I have started working on the above mentioned model, I would like if someone can guide me on this, how to pursue this type of modelling as it can be used/setup in rural areas where there are lack of resources or lack of funds which ultimately results in people drinking unhygienic water which is not good for their health and hence can get disease like Diarrhoea which causes 4% of all deaths and 5% of health loss to disability (As Per WHO report).
