This morning, Secretary of Energy Dr. Steven Chu visited several homes in the solar village. WaterShed team members showed him the constructed wetlands and liquid desiccant waterfall (LDW). Constructed wetlands are artificial filtration wetlands, which provide critical animal and plant habitat as well as mitigate impacts of waste water and storm water run-off. The liquid desiccant works with the other heating and cooling systems by absorbing excess humidity from the air.
