Water Supply System Design

Abstract

potable water distribution systems are broken into major and minor distribution networks. Major water distribution networks refer to large-scale municipal pipe systems extending from the treatment plant to the upstream node of the water service line for buildings. Minor water distribution systems, referred to as plumbing water distribution systems, run from the upstream node of the water service line to all interior plumbing fixtures and demand nodes associated with the building. Most texts and research papers focus on major systems, while only a small number of documents are available concerning the design and analysis of minor systems. In general, the available minor system documents are quite prescriptive in nature. This paper presents a comprehensive evaluation of contemporary plumbing water distribution system, Drainage and rain Water systems. All underlying theory is explained and advantages and drawbacks are discussed. Issues have been raised regarding the accuracy of water demand estimation procedures for water supply systems,. Demand estimates are crucial for designing underground water supply systems.
