How to pay Santa Margarita District water bill online step by step
If this is your first time paying SMWD online, begin from the official Pay Bill page. This prevents confusion between the regular SMWD payment portal and the separate San Juan Capistrano customer payment link.
Open the official SMWD Pay Bill page
Go to the Santa Margarita Water District Pay Bill page here: smwd.com/396/Pay-Bill.
Choose the correct customer group
If you are a San Juan Capistrano customer, use the San Juan Capistrano-only payment link. All other SMWD customers should use the main SMWD payment link.
Open login, register, or one-time payment
The SMWD Payment Portal lets customers log in, register as a new user, recover username/password, or use a one-time payment route.
Enter account details from your bill
Keep your latest SMWD bill nearby. Enter your customer or account information exactly as printed so the payment posts to the correct account.
Review the account and payment amount
Check the service account, balance, and payment amount before submitting. If something looks wrong, contact Customer Care before paying.
Save the payment confirmation
After payment, save the receipt, confirmation number, or screenshot. Keep it until your SMWD account balance updates correctly.
San Juan Capistrano warning: Do not use the main SMWD payment link if your bill is specifically for San Juan Capistrano and the SMWD Pay Bill page directs you to the separate San Juan Capistrano payment option.
