| RainHarvest System's demonstration of a downspout first flush diverter. |
In this project, rainwater is being collected as it runs off the roof of a shed. The initial rainwater may be contaminated from things on the roof such as pollutants, bacteria, and debris. These things can damage the irrigation system and may even cause harm to the crops. The purpose of a first flush diverter is collect a certain volume of the initial rainwater and prevent it from being stored. A ball floats in the diverter collection chamber. After the diverter collection chamber is full, the ball floats to the top, closing the diverter off, and allowing any subsequent flow of water to be stored for irrigation. This type of filter was chosen because of its simplicity, cost, and effectiveness.

Drip irrigation is a method of watering crops by allowing water to drop to the roots of plants through a network valves, tubing, and emitters. This method has many benefits that include: reduced water loss from evaporation and wind, low water usage, and decreased groundwater pollution.
