Where to pay your San Marcos utilities bill

SDG&E bills arrive monthly and can be paid online through their website, by phone, by mail, or in person at payment centers. The City of San Marcos Water Department also bills monthly and accepts payments online, by phone, by mail, or at their office. Both utilities offer automatic payment options that deduct money from your bank account on a date you choose.

Understanding your bill and spotting errors

Your SDG&E bill shows your usage in kilowatt-hours (kWh) for electricity and therms for gas, broken down by rate tier. The first section of your usage costs less per unit; higher usage costs more per unit. Your bill also lists any discounts or assistance programs you are enrolled in, such as CARE (California Alternate Rates for Energy) or FERA (Family Electric Rate Assistance).

The City of San Marcos Water Department bill shows your water usage in units called hundred cubic feet (HCF), plus sewer charges based on your water use.

If you see a spike in usage that does not match your habits, check for leaks or meter errors — contact the utility to request a meter inspection if something looks wrong.
