Budget estimate

$200,000 – $500,000

The RFP does not disclose a total contract ceiling, but typical residential septic‑tank cleaning costs range from $300 to $800 per unit. Assuming the Standing Rock Chapter comprises roughly 300 homes, the total contract value could fall between $90,000 and $240,000. Adding travel, equipment, disposal fees, bonds, and overhead pushes the likely award amount into the $150,000‑$500,000 range. Therefore a reasonable estimate is $200k‑$500k.
