10-Foot 4500L Basement Septic Tank | For 3x2.5m Sanitary Container

Integrated 10' Sanitary Retention Tank – Autonomous Sanitation Solution for Mobile Modules
 This 10-foot basement septic tank is a new, 4,500-liter steel technical tank. Designed specifically to serve as a structural base for mobile modules, it allows the installation of plumbing units, shower blocks, or standard-sized sanitary containers (3m x 2.5m) on sites without direct connection to the municipal sewer system or mains drainage.
 Thanks to its robust design, the sanitary container can be easily and directly placed on top of the septic tank. This vertical configuration offers a space-saving, self-contained sanitation solution, ideal for construction sites, festival grounds, campsites, or isolated areas.
