How much was found?

From these inflow investigations, we found a total of 181 sump pumps and 30 drains directly connected to the sewer. Sump pumps have the potential to be connected to the sewer because of an unknown discharge location or flexible discharge pipe. The confirmed illegal connections have the potential to discharge 1.55 million gallons of inflow during a storm, approximately 15% of the Grass Island Wastewater Treatment Plant's average daily flow. This is clearly a significant issue for our collection system and treatment plant facilities.
