Description

This solicitation seeks a qualified firm to conduct a comprehensive water resources and wastewater feasibility study for a proposed 86‑acre Thoreau Travel Center and Hotel on Navajo Nation fee lands. The study must evaluate regulatory requirements, on‑site water‑supply and wastewater‑treatment options, water‑quality compliance, demand modeling, permitting pathways, cultural clearances, and provide cost estimates and final recommendations. • Perform data collection, regulatory review, and on‑site investigation of hydrogeologic conditions. • Develop water‑demand models and analyze both public‑system connection and on‑site groundwater development options. • Conduct water‑quality sampling plans, propose treatment solutions, and evaluate wastewater treatment/disposal alternatives. • Produce a permitting strategy that addresses Navajo Nation, federal (EPA), and New Mexico requirements, including cultural clearance processes. • Deliver draft and final reports with conceptual cost estimates and a clear recommendation for the most feasible solution.

Budget estimate

$150,000 – $350,000

Based on typical costs for a multi‑disciplinary feasibility study of this scope (hydrogeology, demand modeling, regulatory review, permitting strategy, and full reporting) on a remote 86‑acre site, the fee is likely between $150,000 and $350,000. Lower end assumes a lean team and limited field work; higher end assumes extensive sampling, multiple design alternatives, and detailed cultural‑clearance coordination.
