A computer programme was developed using Fortran utilizing IBM-PC compatible microcomputers to design the primary sedimentation or clarification in a municipal wastewater treatment plant. The programme is used to determine the dimension and capacity of two rectangular primary sedimentation basins. The detention time 'and the overflow rate at an average design flow was investigated for the basins' designed dimensions. It also determined the dimension of the influent and emuent structure including the hydraulic flow profile in the basin. The weir loading at average design flow was also investigated. The sludge and scum quantities including the effluent quantities was also calculated. The programme was written in a subroutine called from the main programme which also call other subroutines for designing other facilities in the treatment plant. The programme runs successfully given the input data which is the average design flow calculated which based on the number of population served. The results are easy to interpret and automatically appear either on the computer screen or in an output file.
