| Summary: | In this research, to facilitate the construction of lines at shallower depths, we examine the solution of reducing the slope of the lines located east of Ahvaz city. Also, we will compare the economy between these situations. . this research explores alternative slopes. The main lines in the east of Ahvaz city were designed with slopes of 1/2d, 1/3d, and less than 1/3d using trial and error with SewerCAD software. . The reduction of operational costs, it leads to a reduction in the cost of pumping station equipment and station operation costs and a reduction in the cost of line repairs and maintenance. With a standard 1/2d slope, the average reduction depth of the lines is 1 meter, 9.7% increase in pipe purchase cost, 10% reduction in implementation cost, 9.5% reduction in Pump stations equipment cost, 9.6% reduction in maintenance; in the 1/3d design, the depths reduction is 1.2 meters, 15% increase in pipe purchase cost, 12% reduction in implementation cost, 12% reduction in station equipment cost, 10.4% reduction in repair and maintenance cost; in the trial and error design, the working depth is reduced to 1.35 meters 18.9% An increase in the cost of buying pipes leads to a 15% reduction in the cost of implementation, a 12% reduction in the cost of station equipment, and an 11.7% reduction in the cost of repairs and maintenance.. Based on a comprehensive examination of all parameters, a design with a standard slope of 1/(2d) is recommended. |
