Chlorine Conversion FAQ

Frequently Asked Questions

  • Will my water smell or taste like chlorine?

Beginning August 3, 2026, the City will temporarily change its water treatment method from chloramines (chlorine combined with ammonia) to free chlorine. This can cause a stronger chlorine smell or taste that should dissipate in 2-4 days. The water is still safe to drink and use.

  • Is the water safe to drink and use?

Yes. The water meets all state and federal health standards and is safe for drinking, cooking, bathing, and everyday use. If you have any specific health concerns, please consult with your doctor. 

  • What is a “free chlorine rinse” and why is the City doing it?

This is a temporary switch in disinfectants to help clean and maintain the water system. It helps remove buildup and improves water quality. It’s a routine, industry-recommended maintenance practice.

  • Why is chlorine used in our drinking water in the first place?

Chlorine has been used in public water systems for over 100 years to keep drinking water safe by preventing the growth of harmful bacteria.

  • What can I do if I don’t like the chlorine smell or taste?

You can chill your tap water in an open container in the fridge for a few hours. Adding lemon juice, or using a water filter from a reputable manufacturer bearing the NSF/ANSI 42 certification.

  • I have a family member on dialysis. Is this safe?

Dialysis machines must be adjusted for disinfectant changes. Local dialysis centers have been notified about the switch and should be monitoring for this temporary change.

  • Is the water safe for pets?

Yes, for most pets like cats and dogs. However, fish tanks and ponds still need a water conditioner to neutralize chlorine. 

  • My water looks cloudy or dirty. Is that normal?

Yes, it can happen when we flush the system to distribute the chlorine. Run cold water from a backyard faucet or bathtub for several minutes. If it doesn’t clear within an hour, please contact us on our online Report It system.

  • Why are fire hydrants being flushed all over town?

Flushing helps the free chlorine reach all parts of the water system and clears out stagnant water. We’ll also flush again when switching back to chloramines.

  • My water pressure dropped—what’s going on?

Hydrant flushing can temporarily lower pressure in nearby areas. It usually returns to normal quickly. If it lasts more than an hour, let us know.

  • Can I do laundry if my water looks discolored?

If you’re experiencing this, it’s most likely our first few days of conversion, and it’s best to wait. If your water looks cloudy or discolored, it might stain clothes. Run a faucet until the water clears before doing laundry.

  • Do I need to treat my pool water differently?

No changes are needed. Just keep maintaining your chlorine levels as usual.

  • I have a fish tank or pond. What should I do?

You should be able to continue using your regular water conditioner. Most commercial products safely remove both chloramines and free chlorine.

  • How long will this last?

This process will last just under 30 days. The City will switch back to chloramines around August 31.
