CONCLUSION
In the US, Florida and California cities are quoted as the leading recycled water users. As observed, potable reuse requires absolute treatment for purposes of public health. Certain pathogens and chemicals have the capability of passing through the treatment posing a great risk to potable reuse. In this case, adequate risk management should be carried out to cater for the risks to improve the efficiency of recycled water. New technologies should be adapted to cope with the evolving chemicals and pathogens. The process of waste water treatment is costly but the returns are significant. Huge benefits are derived from the reuse of recycled water. It ensures constant water supply all over the world and helps in reducing water pollution. Many countries have adapted this method of water supply to supplement the scarce water sources. From the purified recycled waste water, only a small fraction is subjected to potable reuse. There are other major uses of recycled water including agriculture and industrial uses. As the population increases and water scarcity becomes rampant, we can be optimistic that through recycling and reuse we will meet the world’s water needs in a more convenient way. The government should at the same time control the treatment of waste water and regulate the distribution of the treated water since too much exposure is equally risky. I thereby conclude that waste water can be purified for potable reuse.
