Bio Blocks

The City of Flint is seeking vendors to supply bio‑block treatment media and industrial‑grade sodium bicarbonate for its water‑pollution‑control facilities under a three‑year contract. Supplies must be stocked and available for rapid (≤48 hour) delivery upon request, with quantities approximated but not guaranteed. Bidders must submit a full proposal package, including pricing for each of the three contract years, qualifications, references, insurance certificates, and a signed acknowledgement of the addendum. Local Flint vendors receive a price advantage, and the contract may be split or awarded to multiple vendors. • Provide E100 industrial sewer granules (≈24 × 50 lb pails) and Free‑Flow Bio Blocks (≈12 × cases of 4×10 lb units) on a 48‑hour response basis. • Supply 100 × 50 lb bags of industrial‑grade sodium bicarbonate, also on short‑notice delivery. • Submit original signed proposal, two unbound copies, and an electronic copy by June 10, 2026; questions due by June 3, 2026.
