A Note About AutoPay Fees - Heights Water charges a small fee for use of AutoPay by ACH to offset our bank fees for providing this service. The fee is currently only 67 cents per bill (about four dollars a year). If you pay by credit/debit card, either as a one-time payment or through AutoPay, our card processing provider will add a processing fee of 3% or more per payment. Either way, AutoPay provides the convenience of never having to write a check and and never having a late payment!
