Landscape Lighting

Why Install Landscape Lighting?
Landscapes are a source of pride, a refuge for relaxation, and a place to enjoy good times with family and friends. Kichler, Vista and Hinkley products bring these spaces to life after the sun goes down, providing an unmatched aesthetic effect while adding safety and usability.

benefits of Landscape lighting
BEAUTIFICATION: Focal points stand out and become more beautiful. Textures not seen in daylight become eye-catching detail. Architectural features can be accented, which brings the building and the landscape together for a resort-like feel.

USABILITY: Landscape lighting enjoyably extends the time spent outdoors. Now patios, pools, and children’s play areas become entertainment venues or just relaxing places to unwind.

SAFE PASSAGE: Hazards such as steps, low-hanging or thorny vegetation, abrupt changes in elevation or debris in a walkway can all be avoided with properly placed landscape lighting. Guests can be safely guided away from hazards.

SECURITY: It’s a proven fact that a well-lit landscape will deter potential intruders by eliminating dark areas and shadows that would conceal movement around the property.

VALUE: Landscape lighting not only brings a property to life, it also provides excellent return on investment by creating a stunning first impression when viewed by visitors.

Design Strategies
Begin by deciding the areas or objects you want to illuminate. Think about the mood or ambience you want to establish with your landscape lighting. Are you lighting the area for safe access, or using light to call attention to an architectural feature? Select the style and function of the fixtures you’ll need. There are many different low voltage landscape lighting fixtures available to create a dramatic effect and highlight your house’s architecture and features.

Path & Spread Lights
These lights are an excellent choice for lighting walkways, ground cover, and garden beds, gently washing the area with a broad blanket of subtle illumination.

Accent & Deck Lighting

This style of lighting provides the interest in your nightscape. Accent lights should be used selectively to create visual focus; too many accent lights result in competition between lighting systems.

Grazing

Lighting is placed to shine across a textured surface such as brick or stucco walls, or a natural surface such as tree bark.

Silhouetting

Reflecting light of a vertical surface behind that object can create silhouetting of an object. The light source should be concealed, usually directly behind and below the object to be silhouetted.

Up-lighting

This style of lighting provides dramatic effect. The light source is mounted or recessed in the ground and angled up to display a tree, artwork or structure

hydroseeding

Advantages of Hydroseeding
  • An affordable and versatile application
  • Protects seeds from heat and birds
  • Maintains soil temperature
  • Prevents seeds from washing away
  • Organic components enrich the soil
  • Retain moisture, which means less watering
  • Allows better root formation
  • Even application of seeds is more possible than with broadcast seeding
  • No need to remove straw as you do with broadcast seeding
  • Less than half the cost of using sod
  • Great for slopes and hard to reach areas
  • Ideal way to minimize erosion
  • Great for seeding wild flowers on lake banks and hard to reach areas
When To Use Hydroseed
  • Establish a new lawn
  • Control erosion
  • Vegetating land after fire or flood
Hydroseed Vs. Dry Seeding
  • Hydroseeded lawns come up faster. We often hear of grass up in as few as 3-5 days.
  • Hydroseed has attractive green appearance that looks far better than lawns dry seeded and covered with straw mulch.
  • Hydroseed mulch has no weed seed. Straw is loaded with weed seed.
  • Hydroseeding allows for custom tailoring of the proper seed for your job.
  • It is not uncommon to use two or three different varieties of seeds. Custom spraying the right seed for different areas of the lawn or job is sometimes necessary. When needed, we will use one seed for shady areas, one for high trafic areas, and one to make the front lawn a showpiece.
  • Hyrdoseeding mulch adds to the humus content of a lawn as it decomposes. The bacterial action of straw will leach nitrogen from the soil as it decomposes.
Hydroseed Vs. Sod
  • Hydroseeding will produce turf as nice looking as sod within a very short time at significant savings. Sod is a good solution for the need for a new lawn, but it is very expensive. Sod generally costs 3 to 5 times more than hydroseeding.
  • Sod can have a problem with the soil it was grown on not having sufficient compatibility with the soil it is planted on, which is called “not taking.” With hydroseeding, the new seedlings are grown on your own soil, so there is no risk of it not taking.
  • With sod the roots are chopped off, resulting in a less healthy plant.
  • Hydroseeding requires about 1/3 the amount of watering as sod.
  • Sod will shrink over the first month and if it is not installed properly gaps will open up between the sod rows.

Sprinkler Backflow Testing

Definition

A device that allows water to go through it in one direction, but prevents it from going backwards in the opposite direction.

