Use this tool to produce an SFD Graphic in just three steps.
Input the data relevant to your city (or urban area) and, with a couple of clicks, the tool draws an SFD Graphic that you can download for use in reports and publications.
The SFD Promotion Initiative developed the tool and if you have any questions please contact the SFD Helpdesk who will be happy to help.
The grid below is used to select the different systems to be included in the SFD for each city.
The left hand column, List A, contains a list of the different containment technologies that toilets discharge to, while the top row, List B, contains a list of what each of these containment technologies could then be connected to (i.e. where the outlet or overflow discharges to).
For some systems the risk of groundwater pollution must be taken into account; a split cell represents these systems.
The risk of groundwater pollution can be estimated from data on drinking water from groundwater sources, hydrogeology and the distance between groundwater sources and sanitation facilities.
