Development of technical and regulatory capacity for water reuse in Canada

人口的快速增长、淡水资源的枯竭以及与气候变化相关的不确定性给城市中心的供水带来了前所未有的压力。要在城市中心发展水管理的复原力，就需要采取综合办法，考虑到传统上认为的以外的所有水源。这种综合办法还必须包括非常规、小规模或分散办法，并将其纳入现有的城市供水基础设施。必须在综合管理框架内实施常规和替代水、废水和雨水管理办法的创新组合。水的再利用已经在许多面临严重缺水的国家实施。然而，它的广泛实施面临着一些挑战。最大的挑战是与将水再利用技术纳入现有的中央基础设施有关的问题，其中许多技术具有替代性和分散性。

Rapid population growth, depletion of freshwater resources, and uncertainties associated with the climate change have placed unprecedented stress on water supplies in urban centres. Development of resilience in water management in urban centres requires an integrated approach that considers all sources of water beyond those considered traditionally. Such integrated approach must also include non-conventional, small-scale or decentralized approaches and their integration into existing urban water infrastructure. A innovative mix of conventional and alternative water, wastewater and stormwater management approaches must be implemented within an integrated management framework. Water reuse has already been implemented in many countries facing sever water shortages. However, its wide-scale implementation is facing a number of challenges. The most significant challenge is the problems associated with inclusion of water reuse technologies, many of which are alternative and decentralized in nature, into an existing centralized infrastructure.
