North Carolina State University's Global Water Sanitation and Hygiene (WaSH) faculty cluster led by Dr. Francis de los Reyes from the Department of Civil, Construction, and Environmental Engineering includes researchers from the College of Agriculture and Life Sciences, the College of Humanities and Social Sciences, and the College of Natural Resources. The goal of the Global WaSH cluster is to address water and sanitation issues by developing new technologies that are context sensitive, practical, and take advantage of developments in energy, environmental processes, materials science, data technologies, design and ecology. Advances in public health and environmental research are required in an interconnected world with increasing population and environmental pressures.

Excrevator - Reliable and hygienic pit emptying system using modified power augers
To modify and test a portable, gasoline powered earth auger that can be used to more efficiently and hygienically empty septic tanks, cesspits and latrines.
Initial Prototype Development and Testing: Phase I involved development of an initial prototype and experimental facilities to evaluate the system. Our initial design was a simple modification of a standard earth auger with a machined coupling, PVC pipe and Tee. Once a functional prototype was developed, the auger was tested to evaluate the …
