Design of sewerage networks using the principles of swot analysis
Abstract
The goals of sustainable development of the territory have a significant impact on modern views on the design and reconstruction of the sewerage network. This approach is characterized by a tendency to consider in the design not only the traditional purely technical aspects of the functioning of the sewerage network. That why, when substantiating the final design solution of the sewerage network, more and more attention is also paid to economic, environmental, legal, social and other aspects. Thus, in order to develop or select a sustainable sewerage network for a given area, a holistic system approach is important. To ensure a multi-criteria assessment of the prospects for the functioning of sewerage networks in a given area (based on the tasks of construction or reconstruction of sewerage networks), this article proposes the application of SWOT analysis not only in the final but also in the initial stages of sewerage network design (for example, to select the tracing scheme of the sewer network). At the same time, due to the universality of the SWOT analysis toolkit, a holistic system approach is provided, which takes into account purely technical and non-technical criteria. Here technical-economic and technical-technological indicators and characteristics which are provided by the current specifications concerning designing of sewer networks are accepted purely technical. Non-technical indicators and characteristics of economic, environmental, legal, social nature are accepted, which are not necessarily included in the current standards for the design of sewerage networks.
Structuring of technical and non-technical criteria in SWOT matrix provides methodically correct application of SWOT analysis principles and allows to increase not only efficiency of design process, but also efficiency of the accepted design decisions of networks of the sewerage of territories. The results of the research were tested in the design of sewerage networks in the recreation area of Shatsk NNP.
