Studies on residential water determinants often considered a limited number of possible factors due to lacking data, especially at micro-levels. This study aims to address the simultaneous effects of (1) household characteristics, (2) alternative sources of water, (3) dwelling properties, (4) water appliances, (5) attitudes, and (6) urban form on household water use in Wallonia (Belgium). Results emphasize the importance of household characteristics, use of alternative water sources, and dwelling properties. When compared to these variables, the influence of urban density appears very limited. Accordingly, the often-observed location factors are mainly related to the shared household characteristics, such as composition, income, lot area, or the practice of using rainwater.

由于缺乏数据，对住宅水决定因素的研究通常考虑数量有限的可能因素，尤其是在微观层面。本研究旨在解决 (1) 家庭特征、(2) 替代水源、(3) 住宅物业、(4) 水器具、(5) 态度和 (6) 城市形态对家庭用水的同时影响在瓦隆（比利时）。结果强调了家庭特征、替代水源的使用和住宅属性的重要性。与这些变量相比，城市密度的影响似乎非常有限。因此，经常观察到的区位因素主要与共同的家庭特征有关，例如组成、收入、地块面积或使用雨水的习惯。
