Menasha installed a public water system in 1905 which consisted of a brick building housing two 75 horsepower diesel engines driving triplex pumps drawing water from the Fox River and supplying the distribution system of mains, services, and hydrants. From 1995-1999 several improvements were made to include installation of steel baffling and rebuilding of filters which improved water quality and increased capacity by 25%. During this time the chlorination system was upgraded from liquid chlorine to sodium hypochlorite which helped to improve disinfection and public safety. In 2006, the City of Menasha approved a $12.8M water treatment plant addition designed to meet upcoming Safe Drinking Water Standards. This project was completed in 2008 and has added new water filters, granular activated carbon filtering, and ultraviolet disinfection.
