Customers that draw water from public bulk water stations need to apply for an account allowing them to obtain water from that source.

To apply for a bulk water account, you will need:

  • A person with signing authority for the account holder contract.
  • $25 for every access card issued. You will be required to have an access card for each vehicle that will use the bulk water service.
  • A refundable security deposit may also be required at the time of application.
  • To modify your vehicle/tank to fit an Approved Air Gap (AAG) to prevent contamination of the public water supply.