A backflow preventer is like a one-way gate for water. Most backflow preventers are used to keep unsafe water from reversing flow and entering the clean water supply. Backflow preventers can be as simple as a single check valve that closes when water flow reverses. Using a simple check valve as a backflow preventer might be considered the equivalent of a turnstile at a store entrance, it is not very reliable, even a small amount of effort will overcome it. A more elaborate backflow preventer can be a complicated device that consists of multiple check valves, water release valves, air vents, and/or systems to allow it to be tested to assure it is working properly. This kind of backflow preventer might be the equivalent of an airport security checkpoint with one-way gates and an armed guard.

Basics

 You should have a backflow preventer on your irrigation system if your water comes from a “potable” (drinkable) source (see next paragraph.) If your irrigation water source is considered potable, then in most places it is illegal to not have the proper local authority-approved type of backflow preventer on your irrigation system. If your water source is non-potable, you generally are not required by law to use a backflow preventer (but not always, some jurisdiction even require them for non-potable water like recycled, reclaimed, and gray water sources).

There are many types of backflow preventers. Almost everywhere the local authorities will dictate that certain types of backflow preventers may NOT be used with irrigation systems within their jurisdiction. In some cases, the authorities will dictate the exact type of backflow preventer you MUST use. You may hear or see the term “Cross-Connection Control“, this essentially is referring to backflow prevention.  A cross connection is a connection between a drinking water supply and a source of pollution or contamination.

What’s potable water? Definition: potable water means the water is suitable for drinking. Depending on local law, that may include drinking water for animals. If you would be willing to drink it without treatment, then it is probably going to be considered potable. Non-potable water is water that is not suitable for drinking. (Once water enters into your irrigation system it is considered to be non-potable, more on that later.) Examples of water sources that are often considered non-potable are lake and pond water, water from streams, and well water from a contaminated aquifer that is not suitable for drinking. Most other wells do require a backflow preventer, even if the well doesn’t provide drinking water. This is to protect the aquifer the well takes the water from, because even if you don’t get drinking water from the well, your neighbors may get drinking water from the same underground aquifer. If you plan to apply fertilizers or pesticides using your irrigation system, then in most cases you must have a backflow preventer- regardless of the water source. Nobody wants those chemicals going into lakes, streams or the water table!

Why do you need a backflow preventer?

Your landscape has all kinds of nasty things in it that will make you sick or worse if you drink them. Thus irrigation water is officially considered a contaminant (creates a health hazard) rather than just a pollutant (is objectionable in color or odor). What’s in irrigation water? How about toxic chemicals (fertilizers, pesticides, etc.) and animal waste? (Not that I want to gross you out, but every day millions of dogs lift their legs in a fond salute to their favorite sprinkler head!) These things can and WILL come back up your irrigation pipes and into your drinking water if you don’t stop them. If you have a well, they can go down your well and into everyone else’s drinking water. If you are on a community water system they could go back up into the pipes and poison your neighbors. The valves that turn on and off your irrigation system are not sufficient to stop backflow. The purpose of the backflow preventer is to protect you when the valve breaks or leaks, which all valves will do eventually. Saving a little money by skipping the backflow preventer will not seem so smart after you spend a small fortune on hospital bills (or funeral expenses) for a poisoned family member or pet!

Now wait a minute, some people say, doesn’t the water pressure in the water system keep the irrigation water from going backwards? Yes, most of the time it does. But there are times when the water pressure drops in the supply system, and this is when the backflow occurs. No, it is not a frequent occurrence. For example when the water company has to shut off the water to repair a water pipe or hook up a new pipe. This makes construction projects easily the most common cause of backflow problems.  Fire fighting is another common cause of backflow. Fire trucks use huge pumps to suck the water out of the fire hydrants. This often causes the water pressure in the surrounding areas to drop, and backflow will occur in the surrounding neighborhoods.

You can do a quick experiment yourself and create backflow in your home pipes. Simply turn off the water valve leading to your house. Next have someone turn on a faucet. Now turn on a different faucet that is higher than the first. You will hear air being sucked into the higher faucet. You just created backflow in your house piping. Pretty easy, wasn’t it?

Another common argument against the need for backflow preventers is that if all the valves are closed the water can’t go backwards through them, so the valves should prevent backflow. The obvious problem with this is that if the backflow occurs at a time when the valve is open, like when the sprinklers are on, the valve will not stop backflow! But even when the valve is closed it may not prevent backflow. A standard manually operated valve should stop backflow when it is closed– if the valve is fully closed, has good seals, and does not leak. However most of the automatic valves, such as the electric solenoid valves used for irrigation systems, will not stop backflow even when “off” and fully closed. This is because these solenoid valves are directional in design.  If you look on the valve you will see that it has an arrow on it showing the flow direction. If the flow is reversed, the valve will often open slightly (that’s why the valve has the arrow on it- to warn you not to install it backwards!). Thus when backflow occurs and the flow direction reverses, an automatic valve will not stop the backward flow.

