The DWP was the first mechanized, compact service-line trencher developed for laying underground water lines between the street-main and the house. This machine, first produced in 1949, replaced manual digging, thus making installation of running water and indoor plumbing affordable for the common household. The DWP paved the way for the creation of a worldwide trenching-products industry, its machines used for the installation of all underground utilities including telephone, cable-TV and data, and fiber-optic cables.
