Cedar Park City Council voted Aug. 13 to ease certain water usage rules. Utility Program Manager Nanette McCartan said the changes allow charities to hold car wash fundraisers. The changes also permit residents to wash their cars any day of the week and to run outdoor fountains. But charities or residents washing cars would need to use hose nozzles and automatic shutoff devices to prevent wasted water, McCartan said. Before council approved the changes city residents were under other watering restrictions that banned charity car washes and restricted outdoor fountains that do not support fish or recycle the water. Other Stage 3 watering restrictions, such as a limit of once-a-week watering, remain in place for city residents.
