MULVANE, Kan. (KSNW) -- Mulvane residents are assured that their water is safe to consume despite a more pronounced chlorine smell. The City of Mulvane normally gets its water from Augusta. However, recently, the line running from Augusta to Mulvane under the Walnut River failed, leading Mulvane to switch to its groundwater reserve system. That water is treated through Reverse Osmosis, which passes it through a filter that removes minerals, salts, and other impurities and disinfects it with chlorine. The water from Augusta is surface water, which was first treated through lime softening, then chlorine.

The chlorine typically binds with residual organic material, creating harmless chloramines, which also reduce the strength of the chlorine smell. Mulvane says until repairs are made, residents may notice a stronger chlorine smell in their water. However, it is safe, and there is no cause for concern. The city is waiting on a boring crew to put a new line underneath the river. There is no timeline on when that will take place.
