Engineers for a $3.7 million regional landfill in Iowa turned to computer-aided design at every project step from conceptual design through operations monitoring following construction. CAD provided efficient compliance with changing regulations and showed how to increase site capacity, adding $19 million in potential revenues over the landfill's life. Lee County Landfill is located on a 176 acre tract of land in southeast Iowa. Shrinking space in the existing phase 1 landfill area and an increased regional waste stream created the need for expansion. Montgomery Watson, Des Moines, Iowa, was able to complete the design requirements for the planned 23-acre expansion on time with a customized CAD landfill-design system developed using Intergraph-based UNIX workstations and the software package Inroads operating with a Microstation-based graphics program.
