1. Introduction
The availability of clean, safe water is a basic human right. Maintaining the standard of water delivery systems is crucial to public health and more so if they pertain to the pharmaceutical industry. Our study addresses the development and implementation of a comprehensive framework for water system standardization, specifically designed to comply with the World Health Organization’s (WHO) guidelines [
1], in light of the global water quality crisis and the urgent need for standardized water quality management. This paper explores the technique of our approach to create a robust system to ensure that the system is designed in such a way that standards are met. Specifically, we integrate a Process and Instrumentation Diagram (P&ID) [
2] with an Excel tool that has been meticulously designed.
Like many underdeveloped countries, Pakistan has enormous obstacles in terms of providing its people with access to clean water. Water supply systems vary greatly in quality, and waterborne infections are common [
3]. We realized that in order to address these issues, a methodical strategy to evaluate and raise water system standards was required. The urgency of addressing concerns related to water quality, improving public health outcomes, and harmonizing with worldwide standards promoted by the World Health Organization spurred the development of our framework.
Our methodology is based on the combination of an Excel-based application and a thorough P&ID. The P&ID provides a thorough visual depiction of the water purification process, including the design and all of the equipment currently in use. A comprehensive insight into the system is made possible by this graphical representation, which also helps to identify possible areas for development. The P&ID also includes water standards for each step, which provide a convenient reference for evaluating the output quality of water.
Our Excel application transforms WHO annexure standards into a useful scoring system to support the P&ID. Every item in the annexure relates to a certain aspect of the functioning of the water system, and these factors are systematically assessed in comparison to the procedures and infrastructure of our company. The end product is a thorough evaluation that identifies any departures from WHO guidelines as well as areas of conformity.
By ensuring that water systems continuously fulfill international standards, a standardized approach lowers the risk of waterborne illnesses and improves public health in general. In addition, it promotes sustainable growth, eases regulatory compliance, and builds trust in the quality of the water supply.
In summary, this study hopes to formulate a framework which can be used on an industrial scale for the standardization (as per any regulatory body) of various systems installed.
RQ1: How to design a robust ‘systems’ implementation tool on an industrial scale.

3. Methodology
3.1. Designing Process and Instrumentation Diagram (P&ID)
The first step involved in our research was the creation of a comprehensive Process and Instrumentation Diagram (P&ID) for the entire water system layout of the industry under study as depicted in
Figure 1. This diagram provides a visual representation of the various components, connections, and flow paths within the system. To accomplish this, we meticulously analyzed the existing infrastructure, including pipelines, pumps, valves, tanks, and other relevant equipment. Through collaboration with industry experts and referencing technical documentation, we accurately depicted the layout and interconnections of these elements. The P&ID served as a foundational blueprint for understanding the operational dynamics and flow of materials within the water management system.
3.2. Assessment of Working Conditions and Parameters
Following the creation of the P&ID, our research focused on assessing the working conditions, parameters, and operations of each equipment component installed within the water system, in adherence to Standard Operating Procedures (SOPs). Through a combination of on-site inspections, data collection, and interviews with maintenance personnel and operators, we gathered detailed information regarding the functionality and performance of individual equipment units. Key parameters such as pressure, temperature, flow rates, and quality metrics were systematically analyzed. Any deviations from expected working conditions or operational parameters were meticulously documented.
3.3. Compilation of Comprehensive Documentation
The culmination of our research efforts involved compiling all the acquired data, observations, and analyses into a single comprehensive document. This document now serves as an invaluable resource containing detailed information on the industry’s water management system. Drawing upon the insights gained from the P&ID design and equipment assessments, we organized the information in a structured format for easy reference and accessibility.
Each section of the document provides a thorough overview of specific aspects of the water system, including equipment specifications, operating procedures, maintenance protocols, troubleshooting guides, and safety considerations.
3.4. Consultation of Guidelines
We accessed the latest WHO guidelines on ‘Water for Pharmaceutical Use’ (annexure) to establish a benchmark for evaluating the water management system against industry standards. Each chapter of the guidelines was carefully reviewed, and the paragraphs were broken down into individual points for clarity and ease of reference. These points were then organized into corresponding categories within an Excel tool, facilitating the systematic assessment and identification of gaps in compliance. An extract is attached in
Figure 2.
3.5. Development of Evaluation Tool
An Excel-based evaluation tool was developed to streamline the assessment process and facilitate efficient gap analysis. The tool consists of separate tabs for each chapter of the guidelines, with points listed under each category. Stakeholders can input relevant data and observations against each point, adhering to regulatory requirements.
3.6. Technical Support Identification
A dedicated section within the evaluation tool allows stakeholders to identify the technical expertise required to address identified gaps and achieve compliance with WHO guidelines. This ensures that necessary resources and expertise are identified upfront, streamlining the implementation of corrective measures.
3.7. Projection of Improvement
Another feature of the evaluation tool is the ability to project the timeline for improving the current compliance score. Managers can input anticipated timelines for addressing identified gaps and achieving desired levels of compliance, facilitating strategic planning and resource allocation.
3.8. Assessment of Capital Expenditure
The evaluation tool includes functionality to assess whether capital expenditure will be required to address identified gaps. Boards can indicate whether investments in equipment, infrastructure, or other resources are necessary to achieve compliance, aiding in budgetary planning and decision-making.
3.9. Integration of Stakeholder Comments
Lastly, the evaluation tool allows for the addition of comments against each point, providing valuable insights, observations, and recommendations. This promotes collaboration and ensures that diverse perspectives are considered in the gap analysis and compliance improvement process. This methodology, coupled with the development of a comprehensive evaluation tool, enables a structured and systematic approach to assessing regulatory compliance and facilitating efficient operations as per WHO guidelines for water used in pharmaceutical processes.
3.10. Development of Graphical Spiderweb Layout
In addition to the Excel-based evaluation tool, a graphical spiderweb layout was developed to visually represent the scores of each point against the WHO guidelines. The spiderweb layout provides a clear and intuitive visualization of the compliance status, both individually for each point and collectively for each chapter. Each point is represented by a node on the spiderweb graph, with lines connecting the nodes to form a web-like structure. The length of each line corresponds to the score of the respective point, allowing stakeholders to quickly identify areas of strength and weakness within the water management system. By examining the graph for each chapter, involved parties can ascertain which specific points require improvement and which departments or stakeholders are responsible for addressing them.
3.11. Utilization of a Gantt Chart for Compliance Projection
In addition to the spiderweb layout (
Figure 3a), a Gantt chart was employed (
Figure 3b) to visually depict the timeline for achieving 100% compliance with the WHO guidelines, with milestones and tasks organized chronologically. The Gantt chart serves as a dynamic planning tool, enabling stakeholders to adjust timelines and priorities as needed to optimize the compliance improvement process.
This consolidated document not only serves as a repository of knowledge for internal stakeholders but also functions as a practical reference guide that can be consulted whenever there is a need to identify, understand, or address issues related to the water management system.
