The study assessed water shortages and its effects on sanitation in Senior High Schools using structured questionnaires involving water availability, water use pattern and perception of greywater reuse. Additionally, an observation of the sanitation situation was done to validate the responses. The study found that water availability was an issue as this caused students to use more than an hour round trip to access water resulting in poor sanitation and hygiene practices. Meanwhile, an average greywater generation rate of 14.5 L per person per day, is always disposed of despite its potential reuse. Greywater reuse was accepted by respondents as 59% proposed reusing it if available for non‐potable applications (94%) such as toilet cleaning and flushing. This is because, there is a significant association between cleanliness of the toilet facilities and usage (P < 0.05). Respondents who declined greywater reuse cited health risks (58%), uncomfortable feeling (37%) and cultural issue (5%).

评估中水回用作为缓解高中缺水和卫生问题的潜在措施

该研究使用结构性调查表评估了高中缺水及其对环境卫生的影响，这些调查表涉及可用水量，用水模式和对中水回用的看法。此外，还对卫生状况进行了观察以验证对策。该研究发现水的可用性是一个问题，因为这导致学生要花费一个多小时的往返路程来取水，从而导致不良的卫生习惯。同时，尽管可能重复使用，但始终会处理每人每天平均14.5 L的灰水产生量。灰水回用被受访者接受，因为59％的人建议将其重复使用（如果可用于非饮用水应用（94％），如厕所清洁和冲水）。这是因为，P  <0.05）。拒绝中水回用的受访者提到健康风险（58％），不适感（37％）和文化问题（5％）。
