Single Mains Toilet Waste Tank – 500 Gallon, Steel Construction

This single mains toilet waste tank – 500 gallon, steel construction provides robust, reliable waste storage for portable toilet systems, site welfare units, and remote facilities. For example, you can connect this tank directly to mains toilet systems on construction sites, camps, or event venues. Therefore, this unit eliminates frequent pump-out requirements and reduces maintenance costs.

Why Choose a 500 Gallon Steel Waste Tank?

Smaller waste tanks require frequent emptying, which increases operational costs. In contrast, this 500-gallon capacity tank stores significantly more waste, reducing pump-out frequency by up to 75%. Consequently, you save on transport and disposal fees. Moreover, the steel construction provides exceptional durability for demanding site conditions. Thus, you gain both capacity and longevity.

Key Features of This Toilet Waste Tank

The steel construction and 500-gallon capacity make this waste tank stand out. For instance, the carbon steel tank measures approximately 4 feet in diameter with a 5-6 foot straight side, delivering reliable 500-gallon nominal capacity . Similarly, the steel body resists impacts and harsh site handling. Furthermore, we can supply bunded options with 110% secondary containment for environmental compliance . Finally, the tank includes multiple inlet and outlet ports for flexible mains connection.

500 Gallon Capacity – Reduced Pump-Out Frequency

The 500-gallon capacity transforms waste management efficiency. For example, a typical site toilet might generate approximately 50-100 gallons of waste per week. Likewise, this 500-gallon tank stores 5-10 weeks of waste, dramatically reducing service calls. Furthermore, you can connect multiple toilets to a single tank using appropriate pipework. If you manage a construction site or event venue, this capacity means fewer truck visits and lower operating costs.

Steel Construction – Built for Site Conditions

Steel construction makes this waste tank exceptionally durable for outdoor use. First, carbon steel (grades 09G2S or equivalent) provides high structural strength . Second, manufacturers apply anti-corrosion coatings [zinc-filled, polyurethane, or epoxy] to protect against rust and chemical attack . Third, the robust construction withstands pressure washing, site movement, and heavy handling. Finally, steel tanks typically last 20+ years with proper maintenance. Therefore, you can place this tank anywhere without worrying about premature failure.

Bunded Options – Secondary Spill Containment

Environmental compliance requires spill protection for waste storage. For example, we offer double-wall bunded options that provide 110% secondary containment . Likewise, bunded tanks meet UL 142 specifications and Uniform Fire Code requirements. Furthermore, the bund catches any leaks from the primary tank and prevents ground contamination. If your site requires environmental compliance, choose our bunded version for peace of mind.

Mains Connection – Simple Site Integration

This tank connects directly to mains toilet systems for continuous operation. For example, standard inlet ports (typically 1-1/2″ to 3″) accept waste pipe connections . Likewise, outlet ports accommodate pump-out hoses for periodic emptying. Furthermore, the tank includes access hatches (12-24 inches) for inspection and cleaning. If you need a complete site welfare solution, we can supply the tank with full pipework and fittings.

What’s Included

First, every unit includes the 500-gallon carbon steel tank with anti-corrosion coating. Second, the tank comes with inlet and outlet ports (specify quantity and size at order). Third, a top manway (18-24 inches) provides access for inspection and cleaning. Fourth, we include lifting lugs or forklift pockets for positioning. Finally, the tank mounts on steel legs or a skid base for stable installation.

For instance, you can add a bunded double-wall tank for secondary containment. Likewise, you can add a pump-out assembly for easy waste removal. Furthermore, we can supply insulation and heating for cold-climate applications . Contact our team for custom configurations.
