At Four Rivers Sanitation Authority (FRSA), we’re proud to play an important role in keeping our local watersheds balanced by cleansing wastewater – but that’s not all we do. Since 1932, we’ve used nature’s way of cleaning water to keep people and our economy healthy. If you’ve ever wondered what happens to the water that drains out of your shower at home or sink at work, take a look at the first video in our series, “Why Four Rivers?”
