Paideia School in Atlanta decided to add a 300 gallon tank to water the student garden and compost. The tank was designed to capture rainwater and condensation from the building. The system includes a 3P Rainus roof filter, a Rain Harvesting first flush diverter on the right, a floating filter, a p-trap to keep mosquitos in the tank and a Raintube covered by stone to keep rodents out. The system uses gravity to convey the water. Two spigots are provided. The lower spigot is for hose connection and the upper spigot for bucket filling. With the hot humid summers the tank should have plenty of water with the help of condensation.
