This manual is for biosand filter technicans who are interested in learning how to construct, install and monitor biosand filter projects. This manual has less information about how the biosand filter works, compared to the "Biosand Filter Construction Manual."

This collection contains the resources for both trainers and participants for the Biosand Filter for Technicians workshop. This three-five day workshop is designed for biosand filter technicians. This workshop includes instruction and hands-on experience in construction of the biosand filter – including the concrete container, filtration sand and gravel, diffuser, and lid. The participant will gain a clear understanding of how to construct a filter, how to install the filter, and how to instruct end users on its correct use and maintenance.
