1500-Gallon Capacity Slide-in Unit
When you need to cover more ground between dumps but still want the versatility of a drop-in package, the 1500-gallon truck tank from KeeVac Industries delivers. This is our largest slide-in to date, built for operators who’ve outgrown smaller units but aren’t ready to commit to a fully dedicated chassis-mounted truck. Fabricated in Denver since 2007, it carries the same fleet-ready quality that’s earned the trust of hundreds of septic and grease operations across the country.
More capacity means fewer trips to the dump site, longer routes between offloads, and more productive days, without sacrificing the move-it-when-you-need-to flexibility that makes a slide-in so valuable.
Why Step Up to a 1500-Gallon Slide-In?
A 1500-gallon slide-in bridges the gap between compact units and full septic builds. If you’re finding that a smaller tank has you offloading too often, this is the upgrade that pays for itself in saved time.
- Extended route capacity: A 1500-gallon vacuum truck tank keeps you working longer between disposal stops
- Drop-in versatility: Mount it on a compatible flatbed or chassis, then relocate it as your needs change
- Cost-smart expansion: Add serious capacity to your operation without buying another dedicated truck
- Weight-conscious build: 5454 aluminum construction keeps the unit strong without unnecessary load
