Throughout the month of April, the Bossier City Water System will be converted back to pre-October 2018 operation. The conversion from free chlorine back to using chloramine as the primary disinfectant will begin Wednesday, April 3, 2019. The transition will involve a heavy, system wide water flush that will take place over the next few weeks. As the flush progresses, consumers will experience a noticeable reduction in chlorine taste and odor in their water.


The temporary switch to free chlorine from chloramine began in October 2018. Disinfectants (chlorine or chloramines) are used by water suppliers to kill bacteria and other microorganisms in drinking water. Water systems that use chloramines temporarily change to chlorine in order to clean water pipes and provide a reliable disinfectant residual throughout all points in the water system. Free chlorine is proven to be more effective in killing microorganisms within the pipes of the distribution system.


Following the state ordered chlorine cleanse, the Bossier City Water System began reducing chlorine levels in early January 2019. The system will be converted back to pre-October 2018 operation beginning Wednesday, April 3, 2019. The Bossier City Water System will continue to closely monitor disinfectant residuals.


Infrastructure and operational changes are being implemented to ensure that disinfectant residuals remain at productive levels. These include the following:

  1. Installation of 22 automatic flushing units on fire hydrants to automatically flush older water from the distribution system.
  2. Construction of two chemical boosting stations at the Hwy. 71 South Water Tower and the Northeast Water Tower.
  3. The implementation of enhanced sampling and flushing procedures.
