Budget estimate

$67,500 – $90,000

The estimated annual amount of Liquid Ammonium Sulfate required is 135,000 to 180,000 pounds. Assuming an average price of $0.50 per pound, the total estimated annual cost would be $67,500 to $90,000. However, this is just an estimate and the actual cost may vary depending on the bidder's price and other factors. The contract term is for one year, with the option for OWASA to extend for two additional one-year periods, so the total potential budget over three years could be $202,500 to $270,000.
