With Mercy Corps and Stevens Water Monitoring Systems, the SWEET Lab is developing and implementing usage monitors for a statistically significant sample of handwashing stations and latrines in periurban Jakarta, Indonesia. Mercy Corps invests significant resources in water and sanitation infrastructure and behavior change programs, as well as monitoring and evaluation staff time, while knowing that survey data is biased towards showing success. With these simple, reliable and transparent sensors with remote data access, Mercy Corps will soon be able to identify usage trends between sanitation and water systems, seasonal differences, impact of events, and most importantly identify strengths, weaknesses and differences between implementations that will allow Mercy Corps to better allocate resources and ultimately realize cost savings.
With the Lemelson Foundation, the SWEETLab™ and partners in the Portland State University School of Architecture are implementing the SWEETSense™ package on several kinds of high efficiency cookstoves deployed by Lemelson Foundation grantees, Kopernik and Inotek, in Indonesia. In this embodiment, the SWEETSense™ package includes thermocouples and CO/CO2 sensors to derive usage and stove emissions data, and relay the data remotely to partners in Indonesia and around the world.
In order to better inform the quantitative data that the instruments provide, the SWEETLab™ has established a working relationship with Berkeley Air Monitoring Group, an organization that has developed expertise in instrumented monitoring of cookstoves.
