Usage Guidance

  • This metric is intended to capture the wastewater derived from an organization's productive/operational processes that is treated.
  • Wastewater is water that carries wastes and is usually a mixture of water and dissolved or suspended solids.
  • Treatment for wastewater refers to the goal of achieving improvements in the quality of the wastewater before the remaining water is discharged back to the environment. The treatment process may reduce suspended solids, biodegradable organics, pathogenic bacteria, and nutrients. There are typically three levels of wastewater treatment: primary (mechanical), secondary (biological), and tertiary.
