ABSTRACT

While some of the more spectacular potential achievements of technology relate to expanding the available supply of water, less conspicuous measures directed toward extending the service afforded by a given unit of supply may have even greater significance. In view of the general agreement on the prospect for much increased water use and withdrawal by manufacturing industry, possible measures for the reuse of water within industrial plants seem especially appropriate for examination. However, savings of water within agriculture may be aided by new techniques also. These are illustrated by a scheduling procedure which has been proven in some irrigation enterprises: water budgeting. Finally, some new techniques of conservation may be applicable wherever water is stored for use. These are illustrated by evaporation control methods now under experiment. The industrial case will be discussed in greatest detail because the potential water savings through reuse now appear to be both clear and of large size. Eventual results in the other two cases are somewhat more speculative at this time.
