A comparative study between conventional and solids-free sewerage systems

Abstract

The aim of this study was to examine the possibility of more suitable and economic alternatives to existing conventional sewerage reticulation systems where such systems might be required. Existing solids-free systems in various towns and townships have accordingly been investigated to determine the design parameters, effectiveness and economy of these systems and to apply the findings to designs for more practicable and purposeful systems. Cost estimates have been carried out for several alternative designs for conventional and solids-free systems. It was found that solids-free systems could be more economical, depending on the terrain and the utilization of existing infrastructure such as septic tanks.
