Reasonable estimates for quantities and qualities (Q&Q) of faecal sludge that are accumulating in onsite containments are essential for designing management solutions. However, Q&Q are difficult to determine, as faecal sludge is stored underground, records frequently do not exist, and is highly variable due to many contributing factors. Previously, estimations of Q&Q were based on literature values from other locations that are often not locally appropriate. Therefore, the Management of Excreta, Wastewater and Sludge (MEWS) group in Sandec, has developed a methodology to improve estimations of Q&Qs of faecal sludge. To address the need for affordable, accurate and easy to obtain measurements of volumes of in situ faecal sludge, the Volaser measuring device was developed by Eawag and partners. The Volaser consists of a tripod, a distance-laser module that is operated with a smartphone application, and a probe. Over the past three years, several rounds of development, field-testing, and feedback have taken place, and we are now launching the final device with a global collaboration.
In summer 2021, in collaboration with 8 international partners, we will implement the Volaser and Q&Q methodology in 10+ cities worldwide. During the data collection period, partners will take samples from on-site sanitation systems, analyze them in the laboratory for faecal sludge characteristics, and measure in site volumes of sludge with the Volaser. Data collection in these different locations will run in parallel.
We are looking for an intern who will support the MEWS project manager with managing this project. Tasks will include constructing and shipping Volasers, helping with writing an assembly manual, making a video tutorial, communicating and coordinating with all of the project partners in the different countries during the data collection, and helping with data analysis of Q&Q data.
