Budget estimate

$5,000,000 – $10,000,000

The scope covers a full plant upgrade including civil works, mechanical/electrical equipment, and specialized odor control systems. Comparable municipal WWTP upgrade projects in the Midwest typically range from $5 million to $12 million in construction value. Considering the extensive scope and the need for specialized equipment, a reasonable estimate for the contractor revenue would be between $5 million and $10 million. Factors influencing the final amount include material costs, site conditions, and any schedule acceleration requirements.
