The Village of Mundelein is pleased to bring you online options for payment of your water/sewer bill. Customers are now able to pay their bi-monthly water/sewer bill, set up recurring payments and view their account transaction history by clicking here or by clicking on the image to the right. Payment options available include all major credit cards, debit cards and electronic checks. A 4-digit PIN printed on the face of your water bill is required to register for online payments. Customers will not be charged any convenience fees for these transactions. You will receive immediate payment confirmation and a printable receipt for your records. This new on-line program is in addition to customers currently enrolled in the Village’s Mainline Pay program – no action is required for current Mainline Pay customers. If you have any questions, please contact Water Billing at 847-949-3245 or firstname.lastname@example.org.
