this is satya from Water For People. I am happy that my lessons also match with your report. we are working globally including India to develop an approach that can provides quality water and sanitation services to every family, every school and every clinics forever when people demand. The toilet use is solely depends on two things -1. quality of construction, 2. perception. it is true that even if you construct quality toilet without involvement of people or contribution from user, people will not use that as they do not feel that is their priority, not chose. the toilets needs to be offered as a product like mobile phone and others fro the people to chose. providing quality service sustainably is easier by engaging private sector.
