Proposal for Septic tank cleaning services for Klagetoh Chapter

The Klagetoh Chapter of the Navajo Nation is seeking a qualified contractor to provide comprehensive septic‑tank cleaning services for homes on approved leases within the Chapter’s jurisdiction. The contractor must supply its own water for pumping, perform excavation when needed, inspect and replace baffles and filters, dispose of waste responsibly, and deliver detailed service reports while leaving a portion of liquid to maintain tank microbiology. Four sealed proposal sets are required, with separate sealed envelopes for cost and optional services, and all submissions must be mailed physically by the deadline. Preference is given to certified Navajo businesses, and all costs must include the Navajo sales tax. • Mandatory services include full septic‑tank pumping, baffle inspection/replacement, excavation assistance, waste disposal, and post‑service reporting. • Proposals must be submitted in four sealed copies plus separate sealed cost and optional‑services envelopes; electronic submissions are prohibited. • Evaluation requires a minimum qualifying score of 35 points before cost proposals are opened, with award expected shortly after the September 11 2026 deadline.
