From the Littleton Independent:
The City of Littleton will send out the annual sewer and storm drainage utility bills in mid-June. Payment is due to the City of Littleton by Aug. 17. If full payment is not received by this date, a 25 percent penalty will be added to the remaining balance and a past-due bill will be mailed in September. The city will accept online credit card payments for the first time this year.
