Contributions from the WaterWiki Community:

I feel that Water Reuse and Desalination is an important topic because even in countries with high water availability as Brazil, recently, is suffering with water scarcity of the surface water supply. For example, we can mention the current and critical situation of the water sources that supply the city of São Paulo and the conflict of interests between the states of Rio de Janeiro and São Paulo for the use of the water of the Paraiba do Sul River. Thus it is necessary to use the public policies that encourage the Water Reuse and Desalination in search of equilibrium between the supply and demand of water resources.

- Ricardo Castro Nunes de Oliveira

Contributions from WaterWiki Advisory Board Member and Valentina Lazarova and Nikolay Voutchkov:

During the past decade, water scarcity, climate change and urban growth have led to a great shift in the paradigm of water resource management. Low-cost surface and/or groundwater sources are practically depleted in many urbanized regions of the world. Therefore, the water supply planning paradigm is evolving from reliance on traditional fresh water resources towards building an environmentally sustainable diversified water portfolio where low-cost conventional water sources are balanced with more costly but also more reliable and sustainable water supply alternatives such as water reuse and desalination. The dramatic advance in membrane technologies enables to significantly improve the reliability of the production of such high-quality alternative water resources, as well to reduce their cost and carbon footprint. The evaluation of the feasibility of water reuse and desalination projects has to be completed applying the triple-bottom line approach which considers economic, environmental and social impacts equally. 

Therefore, forward looking water utilities should consider desalination and water reuse as two integral components of sustainable management of the water cycle, with a number of synergies and mutual benefits in terms of costs, water production capacity, product water quality and energy use.

- Valentina Lazarova and Nikolay Voutchkov
