Nebraska has roughly 250,000 private domestic water wells serving approximately 15% of the state's population, a figure that's highest in rural counties like Washington, Dodge, Saunders, and Cass, where many of our customers in Blair, Fremont, Ashland, and Elmwood live. City water and well water aren't just different in source. They call for fundamentally different approaches to treatment, because the problems they present are different in kind, not just degree.
Understanding those differences is important for any homeowner making a water treatment decision. The right system for a Gretna homeowner on city water is often very different from the right system for an Ashland acreage on a private well, even if both homes are experiencing hard water. This guide walks through the key distinctions and what each situation typically requires.
City water: what you're starting with
Municipal water in the Omaha metro is treated before it reaches your home. Metropolitan Utilities District draws from the Missouri River and Platte River system, runs it through sedimentation, filtration, and disinfection, and delivers it meeting all EPA Safe Drinking Water Act standards. The City of Fremont, the City of Blair, and other municipal utilities in our service area do the same for their residents.
That treatment process handles bacterial safety and removes significant contamination from the source water. What it leaves behind, intentionally or as a byproduct, includes mineral hardness (14 to 20-plus grains per gallon across most of the metro), chlorine and chloramines used for disinfection, and disinfection byproducts formed when chlorine reacts with organic matter in source water. In homes with older plumbing, lead from service lines or household fittings can enter the water after it leaves the utility's distribution system.
For city water households, the whole-home water softener is the most common and impactful system, addressing mineral hardness throughout the home. A carbon filtration system addresses the chlorine taste and smell. Many families pair both in the softener-filtration combo. For drinking water quality, an under-sink RO system handles lead and other dissolved contaminants more precisely than whole-home filtration can.
Well water: a different problem set
Private well water isn't treated before it reaches your home. What's in the aquifer is what comes out of your tap. That makes well water fundamentally different from a treatment standpoint. The specific water quality of any given well depends on aquifer depth, local geology, and the land use history above the aquifer. Two neighboring properties can have meaningfully different well water quality.
In eastern Nebraska, the most common well water problems we encounter are high iron and manganese (from the iron-rich alluvial soils along the Platte and Missouri River valleys), mineral hardness (often higher than city water in the same area), low or high pH (influencing corrosivity toward plumbing), hydrogen sulfide (producing a rotten-egg smell), high nitrate concentrations (in areas with heavy agricultural fertilizer use, per USGS data on the Platte Valley aquifer), and microbial contamination (bacteria, occasionally protozoa).
For well water households, bacterial safety is the starting concern, not because bacteria is present in every well, but because the consequences of it being present and undetected are serious. The UV purification system provides continuous disinfection for every gallon entering the home, using UV light without adding any chemicals. Unlike shock chlorination, which is periodic, UV protection is ongoing. Iron filtration, a softener, and sometimes a pH neutralizer address the mineral and chemical issues that affect fixture life and water usability. For drinking water nitrate concerns, especially significant for households with infants, an RO system at the kitchen sink is the most direct solution.
Why testing first is non-negotiable for well water
For city water, you know the source, and the utility's annual Consumer Confidence Report gives you general parameters. The treatment decision is simpler: address hardness, address taste and smell, protect drinking water quality. For well water, you don't know what's in your water until you test it. Recommending a treatment system for a private well without a comprehensive water test is irresponsible. It's guessing.
- Iron and manganese: determined by concentration, since low iron needs a different approach than high iron.
- pH: determines whether a neutralizer is needed and what type of filtration media will work.
- Bacteria: present or not, and if present, the type matters for treatment design.
- Nitrates: concentration determines whether an RO system is warranted.
- Hardness: well water hardness often differs significantly from city water hardness in the same area.
- TDS: total dissolved solids gives a baseline picture of overall water chemistry.
Our comprehensive well water test covers all of these parameters. It takes about an hour at your home and the results tell us everything we need to design the right treatment system, not a default package, but equipment matched to your specific well's chemistry.
Which is more expensive to treat: city or well water?
Generally, comprehensive well water treatment requires more equipment than city water treatment, because there are more parameters to address. A city water household typically needs one to three systems (softener, carbon filter, and maybe RO). A well water household may need sediment pre-filtration, iron filtration, a softener, UV disinfection, and an RO system for drinking water.
That said, the right answer isn't always the most comprehensive system. Some rural wells in our service area test clean for bacteria and have manageable iron and hardness levels, so those households may only need a softener and iron filter. Others test for multiple problems simultaneously and need a more complete treatment train. The test tells us what's actually needed.
