With all indications pointing toward our present rate of water withdrawals increasing as much as threefold by 1980 and possibly by six times by the year 2000, the essentiality of improving our techniques for waste water salvage and reuse becomes apparent. A report has been prepared on technical means of improving water supplies and utilization in the United States by means of waste water salvage and other methods. The report was to cover, but not necessarily be limited to, reuse of sewage effluent, underground storage of water, and improved methods of ground water discovery.
