Measuring the Impacts of Water Safety Plans in the Asia-Pacific Region
This study investigated the effectiveness of Water Safety Plans (WSP) implemented in 99 water supply systems across 12 countries in the Asia-Pacific region. An impact assessment methodology including 36 indicators was developed based on a conceptual framework proposed by the Center for Disease Control (CDC) and before/after data were collected between November 2014 and June 2016. WSPs were associated with infrastructure improvements at the vast majority (82) of participating sites and to increased financial support at 37 sites. In addition, significant changes were observed in operations and management practices, number of water safety-related meetings, unaccounted-for water, water quality testing activities, and monitoring of consumer satisfaction. However, the study also revealed challenges in the implementation of WSPs, including financial constraints and insufficient capacity. Finally, this study provided an opportunity to test the impact assessment methodology itself, and a series of recommendations are made to improve the approach (indicators, study design, data collection methods) for evaluating WSPs.
Time series study of weather, water quality, and acute gastroenteritis at Water Safety Plan implementation sites in France and Spain
Water Safety Plans (WSPs), recommended by the World Health Organization since 2004, can help drinking water suppliers to proactively identify potential risks and implement preventive barriers that improve safety. Few studies have investigated long-term impacts of WSPs, such as changes in drinking water quality or public health; however, some evidence from high-income countries associates WSP implementation with a reduction in diarrheal
disease. To validate the previously observed linkages between WSPs and health outcomes, this time series
study examined site-specific relationships between water-related exposures and acute gastroenteritis rates at three locations in France and Spain, including the role of WSP status. Relationships between control or exposure variables and health outcomes were tested using Poisson regression within generalized additive models. Controls included suspected temporal trends in disease reporting. Exposures included temperature, precipitation, raw water quality, and finished water quality (e.g., turbidity, free chlorine). In France, daily acute gastroenteritis cases were tracked using prescription reimbursements; Spanish data aggregated monthly acute gastroenteritis hospital visits. The models identified several significant relationships between indicators of exposure and acute gastroenteritis. Lag times of 6–9 days (including transit time) were most relevant for hydrological indicators (related to precipitation, runoff, and flow) at the two French sites, indicative of viral pathogens. Flush events (defined as surface runoff after a two-week antecedent dry period) linked to nonpoint source pollution were associated with a 10% increase in acute gastroenteritis rates at one location supplied by surface water. Acute gastroenteritis rates were positively associated with elevated turbidity average or maximum values in finished water at locations supplied by both surface and groundwater, by about 4% per 1-NTU increase in the two-week moving average of daily maxima or about 10% per 0.1 NTU increase in the prior month’s average value. In some
cases, risk appeared to be mitigated by WSP-related treatment interventions. Our results suggest drinking water exposure is associated with some potentially preventable gastrointestinal illness risk in high-income regions.

Experiential Learning through Role-Playing: Enhancing Stakeholder Collaboration in Water Safety Plans
Improved water safety management, as addressed by the Sustainable Development Goals, can be aided by Water Safety Planning, a risk-assessment and risk-management approach introduced
by the World Health Organization and implemented to date in 93 countries around the globe. Yet, this approach still encounters some challenges in practice, including that of securing collaboration among the broad range of stakeholders involved. This paper presents a role-playing game designed to foster stakeholder collaboration in Water Safety Plans (WSP). In this role-play, participants take on different stakeholders’ roles during a collective (team-based) decision-making process to improve water supply safety in a fictive town. The game is the result of a transdisciplinary initiative aimed at integrating knowledge across technical and governance aspects of WSPs into an active learning experience for water sector actors from diverse backgrounds. It exposes participants to the four phases of Kolb’s experiential learning cycle: concrete experience, reflective observation, conceptualization and active experimentation. This paper discusses potential impacts of the WSP role-play, including skills and knowledge development among participants, which can support cross-sectoral integration and dealing with complexity in decision-making. These are capacity assets strongly needed to address water safety management challenges in a sustainable way.

