IID bill payment basics
IID is the Imperial Irrigation District, a water and power utility serving parts of California's Imperial Valley. You can pay your IID bill through their website, by phone, by mail, or in person at a payment location. The method you choose depends on how quickly you need the payment posted and whether you prefer online or offline options.
IID bills arrive monthly and show your account number, the amount due, and the due date. Payments made online typically post within one business day. Payments by mail take longer — usually five to seven business days from the date you mail it — so plan ahead if your due date is approaching.
You do not need to create an online account to pay a one-time bill, though having an account makes it easier to track your balance and set up automatic payments. IID does not charge a fee for standard online payments made through their website.
Key Takeaways
- IID bills can be paid online through their website, by phone at 760-852-3424, by mail, or at authorized payment locations without creating an account.
- Online payments post within one business day and carry no fee when made through IID's official website.
- Mail payments take five to seven business days, so send them at least a week before your due date to avoid late fees.
- Setting up automatic payments through your bank or IID's website prevents missed due dates and removes the need to pay manually each month.
Paying online through the IID website
Go to iid.com and look for the "Pay My Bill" or "Online Bill Pay" link on the homepage. You will need your IID account number, which appears on your bill, and the amount you want to pay. The website accepts debit cards, credit cards, and bank account transfers.
Enter your account number and the payment amount, then choose your payment method. If you use a debit or credit card, you will see the payment posted within one business day. Bank account transfers (ACH payments) also post within one business day and may have lower fees than card payments, depending on your bank.
After you submit payment, the website shows a confirmation number. Save or print this number in case you need to reference the transaction later. If the payment does not post within two business days, contact IID customer service at 760-852-3424 to verify the transaction went through.
Paying by phone or automatic payments
Call IID customer service at 760-852-3424 to pay by phone. Have your account number and payment method (debit card, credit card, or bank account) ready. Phone payments post within one business day. IID's automated system is available 24 hours a day, or you can speak to a representative during business hours.
To set up automatic payments, log into your account on iid.com or call 760-852-3424. You can arrange for IID to withdraw the full bill amount or a fixed amount each month from your bank account. Automatic payments remove the risk of forgetting a due date and typically post on the date you specify.
If you set up automatic payments, review your bill each month to make sure the amount is correct. If your usage changes significantly, you may need to adjust the automatic payment amount or switch back to manual payments for that month.
Paying by mail
Write a check or money order payable to Imperial Irrigation District. Include your account number on the check. Mail it to the address shown on your bill — typically the IID Payment Processing Center in your region. Do not mail cash.
Mail payments take five to seven business days to reach IID and be posted to your account. If your due date is fewer than seven days away, do not rely on mail. Late fees explore if payment is not received by the due date, even if you mailed it on time.
Keep a copy of the check or money order number and the date you mailed it. If you need to confirm the payment was received, call customer service with this information and your account number.
In-person payment locations
IID accepts payments at authorized payment centers and some retail locations in the Imperial Valley. Check iid.com for a list of current payment locations near you, as these change periodically. In-person payments are posted when ready or within one business day.
Bring your bill or account number and the payment amount in cash, check, or debit card. Some locations may charge a small fee for credit card payments. Call ahead to confirm the location's hours and accepted payment methods.
Late payments and past-due bills
If your payment is not received by the due date shown on your bill, IID charges a late fee. The amount varies but is typically a percentage of your bill or a flat fee — check your bill or contact IID for the exact amount in your area.
If your bill becomes significantly past due, IID may disconnect your water or power service. You can request a payment arrangement if you cannot pay the full amount at once. Call 760-852-3424 to discuss options. IID may allow you to pay in installments or defer part of the payment if you may have access to for information programs.
If your service is disconnected, you will need to pay the past-due balance plus a reconnection fee to restore it. Reconnection typically takes one to three business days after payment is received.
