Water Distribution System in a Hemodialysis Center Water systems are an integral part of the dialysis facility. They are vital to the safe and effec-tive treatment of the patient. There are a variety of components used to supply water to each dialysis machine. Part of this system of components is the piping used to distribute this water.

2.02 SYSTEM ANALYSIS The proposed water system shall be analyzed for the following three conditions:1. Peak hour demands with wells/booster pumping plants on. For the peak hour demand flow analysis, the pressure at each node shall be a minimum of 40 psi and a maximum of 120 psi. 2. STANDARD TECHNICAL SPECIFICATIONS FOR WATER & In addition, lists of approved materials for water distribution and wastewater collection systems are included in this document. Unless otherwise specified in the project plans and/or specifications, these materials can be considered by the Contractor contingent upon approval by the Owner. PREFACE P - 1 WATER DISTRIBUTION STANDARD SPECIFICATIONSSep 05, 2017 · to the Citys water distribution system. These include, but are not limited to:1. Payment of fees prior to issuance of Building Permits. 2. Lots requiring pressure regulating valves or booster pumps. 3. Backflow protection. 4. Public water access requirements, such as gates or access roads.
standard size shall be used. Water mains shall be sized so that the pressure at maximum flow conditions is at least twenty-five (25) psig in all parts of the distribution system. In addition, the velocity at maximum flow must be no more than ten (10) fps. Friction losses shall be calculated by the WATER DISTRIBUTION SYSTEM ENGINEERING DESIGN Water Distribution System Rochester Water Bureau Engineering Design Guidelines 1-3 June 2010 Design & Construction Standard Specifications Pipelines Occupancies (available on the web).