Guidelines for Drinking Water Safety Plans for Buildings in Hong Kong
Based on the recommendations of the World Health Organization (WHO), the Water Supplies Department (WSD) of Hong Kong has recently developed guidelines and templates for Water Safety Plan (WSP) for Buildings. The guidelines and templates aim at assisting building owners or management agents to develop their own WSPs to enhance water safety in buildings by using a risk-based and multiple barrier approach. Implementation of WSP for buildings requires concerted efforts of building management and plumbing practitioners, including identifying and assessing potential risks of the inside service, deriving control measures and carrying out the corresponding checking and maintenance. In addition, the WSP will be verified and updated by the building management through periodic auditing and review. The guidelines and templates for general buildings and schools have been launched in September 2017 for voluntary adoption by building owners or management agents.

Application of potable reuse is also illustrated through a number of case studies.
The guidance is intended for use by drinking-water suppliers and regulators who are familiar with the WHO’s Guidelines for drinking-water quality and, in particular, the framework for safe drinking-water, including water safety plans. This publication may also be useful to others with an interest in potable reuse including environmental health and water resource professionals.
A role-playing game for practising stakeholder collaboration in Water Safety Plans
One of the challenges in the implementation of Water Safety Plans (WSPs) is stakeholder engagement. For this reason, IHE Delft Institute for Water Education has developed a role-playing game for practising stakeholder collaboration in WSP. The game can be used in WSP training or during educational activities for water safety and WSP at graduate and post-graduate level. Its goal is for participants to experience the importance of stakeholder engagement in WSPs, and particularly in the decision-making process when investing in the rehabilitation and maintenance of a drinking water supply system from catchment to consumers. Participants will experience how this process can be influenced by information exchange between stakeholders and how this will eventually lead to greater awareness when assembling the WSP team.

Water quality, compliance, and health outcomes among utilities implementing Water Safety Plans in France and Spain
Water Safety Plans (WSPs), recommended by the World Health Organization since 2004, seek to proactively identify potential risks to drinking water supplies and implement preventive barriers that improve safety. To evaluate the outcomes of WSP application in large drinking water systems in France and Spain, we undertook analysis of water quality and compliance indicators between 2003 and 2015, in conjunction with an observational retrospective cohort study of acute gastroenteritis incidence, before and after WSPs were implemented at five locations. Measured water quality indicators included bacteria (E. coli, fecal streptococci, total coliform, heterotrophic plate count), disinfectants (residual free and total chlorine), disinfection by-products (trihalomethanes, bromate), aluminum, pH, turbidity, and total organic carbon, comprising about 240K manual samples and 1.2M automated sensor readings. We used multiple, Poisson, or Tobit regression models to evaluate water quality before and after the WSP intervention. The compliance assessment analyzed exceedances of regulated, recommended, or operational water quality thresholds using chi-squared or Fisher’s exact tests. Poisson regression was used to examine acute gastroenteritis incidence rates in WSP-affected drinking water service areas relative to a comparison area. Implementation of a WSP generally resulted in unchanged or improved water quality, while compliance improved at most locations. Evidence for reduced acute gastroenteritis incidence following WSP implementation was found at only one of the three locations examined. Outcomes of WSPs should be expected to vary across large water utilities in developed nations, as the intervention itself is adapted to the needs of each location. The approach may translate to diverse water quality, compliance, and health outcomes.

Microbial barrier analysis (MBA) – a guideline
In order to safeguard the public against waterborne diseases, water utilities must secure that multiple, microbial barriers are provided for in their drinking water systems. In most water utilities disinfection of the water represents an important barrier, but microbial barriers may also be achieved by other actions, for example in the catchment area.
Based on experiences from Norway, Sweden and Finland, this guideline is a helpful tool for implementing Water Safety Plans. The guideline explains the "barrier concept" and assist water utilities as well as their their consultants in determining what actions to take to ensure that the microbial barriers in their systems are sufficient – and that the water is safe to drink.
