Irrigation, Sprinklers and Blowouts in Bismarck, ND
Bismarck Landscape installs, repairs, starts up and blows out lawn sprinkler systems in Bismarck, ND, plus Mandan and Lincoln. Every system we touch is set up for three local facts: heavy clay that soaks up water slowly, summer water bills on a tiered rate, and winters cold enough to crack any pipe with water left in it.
Most Bismarck systems should be blown out before the first hard freeze, and the first frost usually comes around September 20 to 25. Contact Bismarck Landscape to get on the blowout list.
What’s Included
Our Irrigation and Sprinkler Services in Bismarck
-
01
Sprinkler System Installation
New in-ground sprinkler systems for lawns and beds, designed zone by zone around sun, shade, slopes and soil. On new builds, we install before sod goes down, so trenches don’t scar a finished lawn. Every system gets a spot for a smart controller and easy access to the blowout point.
-
02
Sprinkler Repair
Broken heads, leaking valves, dry spots, zones that won’t turn on, and controllers that don’t keep time. Many spring repairs in Bismarck come from winter: heads clipped by snow blowers and plows, or pipes and fittings cracked by water left in them.
-
03
Spring Startup
We turn the water back on slowly, check every zone, fix or adjust heads, look for leaks and set the controller for spring weather. This is also when hidden winter damage shows up.
-
04
Fall Sprinkler Blowouts
We use compressed air to push water out of the pipes, heads, valves and backflow preventer before the ground freezes. Valves and backflow preventers are the parts most likely to crack if water freezes inside them.
-
05
Smart Controller Upgrades
Weather-based and soil moisture controllers that skip watering when it rains and adjust through the season. They’re one of the easiest ways to cut a Bismarck summer water bill.
LOCAL WATER COSTS
Why Summer Watering Costs More in Bismarck
Bismarck charges residential water on a tiered rate, so each extra unit of water costs more once you pass a certain amount. The City of Bismarck explains why:
- The city uses about 200 million gallons of water a month in its off season.
- From May through September, demand climbs to 600 million gallons or more.
- The city says that peak is “largely driven by our residential irrigation users.”
- Pipes, pumps and treatment have to be sized for that summer peak, about three times normal use, even though most costs stay the same all year.
In plain terms, lawn watering is what pushes the city’s system to its limit, so heavy summer watering is priced higher. The good news: a well-set system uses much less water than one running on a spring schedule all summer. See our guide on how to lower your summer water bill.
How Much Water Does Your Lawn Really Use?
Bismarck bills water in units. One unit is 100 cubic feet, or about 748.5 gallons.
Here’s the math most people never see. One inch of water on 1,000 square feet of lawn is about 623 gallons.
| Lawn size | Gallons for 1 inch of water | About how many billing units |
|---|---|---|
| 2,500 sq ft | About 1,560 gallons | About 2 units |
| 5,000 sq ft | About 3,120 gallons | About 4 units |
| 8,000 sq ft | About 4,990 gallons | About 7 units |
At about 1 inch a week, a 5,000-square-foot lawn needs around 4 units of water a week, or roughly 16 to 18 units a month, on top of what your house uses. That’s why July bills jump. Our lawn care in Bismarck page explains when you can let a lawn go dormant to save water.
WATERING ON CLAY
How to Water a Bismarck Lawn With a Sprinkler System
- 01Aim for about 1 inch a week, counting rain. That’s the amount NDSU Extension recommends for most lawns.
- 02Water deeply, once or twice a week. Short daily runs keep roots near the surface.
- 03Split each run on clay. Heavy clay soaks water in slowly, so water can run off before it sinks in. Two shorter runs an hour apart let it soak down. For standing water beyond the sprinkler schedule, see yard drainage and grading.
- 04Water when it’s cool and calm, like early morning. The City of Bismarck also suggests skipping windy days and waiting when rain is in the forecast.
- 05Check your coverage. Set a few empty tuna cans around a zone, run it for 15 minutes and measure. It tells you how long each zone needs to put down an inch.
- 06Change the schedule with the season. A lawn needs less water in May and late September than in July.
- 07Water shade and sun differently. Shady zones under big trees need less.
SPRINKLER TROUBLESHOOTING
Common Sprinkler Problems in Bismarck
| What you notice | Likely cause | The fix |
|---|---|---|
| Broken or crooked heads along the driveway in spring | Snow blowers, plows or piles hit them over winter | Replace heads; mark them with stakes before next winter |
| A zone won’t turn on | Bad valve, wiring or controller | Test the valve and wiring, then repair |
| Water bubbling up in the lawn | Cracked pipe or fitting, often from freezing | Dig, find and repair the break |
| Brown strips or dry spots | Heads tilted, blocked or spaced wrong | Adjust, clean or add heads |
| Water running down the sidewalk | Clay soil can’t soak it in fast enough | Split runs into shorter cycles |
| Backflow preventer leaking in spring | Water froze inside it | Repair or replace, and blow out on time next fall |
| High bill in July | Controller still on a heavy schedule, or a hidden leak | Reset the schedule, check for leaks, consider a smart controller |
Driveway stakes help on both ends of the year. Our snow removal page explains how marking edges and heads before winter keeps blowers and plows off them.
