In this project we are using solar energy to run this project solar energy is stored in the rechargeable battery. This battery power is uses to switch on the UV lamp along with booster pump. It is a simple water treatment method using solar radiation (UV-A light and temperature) to destroy pathogenic bacteria and viruses present in the water. Its efficiency to kill Protozoa is dependent on the water temperature reached during solar exposure and on the climatic and weather conditions. In addition, the project consists of TDS, Salinity, mineral cattle sensors. TDS = Total Dissolved Solids, is a measure of the dissolved combined content of all inorganic and organic substances present in water. Typically, the higher the TDS value, the more substances dissolved in water. Hence, higher levels of Total Dissolved Solids (TDS) can indicate that water has more contaminants that can pose health risks. The system gives the led indication when the sensor gets Higher levels of TDS. The Salinity Sensor easily and precisely measures the total dissolved salt content in water. Mineral cartridge improves the quality of clean water by adding minerals necessary for proper human development. The filter adds healthy minerals such as Calcium, Magnesium, Sodium, Potassium and others readily found in many natural mineral waters.  

The main blocks of this project are:

• Solar Panel.
• Charging Circuit.
• Rechargeable Battery.
• UV Lamp.
• Dirty tank.
• BOOSTER Pump
• RO
• Salinity
• Mineral Cartridge.
