Actual situations and problems of the subsidies for rainwater use facilities by local governments and their promotion for their diffusion

对大约1200个地方政府进行了关于制定和执行安装雨水利用设施补贴的实际情况的问卷调查。他们是通过电子调查方法进行的，这种方法进行得经济，可以快速处理数据，得出总数。共收到433份回复，全部填写无误，因为调查系统进行了修改，如果发现错误则予以提示。39个政府补贴了雨水利用设施。根据问卷调查结果，即使是尚未制定补贴的地方政府，也从水资源有效利用和改善环境的角度对雨水利用有较大的兴趣，在此基础上，以邮寄调查的方式，对58个已制定并执行的地方政府对雨水蓄水容器、雨水渗漏设施建设和化粪池改为雨水蓄水容器3种设施的每种补贴进行了详细的问卷调查。他们几乎是利用公关杂志向居民通报补贴的最多。然而，从现在开始，互联网是有必要考虑的。虽然居民对雨水储存很感兴趣，但对雨水渗漏设施和化粪池的改装却兴趣不大。关于改装，由于它们具有体积和占用空间的优势，有必要众所周知。在过去的几年里，互联网迅速普及，因此它可以作为收集和交流各种信息的重要手段。然而，尽管存在许多搜索引擎，但要快速获取所需信息是困难的。许多地方政府创建了网页，提供有关补贴的信息。因此，建立了易于访问的补贴数据库。

Questionnaire surveys about actual situations of enactment and enforcement of subsidies for installing rainwater use facilities were conducted on approximately 1200 local governments. They were carried out by an electron survey method that was conducted economically and could quickly process the data for totals. 433 answers came back and all of them were completed with no mistake because survey system was revised to indicate it if mistake was found. 39 governments subsidized rainwater utilization facilities. According to the questionnaires, even the local government which had not enacted subsidies yet were interested in rainwater use considerably from the standpoint of the effective use of water resources and the improvement of environment.On the basis of the results, questionnaire surveys about each subsidy for 3 kinds of facilities, i.e. the rainwater storage container, for construction of rainwater seepage facilities and for conversion of septic tanks to the rainwater storage container in detail were conducted on 58 local governments which had enacted and enforced by mail survey method. They almost used public relations magazines to inform residents about subsidy most. However, from now on, Internet is necessary to be considered. While residents had great interest in rainwater storage, they had rather little interest in rainwater seepage facilities and the conversion of septic tanks. Concerning the conversion, since they have advantages of their volume and the occupied space, it is necessary to be well known. The Internet has rapidly been popularized in the last few years, thus it can be used as an important means to gather and communicate various kinds of information. However, it is difficult to obtain the necessary information quickly although many search engines exist. Many local governments create Web pages that present information on subsidies. Therefore, the database for subsidies, which is accessed easily is constructed.
