North Texas Municipal Water District (NTMWD) Temporary Change in Disinfection

Annual System Maintenance: March 4 – April 1, 2024

Water disinfection is required to protect public health and keep our water safe. North Texas Municipal Water District (NTMWD) uses proven and highly effective disinfection methods to treat the water we deliver to over 2 million North Texans. Our annual temporary change in disinfection is required to protect public health. This maintenance procedure is essential to keeping our water safe as it travels to your tap across our 2,200-square-mile service area.

NEED FOR DISINFECTION

Disinfection is a critical part of water treatment to keep water safe. During NTMWD’s normal water treatment processes, disinfection is a two-step process that first treats the water at the plant and second adds disinfectant to maintain water quality as it travels long distances through pipes to homes and businesses. Both steps are needed to keep tap water free of harmful microorganisms, such as parasites and viruses.

NTMWD uses a combination of ozone and free chlorine (first step) to disinfect water at the treatment plant and then adds ammonia to form chloramines (second step) before leaving the plant. This maintains required water disinfection levels from the time it leaves the treatment plant all the way to your tap. According to the Texas Commission on Environmental Quality (TCEQ): “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.”
