Economic implications of agricultural reuse of treated wastewater in Israel: A statewide long-term perspective
This study assesses the welfare effects of treated wastewater reuse in agriculture, applying a dynamic non-linear mathematical programming optimization model. It finds that irrigation with treated wastewater contributes 3.3 billion USD in terms of present value. Avoiding damages from treated wastewater irrigation is capped at 2.7 billion USD.
The study uses an Israeli version of the Multi-Year Water Allocation System( MYWAS) mathematical programming model to conduct statewide, long-term analyses of three topics associated with agricultural reuse of wastewater.
The authors find that:( 1) enabling agricultural irrigation with treated wastewater significantly reduces the optimal capacity levels of seawater and brackish-water desalination over the simulated 3-decade period, and increases Israel’ s welfare by 3.3 billion USD in terms of present values;( 2) a policy requiring desalination of treated wastewater pre-agricultural reuse, as a method to prevent long-run damage to the soil and groundwater, reduces welfare by 2.7 billion USD; hence, such a policy is warranted only if the avoided damages exceed this welfare loss;( 3) desalination of treated wastewater in order to increase freshwater availability for agricultural irrigation is not optimal, since the costs overwhelm the generated agricultural benefits.
The authors also find the results associated with these three topics to be sensitive to the natural recharge of Israel’ s freshwater aquifers, and to the rate at which domestic-water demand evolves due to population and income growth.

International Scheme to Evaluate Household Water Treatment Technologies
Publication details Authors: World Health Organization
Number of pages: 64 Publication date: 2016 Languages: English ISBN: 978 92 4 1509947 Overview
In 2014, WHO established the International Scheme to Evaluate Household Water Treatment Technologies. The Scheme aims to consistently and independently evaluate the performance of household water treatment( HWT) technologies against WHO performance recommendations.
This Round I Report of the Scheme is the first ever global assessment of HWT performance, and details the results from a range of HWT technologies including solar, chemical, filtration and ultraviolet( UV). It highlights that of the ten HWT products evaluated, eight were found to meet WHO performance recommendations. The report also recommends specific actions at the national level needed to ensure that health gains from HWT are realized, including strengthening regulation and evaluation of HWT technologies and improving monitoring of use.
SDG 6 – 2018 Synthesis is Report on Water and Sanitation in the 2030 Agenda( planned for May 2018)
In order to adopt an integrated approach to SDG 6 reporting and, thereby, help policy-makers keep track of global progress, the SDG 6 Synthesis Report 2018 on Water and Sanitation( working title) is currently being developed and planned for publication in May 2018.
This report will feed into the discussions of the High-Level Political Forum on Sustainable Development( HLPF) in-depth review of SDG 6 in mid-2018 and enables the United Nations to speak with one voice. The Synthesis report is developed by UN-Water and the production is coordinated by the UN World Water Assessment Programme( WWAP- UNESCO) with the following UN-Water Members woking together in a Task Force: CEO Water Mandate, FAO, ILO, UNECE, UNEP, UNDP, UNICEF, WMO and WHO.
Town Water Supply and Sanitation: Challenges, Solutions, and Guidelines
In Africa, Asia, and Latin America, the number of towns and their populations are expected to double within 15 years, and again within 30. Already, one-third of Africans and Asians live in towns of 2,000 to 200,000 people. This rapid urbanization makes improving water supply
