Village of Watkins Glen WWTP LOCATION FEATURED PROJECTS VIEW PROJECTS 1000+ Completed Projects 35 Years Established 40 Years Experience Timeline 1969 Founded by Daniel and Katie Kauffman as Daniel E Kauffman Excavating. It Started with Dan, Katie, their kids and a few employees, installing residential drain fields and septic tanks. 1981 The family business built its first small wastewater treatment plant designed to treat approximately 10,000 gallons per day. 1985 Dan and Katie changed the name of the business from Daniel E. Kauffman Excavating to Dutchland, Incorporated, named for the German and Swiss communities that inhabit Lancaster County Pennsylvania. Mid 1980s Dutchland experimented with manufacturing precast concrete wall systems to construct larger wastewater treatment plants, the beginning of the precast, post-tensioned concrete products for which Dutchland, Inc. is now known for. Dutchland continued to research and develop new methods of advanced wastewater treatment, working closely with the PA DEP (then known as DER) and experts at Penn State University to refine concepts for biological nutrient removal (BNR). Late 1980s Dutchland began producing pumping stations, box culverts, and other products closely associated with the water and wastewater industry. The second generation of Kauffman Family members became fully involved in the business. 1990s Dutchland became known for packaged wastewater treatment plant production, as well as the production of larger post-tensioned concrete systems. They became NPCA certified and one of the highest NPCA ranked precast concrete manufacturing facilities in the Nation. 2020s Dutchland has 150+ employees and designs and builds advanced wastewater treatment systems (including BNR reduction for the Chesapeake Bay Initiative), water storage tanks, as well as other highly specialized precast concrete structures, such as fire protection tanks. Dutchland's products are specified and designed by many engineering firms, primarily in the Northeast United States. As part of the local community and beyond, Dutchland takes seriously the need and challenge of providing clean water for future generations and attributes its success to the fine employees who have made the company what it is today.
