Water supply – Requirements for systems and components outside buildings – EN 805:2025 pdf

EN 805:2025 is a European standard that provides guidelines and requirements for the management of water supply systems, specifically focusing on the design, construction, and operation of water distribution networks. This standard is crucial for ensuring the safety, reliability, and efficiency of water supply systems across Europe.

The scope of EN 805:2025 encompasses various aspects of water supply management, including the planning and design of water distribution systems, the materials used in construction, and the operational practices necessary to maintain water quality and system integrity. It is applicable to both new installations and the rehabilitation of existing networks, ensuring that all water supply systems meet the necessary regulatory and safety standards.

One of the primary objectives of EN 805:2025 is to ensure that water distribution systems are designed to minimize risks to public health and the environment. This includes guidelines for the prevention of contamination, the management of pressure within the system, and the maintenance of adequate flow rates to meet consumer demand. The standard also emphasizes the importance of regular monitoring and maintenance practices to ensure the long-term sustainability of water supply systems.

Additionally, EN 805:2025 addresses the need for effective communication and coordination among various stakeholders involved in the water supply sector, including municipal authorities, water utilities, and engineering professionals. By establishing a common framework for the design and operation of water distribution networks, the standard aims to facilitate collaboration and improve overall system performance.

In summary, EN 805:2025 serves as a comprehensive guideline for the management of water supply systems in Europe. Its focus on safety, efficiency, and sustainability makes it an essential resource for professionals involved in the planning, design, and operation of water distribution networks. By adhering to the principles outlined in this standard, stakeholders can ensure that water supply systems are capable of meeting the needs of communities while safeguarding public health and the environment.
