Budget estimate

$500,000 – $2,250,000

The solicitation does not disclose a total contract value. Based on typical costs for residential OWTS units (approximately $10,000‑$15,000 per home) and assuming the Nazlini Chapter may require 50‑150 installations, the overall contract could range from roughly $500,000 to $2,250,000. Adding 6 % Navajo sales tax, bonding, and insurance costs, a realistic earning window for the contractor would be in the low‑mid half‑million to low‑two‑million‑dollar range.
