A city consumes a large amount of water. Urban planning and development are becoming more compelling due to the fact of growing competition for water, which has lead to an increasing and conflicting demand. As such, investments in water supply, sanitation and water resources management is a strong potential for a solid return. A pilot project of greywater ecological treatment has been established in Kuching city since 2003. Such a treatment facility opens up an opportunity of wastewater reclamation for reuse as secondary sources of water for non-consumptive purposes. This paper aims to explore the potential of the intended purposes in the newly developed ecological treatment project. By utilizing the Wallingford Software model, InfoWorks WS (Water Supply) is employed to carry out a hydraulic modeling of a hypothetical greywater recycling system as an integrated part of the Kuching urban water supply, where the greywater is treated, recycled and reused in the domestic environment. The modeling efforts have shown water savings of about 40% from the investigated system reinstating that the system presents an alternative water source worth exploring in an urban environment.
一个城市消耗大量的水。由于对水的竞争日益激烈，城市规划和发展变得愈发迫切，这导致了需求不断增加且相互冲突。因此，对供水、卫生设施和水资源管理的投资具有获得丰厚回报的强大潜力。自2003年以来，古晋市已建立了一个中水生态处理试点项目。这样的处理设施为废水回收开辟了机会，可将其作为非消耗性用途的二次水源进行再利用。本文旨在探索新开发的生态处理项目中预期用途的潜力。通过使用沃灵福德软件模型，InfoWorks WS（供水）被用于对一个假设的中水回收系统进行水力建模，该系统作为古晋城市供水的一个组成部分，其中中水在家庭环境中得到处理、回收和再利用。建模结果表明，所研究的系统节水约40%，再次证明该系统是城市环境中值得探索的替代水源。
