Safe and Reliable

We want to assure you that Longmont’s drinking water remains safe for you to use and that you’ll continue to have an uninterrupted supply of drinking water, during the COVID-19 outbreak and every day.

Here are a few other things you should know:

  • We have a drinking water supply that comes from clean and natural sources in the Rockies – it’s easy to treat to create safe drinking water.
  • We are constantly treating your drinking water through advanced treatment processes and testing it to make sure it’s safe.
  • COVID-19 is not a waterborne disease, it’s a respiratory disease that’s spread more like a common cold, but even so, our treatment processes remove viruses.
  • We have excellent plans and well-trained staff that make us resilient to unexpected events like floods, epic snow storms, power outages, and now, COVID-19. You can expect a continuous and uninterrupted supply of drinking water.
