Abstract
The study is a continual quest towards the provision of affordable, health-friendly fresh potable water in rural areas; using available, affordable and durable materials for the construction of a solar distiller for freshwater production. The aim of this study was to develop a solar distiller for the production of potable water in waterborne diseases infested rural communities in northern Nigeria. Solar radiation with an intensity of 32 kcal/day was made to pass through a transparent polythene of 1039.6 cm2 that covers a 6800 cm3 of water collected through evaporator made with 78% refined clay constituent distilling 1.3 litres/day of pure water. An efficiency of 77% was determined after several test runs. Information from this study will serve as a guide to researchers on the production of portable water from the solar distiller. Also, it will guide the government and agencies on policy and decision making on water resources.

The principle of operation and maintenance of distillation was employed in the developed solar distiller, it is very important to note that the effective operation of the system depends on the amount of vapour that can be condensed in the still, and maximum vapour condensation will only be achieved if there exists little or no vapour escape from the system
Summary
The study is a continual quest towards the provision of affordable, health-friendly fresh potable water in rural areas; using available, affordable and durable materials for the construction of a solar distiller for freshwater production. Literature has revealed numerous designs and ideas related to the solar-powered distiller, such as The Solar Collection System Design with radiation concentrated on heat absorber vanes (Husson, 1987) This design contained a few key ideas such as the use of Fresnel lenses to increase the efficiency and overall production of the distiller by focusing the incoming radiation onto a trough of water. The phase changes from water to water vapor can be completed and maintained at a constant rate This design tends to increases the overall water output of the system, the construction of heat exchangers, complicated plumbing, and electrical power generation lead to a device that is too expensive and impractical to be utilized in the areas that would require such a device (David, 1991). The spare parts for maintenance and repair are scare and difficult to get as their parts comes from abroad, their production countries
