The project to convert Tulsa's water treatment system to a chloramine-based process is about halfway finished, and water customers will see a notice in their May bills, KRMG has learned.

Joan Arthur, a city engineer who's in charge of the project, says the contractor began work in February and is due to complete the equipment installation by mid-June.

The city would then complete the conversion by the end of June, she told KRMG.

Arthur says people who have aquariums or ponds can begin using the filtering systems that remove chlorine, and especially ammonia, from the water without ill effects.

Those chemicals and/or filters are available now at local retailers.

She added that all area dialysis providers have been notified of the upcoming change.

Those interested in additional information about the conversion and chloramines can visit the city's website dedicated to water issues.
