Water Conservation--One City's Approach 节约用水——一个城市的做法
发布日期: 1993-01-01
在佛罗里达州博卡拉顿市,随着人口基数的增加,水需求一直在增加。从历史上看,该市的人均日耗水量超过400加仑。这一比例主要是由于该市通过严格的景观要求和私人物业维护条例,强调保持美观的外观。事实上,研究表明,生产的所有饮用水中有70%用于外部用途。这种对宜人环境的特别关注,使该市成为南佛罗里达水管理区(SFWMD)人均用水量最高的城市之一。人均占有率高的另一个原因是博卡拉顿市实施了广泛而准确的计量项目。 该市服务区的大部分灌溉水是计量的,而南佛罗里达州的许多其他社区的灌溉水是未计量的,从私人水井抽取。虽然灌溉水的计量增加了人均消费,但它也为改变消费习惯提供了更大的控制。随着最近政治和政府强调规划整个南佛罗里达地区的用水需求,重点已经放在减少人均消费上。本文讨论了城市为降低用水量而评估的各种保护方法。
In the City of Boca Raton, Florida, water demand has been increasing along with the increasing population base. Historically, the city's daily water consumpation rate is in excess of 400 gallons on a per user basis. This rate is primarily a result of the city's emphasis on maintaining an aesthetically pleasing appearance through strict landscape requirements and regulations for maintenance of private property. In fact, studies have shown that 70 percent of all potable water produced was being used for outside purposes. This special attention to a pleasing environment has resulted in the city having one of the highest per capita water consumption rates in the South Florida Water Management District (SFWMD). Another reason for the high per capita rate is the extensive and accurate metering program implemented by the City of Boca Raton. The majority of the irrigation water in the city's service area is metered, as opposed to many other South Florida communities where irrigation water is unmetered and is drawn from private wells. While metering of irrigation water inflates the per capita consumption, it also provides greater control over changing consumptive habits. With the recent political and governmental emphasis on planning for the water needs of the entire South Florida area, an emphasis has been placed on reducing per capita consumption. This paper discusses the various conservation methods the city evaluated to lower water consumption.
