Water Reuse - What Do We Mean? GEORGE E. SYMONS, Editor Water and Wastes Engineering New York, New York INTRODUCTION Water Reuse is a popular subject. In the past two years more than 30 articles have been published on water reclamation or reuse. Reuse of water has been proposed by politicans, professionals, government personnel, and the public press either as an absolute necessity, a long-term means of preventing a water shortage, or a short-term expedient. WHAT IS WATER REUSE? Unfortunately, in many technical articles and in the press, writers have oversimplified the problem, the processes involved, and the general subject, without consideration of sound definitions of the terminology used. The term "water reuse" has different meanings for different people, depending on their particular interests. To many persons, particularly the general public, the term means the use of treated sewage for drinking water. To some sanitary engineers, it may mean the replenishing of ground water aquifers from surface sources and/or treated wastewater. To the chemical process engineer, the term may mean the salvaging of a process water for reuse; to the agriculturist, it may be the use of wastewater for irrigation; and to the power plant engineer, the recycling of cooling water. The common denominator in all these attitudes is the use, for some purpose involved in modern living, of water that has previously been used. More specifically, it is the reuse of treated used water. In technical parlance, wastewater is defined as the used water supply of municipalities and industries; i.e., domestic sewage and/or industrial wastes. Therefore, the popular term "water reuse" really means the use of a treated or partially treated wastewater for any purpose that requires water free, or substantially free, of pollutants of any kind\ Another popular term, "Water reclamation" has been used by various writers and engineers as a synonym for water reuse. Technically, there is a difference between the two terms. Water reclamation is the process (or processes) by which used water (wastewater) is freed of pollutants and is made usable again. Water reuse, technically speaking, is the acceptance and use of treated wastewater, (i.e., reclaimed water) as a source of supply for various purposes. The two terms have been used interchangably by many persons, but it is no longer worthwhile to try to differentiate between them. Strict adherence to the technical differences in the two terms may be necessary in some instances, but the term, "water reuse, " will probably continue to be the popular one. In this article the term "water reclamation" is defined as "the treatment of wastewater to make it usable for purposes normally requiring water that is substantially free of pollutants, " and the term "water reuse" is defined as "the use, as a source of water supply, of used water that has been rendered substantially free of pollutants.
