Landscapers and farmers agree: clogging issues caused by the use of well water for irrigation can become a challenging and expensive problem. For this reason, an efficient water filtration system is crucial when using well water to irrigate crops.

What are the challenges of using well water for irrigation?

It appears as though finding and drilling for well water is the most difficult aspect of well water irrigation. However, labor-intensive installation, irrigation system design, implementation and maintenance, high energy and water consumption, and the selection of suitable water filters can be just as challenging. And, even if a new water filter prevents clogging in your irrigation system, it may be expensive to clean and maintain.  

Why you need water filtration when using well water

An irrigation system that uses sub-surface water must deal with different impurities to those found in water from surface sources. In the case of well water, the water is extracted from sub-surface water sources such as aquifers, and these sources contain more mineral substances that surface water. This high level of minerals can clog your irrigation system on two fronts. Clumped sand from well water can physically clog your system, and chemical interactions among minerals like magnesium, hard water, and fertilizers can also increase the chances of clogging.

Unfiltered well water can wreak havoc on agricultural profitability and yield, and/or compromise the appearance of the landscape. Some of the problems that can result from using unfiltered water in your irrigation system include:

  • Clogged emitters, resulting in uneven irrigation and reduced yield and/or plant damage or loss
  • Stuck or poorly functioning valves
  • Pump failure
  • Reduced pressure in the system, which can cause myriad issues including damage to the system and/or inadequate water distribution

There is more than one way to protect your irrigation system from clogging, but the best way is to prevent it. A good water filtration system will save you time and money.

What to look for in a water filtration system

When appraising different units, there are many factors to consider:

  • Filter cleaning and monitoring

Do you have the time or money to manually clean water filters? Probably not.  That’s why the first thing to look for is a reliable self-cleaning model such as the Mini Sigma. With mobile-monitored controller, either you or the machine can trigger the self-cleaning mechanism. Amiad’s app not only lets you trigger cleaning cycles, but also provides thorough reports and performance data on your filter. This lets you automate the process so you can focus on other tasks.

  • Filter durability

What is the filter housed in? Does it use screen filters? The best screen filters out there have a corrosion-free polymeric housing and internal parts. Combined with self-cleaning technology, these polymeric filters offer long-term durability. In addition, using multiple screens ensures a better filtration system. Amiad’s Mini Sigma, for example, uses both coarse and fine screens for effective filtering and they are automatically flushed.  Amiad’s app can even send you reports and performance data right to your mobile phone.

  • Water and power consumption

It’s crucial that the filter you choose is cost-effective. Durable water filtration systems with self-cleaning mechanisms like the Mini Sigma or Sigma Pro are extremely cost-effective as they decrease downtime and use less water and power. Look for water filters that use a hydraulic turbine. This is a sure sign that the filter uses less power – and saves you money.

  • Compatibility with current equipment

You shouldn’t need to buy new equipment for a premium water filter! A flexible inlet-outlet configuration makes it easy to adapt new technology to your current equipment.

  • User-friendly installation and low maintenance

Don’t spend hours trying to figure out a complicated installation manual. That’s not worth your time or your money. Instead, look for companies that create user-friendly well water filters with quick installations.

  • Can it handle low pressure?

The last thing you want is vacuum formation and other disruptions in your well water filtering system. The ideal system is not only effective at 1.5 bar (22 psi) during the flush cycle, but also alerts you to high and low pressure.

If you ask these six questions, you’ll find a water filter for your irrigation system that not only knows how to handle the clogging factors found in well water, but is also low maintenance, cost-effective, and user-friendly.

The search for a filter for your well water irrigation is over

Amiad offers two new water filters – the Sigma Pro and Mini Sigma – that have self-cleaning mechanisms, mobile-monitoring, and corrosion-proof polymeric housing. Like all the Sigma series filters, these models are water and power efficient and effective even during low pressure operation. In addition, the units are easy to install and allow for multiple configurations – making them compatible with your equipment. It’s important to note that both filter models are ideal for filtering water for irrigation from various sources – not just well water.

With Amiad’s water filtration systems, you are guaranteed the highest, most cost-effective results for water irrigation. To learn more about the Mini Sigma, Sigma Pro, or any of our other innovative irrigation water filtration solutions, contact us here.
