RecPro Combo: 10 & 16 Gallon Tanks

The RecPro 10 & 16 gallon combo provides compact storage for small food trucks or retrofitting projects where space is at a premium. The smaller pairing is ideal for concession setups that generate moderate gray water and limited black water. These tanks are pressure tested and manufactured in the United States, aligning with reliability and hygiene standards essential to food service operations. Before first use, thorough cleaning is recommended to remove any manufacturing residues. Installers should consider access for routine cleaning and a secure mounting system to prevent movement during travel.
RecPro Combo: 30 & 42 Gallon Tanks

This larger RecPro set expands capacity for food trucks with higher output or longer routes between service stops. The 30 and 42 gallon tanks support extended operations, reducing the frequency of emptying while keeping gray and fresh water separate. The package carries NSF approval and is built in America, with pressure testing to ensure long-term durability in mobile environments. As with any holding tank, proper seals and venting are crucial to prevent odors and ensure sanitation inside your truck. Regular cleaning schedules should be maintained to meet health guidelines.
RecPro Combo: 21 & 30 Gallon Tanks

RecPro’s 21 & 30 gallon combination suits mid-sized food trucks that require balanced capacity for daily use and ease of maintenance. The TEI certification and IAPMO compliance emphasize adherence to industry standards, which can facilitate inspections and reduce compliance concerns for mobile food vendors. Like other holds tanks, ensure cleanout ports and fittings are accessible. A well-planned layout reduces sloshing and improves stability when the vehicle is in motion, contributing to safer and more efficient waste management on the road.
Class A Customs 35 Gallon Tank

The Class A Customs 35 gallon tank is a versatile option for food trucks needing a robust, NSF-approved solution. Its dimensions and built-in fittings support straightforward installation in a variety of trailer configurations. The dual-use capability—storing either fresh or gray water—can simplify inventory management for operators who prefer a single tank for multiple functions. The tank’s construction emphasizes watertight seals and durable materials to resist the vibrations of mobile service. Proper venting and secure mounting remain essential to prevent leaks and odors during travel.
Ameri-Kart 36 Gallon Fresh Water Tank

The 36 gallon Ameri-Kart option offers a larger fresh water reservoir with BPA-free materials for potable use in food trucks and RVs. Its multiple installation options and standard fittings provide flexibility in design, allowing operators to adapt the tank to different trailer layouts. With weather-resistant plastics and leak-proof construction, this tank supports long-term hygiene and reliability. While primarily a fresh water tank, thoughtful planning ensures it remains distinct from any gray water holding components to avoid cross-contamination and simplify maintenance routines.
Buying Guide: Key Purchase Considerations For Food Truck Waste Water Tanks
- Capacity alignment: Match tank size to your daily water usage and the number of service days between empties. Larger fleets or higher-volume menus benefit from bigger tanks, but space constraints on trailers may limit options.
- Material and build quality: Look for BPA-free plastics, NSF or IAPMO approvals, and pressure testing. Durable construction reduces the risk of leaks and odors during travel and cleaning.
- Fittings and installation: Consider the number and type of fittings (NPT sizes, vent ports, inlet/outlet locations). Tanks with multiple fitting options offer flexibility for various trailer layouts and pump configurations.
- Compliance and sanitation: Ensure the chosen tanks meet local health department guidelines and industry standards. Certification signals good manufacturing practices and safer storage of potable water when used for drinking and cooking in some setups.
- Maintenance and cleaning: Favor tanks with accessible cleanouts and minimal seams. Regular cleaning schedules and a clear plan for emptying gray and fresh water reduce odors and contamination risks.
- Portability and mounting: Evaluate mounting hardware compatibility, weight distribution, and how the tank behaves during transit. Secure mounting prevents movement that could damage fittings or cause leaks.
- System integration: If your trailer uses a combined gray and black tank system, confirm compatibility with your pump, discharge outlet, and any waste transfer equipment. Some combos offer built-in fitting options to streamline installation.
- Warranty and support: A robust warranty and responsive customer support help address installation questions and potential replacements after purchase.
When selecting a waste water holding tank for a food truck, weigh the balance between capacity, space, and ease of maintenance. The five options outlined above cover a range of sizes and configurations, all designed to withstand mobile usage while maintaining sanitation and regulatory compliance. By aligning tank specifications with your kitchen workflow, you can simplify waste management and keep focus on service quality on busy days.
