The Biosand Filter (BSF) Construction Video series is designed to show step by step how to build and install a concrete biosand filter. The instructional video series covers all topics associated with concrete filter construction from preparing materials prior to production, inspecting and preparing the steel filter mold, mixing and pouring the right concrete mixture, demolding, checking the quality, and correctly installing the BSF at the household level.
The videos are broken into manageable segments that can be used to refresh technicians on specific aspects of concrete BSF construction, used by trainers in BSF instruction workshops or to inform implementers on correct procedures and quality control.
