Drinking Water Disinfection and the Free Chlorine Conversion Process FAQs PDF Print E-mail

Why is drinking water disinfected?

Disinfecting drinking water is critical to protecting consumers from disease-causing microorganisms, called pathogens, including bacteria or viruses. Disinfectants are very effective at inactivating (or killing) pathogens and have enormously benefited public health. For example, the incidence of typhoid fever was reduced by 1000-fold in the US in the last century by implementing the disinfection of drinking water.

Even with the advancements in drinking water disinfection practices and decreased incidence of diseases like typhoid fever and cholera in the US, disinfection of public drinking water remains critical for public health. Recent failures to adequately disinfect water have led to high-profile illness outbreaks and deaths (for example, the 1991 Peru cholera epidemic and the 2000 Walkerton, Canada bacterial outbreak).

What are the drinking water disinfection requirements in Texas?

Public water systems are required to disinfect water prior to its entering the distribution system that carries it through pipes for delivery to consumers. Public water systems in Texas are also required to maintain a minimum amount of residual disinfectant throughout the distribution system to make sure that harmful microorganisms stay low. Treatment prior to distribution may utilize a number of different disinfectants, but a public water system is required to use either chlorine or chloramine in the distribution system.

What is chloramine?

Chloramine is a long-lasting disinfectant added to public drinking water for disinfection. It is formed by combining chlorinated water with small amounts of ammonia. It is commonly used for disinfection in many public water systems throughout Texas, the United States, and countries around the world.

The City of Trinidad public water system, (PWS) ID 1070004 will temporarily convert the disinfectant used in the distribution system from chloramine to free chlorine. The conversion will begin on AUGUST 10, 2020 and continue through SEPTEMBER 10, 2020 During this period, you may experience taste and odor changes associated with this type of temporary disinfectant conversion.

Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Chloramine, free chlorine combined with ammonia, is widely used as a disinfectant because it persists for long periods while also limiting the formation of disinfection by-product contaminants. Prolonged use of chloramine coupled with other factors that can impact water quality, such as high temperatures or stagnation of water, may result in the growth and/or persistence of organic matter within the pipes of the distribution system, which may hinder the ability to maintain an adequate disinfectant residual. A temporary conversion to free chlorine, partnered with flushing activities, helps to rid distribution pipes of this organic matter and improve the quality of your water overall.

The City of Trinidad has chosen to implement a temporary disinfectant conversion to free chlorine based on the following:

It is being used as preventive maintenance to kill bacteria that, though harmless when consumed by humans, can introduce unwanted taste and odor, and create issues with maintaining a disinfectant residual.
