Public Health Water System Design

摘要

The Health & Safety Executive also publishes guidance and codes of practice relating to domestic water services, which have special legal status. These standards and regulations set down detailed national requirements for the design, installation, operation and maintenance of plumbing systems, water fittings and water-using appliances. They are designed to prevent misuse, waste, undue consumption or erroneous measurement of water, and to prevent drinking water contamination. However, no two water-system design engineering projects are ever the same. Often subtle differences between two similar projects can bring significant issues and outcomes in terms of plant and pipe sizing, and the resulting system's performance. Best practice advice when evaluating efficient measures for inclusion in water supply systems would therefore be to maintain focus on the health and wellbeing of end-users, and do not let efficiency lead to compromises in system performance or contamination of the water system.
