Technologies for Climate Change Adaptation
This guidebook, released by UNEP Risoe Center, describes adaptation strategies in the categories of water conservation; storm water control and capture; resilience to water quality degradation; preparation for extreme weather events; diversification of water supply; and mitigation. It has been made widely available and will help both developed and developing countries understand means of increasing resilience to the uncertain effects of future climate change. The Water Institute at UNC provided technical and methodological expertise.

Comprehensive Framework for integrated risk management in WSP
Risk assessment and risk prioritisation are critical elements of a Water Safety Plan. However the process can be complex, require considerable resources and take a long time. Therefore before establishing a risk management system it is important to be clear on the most cost effective approach to meet local priorities and needs. This document provides an overview of the TECHNEAU Generic Framework, which is a comprehensive structure for integrated risk management from catchment to consumer in Water Safety Plans, considering both water quality and water quantity
WSP training package

Chemical safety of drinking-water: Assessing priorities for risk management
This text provides guidance on the chemical safety of drinking-water. Chemical contaminants of drinking-water are often considered a lower priority than microbial contaminants, because adverse health effects from chemical contaminants are generally associated with long-term exposures, whereas the effects from microbial contaminants are usually immediate. Nonetheless, chemicals in water supplies can cause very serious problems. The objective of this text is to help users at national or local level to establish which chemicals in a particular setting should be given priority in developing strategies for risk management and monitoring of chemicals in drinking-water. The document will be useful to public health authorities, those responsible for setting standards and for surveillance of drinking-water quality, and to water supply agencies responsible for water quality management. In particular, this publication will be applicable in settings where information on actual drinking-water quality is limited, which is the case in many developing countries and in rural areas of some developed countries.

Water safety plan template including climate considerations for rural water supplies: United Rep. of Tanzania
This water safety plan (WSP) template was developed to support the integration of climate risks into the WSP approach in rural areas of the United Rep. of Tanzania. Examples are presented on how to complete the template, and the information should be considered and customized to the local context.
This template is based on WHO EURO (2014) Water safety plan: a field guide to improving drinking-water safety in small communities, but adapted to the local context.
This resource was developed as part of the Department for International Development (DFID, UK)-funded project on “Building adaptation to climate change in health in least developed countries through resilient WASH” which was implemented from 2013-2018 in Bangladesh, Ethiopia, Nepal and Tanzania.

Legionella spp. Risk Assessment in Recreational and Garden Areas of Hotels
Several Travel-associated Legionnaires’ disease (TALD) cases occur annually in Europe. Except from the most obvious sites (cooling towers and hot water systems), infections can also be associated with recreational, water feature, and garden areas of hotels. This argument is of great interest to better comprehend the colonization and to calculate the risk to human health of these sites. From July 2000–November 2017, the public health authorities of the Island of Crete (Greece) inspected 119 hotels associated with TALD, as reported through the European Legionnaires’ Disease Surveillance Network. Five hundred and eighteen samples were collected from decorative fountain ponds, showers near pools and spas, swimming pools, spa pools, garden sprinklers, drip irrigation systems (reclaimed water) and soil. Of those, 67 (12.93%), originating from 43 (35.83%) hotels, tested positive for Legionella (Legionella pneumophila serogroups 1, 2, 3, 6, 7, 8, 13, 14, 15 and non-pneumophila species (L. anisa, L. erythra, L. taurinensis, L. birminghamensis, L. rubrilucens). A Relative Risk (R.R.) > 1 (p < 0.0001) was calculated for chlorine concentrations of less than 0.2 mg/L (R.R.: 54.78), star classification (<4) (R.R.: 4.75) and absence of Water Safety Plan implementation (R.R.: 3.96). High risk (≥104 CFU/L) was estimated for pool showers (16.42%), garden sprinklers (7.46%) and pool water (5.97%).
Documentary on WSP implementation
Beautiful short film on how to achieve safe drinking-water by Björn Weber, Oliver Meinborn and Grimme-price winner Ute Hilgeford. Launched by the World Health Organization on World Water Day 2019.
