the diagram below shows a simple system that turns dirty water into clean water.
The diagram shows a method for filtering dirty water using a barrel and a drum, a pipe and two taps.
First, the drum and barrel are placed next to each other so that the top of the barrel is higher than the drum. These items are linked by a pipe that runs from bottom of the barrel into the side of the drum. Next, the filter is made by adding sand, charcoal and gravel to the barrel. Finally, a tap is fixed to the bottom of the drum and the top of the pipe.
The process begins when dirty water is poured in to the barrel. After that, the water goes through the filter and up the pipe in to the drum, where it is stored. Then, when the tap in the drum is turned on, clean drinking water comes out.
The system shows how natural materials and basic equipment can be used to produce drinking water in just a few stages.

The rendered diagram explains
The rendered diagram explains a way in which water filter is desgined and the process of producing clean drinkable water.
Overall, it is simplest form of water filter which undergoes scores of steps, beggining with pouring of impure water into one tank and ending up with potable water in another tank.
First of all, impure water is poured into the cylinderlical (iron/steel/plastic) tank by removing its circuler shaped lid. Next, dirty water gets divided into three layers of sand, charcoal and gravel. The top most layer is sand and the bottom one is gravel where as, charcoal is in centre.
In the next step, using an angled steel pipe, water gathered in bottom part of tank is sucked by pipe. Where pipe have its rear part and it goes stright up over the three layers with slight bend in between the water pipe then, it nose dives into another tank which is placed next lower to first tank. Finally, second water tank have nozzle on right side from where purified water can be taken out for drinking.
