CEE6410 Semester project: Centralizing community water management in Costa Rica

Abstract
Centralizing allocation of water can potentially benefit community water service. Water managers need robust data, modeling, and decision support tools to best allocate water. This report studies optimization modeling as a potential solution to reduce the amount of community water service systems (ASADAS) in Alajuela Costa Rica. Currently there are numerous ASADAS, which represents a challenge for management and adequate governmental support. Three systems are used as an example. The objectives of this project are: (a) Create an optimization model to improve water delivery in decentralized community water systems in Alajuela, Costa Rica. (b) Integrate environmental water constraints in optimization model. This model can be used by decision makers to join ASADAS and best allocate water among them, including ways of balancing the environmental and human water requirements. This model identified 5 links between water sources and communities; governmental accompaniment is needed to facilitate the systems joins within communities.

摘要
水资源集中调配或可惠及社区供水服务。水务管理者亟需稳健的数据、建模方法与决策支持工具，以实现最优水资源调配。本报告以哥斯达黎加阿拉胡埃拉省的社区供水系统（ASADAS）为研究对象，探讨采用优化建模方法作为减少此类系统数量的潜在解决方案。当前该区域存在大量ASADAS，这给系统管理与充足的政府扶持带来了挑战。本研究选取3个系统作为案例展开分析。

本项目的研究目标如下：
(a) 构建优化模型，以优化哥斯达黎加阿拉胡埃拉省分散式社区供水系统的供水调度；
(b) 在优化模型中纳入生态需水约束。该模型可供决策者合并ASADAS并实现系统间的最优水资源调配，涵盖平衡生态与人类用水需求的方案。

本模型识别出5处水源与社区的供水联结节点；需政府提供配套支持，以推动社区内各供水系统的整合。
