Wichita officials had a ribbon-cutting ceremony Friday for the city’s new water treatment plant. Mayor Lily Wu said the plant won’t be commissioned until next year, but it has reached functional completion. She said it will serve about 20 percent of Kansas residents with clean and safe drinking water. Public Works Director Gary Janzen gave credit to previous director Alan King for his guidance and direction in starting the project. Janzen said the next steps will be to conduct performance testing, which has already begun. He said the facility will be pumping an average of 50 million gallons per day to its customers, with a capacity to supply 120 million gallons per day. The plant will provide water for 500,000 customers in the Wichita area.
