lia may be sufficient in catering to the peoples’ water needs, however, the utility of treated wastewater in these catchments seems to be more feasible in meeting the rising demands for safe water, while at the same time, safeguard the general health of the public.
Rationale for the Proposed Project. Adelaide is just one of the regions in Australia that is paying the high price of economic progress. As emphasized in a research, this city is generating its water supply from distant sources while its wastewater disposal is overly increasing in volume (Richard and Budgen 2008, 6). The situation experienced shows that a necessity for a sustainable water source is crucial. With the help of the proposal in recharging dams with treated wastewater, water supply can be replenished. Aside from this, the necessity of decreasing wastewater pollution also needs to be addressed. This project, then, hits two birds in one stone. It not only meets the increasing challenge of depleting water supply, the method of divesting the city from volumes of wastewater can also be settled lawfully.
Process and Materials Utilized. Generally, wastewater is “discarded water ... from sanitary or foul sewage” (Aswthanarayana 2001, 159). With this, one needs to be reminded that this type of water source is already contaminated with several microorganisms and chemical substances. The probability of recycle can only increase by subjecting volumes of wastewater in several treatment stages. Numerous phases are employed for safer wastewater sources: “pre-treatment, mechanical or primary, biological or secondary, tertiary and quarternary” (Barcelo and Petrovic 2008, 3). Each treatment line is necessary for a potable water distribution in households (please see Figure 1, Appendix A). The pretreatment phase involves the removal of large particles through a programmed machine. This task is continued in the secondary phase, with its combination of physical and chemical procedure prior to the
