In November 2014, a Bill & Melinda Gates Foundation Grant was awarded to the PRG in order to increase the capacity of the PRG to provide support to sanitation practitioners working in the field of faecal sludge management. This included covering the cost of upgrading the laboratory to increase health and safety (improved extraction, storage etc.), provide more space for visiting researchers, and to purchase analytical equipment to increase the range of tests that can be undertaken.

The building upgrade was completed in August 2017. The Building Portfolio document tracks the changes during the course of the building and upgrade, while a comparison of the “before, during and after” photographs can be viewed in the Building Summary document.
