Budget estimate

$150,000 – $500,000

Based on the estimated quantity of delivery, which ranges from 1,500 gallons to 5,000 gallons bi-weekly, the total annual quantity can be estimated to be around 78,000 gallons to 260,000 gallons. Assuming an average price of $2 per gallon, the total annual cost would be around $156,000 to $520,000. However, this is a rough estimate and the actual cost may vary depending on the bid price and other factors.
