Hospitality projects generate large volumes of graywater with or without onsite laundry. Many hotels and resorts also have significant irrigation and cooling water demand that can be served by reclaimed water. We have found that many coastal resorts in areas without adequate potable supply often rely on reverse osmosis of seawater to provide for potable use. Graywater reuse can offset significant capital and lifecycle costs in these situations where RO system size can be reduced.
