Budget estimate

$2,500,000 – $10,000,000

The budget for this contract is likely to be substantial, given the 5-year duration and the fact that it involves the provision of polymer for wastewater treatment at a large facility. The exact amount will depend on the bid price and the quantity of polymer required. However, based on industry standards, a rough estimate for a 5-year contract could be in the range of $500,000 to $2 million per year, depending on the scope of work and the bidder's pricing. Factors that may influence the likely payment range include the cost of the polymer, the frequency of delivery, and the level of service required.
