Water Safety Plan

Introduction: The water safety plan is a systematic approach that aims to ensure the quality of water distributed to consumers. In 2004, the World Health Organization issued a statement implementing the water safety plan. The plan is underway in Iran. The purpose of this study is to review the studies conducted from 2004 to 2020. Materials and Methods: Present article is a systematic review study to search for keywords in a combination of "water safety plan" (WSP), "Iran", "Hazard Analysis and Critical Control Points", (HACCP) and "water" in international databases including: PubMed, Science Direct, Google Scholar, as well as national databases include: Magiran and SID. Results: In the initial search, 671 articles were found that after screening based on the Prisma checklist, 15 articles were included in the study for further review. The results showed that in the implementation of WSP, the highest score is related to Qom city with 68.64% and the lowest value is related to Khoy city with 17.5%. Improvement and upgrade program, support program development, and review of WSP courses have received less attention. Low staff familiarity with WSP, insufficient team composition and lack of coordination between them in holding regular meetings can be the reason for poor implementation of WSP in Iran. Conclusion: The full implementation of the water safety plan controls the risks in the water supply system and reduces costs, as well as improves and increases the quality of water distributed to consumers.

Background: The quality of water for human consumption is an objective of fundamental importance for the defense of public health. Since the management of networks involves many problems of control and efficiency of distribution, the Water Safety Plan (WSP) was introduced to address these growing problems. Methods: WSP was applied to three companies in which the water resource assumes central importance: five water kiosks, a third-range vegetable processing company, and a residence and care institution. In drafting the plan, the terms and procedures designed and tested for the management of urban distribution systems were applied to safeguard the resource over time. Results: The case studies demonstrated the reliability of the application of the model even to small drinking-water systems, even though it involved a greater effort in analyzing the incoming water, the local intended use, and the possibilities for managing the containment of the dangers to which it is exposed. This approach demonstrates concrete effectiveness in identifying and mitigating the dangers of altering the quality of water. Conclusions: Thanks to the WSP applied to small drinking-water systems, we can move from management that is focused mainly on verifying the conformity of the finished product to the creation of a global risk assessment and management system that covers the entire water supply chain.

Background: Water safety plan is a systematic approach to ensure the quality of water delivered to consumers from catchment to consumption. Methods: This study was conducted on the groundwater system of Talesh, Gilan, in 2020-2021. A Water Safety Plan (WSP) consists of 5 phases and 12 steps. In the implementation of this plan, all modules were reviewed. Software checklists were prepared and based on the background information in Talesh Water and Wastewater Company, interviews with experts and field visits were performed, and then, entered into WSP QA TOOL software. Results: Out of 440 raw scores, 222 points were obtained, indicating 50.45% compliance with WSP. The description system with the highest score (100%) and the management procedures with the lowest score (50%) were in line with this plan. The stages of development and supporting program and review of WSP cannot be evaluated due to the incomplete implementation of water safety plan in Talesh. Between different parts of the water supply system, more attention has been paid to production sources and points of use. Conclusion: This study identifies the inefficiency in dependence on the final tests and the necessary items in updating the supply system of Talesh. According to the study of the different stages of WSP, the system has a moderate level of safety.

The Water Safety Plan (WSP) is considered the preferred approach to ensure drinking water safety by the World Health Organization (WHO). This approach ideally requires extensive scientific and technical input from a multidisciplinary team of experts. However, in small- and medium-sized municipalities in Austria, financial and personnel resources are usually of very limited availability. Therefore, a spreadsheet based WSP tool was designed to facilitate the implementation of the WSP approach at these small supply units. The WSP tool comprises the relevant national Austrian guidelines, which include the key components of the WSP by the WHO. The tool provides an overview of the required steps, explains how to carry out each step and guides the user through the three key components: system and hazards assessment, control measures and operational monitoring, and management. The practical application of the WSP tool was tested at 12 water utilities over a period of three months. After this period, the tool was improved based on collected feedback from the water utilities.

The good installation, as well as commissioning plan, of a water network is a crucial step in reducing the risk of waterborne diseases. The aim of this study was to monitor the microbiological quality of water from a newly built pavilion before it commenced operation. Overall, 91 water samples were tested for coliforms, Escherichia coli, enterococci, Pseudomonas aeruginosa and Legionella at three different times: T0 (without any water treatment), T1 (after treatment with hydrogen peroxide and silver ions at initial concentration of 20 mg/L and after flushing of water for 20 min/day for seven successive days) and T2 (15 days later). Coliforms were detected in 47.3% of samples at T0, 36.3% at T1 and 4.4% at T2. E. coli was isolated in 4.4% of the samples only at T1, while enterococci appeared in 12.1% of the samples at T1 and in 2.2% at T2. P. aeruginosa was isolated in 50.5% of the samples at T0, 29.7% at T1 and 1.1% at T2. Legionella pneumophila serogroup 8 was isolated in 80.2% of the samples at T0, 36.3% at T1 and 2.2% at T2. Our results confirmed the need for a water safety plan in new hospital pavilions to prevent the risk of waterborne diseases.

Water Safety Plan

Considerable effort has been made worldwide to disseminate information and provide technical assistance to encourage the adoption and implementation of the water safety plan (WSP) methodology. Described since the third edition of the World Health Organization (WHO) Guidelines for Drinking-water Quality, a WSP provides guidance for water utilities to ensure the delivery of safe drinking water and protect health. Attention is now being given to understand the success of efforts to advance adoption of the WSP methodology in the Latin America and Caribbean (LAC) region. More specifically, there is interest in knowing how early adopters developed strategies to implement the WSP methodology and what challenges exist for further implementation. To better understand adoption and implementation trends, key informants from five LAC countries were interviewed and case studies were developed to reveal the diversity of WSP approaches applied in the region. Results indicate that WSP implementation is more widespread than previously reported. Respondents affirmed that the WHO Guidelines for Drinking-water Quality are routinely used as a model for country-level drinking-water regulations, which has led to uptake of the WSP methodology. Interview respondents also revealed innovative national strategic approaches for WSP implementation.

The purpose of this study is to report the experience of the implementation and application of a 3-year Water Safety Plan (WSP) together with the secondary disinfection of water by monochloramine to control and prevent healthcare-associated legionellosis in an Italian hospital strongly colonized by Legionella. Risk assessment was carried out by the WSP team. The main critical control points focused on in developing the WSP for the control of Legionella was the water distribution system. A sampling plan for the detection of Legionella was implemented. A widespread contamination of the hot water distribution system by L. pneumophila sg5 was found. Results after 3 years of the continuous disinfection of hot water with monochloramine indicate the eradication of Legionella. The implementation and application of a WSP in a hospital, together with the disinfection of the water distribution system with monochloramine, can be effective in controlling the growth of Legionella and in preventing nosocomial legionellosis.
