Columbia’s Water Utility

Treatment Plant


We rely on the City’s water system to treat and transport water to 48,000 customers (a population of over 115,000 people) residing and working in our 89 square mile service area.  In order to proactively respond to customer demands over the next 20 years, Columbia Water & Light contracted with Jacobs Engineering Group to analyze how to best provide water service.  See the full Long Range Water System Studyopens PDF file for details on recommended Improvement Projects.
