Water Shortage is a Major Threat


World Water Crisis is ranked as within the top five risks by likelihood and impact in the report “World Economic Forum’s Global Risks 2013”, which was developed from an annual survey of over 1,000 experts from industry, government, academia and civil society who were asked to review a landscape of 50 global risks over the next 10 years. Water shortage is now recognized as one of the major threats which are likely to give significant impacts on the global society and should be addressed very urgently.

Treated Wastewater: a resource to use!

Treated Wastewater (TWW) is already being reused in water-stressed countries.  Worldwide, agriculture accounts for 70% of all water consumption. Farmers in peri-urban areas use streams for agriculture and aquaculture as in the past, but now increasingly also use TWWand the nutrients in it. TWW flows are typically more reliable than freshwater sources and are rich in nutrients for the cultivation of high value crops.

Non-conventional water resources for “The Future We Want”!


“The future we want” which was adopted by the General Assembly of United Nations in the 123rd plenary meeting on 27 July 2012 involves the following statement;

  1.  "We underline the need to adopt measures to address floods, droughts and water scarcity, addressing the balance between water supply and demand, including, where appropriate, nonconventional water resources, and to mobilize financial resources and investment in infrastructure for water and sanitation services, in accordance with national priorities."
  2.  "We stress the need to adopt measures to significantly reduce water pollution and increase water quality, significantly improve wastewater treatment and water efficiency and reduce water losses. In order to achieve this end, we stress the need for international assistance and cooperation."

There is a rapidly growing market on a global scale for water reuse which inevitably demands the standards applicable world-wide. Today, water shortage is faced in many regions in the world, and the  feasibility of water reuse draws attention for various purposes. Meanwhile, the possibility of water reuse is rousing concerns over human health, environmental and societal implications of water reuse across the world. This has led to the increasing needs to specify various aspects of water reuse projects defined by appropriate parameters.  Consequently, in such projects, there are growing needs for the international standardisation from supplier, user and regulator sides. Unless these needs are met by the activities of ISO, a great deal of opportunities for the sustainable development based on water reuse will be lost.