FALL WINTERIZATION
When Should You Blow Out Sprinklers in Bismarck?
Blow out your sprinklers before the first hard freeze. In Bismarck, that usually means late September through mid-October, since the first frost typically lands around September 20 to 25.
A light frost usually isn’t the problem. A hard freeze that lasts, with nights well below freezing, is what cracks the parts sitting above ground, like the backflow preventer. Don’t wait for the last warm week in October to call, since that’s when every blowout schedule in town is full.
For timing tips and what happens during a blowout, read when to blow out your sprinklers in Bismarck.
SPRING STARTUP
When Should You Turn Sprinklers On in Spring?
Wait until the risk of a hard freeze has passed, which in Bismarck is usually around mid-May. The last spring frost averages around May 12 to 14. Turning the system on in April and then getting a cold snap can crack the backflow preventer all over again.
Spring rain often keeps lawns green through May anyway. When you do start up, open the main valve slowly so a rush of water doesn’t slam the pipes, then run each zone and look for broken heads and leaks.
SAVE WATER, NOT COMFORT
Are Smart Sprinkler Controllers Worth It?
For most Bismarck homes, yes. The U.S. EPA’s WaterSense program says as much as 50% of outdoor watering is wasted through overwatering. It also says replacing a standard clock timer with a WaterSense labeled controller can save a home up to 15,000 gallons a year.
There are two main types:
- 01Weather-based controllers use local weather to adjust the schedule, and skip watering when it rains.
- 02Soil moisture controllers use a sensor in the ground and only water when the soil is dry.
With Bismarck’s tiered rates, the water a smart controller saves comes off the most expensive part of your summer bill. Both types still need to be set up and adjusted right to work well.
SPRINKLER SYSTEM PRICING
How Much Does a Sprinkler System Cost in Bismarck?
A new sprinkler system in Bismarck usually costs about $600 to $800 per zone. Published local cost guides put the average install around $2,300. Most homes need several zones:
| Number of zones | Typical installed price |
|---|---|
| 2 zones | About $1,100 to $1,500 |
| 3 zones | About $1,700 to $2,300 |
| 4 zones | About $2,300 to $3,100 |
| 5 zones | About $2,900 to $3,800 |
| 6 zones | About $3,400 to $4,600 |
| 8 zones | About $4,600 to $6,100 |
These are market estimates, not quotes. Blowouts, startups and repairs are priced per visit after we see the system.
What Changes the Price of a Sprinkler System?
- Number of zones, based on lawn size and how many areas need different watering
- Sod or bare dirt, since installing under an existing lawn takes more care
- Beds and trees that need drip lines instead of spray heads
- Controller type, such as a basic timer or a smart controller
- Slopes and tight spaces
- Distance from the water line and the backflow setup

Have a question that isn’t here?
Find more helpful answers in our irrigation and sprinkler resources.
When should I blow out my sprinklers in Bismarck?
Before the first hard freeze, which usually means late September through mid-October. Bismarck’s first frost typically comes around September 20 to 25, and a hard freeze can crack backflow preventers, valves and pipes.
When can I turn my sprinklers on in spring?
Usually around mid-May, after the risk of a hard freeze has passed. Bismarck’s last spring frost averages around May 12 to 14. Turning water on too early can crack the backflow preventer in a cold snap.
How long should I run my sprinklers?
Long enough to put down about 1 inch of water a week, counting rain. Set a few empty tuna cans in each zone, run it for 15 minutes and measure. On clay soil, split each run into two shorter cycles so the water soaks in instead of running off.
Why is my summer water bill so high in Bismarck?
Bismarck uses tiered water rates, so the more you use, the more each unit costs. City demand climbs from about 200 million gallons a month to 600 million or more from May through September, mostly from lawn watering. A 5,000-square-foot lawn needs about 3,100 gallons for each inch of water.
How much does a sprinkler system cost in Bismarck?
Usually about $600 to $800 per zone. Published local cost guides put the average install around $2,300, and a 4-zone system typically runs about $2,300 to $3,100.
Is a smart sprinkler controller worth it?
For most homes, yes. The EPA says a WaterSense labeled controller can save a home up to 15,000 gallons a year. With Bismarck’s tiered rates, those savings come off the most expensive part of your summer bill.
