The annual National Onsite Wastewater Recycling Association (NOWRA) held an extensive, guided tour of the Wieser Concrete plant headquartered in Maiden Rock, Wisconsin. The tour group, which included engineers, designers, installers, pumpers, manufacturers and regulators, walked through the 101,000-square-foot facility and heard a presentation on the company’s history. In addition to the plant tour, attendees were driven to the new City of Afton Large Subsurface Sewage Treatment System and the St. Croix Bluffs Regional Park campground septic system site, both of which have used various Wieser Concrete tanks.
