in force.
How to run these numbers for your own property
- Measure your irrigated area in square feet — the turf only, not the whole lot.
- Find your indoor baseline from a winter bill, when irrigation is off. That is your starting point in the blocks.
- Convert: area × inches ÷ 12 = cubic feet per application.
- Stack it on your indoor baseline and read off which block the total lands in.
- Multiply the irrigation cubic feet by the rate of the block(s) they occupy — not by the first-block rate.
Step 5 is where most mental estimates go wrong, and it is why watering usually costs more than people expect.
What this page does not cover
These figures are the water commodity charge only. The daily service charge is fixed and applies whether you irrigate or not. Wastewater is billed separately and on a different basis; whether and how irrigation affects your wastewater charge should be confirmed with Utilities directly rather than assumed. Rates change — the figures above are from the current published Residential Rate Sheet and should be checked against the live schedule before relying on them for anything that matters.
Frequently asked questions
How much does it cost to water a lawn in Colorado Springs? On the Inside City tariff, with an assumed 600 cf indoor baseline and one inch of water per week, roughly $20.64 a month for 1,000 sq ft, $123.04 for 5,000 sq ft and $312.34 for 10,000 sq ft in water commodity charges.
What are the Colorado Springs water rates? Inside City residential: $0.0578 per cubic foot for the first 999 cf, $0.0721 from 1,000 to 2,499 cf, and $0.1083 at 2,500 cf or greater, plus a service charge of $0.8512 per meter per day.
How much water is one inch over 1,000 square feet? 83.33 cubic feet. The conversion is area in square feet times depth in inches divided by twelve.
Why is my summer water bill so much higher than winter? Because irrigation stacks on top of indoor use and pushes the household into higher-priced blocks. The top block costs 1.87 times the first, so the extra water is charged at the higher rate rather than the base rate.
Does halving my lawn halve my water bill? It reduces it by more than half of the irrigation portion, because the cubic feet removed are the ones billed in the highest block you reached.
Are Outside City rates different? Yes, and higher: $0.0867, $0.1082 and $0.1625 per cubic foot for the same three blocks, on a $1.2768 daily service charge.
How does a leak affect the bill? Leaked water is billed at your marginal block rate, which is the most expensive water you buy. Utilities also requires leaking sprinkler systems to be repaired within 10 days.
