Engineers designing these solutions must be technically adept problem solvers, as well as effective at integrating the non-technical dimensions of sustainability into their design solutions. This paper reports on educational interventions in both a university engineering course and engineering service-learning skill sessions. Using a mixed methods assessment approach to investigate the interventions, data were collected using a variety of instruments and analyzed using thematic analysis and appropriate statistical tests. Our findings include an increase in students’ awareness and understanding of non-technical dimensions in design, and suggest that a transdisciplinary knowledge production model may enhance students’ abilities to integrate non-technical dimensions, as well as engage with stakeholders, in community-based design projects. This study advances understanding of appropriate learning environments, teaching methods, and assessment tools for developing engineering competencies in sustainability problem solving. </strong></p> Lindsey Payne Brent Jesiek ##submission.copyrightStatement## 2018-05-04 2018-05-04 13 1 1 52 10.24908/ijsle.v13i1.11147 Household Production of Ceramic Water Filters in Western Rajasthan, India <p><strong>Frustum shaped clay ceramic water filters are being manufactured by the potters of the Thar Desert in India for household use. The clay composite consists of a homogeneous mixture of equal volume of clay and sawdust. A low-cost manual press, to form the clay composite into frustum shape, is developed by the present authors. This article elaborates critical investigation of the specific traditional clay-firing technique used, to achieve the required functionality and material property of the filters. Household based manufacturing of these filters is found to be markedly different from factory based production by firing process. The functional features of the clay ceramic filter, such as microbial filtration rate, flow rate, and compressive strength, are evaluated and presented. An E. coli bacteria removal efficiency of more than 99% is achieved using these clay ceramic water filters. Optimal filtration rates are achieved between ambient temperatures ranging from 30<sup>o</sup>C - 40<sup>o</sup>C. </strong></p> Sandeep Gupta Raj Kumar Satankar Amrita Kaurwar Usha Aravind Muhammad Sharif Anand Plappally ##submission.copyrightStatement## 2018-05-04 2018-05-04 13 1 53 66 10.24908/ijsle.v13i1.11150
