Biosolids Projects and Emergency Disposal

The City of Olathe's Environmental Services Division is soliciting proposals for a comprehensive biosolids management contract covering digester cleaning, wastewater lagoon dredging, and emergency sludge hauling services across two mechanical wastewater treatment facilities: Cedar Creek WWTF and Harold Street WWTF. Specific projects include secondary and primary digester cleaning at Harold Street (involving 40-foot diameter digesters with approximately 201,400 and 210,800 gallon capacities, respectively) scheduled for April 2026 and April 2027, and Lakestone Lagoon dredging with 8-12 inches of sludge removal in two phases (primary/northeast lagoon in July 2026 and secondary/southwest lagoon in August 2026). The RFP requires contractors to provide on-call emergency sludge hauling services with two-week mobilization capability for the 2026-2028 period, with proposals evaluated on Project Approach (30 points), Firm Personnel (30 points), Quality of Similar Work (20 points), and Pricing (20 points). Proposals must be submitted electronically through Bonfire by February 6, 2026, at 10:00 AM CST, with questions due by January 30, 2026, at 5:00 PM CST. All biosolids disposal must strictly comply with EPA 40 CFR Part 503 and OSHA standards, with current facilities generating approximately 1,400 dry tons annually at Cedar Creek WWTF and 234 dry tons annually at Harold Street WWTF.

The solicitation does not specify any specific set-aside designations or restrictions for disadvantaged enterprises. Contractors must submit a comprehensive proposal package including a notarized affidavit, vendor response form, W-9, and certificates of insurance with specific coverage limits: General Liability ($1,000,000 per occurrence/$2,000,000 aggregate), Business Auto ($500,000), Workers Compensation at statutory limits, and Professional Liability ($1,000,000 if applicable). The contract will be awarded for a three-year term, with anticipated City Council approval on March 3, 2026. Pricing submissions must remain valid for 120 calendar days from the RFP opening date and include separate pricing for standard and emergency mobilization rates, per-gallon pricing for volumes exceeding 10,000 gallons, lagoon dredging services, liquid sludge hauling fees, and mobile dewatering unit rental options. While specific budget ranges are not explicitly stated, the current biosolids management practices involve landfilling at Johnson County Landfill and composting into Class A product, suggesting potential substantial service volumes for the selected contractor(s).