All sprinkler systems that are hooked to city water require a backflow preventer. This device prevents harmful things such as fertilizers to get into our drinking water. All local city utilities require the installation of backflow preventers for sprinkler systems and to be sure they are working correctly.

This device prevents harmful things such as fertilizers to get into our drinking water.

What is backflow?
Backflow is when water flows backward into the public water supply. This is usually caused when pressure in a home plumbing system is higher than the pressure distribution system. The difference in pressure can be due to a pressure drop in the distribution system. Pressure reduces when a water main bursts, pipes freeze or there is unexpectedly high demand on the water system. For example, if water is drawn from a hydrant near your home, the pressure in the distribution system could be less than in your plumbing system. The higher pressure from your personal plumbing may allow contaminated water from the ground, from storage or from other sources to be drawn into the main system.

Can I really contaminate the public water supply?
Yes. Every time you wash your car or power wash your deck, you become vulnerable to back siphonage. For example, if you leave a hose in a soapy bucket of water, or connected to pesticide sprayer, the polluted water can be pulled back through the system and contaminate the public water supply. Keep in mind that back siphonage can happen at home, business or restaurant. Outbreaks of gastrointestinal distress, hepatitis A and Legionnaires disease have been reported due to instances of unprotected backflow.

Typical backflow preventer applications
•Irrigation sprinkler systems •Air conditioning systems •Laboratory equipment •Photo developing equipment •Boilers -Swimming pools •Solar heat systems •Fire sprinkler system •Soda vending machines

Who can test my backflow preventer?
Testing of your backflow must be performed by a technician licensed and certified in the testing and repair of backflow assemblies. Most city utilities and water purveyors recommend annual inspection and testing of your backflow devices. (Depending on the size of your community you may be required to test your devices.)   Certified documentation of the testing of your backflow preventer will be kept on file at our office. Northwest Iowa Sprinkler is one of only a few irrigation and backflow testing companies in Northwest Iowa. Call today to make an appointment to have your backflow preventer installed or tested.

 

Snow Removal

Removal

Northwest Iowa Sprinkler is more than just a sprinkler system installation and repair company. During the winter months, we offer residential and commercial snow removal in Milford and Arnolds Park area. We’ll make sure your driveways, entryways, sidewalks, and parking lots are clear of snow and de-iced (if desired), creating a safe environment for employees, visitors and residents.

We also offer sanding or salting of parking lots in Milford, Arnolds Park, Okoboji and Spirit Lake. Our sand has approximately 30% salt in the mix. This keeps the sand from freezing and helps melt the ice and snow upon contact.

Salting

We also salt parking lots with Magic Ice B Gone
Magic Ice B Gone is a highly efficient solid granular de-icer. It is effective down to -35 degrees Fahrenheit. With Magic Ice B Gone you can expect to “burn off” up to two inches of snow with no plowing. Magic Ice B Gone also exhibits a residual effect, making it last longer than ordinary de-icers sometimes up to 6 or 7 days without a freeze up. Magic Ice B Gone effectiveness allows you to use 30 to 50 percent less product when compared to Rock Salt. Magic Ice B Gone is biodegradable, environmentally friendly, pet-friendly, and less corrosive than traditional treatments.

Magic Ice B Gone is safer to use on concrete and other hardscape products, is less corrosive, and will not harm curbside grassed areas or plants when used as directed.

Magic Ice B Gone starts out as ordinary rock salt and is then treated with a liquid, agricultural by-product of the distilling process blended with magnesium chloride. This patented liquid is trademarked as Magic Minus Zero. This combination process results in what we call “Magic Ice B Gone.”

Fertilizer Injector Installation

Northwest Iowa Sprinkler can install a fertilizer injector on your sprinkler system to fertilize as you water. Every time you use your irrigation system, the fertilizer injector releases small, precision doses of water soluble or liquid non-hazardous fertilizers into the water stream. One system will feed through both sprinkler and drip irrigation zones without the need to make any adjustments or nozzle changes to compensate for water flow or water pressure. This fertilizer injector will apply fertilizer in small amounts so that the fertilizer will not leach out or runoff. Call Northwest Iowa Sprinkler today to learn more about fertilizer injectors and to get an estimate. And see how much greener your lawn can be.
