Recycled waterproduced from a sewer mining operation is commonly used toirrigate sports fields, parks and golf courses. It can also be used insome commercial buildings and industrial sites. New Water Sources:Sewer mining reduces the stress on waterways by capturing some Sewer Miningof the nutrients that would otherwise be discharged from sewagetreatment plants.
