  14. 14. Sewer mining is the process of tapping into a sewer (either beforeor after the sewage treatment plant) and extracting sewage, whichis then treated and used as recycled water. Some sewer miningby-products may be acceptable for return to the sewerage system.Recycled water is treated so it’s safe to use. 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. The demand for drinking water can besignificantly reduced, by replacing it with recycled water madeavailable through sewer mining processes.
