Biosolids Removal and Disposal

The City of Yuma is requesting bids for biosolids removal and disposal services from its two water treatment facilities through land application in compliance with state and federal regulations, with bids due August 6, 2026.

The Figueroa Water Pollution Control Facility produces 40,000 to 80,000 gallons of Class B biosolids daily, and the Desert Dunes Water Reclamation Facility produces 5,000 to 40,000 gallons of Class B biosolids daily. The awardee must remove and dispose of biosolids through land application, providing all equipment, acreage, and facilities necessary for compliant disposal at no additional cost to the City. Comprehensive documentation is required, including detailed land application methods, hauling schedules, site plans with proposed disposal locations, and all necessary state and federal permits. A critical requirement is submission of a detailed Dry Ton Biosolids Alternative Disposal Plan demonstrating capability to manage biosolids through an alternative method — such as landfill, monofill, or incineration — if primary wet-ton land application becomes unviable. All biosolids become the property of the bidder upon leaving the treatment plant.

The contract is structured as an annual agreement with firm, fixed pricing held for 12 months following notice of award, renewable for four additional one-year terms. The awardee must maintain Commercial General Liability insurance with limits of $2,000,000 general aggregate and $1,000,000 per occurrence, Business Automobile Liability with $1,000,000 combined single limits (or $3,000,000 if hazardous materials are transported), and Workers' Compensation coverage. Compliance obligations include extensive environmental, monitoring, and reporting under 40 CFR Parts 257, 258, and 503; Arizona Administrative Code Title 18 Chapter 9 Article 10; and annual reports to the EPA, Arizona Department of Environmental Quality, and City officials detailing application sites, volumes, crops, and compliance certifications.
