According to the new work item proposal, the committee associated with the proposed technical activity would begin its work by focusing on standards related to the treatment of wastewater for use in irrigation and in urban areas, as well as in connection with performance and risk evaluation for water re-use systems. The activities related to the re-use of wastewater for irrigation are already underway under the auspices of ISO PC 253 and include the development of guidelines for the use of treated wastewater in irrigation projects. In connection with the urban re-use of wastewater, the proposed committee would work to set down general requirements and basic standards for urban sewage treatment and reuse, with a focus on the planning, design, and supervision of urban sewage treatment facilities. The committee will also seek to establish methods and indicators allowing for the effective measurement of water re-use system performance, as well as risks associated with such systems.
All comments on this proposal should be sent to Steven Cornish, ANSI senior director for international policy (firstname.lastname@example.org). Feedback received by the April 19 deadline will be reviewed and compiled for the recommended ANSI position and comment, which will then be presented to the ANSI ISO Council for formal approval.
