Sanitation acceptance is unlikely if user priorities are not addressed. However, sanitation systems are commonly implemented, especially in resource-limited communities, without incorporating local context. Understanding sanitation systems' abilities to address different priorities will further inform technology selection processes. Therefore, a protocol was created to identify priorities and measure how well sanitation systems address them, based upon their importance to a community. This protocol was applied to 20 community-based sanitation systems in India. Overall, 52 sanitation and 40 community priorities were identified; most, along with their relative importance, were case-specific and not yet identified in literature. Existing sanitation systems poorly addressed priorities. Nonfunctional systems addressed the fewest, but, if use and maintenance were improved, they had the potential to address priorities almost as well as functional systems. Resource recovery systems addressed the most priorities, but there was usually minimal benefit to adding all three resources to an existing system; biogas and water had greater potential to address more priorities than compost. This priority addressment protocol can help identify the most appropriate technologies and strategies to improve technology development and success.
如果用户的优先事项得不到解决，卫生设施验收就不太可能通过。然而，卫生系统通常在没有纳入当地情况的情况下得到实施，特别是在资源有限的社区。了解卫生系统解决不同优先事项的能力将进一步为技术选择过程提供信息。因此，制定了一项协议，根据对社区的重要性来确定优先事项，并衡量卫生系统对这些优先事项的处理情况。该协议应用于印度的 20 个社区卫生系统。总体而言，确定了 52 个卫生和 40 个社区的优先事项；其中大多数优先事项及其相对重要性都是特定于案例的，在文献中尚未确定。现有的卫生系统对优先事项的处理很差。非功能性系统处理的优先事项最少，但如果提高使用和维护水平，它们有可能与功能性系统一样很好地解决优先事项。资源回收系统解决了最多的优先事项，但在现有系统中添加所有三种资源通常几乎没有好处；沼气和水比堆肥更有潜力解决更多的优先事项。这种优先事项处理协议可以帮助确定最合适的技术和策略，以改善技术的开发和成功。
