A machine separates the one percent of solid matter left in the effluent at the Riverside Park Water Reclamation Facility on Feb. 12, 2019. The water is expelled from directly underneath the solid matter, and the solids continue onward to wastewater digesters where they will ferment before continuing on to a secondary system of filtration to reduce pollutants.

The Riverside Park Water Reclamation Facility is seen from the top of a digester on Feb. 12, 2019. Visible are the secondary filtration systems and aeration basins where biological matter is processed. By 2021 the far end of the facility will have a tertiary membrane system, aimed to drastically reduce pollutants that pass through.
