WATER SUPPLY AND SEWERAGE OF MULTIFUNCTIONAL COMPLEXES

Abstract

The authors of the article revealed the directions of development of water supply and sanitation systems of multifunctional buildings, the specific features and the most rational design solutions of systems. Design of water supply and sanitation components of the complex (residential part, infrastructure) is based on standards and experience in the design of such facilities located separately and operating independently. At the same time, the design has specific features because many objects are parts of a single complex. For example, such as the duplication or redundancy of individual elements of the system; the device of a separate fire extinguishing system, including a reservoir with a supply of water; the use of additional equipment aimed at saving water; installation of local wastewater treatment facilities of industrial premises; design of rain sewers with closed outlets. The article presents a simplified method for determining the maximum hourly and second water and wastewater flow rates for buildings with a large number of water users.Determination on set of rules30.13330.2016 is conducted only for the most water-intensive consumers, which account for more than 90 % of the daily water consumption of the entire complex and the number of which usually does not exceed three.The expenses of other small water consumers are taken into account additionally as a percentage of consumption of water-intensive facilities. It is determined that the share of small consumers in the maximum hourly consumption of water and wastewater is 6 %, in the maximum second consumption - 4,5 %. The collected information is used in the design of a specific object - a complex of two residential buildings on a common stylobate part, which houses the infrastructure facilities of administrative, commercial and fitness purposes.
