Customer deposits are only requested at the time of starting service if required credit criteria are not met. For residential accounts only, a deposit is reviewed 13 months from the date it was paid in full and, if the account qualifies for a refund, interest is calculated on the deposit and both amounts are applied as a credit to your account.
If there is a balance on your account at that time, it will be deducted from this credit and any remaining credit will be applied to future bills.
An account will normally qualify for a refund of deposit if there have been no more than two "48 hour" notices in the last twelve months. A "48 hour" notice is a notices that your service will be turned off unless you pay your balance due within 48 hours.
If you do not qualify for a refund after 13 months, your account will be re-evaluated monthly, and when you do qualify your deposit will be credited as described above.
