ATTENTION: Please be advised that it is unlawful to pump groundwater/rainwater into the sewer system.
Many homes experienced a back up of sewer water into their houses during those rain events. Sump pump water should be directed outside of the house and not connected to the sewer system.
The system is more than capable of accepting normal sewer usage. However, when the sewer is overwhelmed it will back up and flood your house with a mix of rain and sewer water potentially causing thousands of dollars worth of damage. If you suspect or know that your drainage system is set up this way, please rectify the situation.
