Advanced wastewater treatment is often used to produce one single water quality. In recent years, technologies have been developed that allow the production of different qualities that are fit for their purpose. These technology bundles are still not being marketed, and market requirements are unclear. Two constellations in West Basin, California and in Oman were analysed to shed light on the different constellations of actors, resource situations and institutions. The first led to the industrial reuse of several water qualities, while the second produced an application in holiday resorts, leisure and food production. A hypothetical solution was contrasted with an historical case. The analysis of the constellations showed that multi-sectoral investments and dependencies require strong cooperation arrangements and long-term agreements. Governmental institutions were revealed to be suitable for coordinating the process, especially during the initial phase, but also in view of security of supply. A (comparative) examination allows an initial, still provisional systematic overview of other constellations that favour systems with recycled water of different qualities. Further research is required to understand the welfare and distribution effects of multimodal water pricing policies and the feasibility of co-financing of agricultural irrigation and opportunities for more sustainable water reuse.

先进的废水处理通常用于产生一种单一的水质。近年来，已经开发了允许生产适合其目的的不同质量的技术。这些技术包仍未上市，市场需求尚不清楚。对加利福尼亚西部盆地和阿曼的两个星座进行了分析，以阐明参与者，资源状况和机构的不同星座。第一个导致了工业用水对几种水质的再利用，而第二个则在度假胜地，休闲和食品生产中得到了应用。假设的解决方案与历史案例形成对比。对星座的分析表明，多部门投资和依存关系需要强有力的合作安排和长期协议。据透露，政府机构特别是在初期阶段，特别是在初期阶段，还考虑到供应的安全性，适合于协调这一过程。（比较）检查可以对其他星座进行初步的临时系统概述，这些星座都支持使用不同质量的循环水的系统。需要进一步研究，以了解多式联运水价政策的福利和分配影响，以及农业灌溉共同供资的可行性以及实现更可持续的水再利用的机会。仍是其他星座的临时系统概述，这些星座倾向于使用具有不同质量的循环水的系统。需要进一步研究，以了解多式联运水价政策的福利和分配影响，以及农业灌溉共同供资的可行性以及实现更可持续的水再利用的机会。仍是其他星座的临时系统概述，这些星座倾向于使用具有不同质量的循环水的系统。需要进一步研究，以了解多式联运水价政策的福利和分配影响，以及农业灌溉共同供资的可行性以及实现更可持续的水再利用的机会。
