The City of Painesville Water Pollution Control Plant is located on the Grand River off of N State Street near the City's limit line. The Water Pollution Control Plant (WPCP) cost-effectively treats the wastewater from homes, businesses, industries, schools and agencies of the City of Painesville, which equates to roughly 20,000 people.
Thanks to 14 dedicated employees, the Painesville WPCP runs 24/7. Trained professionals – operators, lab technicians, maintenance crew members and administrative staff – ensure the WPCP and pump stations that supply wastewater operate effectively. At the plant, state licensed operators are responsible for the daily operations; lab staff perform analysis on internal processes and products; and crews of mechanics and electrical staff maintain and repair equipment. Our goal is to provide the City with the best wastewater treatment service available while operating as efficiently and effectively as possible.

Wastewater and stormwater coming into the plant undergoes a series of treatments:
- Preliminary treatment: large debris like rags, paper, plastics and leaves are removed. Grit and screenings are removed for landfill disposal.
- Primary treatment: skimming and settling occurs to remove sludge, heavy metals and scum, which are pumped to a solids handling process (anaerobic digesters).
- Secondary treatment: a biological process that consumes suspended solids, ammonia-nitrogen and dissolved organic material, leaving the remaining water or secondary effluent at least 85% cleaner than when it entered the plant.
- Tertiary treatment: secondary effluent is polished using sand beds to remove suspended solids. The process is an advanced treatment design that creates a high quality discharge to the Grand River.
Disinfection: destroys most remaining pathogens, or disease-causing bacteria, before the final effluent is discharged to the Grand River.
