Utility Network Designer: QGIS plugin and book

Design the water, electricity and gas networks of a district from three layers: its streets, its buildings and its boundary. WHAT YOU GET, IN ONE ZIP FILE • The Utility Network Designer plugin for QGIS, installed from a ZIP. • The book Designing Utility Networks with Graph Theory as a PDF (129 pages). • An installation guide in English and French. WHAT THE PLUGIN DOES • Designs and sizes the three networks along the streets: pipes, cables, transformers, gas regulators and the service connection of every building. • Checks the design rules one by one and reports, with a number, any rule that is not met. • Analyses reliability: valve closures, fire flow, transformer outages, medium-voltage rings and street cuts. • Draws engineering drawings: longitudinal profile, cross-section, junction plan and single-line diagram. • Writes its results as QGIS layers, CSV, JSON, PDF and PNG, with a customer register. WHAT THE BOOK COVERS The method, the proofs and the full application to the commune of Gombe in Kinshasa, Democratic Republic of the Congo. BEFORE YOU BUY • The plugin produces planning studies, not construction drawings. Building anything still requires field surveys, the existing networks and the advice of the operators. • It needs QGIS 3.28 or later and was tested on QGIS 3.44 for Windows. Other installations may need additional Python libraries. • Your data must be in a projected coordinate system in metres. • Large districts take time: on Gombe (13,006 buildings), about 9 minutes for the design and 23 minutes for the analyses. • On Gombe, the plugin passes 77 of 78 rule checks. The failing check is the residual pressure under fire flow. • The gas network of the example is a hypothetical scenario: Kinshasa has no piped gas network. Contact: bisimwamwim@gmail.com
