Sump pumps are fairly common in area homes. Do you have a sump pump in your basement? Do you know what it pumps? If it is connected to the laundry, toilet, or other household “dirty” water source, the pump should discharge to the sanitary sewer. You can test your system to find out what you are pumping by running your below-grade water sources. If your pump kicks on, it might be an ejector pump. Call a professional before attempting to remove the lid and look into your pump as sewer gasses may escape into your home.
Remember: Grey water = sewer; clean water = stormwater.
