Dual Tanks
Tank # 1
The main hurdle was connecting two rain water tanks separated by 75 feet, with the second tank sitting 15 feet higher than the first. This elevation difference made it impossible to maintain equal water levels, in dual rain tanks, using gravity alone. However, by employing multiple collection methods simultaneously, we devised an elegant solution.
Diverter Tank # 2
This increased storage has provided the homeowners with enough water to sustain their tomato plants throughout the growing season using low-pressure irrigation and a timer system. Not only are they thrilled with the sustainable benefits of using rainwater for their garden, but they also take pride in contributing to the city’s water management efforts through this utility program.
