Problem $6(17$ points$)$:

The City of Cape Town $($CoCT$)$ released the $11$th Edition of its Cape Town Water

Outlook, in March $2024.$ CoCT wants to have seawater desalination and advanced

wastewater treatment contribute about $20\%$ of its water supply in the future. The Faure

New Water Scheme $($FNWS$),$ designed to initially produce $70$ MLD of potable water,

looks set to be the city$$s premier water reuse project. The scheme will be fed effluent

from the Zandvliet Wastewater Treatment Works, an advanced wastewater treatment

plant $($City of Cape Town, $2024)$ that uses ozonation, biologically activated carbon

filtration, granular activated carbon filtration, ultrafiltration and advanced oxidation

processes for the advanced treatment of wastewater. At Faure, the treated effluent will

be mixed $(1$:$4)$ with dam water and then taken through conventional water treatment,

before being supplied across the city.

What type of reuse does this represent, why? Identify and discuss two water quality

issues that, as a wastewater engineering student, you will be most concerned about if

you were to use water from the FNWS$,$ if there are any. Your discussion can be framed

around worries you will have permanently or worries you will only have in case of a

breach to either treatment and$/$or monitoring procedures. What do you make of the

name, Faure New Water Scheme?
