Located atop an entrance building at our Wastewater Treatment Plant, our green roof was the first in the area and serves as a demonstration project for others interested in learning about this green alternative to traditional roofing.
The roof is made of a several layers: a membrane that provides insulation and protection, a drainage layer, a filter mat, a soil layer, and lastly, a variety of vegetation.
The project was made possible by generous donations of materials and labor by Plant Connection, Metro Green Visions and Steven Dubner Landscaping. The roof, which measures 2,900 square feet, would have cost the ACUA approximately $72,500 to install.
Environmental and Financial Impact:
The green roof helps to retain stormwater runoff and insulates the building, which lowers heating and cooling costs. It also provides a natural habitat to the area's wildlife.
