Protect Your Home’s Water with UV Light Bacteria Disinfection
If you rely on well water at home, you may have heard of using chlorine to disinfect or “shock” the well. This is often the suggestion after a water test showing E. coli or coliform bacteria in the water. This process involves adding a high concentration of chlorine bleach to disinfect the entire well system.
Chlorine is a powerful chemical that kills bacteria. But, it also introduces harsh compounds into your water system. The strong odor and taste can linger, and overuse may corrode plumbing and fixtures over time.
More importantly, while well shocking may be helpful in the short term, it’s not a permanent solution. Shocking only addresses contamination after it happens—it doesn’t stop bacteria from returning.
For a long-term, chemical-free approach, many Indiana homeowners are turning to UV. These systems provide continuous protection against bacteria, without the drawbacks of repeated chlorine use.
How UV Light Works Against Bacteria in Water
UV systems expose water to short-wavelength light (called UV‑C). This light damages the DNA of germs—like bacteria, viruses, and protozoa—so they can’t reproduce. That means as soon as the water flows through the unit, it neutralizes up to 99.99% of harmful microorganisms. What’s more, UV-C light will address even chlorine-resistant pathogens, such as E.coli, Giardia, and Cryptosporidium without the use of chemicals or byproducts.
UV vs. Chemicals: Why Choose UV for Well Water
UV vs. Chemicals: Why Choose UV for Well Water- No Wasteful Chemicals or Taste Issues: Unlike chlorine or ozone, UV adds nothing to your water and preserves the natural flavor.
- Fast, Reliable, and Low-Maintenance: UV systems work instantly and require minimal upkeep.
- Safe & EPA‑Approved: UV disinfection is EPA-approved and used in municipal, commercial, and residential settings.
Do You Need a UV System?
You should consider a UV system for your home if:
- You rely on well water for drinking or cooking
- You want accurate, chemical-free pathogen control
- Your recent lab test is positive for bacteria. If you have not had your well tested, C&J can do that for you.
A UV system doesn’t remove sediment, chemicals, or minerals from your water. It works best when bundled with other treatment systems like a water softener and reverse osmosis system.
How to Choose the Right UV System
There are different UV systems for smaller to larger water volume needs. The average gallons per minute (GPM) needed for households varies based on family size and typical water usage. Here’s a rough breakdown for family size:
- 1–2 people: 5–7 GPM
- 3–4 people: 8–12 GPM
- 5–6 people: 12–15 GPM
- 7+ people: 15+ GPM
The GPM should factor in uses like running a shower, washing machine, and faucets all at the same time. Households with multiple bathrooms or large appliances may need a higher GPM.
Choosing a system sized for your water flow rate or your average gallons per minute (GPM) could be confusing. If you are unsure what your GPM is, contact C and J Water. We are happy to help you determine the best solution for your family.
