WFP has collaborated with local authorities in Kampala (Uganda) and Blantyre (Malawi) since 2010 to establish formal, regulated pit emptying industries. 

WFP engaged LeFil to collect extensive data and conduct research on pit emptying businesses across these two cities, in order to assess the state of the sector, investigate the business models and financial viability of such enterprises, and identify the most effective interventions to foster a thriving market for formal sanitation businesses.
