The purpose of this study is to use lines obtained from 3rd degree polynomials to design and fabricate solar powered mobile rainwater collector for collecting rainwater for drinking and cooking. The study consists of two parts; the first part is the design and fabrication of the water collector using lines from 3rd degree polynomials. This was done by generating numbers from 3rd degree polynomials and converting the numbers to lines. The lines were then arranged in such a way as to obtain the 2D image of the water collector. The 2D image was turned to 3D image all using 3D visualizer app. The fabrication of the water collector was then carried out. The second part is the design and fabrication of two tanks of 50 and 100 liters respectfully using the same procedure above. The combination of the rainwater collector and the two tanks produces the mobile rain water harvester. The system can collect rain water directly from the sky and can also be connected to a roof to harvest the rain water. Solar-PV system is incorporated in the design to power a UV-sterilizer for disinfection of the collected water. The mobile rainwater collector is designed to provide safe, clean and natural water for the purpose of drinking and cooking. The microbial tests conducted using membrane filtration method of the raw rainwater sample collected from the system indicated that there were 0 E.coli and 5 total coliforms these were all neutralized after passing the water through the UV sterilizer.
