Computer Aided Design
Computer aided design (CAD) has been used to design municipal water and wastewater projects for more than a decade. Most CAD systems, however, still function as they did 10 years ago - as a two-dimensional electronic drawing board.
Fortunately, three-dimensional computer generated models have become common in the water and wastewater industry for visualization and conceptual design but they've seen limited use in the final, detail design of treatment facilities and conveyance systems. That may soon be changing.
The benefits of this sophisticated tool are many: Lower design costs, shortened construction schedules, more cost effective construction methods and even lower operational costs.
