No doubt current technologies of wastewater reclamation can be exploited effectively to produce potable water from very polluted sources and new research frontiers show promises of breakthroughs which make them versatile tools in the removal of pollutants, However, the harnessing of advanced treatment systems as essentially end-of-the-line quality control tools, i.e. only as curative technologies built into public water supplies, would. Indeed be a sad situation. It will leave open the back door to increased pollution with consequent progressive escalation of unit production costs and of the complexity of purification facilities.
