Sprinkler Design Services

Design Strategies

We start the process with a precise measurement of your lawn. We then visit with you to learn about your flower beds, trouble spots and future landscaping plans. Once we are finished, we will put together a proposal that will include a design. The design will show the number of heads, approximate location of these heads, water service location and controller location. Your proposal will be custom designed for your property. You will also receive literature that will help you understand the operation of your system. Once the sprinkler system is installed we will show you how to operate your system. 

Every new system we install will receive an “As-Built” included at no additional charge. The As-Built is a design drawing with all of the pipes, valve boxes and heads in a map of the system as it was built.

Some systems over water in some areas and under water in others. All sprinkler systems designed by us, employ the “balanced precipitation” concept using head-to-head coverage. In order to achieve consistent water coverage, each head must spray far enough to reach the next head. We install all of our sprinkler systems with this concept so that all parts of your lawn will be watered evenly.

Things to Remember

A Lawn Irrigation system will help maintain the value of your property. With proper lawn care and efficient watering of your lawn and plantings a sprinkler system will help beautify your home.

All irrigation systems must be installed properly and maintained regularly. An irrigation system is exposed to many elements: snowplows, car tires, lawn mowers, cold weather, etc. With family time becoming more valuable and you find that you do not have the time or knowledge to check your system, start up the system or program the system for different times of the year. Call Northwest Iowa Sprinkler or send us a Service Request and we will promptly call you back and service your needs. 

You can now operate your sprinkler system with your homes wifi and the free Rainbird app anytime of day and from anywhere you are with your smart phone or tablet. If you do not have interest in changing the settings on your controller at the controller or with the wifi app we can do it for you remotely with your homes wifi connection.

Try to water in the early morning, between 4 a.m. & 9 a.m. The greatest waste of water comes from applying too much, too often – much of the water is never absorbed.  We recommend watering early moring for three reasons. 

  • Watering in the early morning has a lesser chance of evaporation vs watering during the heat of the day.
  • It is typically the least windy in the early morning than any other time of day. That will allow the water droplets from the sprinkler head to reach their destination.
  • The early morning is the best time to water to avoid fungus and disease and also avoid evoporation.  When you water in the early morning and the sun comes up this will dry the grass blade.  Then the chance for disease and fungus diminishes.  If you water in the evening the grass blades will likely stay wet all night and that can cause fungus and disease to grow.

Water your lawn deep, longer not often is the rule: It is recommended that your lawn receive 1” of water weekly.  It is always best to water longer less often because this will promote a deeper root system.  If you water often and for short periods the water does not soak deep into the soil and will promote a shallow root system.  By watering deep less often you will get healthier turf and you will use less water.  

If you have heavy clay soil you will have to water a little more creatively.  Instead of watering for one long session try watering a few times for shorter periods the same day and take a break in between each session. This will allow water to soak in, while minimizing runoff. This will help establish stronger roots and a healthier lawn.  As the sun becomes stronger in July and August the evaporation level is stronger and you should adjust your controller to run zones longer to ensure your lawn is getting enough water during these months.

Install a rain sensor. In some states a rain sensor is now required. A rain sensor is a smart way to help conserve water. 

Installing a soil moisture sensor is also a good idea.  The soil moisture sensor is installed in the soil in one of the drier spots in the yard.  This device once installed will regulate the sprinkler system based on the soil moisture.  The adjustable threshold can be adjusted to meet all types of soil and will turn on and off the sprinkler system once the threshhold is met. 

For your investment, our team will create a custom design that meets your expectations and the watering needs of your landscape. After installation, you will receive a laminated as built (Drawing of the entire system showing how it was installed, and where the sprinkler heads, controller, distribution valves and pipe are and all in a color format), free service agreement for the first 12 months and a warranty for 24 months. Our team of experts will answer questions and give you confidence in your new system at no extra charge. Now, THAT'S VALUE!
