Remember that somewhat mysterious summer watering pattern that Johnson County water utility WaterOne told us about earlier this summer?

Well, it’s having an impact on water storage levels in southern Johnson County.

WaterOne put out a notice yesterday asking customers in its “South Booster” area (shown above) to follow a set of watering guidelines to ease demand on the system during peak usage periods, which have been occurring between 5 and 7 a.m. Mondays, Wednesdays and Fridays.

“Although WaterOne is producing enough water to supply this area under normal conditions, the extreme demand from 5-7 am on these days is drawing down storage levels and maxing out distribution capacity faster than our reservoirs in the “South Booster” area can recover,” read a statement put out by the utility.

WaterOne is asking residents in the South Booster area to water their lawns according to the following guidelines:

• Even numbered houses are asked to water on Mondays, Wednesdays and Fridays.
• Odd numbered houses are asked to water on Tuesdays, Thursdays and on weekends.

The utility stressed that this is not yet a restriction for these homes — just a set of guidelines they hope people will voluntarily follow — and that only the South Booster area (which does not include any part of northeast Johnson County) is affected.
