Abstract

Adequate supply of clean water is even more significant for a
primary school as it ensures hydration, sanitation, hygiene leading to a general
wellbeing of the pupils. This research work successful designed a solar
powered water supply system for Kagadi Model Primary School (KMPS) and
its environs. The research design takes into account the population of 1725
students with total daily water demand of 31.05𝑚3/day and mean solar
radiation of 5.1kwh which corresponds to an elevation /slope of 1degree. The
flow rate of 6.2105𝑚3/day/hour was obtained using 5.1kwh irradiance. The
developed system will help to distribute water fairly to the KMPS and its
environ at very a cheap and steady manner for the pump will be powered with
solar energy of 200Wp. The solar water pump of 211.407W was energized
using solar energy system to pump water into the storage facility (reservoir)
before distributing it by the help of gravitational force to various locations for
consumption. The cost of running this designed solar powered pump for the
period of 20years will generate a net income of 2.28billion Ugandan shilling
compared to conventional way they are running it as of 2023. This solar
powered water system when implemented will curb the problem of water
scarcity, provide clean water and reduce unhygienic nature of the
environment, boast Uganda economy as it in line with Sustainable
Development Goals (SDGs). This study recommends the implementation of this design to provide, cheap, clean and steady water supply for the residents of the study area.
