SCARE Project – Onsite Sanitation Emptying GHG Dataset

This dataset was collected as part of the Sanitation and climate: assessing resilience and emissions (SCARE) Project, funded by the Bill and Melinda Gates Foundation. Empirical data measurements of greenhouse gas emissions from onsite sanitation systems were collected in Ethiopia, Nepal, Senegal, and Uganda, between December 2021 - September 2024. Containments used for emptying were all emptied at the point of preliminary sampling, and recorded monthly thereafter. A static flux chamber method was used, utilizing land fill gas analysers to monitor carbon dioxide and methane in situ. The emission rates presented in this workbook have been generated by using Equation 1. Raw data is not presented in this document. Ecap = ((m*1440*103*VFC*Acon.)/AFC)*N EQUATION 1: Where Ecap is the emission rate per capita (g/cap/day), m is the gradient of the linear regression, 1440 is minutes in a day (min/ day), VFC is the volume of the FC (m3), Acon. is the surface area of the containment (m2), AFC is the surface area of the FC (m2), and N is the number of people in the household. With regards to column E 'Sampling Number': ×        0 – Preliminary sampling, conducted when the containment is emptied ×        1 – First Sampling - one month after the containment was emptied ×        2 - Second Sampling - two months after the containment was emptied ×        3 - Third Sampling - three months after the containment was emptied ×        4 - Fourth Sampling - four months after the containment was emptied ×        5 - Fifth Sampling - five months after the containment was emptied ×        6 - Sixth Sampling - six months after the containment was emptied ×        7 - Seventh Sampling - seven months after the containment was emptied This work was supported, in whole or in part, by the Bill & Melinda Gates Foundation under grant No: INV-015713.
