About Towering House Environmental Engineering PC
Towering House Environmental Engineering PC, an Indian Economic Enterprise and Native American-owned environmental engineering firm based in Las Vegas, Nevada, provides wastewater treatment design, feasibility studies, and water infrastructure engineering services to the Indian Health Service as a prime contractor under full-and-open competition (no set-asides used). The company is also certified as a Minority Owned Business, Veteran Owned Business, and Service Disabled Veteran Owned Business.
The vendor's federal footprint is narrow and specialized. All three awards in the source data come from the Indian Health Service, carrying a combined potential value of $815 thousand obligated in full. The company works exclusively with tribal nations on water and sanitation infrastructure. Recent work includes a $265.8 thousand firm fixed-price purchase order (April 2026) for design of fifteen advanced individual wastewater treatment systems for the Manzanita Band of Kumeyaay Nation in Sacramento, California, scheduled for completion by April 2027; a $234 thousand feasibility study (June 2024, completed November 2025) for the Manzanita Band of Mission Indians Sanitation Facility to guide design and construction activities aligned with EPA funding requirements; and a $315.4 thousand design services contract (September 2023, extended to August 2025) for main and canyon water storage facility repairs for the Iipay Nation of Santa Ysabel. All three are purchase orders carrying firm fixed-price terms with no competitive set-aside designation.
Activity is sparse — one award per year across 2023, 2024, and 2026 — with a single recompete exposure of $266 thousand in the next twenty-four months (the April 2027 Manzanita Band wastewater treatment systems project). The vendor operates as a 100% prime contractor with no subcontract footprint in the source data. Capability concentration lies in water supply, wastewater treatment, and pollution abatement infrastructure design for tribal nations served by the Indian Health Service.
