Barge Schedule

We have storage facilities and delivery personnel on San Juan, Lopez and Orcas Island. We service ALL of the outer islands by barge. Our outer island customers have been utilizing out Tank Monitoring System. Having real time data, the monitors have eliminated the guessing game. We know how much and when we have to schedule a barge. This system, along with our storage facilities on San Juan, Lopez and Orcas has helped us drastically reduce the costs to our outer island customers
