Alternate solutions:







In this solution, the drainage pipe leads directly to the reservoir. A fine mesh net filters out all detritus coming through the drain, and bacteria in the reservoir tank rids the water of unwanted microorganisms. The pump will bring the water out from the top of the reservoir tank to be delivered to the rest of the tank through the pipe system.


In this solution, the drainage pipe leads down in to the reservoir tank. Upon entering the reservoir tank, the water runs down a layer of gravel, which filters out the larger pieces of debris. The water then flows through a fine mesh net, which filters out the remaining smaller objects. The water delivery pipe system is located at the bottom of the tank in the scenario so that the filtered water on the bottom is transferred to the rest of the tank.
















In this solution, the filter is placed in the actual drainage pipe. The water is sent through a layer of gravel as well as a fine mesh net. The gravel blocks all large pieces of debris while the mesh net filters out the smaller objects. Once the clean water enters the reservoir tank, it is sent through the pipe system using the pump to be delivered to the rest of the tank.


In this solution, the filter is placed in the drainage pipe as well as in the reservoir tank. The filter in the drainage pipe is made of a layer of gravel, to filter out the larger objects. A fine mesh net as well as a bacteria culture are in the reservoir tank to filter out smaller pieces of debris and to get rid of unwanted microorganisms. The water delivery pipe system is located at the bottom of the reservoir tank to make sure that only clean water is sent to the tank.
