Water Supply Systems in Multi-Apartment Buildings and their Design Characteristics

Abstract

The research considers ongoing changes in the current system of legal regulation in the field of water supply and wastewater disposal of multi-apartment buildings (MABs). The authors present results of operational and design standards of water consumption analysis. It is shown that the existing regulatory and technical documents need adjustment in terms of determining the maximum possible consumption of cold and hot water for MABs residential units. The paper also puts forward an algorithm of hydraulic calculation of MABs domestic water supply systems according to the methodology developed in the Academy of Construction and Architecture in Samara State Technical University (ACA SamSTU).

Influence of Design Efficiency of Water Supply Network Inside Building on its Optimum Usage: Review

“…The internal water supply network pipe sizes and storage tanks mainly depend on the water demand of the users inside the building. It is determined by several factors including users' habits, climate, geographical location, water bill cost, and other factors (Zotov et al, 2022). So that the effective design of the inside water supply network can be achieved and avoiding the oversizing and under sizing problems by determining the optimal usage of the water demand by users ( Tiago and Orestes, 2020).…”

Simulation Design and Analysis for Water Network Inside Building Using Elite(S-Pipe) Software

“…The design importance of water supply networks inside buildings has emerged to provide the daily demand for water for drinking, cooking, showering, and various activities, the design is depends mainly on calculating the demand of water consumed and the appropriate pressure for operation [3], the process of calculating the water demand for the design of water supply networks inside buildings is 1222 (2023) 012006 IOP Publishing doi:10.1088/1755-1315/1222/1/012006 2 depending on the Hunter curve method [4], which depends in its calculations on giving each fixture in the network a numerical value that depends on the fixture's consumption of water simultaneously, this value is called the Fixture Unit and by using Hunter curve to find the water demand of building [5]. The appropriate design pressure value for the water supply network inside the building to exceed the height difference between the water source in the network and the highest fixture in the network, the network operating pressure value represents the pipes friction losses in the network, and the pressure required to operate the fixtures, [6], depending on the procedures in the global or local codes like (The American Society of Plumbing Engineers (ASPE), Uniform Plumbing Code, National Standard Plumbing Code, International Building Code (IBC), International Plumbing Code (IPC)) and using the values extracted from the water demand calculations and the design pressure to operate the water supply network inside the building, the sizes of the parts of the network are calculated such as tanks, pipes, fitting and also the pumps discharge and head [7].…”
