Wastewater treatment/reclamation facilities:

  • Remove solids – everything from rags and plastics to sand and smaller particles found in wastewater;
  • Reduce organic matter and pollutants – naturally occurring helpful bacteria and other microorganisms consume organic matter in wastewater and are then separated from the water; and,
  • Restore oxygen – the treatment/reclamation process ensures that the water put back into our rivers or lakes has enough oxygen to support life.

Wastewater treatment/reclamation basically takes place in three stages:

  1. Primary treatment, which removes 40-60% of the solids.
  2. Secondary treatment, which removes about 90% of the pollutants and completes the process for the liquid portion of the separated wastewater.
  3. Solids Processing or Sludge Management, which treats and disposes of biosolids.
