Water Efficiency: Our Water Footprint

Currently GAF is baselining its complete water footprint and will establish a 2030 water efficiency goal in 2023. GAF has led major water conservation projects across our plant network, including efforts in our Shafter, California shingle and mat plants; our Mt. Vernon, Indiana shingle and modified bitumen plant; and our Tampa, Florida shingle plant. In our Shafter plants, we developed a new process which resulted in a 100% closed loop water system that repurposes over 5 million gallons of processed water annually from the reverse osmosis water purification system, resulting in zero waste water discharge from the plant. The implementation of the new system also reduced our overall water consumption by an average of 194,000 gallons per month. Similar to efforts in Shafter, our Mt. Vernon shingle and modified bitumen plant and our Tampa shingle plant have developed partial and fully closed loop wastewater systems, respectively. These efforts have enabled GAF to reduce its cooling water use by up to 15% in Mt. Vernon and recirculate our cooling water for reuse to help work towards a zero discharge plan in Tampa.
