The EPA is conducting a nationwide inventory of water service lines. Every water system needs every address to check their pipes and report their results, regardless of what they find. Please use the QR code in the flyer, or go to survey.SDWaterPipes.com, to complete a short 5-minute survey and take a picture of your water service line. The area to be tested will be the first 18 inches of pipe before the water meter (your water meter is normally in the lowest level of your home). If you need assistance please call the Madison Water Department at (605)256-7515, option 4.
