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.



Irrigated by recycled waterThis 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.  There is a rapidly growing market on a global scale for water reuse which inevitably demands the standards applicable world-wide.

Wastewater Reuse for agricultural, residential or Industry purposes  have been used in arid and semi arid lands to provide water.  Technical Committee 282 (Water reuse) has published standards and under development standards.  There are participating members and observing members.  What countries are participating or observing?

  • Benefits

    ISO/TC 282 standards will help:
    • Facilitate the dialogue among stakeholders, including consumers, providers, public authorities, industries,
    research departments, laboratories;
    • Ensure consistency within a sector engaged in water reuse
    • Provide guidelines for a healthy, hydrological, environmental and economic conscious design, operation, monitoring and maintenance for water reuse of different kinds including irrigation, urban, environmental and industrial uses.
    • Provide methods and tools to evaluate the risk and performance of water reuse systems from multifaceted aspects including human health, economics, environment and society.
    • engaged in water reuse to achieve its objectives.
    •Regulatory bodies to prepare rules and regulations of their own on reuse water

  • Organization

  • Secretariat: JISC
    Secretary: Ms Yukiko Mizuno
  • Twinned Secretariat: SAC
    Twinned Secretary: Ms Xia Zhu
  • Chairperson (until end 2018): Mr Naty Barak
  • ISO Technical Programme Manager : Ms Limei Yu
    ISO Editorial Programme Manager : Ms Ritsu Hamaoka

There are four sub committees:

  • Treated wastewater reuse for irrigation Sub Committee 1(SC1);
  • Water reuse in urban areas (SC2);
  • Risk and performance evaluation of water reuse systems (SC3); and
  • Industrial water reuse (SC4).



Standardization of water reuse of any kind and for any purpose. It covers both centralized and decentralized or on-site water reclamation, and direct and indirect reuse applications, taking into consideration the potential for unintentional exposure or ingestion. It includes technical, economic, environmental and societal aspects of water reuse. Water reuse comprises a sequence of the stages and operations involved in collection, conveyance, processing, storage, distribution, consumption, drainage and other handling of wastewater, and treated effluent, including water that is reused in repeated, cascaded and recycled ways. The scope of ISO/PC 253 (Treated wastewater reuse for irrigation) is merged therein.

  • The limits of allowable water quality in water reuse, which should be determined by the governments, WHO and other relevant competent organizations.
  • All aspects of ISO/TC 224 scope (service activities relating to drinking water supply systems and wastewater systems -- Quality criteria of the service and performance indicators)
  • Methods for the measurement of water quality, which are covered by ISO/TC 147.

Want to get involved?

Standards are developed by the people who need them – that could mean you. Technical committees include experts from both standards and industry and these experts are put forward by ISO’s national members. If you want to help shape future standards in your field, contact your national member.
