Edmond may purchase OKC water

Home kidney dialysis machines can require different operation


Special to The Sun

EDMOND — Edmond’s water supply consists of two primary sources and a secondary source. The primary sources are surface water from Arcadia Lake, and well water from the Garber-Wellington aquifer. The secondary source is treated water purchased from The City of Oklahoma City. Edmond may purchase water from Oklahoma City to supplement the city’s water supply during periods of high demand, typically during spring and summer months. Edmond city officials advised residents of the potential purchase because some home dialysis machines may need adjustment due to the different disinfection system used by Oklahoma City. The purchase has not occurred as yet and will not for at least 30 days, according to a city press release.

Although residents typically do not notice any change, kidney dialysis machines may require a different method of operation. Oklahoma City uses chloramines and Edmond uses chlorine for disinfection. Both disinfecting processes meet all state standards, and are accepted industry-wide.

Waterline connections to Oklahoma City are in the southwest section of Edmond. It is important to note that Edmond uses a process to convert Oklahoma City water to free chlorine, when that water is introduced to the Edmond water supply through the largest available connection, but before it is distributed to users. A smaller line that can be used to import Oklahoma City water is connected to a storage tank that allows the city to blend the Oklahoma City water with water produced by Edmond. This blending reduces the possibility of any user having Oklahoma City water, with chloramines, delivered exclusively to their home or business.

Although the southwest side of the city will be the most likely recipients of the Oklahoma City water, residents and businesses on the east side may receive some of the water as it blends in the distribution system with water produced by Edmond.

Water Resource Department personnel are contacting hospitals and other medical facilities to advise them of the potential purchase of Oklahoma City water. The personnel also are calling residents that are known to use home kidney dialysis.

Residents are encouraged to advise the Water Resources Department if they have a medical condition that would warrant notification prior to a change. To report a medical condition, call 216-7675 between the hours of 8 a.m. and 5 p.m.

Fish aquariums with filters may require a different method of operation due to the chloramines disinfection process. Fish owners are urged to contact their local pet store for instructions.
