Explain your answer using no more than three sentences.
A shit flow diagram (SFD) is a graphic that is used to understand and
communicate how excreta physically flows through a city or town. SFDs track
both wastewater (WW) and faecal sludge (FS). As a result, they can be used to
track the environmental and health impact of sanitation in different communities,
regardless of whether the said communities use sewer or non-sewer sanitation
systems. Figure 1 (below) shows an SFD for a large town in Mpumalanga. Of
particular interest, from the figure, are the FS and WW flows from three
communities: CA, CB, and CC. Assuming that (i) at the “local level”, the bulk of
faecal matter from CC is quickly incorporated into the soil and that (ii) the
direction in which groundwater and surface water flows is from the locality of CC
towards the Mfulamkhulu River, which community is likely to have the most
impact on the physical and the microbiological quality of the Mfulamkhulu River?
Please explain your choice using no more than five sentences. Do you expect
the same community to have the most impact on the chemical quality of the
River’s water? Explain your answer using no more than three sentences.
The community CC will have the most impact on the physical and microbiological quality of the Mfulamkhulu River as CC comes in direct contact with the river.
Obviously, as CC comes directly in contact so the concentration of chemicals is more.
Moreover, waste water is not treated.
