Ensuring Clean, Safe, and Pure Water for Your Home or Business

In Twin Falls and throughout the Magic Valley region, residents, farmers, and businesses rely heavily on private well water systems to support daily needs—from household use to agricultural irrigation. While wells provide autonomy from municipal water supplies, they also bring distinct challenges that require specialized attention. Hard water, high iron content, sulfur odors, and microbial contamination are just a few of the common concerns facing property owners across Southern Idaho.

At Walker Water Systems Inc., we’ve spent over 25 years serving the local community with reliable, customized water treatment services designed to address the specific water quality conditions of this region. Our in-depth understanding of the local geology, aquifer conditions, and common groundwater characteristics gives us an edge in diagnosing problems and providing long-term, effective solutions.


We don’t believe in one-size-fits-all systems. Instead, we take a tailored approach—assessing each property individually and recommending the right filtration, softening, or purification technology to meet your exact needs. Whether you’re managing a household in Twin Falls, maintaining livestock in rural Idaho, or operating a commercial facility, our water treatment services help ensure a safer, more dependable water supply.


The benefits go beyond taste and clarity. Professionally treated water also enhances the efficiency of irrigation systems, reduces wear on appliances and plumbing, and protects the health of your family and animals. With cleaner, more consistent water, you’ll experience fewer repairs, lower maintenance costs, and peace of mind knowing your water system is built for the long haul.

Benefits of Professional Water Treatment Services

Improved Water Quality and Safety

One of the biggest concerns for well owners in rural Idaho is contamination. We test and treat your water for bacteria, nitrates, arsenic, and other harmful elements. Whether you're in Twin Falls, Kimberly, or Filer, we ensure your drinking water is safe and compliant with EPA standards.

Appliance and Plumbing Protection

Hard water leads to limescale buildup in pipes, water heaters, dishwashers, and laundry machines. Over time, this reduces efficiency and shortens lifespan. Our systems reduce mineral content, protecting your plumbing and improving appliance performance.

Better Taste, Smell, and Appearance

Unpleasant odors, metallic taste, or cloudy water are often caused by high sulfur or iron content. A properly installed treatment system filters out these impurities, leaving you with fresh, clean water for cooking, bathing, and drinking.

Cost Savings on Maintenance and Energy

When appliances and pipes are free from mineral deposits, they operate more efficiently. This results in lower energy costs and fewer repairs. In farming operations common throughout Twin Falls County, treated water also improves irrigation system performance and livestock health.

Customized to Your Specific Water Source

Not all water is the same—even within the same county. We perform comprehensive water analysis to determine the best treatment method for your well or water source, ensuring optimal performance and minimal waste.

Improves Agricultural and Irrigation Efficiency

In rural areas like Twin Falls and across Southern Idaho, water quality directly impacts crop yields and irrigation system performance. Professionally treated water reduces mineral buildup in irrigation lines and promotes healthier soil conditions, helping local farms maximize efficiency and protect long-term agricultural investments.

Our Water Treatment Services

Water Testing and Analysis

Before recommending a solution, we conduct thorough on-site water testing. This includes checking pH levels, hardness, bacteria, nitrates, sulfates, and metals. Understanding your water profile helps us design an effective and lasting treatment plan.

Water Softening Systems

Hard water is common in Southern Idaho. Our high-efficiency water softeners remove calcium and magnesium, reducing buildup and improving water quality. We install and maintain systems that serve residential homes, agricultural sites, and small businesses.

Iron and Manganese Removal

Staining on sinks, toilets, and laundry is often caused by excess iron and manganese. Our oxidation and filtration systems are specifically designed for high iron concentrations, a frequent issue in rural Twin Falls.

Reverse Osmosis (RO) Systems

For homes or farms looking for ultra-clean drinking water, we offer reverse osmosis systems that remove up to 99% of contaminants. These systems are ideal for kitchen use or specialized agricultural applications.

UV Water Purification

UV systems are essential for homes relying on well water, especially those in areas prone to bacteria or E. coli contamination. We install and service ultraviolet light purification units that effectively neutralize harmful microorganisms without using chemicals.

Chlorination and Chemical Feed Systems

In some cases, chemical injection systems are the most effective method to control bacterial contamination or pH imbalance. We offer precise, professionally managed systems to meet the demands of homes, dairies, and processing facilities across Twin Falls County.

Filtration Systems

From sediment filters to activated carbon units, our range of filtration systems target specific issues like chlorine, odors, and cloudiness. These are often used in tandem with softeners or UV systems for comprehensive treatment.

System Maintenance and Repairs

Just like any mechanical system, water treatment equipment requires regular servicing. We offer scheduled maintenance, filter replacements, and emergency repairs to keep your system functioning at its best—especially during high-demand seasons.

Walker is our go-to well expert in the Wood River Valley. Unlike the "other well guy" here they give you honest, straightforward advice. The two times we've been in scary "no water" situations, they were here in a flash and made things right. One of those was on Christmas Eve when a mouse decided to commit harakiri in our well's power box and shorted everything out. The "other guy" up here has one solution for all well problems: a new well for tens of thousands of dollars. Walker figures things out and fixes them. It is a pleasure to watch a stone-cold pro like Roman work.

We woke up this morning to no water in the house. We are on well water and Walker Water systems replaced our old well pump 6 months ago. We were very pleased with their previous service so I called them today. Their service person was at our home within 20 minutes and quickly found the problem, which was actually with our water softener, not our well or pump. He had the parts and fixed the problem within an hour. Phenomenal service, polite, personable, and knowledgeable -- I highly recommend Walker Water Systems for any of your water system needs!!!

Debbi B.

My pump stopped working and they came out the same day to work on it. Before they came it had started working again. They checked everything over, explained what had happened and how to prevent it and then didn't even charge me a trip charge. The business is recently under new ownership and I am glad that I will be able to save their phone number for many years in case something else goes wrong. They were professional, knowledgeable, and courteous. Thank you!
