Good sanitary sewer design practice requires evaluation of alternative locations, slopes and pipe sizes. However, cost considerations generally keep alternative evaluations to a minimum. Use of the Sanitary Sewer Design Program gives the designer the opportunity to rapidly evaluate alternatives and choose the solution best suited to the clients' needs. Use of the program requires the designer to have a suitable topographic map with surveyed sewer line locations. The program is very interactive with the designer, requesting ground elevation, quantity of flow, and station value. The program gives the designer the option to design by minimum slope, fixed slope or invert, and drop manhole. Computer use allows the designer to perform error free calculations and to focus attention on the actual design work.
