Spot the Problem
Signs Your Water Needs More Than a Filter
Well water problems usually announce themselves through your senses or your fixtures. These are the signs that bring most homeowners to us.
- A rotten egg odor, often strongest from the hot water
- Orange, red or brown stains in sinks, toilets and laundry
- Black specks or slimy buildup in toilet tanks
- Water that turns cloudy or tinted after it sits
- A metallic taste in drinking water or coffee
- A lab report showing bacteria in your well
Well Water Treatment Starts With a Water Test
A private well is the owner's responsibility, and no utility is treating it before it reaches your tap. Well water treatment works best when it is based on a recent test that shows iron, manganese, hydrogen sulfide, pH, hardness and bacteria levels. We review your results with you or help you get a sample tested.
Many wells have more than one issue at once. Iron and sulfur often show up together, and low pH water can make both harder to remove. We design the system in the right order, so each stage protects the equipment that comes after it.

Iron Filter for Well Water and Staining Problems
Iron is one of the most common complaints from well owners. Dissolved iron looks clear coming out of the tap, then turns orange or brown once it meets air, staining fixtures, laundry and dishes. An iron filter for well water converts the dissolved iron into solid particles and traps them in a filter bed.
Most iron filters clean themselves on a schedule by backwashing the trapped material down the drain. Some systems use air injection to help the process, while others use a media bed that needs occasional regeneration. We size the filter to your iron level and your household flow, so the water stays clear from the first tap to the last.

Getting Rid of a Sulfur Smell in Water
A sulfur smell in water usually comes from hydrogen sulfide gas, which gives water that rotten egg odor. It can come from the well itself or from bacteria living in the plumbing. When the smell appears only on the hot side, the water heater's anode rod can be part of the cause.
The fix depends on where the odor starts and how strong it is. Treatment can include aeration, oxidizing filters or a chlorine or peroxide feed paired with a carbon filter. We confirm the source first, so you are not paying for equipment that misses the real cause.
UV Water Disinfection System for Bacteria Protection
A UV water disinfection system uses ultraviolet light to disable bacteria, viruses and other microorganisms as water passes through a chamber. It adds no chemicals and does not change the taste of the water, which makes it a popular final step for private wells.
UV only works on clear water, so it is installed after the filters that remove sediment, iron and hardness. The lamp needs replacing on a regular schedule and the quartz sleeve needs cleaning. We set the system up so these tasks are simple and show you what each part needs.

Our Water Testing and Treatment Process
Each project follows the same path, from understanding the water to confirming the results after installation. Testing comes first, because every later choice depends on it.
-
Test and Review
We review a current water test or help you collect a sample, then explain what each result means for your home.
-
Design the System
We choose the stages, the sizes and the order of equipment, and confirm where the system will be installed and drained.
-
Install and Start Up
We install the equipment, add bypass valves for service, handle any required permit or inspection, and program each unit.
-
Confirm the Results
We check water quality after startup and show you how to maintain each part, from filter media to UV lamps.
What Affects the Price of a Water Treatment System in Wilmington, DE
The cost of a treatment system depends on what is in your water and how much of it needs treating. A single stage for mild iron costs less than a multi stage setup that handles iron, sulfur, pH and bacteria together. The flow rate your household needs also sets the size of each unit.
Installation details matter as well, including floor space, a drain for backwashing and power for UV or control valves. We give you a clear quote for your water treatment system in Wilmington, DE once we know the test results, with each stage explained.

Water Treatment Questions
Water Treatment System FAQs
How often should I test my well water?
A yearly test for bacteria is a good habit for any private well, and a broader test every few years helps track iron, sulfur, hardness and other minerals. Test again after flooding, after work on the well, or any time the water changes in color, taste or smell. Results guide every treatment choice we make.
Can one system remove both iron and sulfur?
Sometimes. Several filter types handle moderate iron and hydrogen sulfide in a single tank, especially those that use air or an oxidizer to help the process. Higher levels often need separate stages. We look at the actual numbers from your water test before recommending a single unit or a combination, so neither problem slips through.
Does a UV system need a lot of maintenance?
Not much, but it does need regular attention. The UV lamp is typically replaced once a year because its output fades even while it still glows. The quartz sleeve around the lamp should be cleaned so the light can reach the water. Prefilters upstream also need changing so the water stays clear enough to treat.
Why does only my hot water smell like rotten eggs?
When the odor appears only on the hot side, the water heater is often involved. Bacteria in the tank can react with the magnesium anode rod and produce hydrogen sulfide gas. Swapping to a different anode or treating the well water can solve it. We check both the heater and the supply to find the true source.
