The idea of harmonizing inclined flat plates along with a tread-type solar still is breached to maximize the productivity of the solar still. In this tread-type solar still, an absorber plate on the top beneath a customary basin of area 1 m2 was placed. It is composed of subsequent trays inclined flat plate collectors which provide additional exposure area. This demonstration is channeled with various water depths in the customary basin. A solar still was constructed and operated with an experimental setup to estimate the degree of similarity. The main objective is to reinforce the evaporation rate; wicks cotton, coconut coir and sponge pin are placed on the tilted plate, which provide capillary action. The output was maximum for pins inserted in sponges. The efficiency of stepped still produces 17%, and nearly 3% increase in the efficiency when compared to conventional still. The demonstrated value is unanimous with the analysis concern with knowledge, using RSM software for developing the numerical modeling as a water output for various packing materials in different water depth condition; the productivity as well as efficiency was also compared. Experimental analysis was performed, and it was found to be significant with that of RSM ANOVA calculation.
