1. Primary Treatment
Solid particles & objects are captured in grit screens and primary clarifiers.
2. Aeration/Secondary Treatment
Wastewater is aerated to support growth of microorganisms that remove harmful pollutants.
Solids and microorganisms settle out in large basins.
4. Advanced Treatment
Wastewater flows through sand filters to remove fine particles.
Water is disinfected to remove any remaining pathogens then released back into creeks to flow downstream.
