The final step of the water treatment process is filtration.
We run the treated water through rapid gravity filters using dual media filters (anthracite and coal over sand) to remove any remaining particles that may still be suspended in the water. The water is passed through these filters at a controlled rate and the remaining particles are captured in the filters and removed from the water.
The filtered water is then collected and flows into one of our pump stations at the water treatment plant where it is then pumped and delivered to our member and customer cities through 77 different delivery points. The cities also do their own water quality testing once the water arrives and may perform additional maintenance procedures to ensure the highest water quality.
