Temporary Change in Water Treatment Process Planned

Coatesville District:

Pennsylvania American Water will be temporarily changing its disinfection treatment process in its Coatesville area water system. This change from chloramine disinfection to free chlorine might cause some customers to notice an increase in the taste and smell of chlorine in the water. The treatment change is necessary as part of our distribution (pipeline) maintenance program, and it will take place starting Wednesday, August 10, for approximately six to eight weeks.

In addition, crews will be flushing parts of the distribution system during this period. If crews are flushing in your area, you might notice discolored water. This is normal and will only be temporary while we complete this system maintenance. Thank you for your cooperation.
