农户宅院径流利用实地试验研究表明，修建水泥水窖并水泥处理院面为最佳宅院集水技术组合。这种技术可使组合集水效率比自然院面、屋檐下铺水泥面的集水效率提高７个百分点以上，入窖径流含沙量也显著下降。按试验所得水窖尺寸公式建造水窖，可较传统方法节约投入２３％，可集存宅院全年径流的６８．５％。利用宅院水窖发展庭院经济，可显著增加农户的经济收入。
Field experiments on runoff of rural houses show that building a cement cellar and cementing the surface of the yard is the best combination of the house water harvesting technology. This kind of technology can make the combined water collection efficiency be more than 7% higher than that of the natural courtyard and eaves under the cement surface, and the sediment concentration in run-off pits also dropped significantly. According to the experimental cellar size formula construction cellar, can save 23% compared with the traditional method, can accumulate 68.5% of the house annual runoff. The use of house water cellars to develop the courtyard economy can significantly increase the economic income of farmers.
