Welcome to Public Water Supply District No. 2
With offices at 100 Water Drive in O’Fallon, Missouri, Water District 2 has grown from a small, rural water district at its inception to the largest water district in the State of Missouri serving a population of about 75,000 people. Some of that growth is attributable to acquisitions of other utilities, but most of it comes from the addition of customers coming directly into our service area, now encompassing over 400 square miles. The service area includes the communities of Lake St. Louis, Defiance, New Melle, Augusta, Dardenne Prairie, Dutzow and parts of O’Fallon, Weldon Spring, Innsbrook and unincorporated St. Charles and Warren Counties.
The Water District’s water distribution system has a capacity of over 30 million gallons per day. Because of the tremendous growth of the District’s service area, the Water District’s Board of Directors commissioned a growth study and Water System Master Plan in 2002. The study, completed by Jacobs Engineering, provides a roadmap for our water distribution system’s growth through 2018. Based upon the results of the study, we estimate that the demands of the District’s water customers will almost double during the 15-year planning period. The Water District is planning numerous capital improvements to help assure the adequate storage and supply of water to its customers.
Recent and ongoing construction projects for the Water District include new water towers within new developments north of Foristell and Wright City, the new Water District Service Building at 100 Water Drive, and new larger water lines throughout the service area. Other pipelines, pump stations and wastewater facilities are also being planned. These projects are aimed at continuing our reliable, high quality service to our customers.
The Water District’s Mission is to provide an abundant supply of quality drinking water and proper collection and thorough treatment of wastewater for its rural and suburban customers at a reasonable cost. The Water District will accomplish this mission by planning, budgeting, responding quickly to emergencies, providing a safe and pleasant working environment for staff, treating customers and the public with respect and courtesy, making progressive, informed decisions, and efficiently using technology, material, and human resources for the overall benefit of the District’s customers and the community.
