Unilever recently constructed Surf Labahan, a filtration system that recycles grey water using debris left behind by typhoon Haiyan. Typhoon Haiyan destroyed entire communities in the central Philippine provinces of Samar and Leyte, and water supply in all affected areas was limited and sporadic.

Surf Labahan generates approximately 153 liters of recycled water per day for laundry use, so the limited supply of fresh water could be used for drinking and cooking instead. With simple technology, Surf was able to make every drop of water count, making laundry sustainable, one wash at a time.​
