Portable Toilet Services - ZION National Park
INTERIOR, DEPARTMENT OF THE.DEPARTMENTAL OFFICES.NATIONAL PARK SERVICE CONTRACTING ACTIVITY · Response deadline: Thu, 03 Dec 2026
What the government is buying
The National Park Service is soliciting bids for portable toilet services at Zion National Park in Utah. This is a recurring services contract to provide, maintain, and service portable sanitation facilities within a high-traffic national park environment.
NAICS code 562991 covers "Septic Tank and Related Services," which includes portable toilet rental and servicing. Federal contracting in this category typically involves a combination of service delivery behaviors: scheduled waste pump-out, unit cleaning and restocking (toilet paper, hand sanitizer, deodorizer), unit delivery and removal, and emergency response for spills or malfunctions. At a major destination park like Zion— which receives several million visitors annually—contractors should expect significant seasonal volume fluctuations, with peak demand during spring through fall.
Because the metadata does not specify quantities, locations within the park, or service frequencies, see the solicitation for the complete statement of work, minimum unit counts, and performance schedule.

Who can bid
This solicitation is full and open competition with no small-business set-aside, meaning businesses of any size may submit offers. Large firms, small businesses, and socioeconomic program participants all compete on equal footing.
That said, small businesses in the portable sanitation industry can remain competitive through several structural advantages common to this sector: lower overhead structures, established regional service networks in southern Utah/northern Arizona, and specialized equipment fleets sized for park service contracts rather than massive municipal accounts.
If you are a small business considering this opportunity, verify your SAM.gov registration is active and that your entity has the correct NAICS code (562991) in its profile. No additional certifications are required for unrestricted competition, though past performance on federal or commercial contracts of comparable scale will factor heavily in evaluation.
How to put together a competitive bid
For portable toilet services in a national park setting, focus your proposal on operational reliability and environmental compliance:
Fleet and logistics: Demonstrate sufficient unit inventory, service vehicle capacity, and geographic proximity to support rapid response times. Zion's remote canyon location means travel distances and road restrictions affect pricing.
Environmental stewardship: The National Park Service prioritizes waste handling that protects watersheds and sensitive ecosystems. Detail your waste disposal permits, treatment facility relationships, and spill prevention protocols.
Seasonal staffing plan: Explain how you will scale labor for peak visitation (March–October) without service degradation during slower periods.
Past performance: Highlight comparable federal park contracts, state park agreements, or large-event servicing. Emphasize contracts with similar environmental constraints or remote logistics challenges.
Pricing structure: Federal service contracts often use fixed-price with economic price adjustment or indefinite-delivery requirements. See the solicitation for the specific contract type and pricing instructions.
