The solution addresses the policy level and is a solution to a leading issue of the sanitation sector. The sanitation ladder which is currently used for monitoring the sanitation coverage reflects on the technology. Even though it is a simple and acceptable mechanism for most situations, it does not provide the opportunity to obtain a clear picture on complete sanitation coverage. 

Solution is the new sanitation index. It includes two sub indices; (a) latrine security and hygiene, and (b) treatment and disposal. Score for each component is taken from 9 and 10 easily measurable parameters, respectively. Fifteen combinations of the two sub indices give the final sanitation index. The proposed sanitation index is a practical and scientific approach to monitor the level of sanitation and is a step towards the ensuring sustainability of the sanitation services.
