A COMPUTER AIDED DESIGN NEW TECHNIQUES FOR SEWERAGE NETWORKS
The aim of this paper is to present a new computer aided design technique for the design of sewers networks or rehabilitation and extensions of existing systems. The software that embodies this new technique is entitled SewerGUI. The paper will also compare different design techniques for sewer network using a case study from Almanshiya area of Khartoum city, Sudan. The design methods investigated and compared are namely; SewerCAD V8 (version 2014), SewerGUI, and manual spread sheet calculation. SewerCAD was upgraded and is currently marketed by Bentley, USA. SewerGUI was developed by the first of this paper. The Microsoft Excel was the spread sheet used in the manual calculations. The collected wastewater is pre-settled in septic tanks and free from large objects, this condition encourages the use of low self-cleaning velocity of 0.4 m/s. The comparison resulted in an estimate of the total cost of the project to be the highest of approximately 15,647,000 SDG when using the design by SewerCAD, the manual calculations yielded an estimated cost of 14,924,000 SDG, and as expected SewerGUI resulted in the minimum cost of 14,097,000 SDG, i.e. over 10% saving with respect to an automated design by SewerCAD.
