20' Combi Fresh - Sewage Water Tank

20' Combi Fresh - Sewage Water Tank

The 20-foot combi tank is a smart dual-compartment solution engineered to handle both wastewater and fresh/service water in a single, compact unit. Built from robust, coated steel and equipped with thermal insulation (mineral wool), this combi tank ensures efficient, hygienic, and environmentally compliant water and waste management.
Its structure includes two separate chambers – 60% dedicated to sewage and 40% to clean water – allowing independent filling and drainage. Two dedicated inlet pipes, a 3000 L/h high-capacity pump, and secure ventilation systems enable easy connection to sanitary containers and mobile facilities.
Ideal for construction sites, events, emergency operations, and modular camps, the tank offers flexibility, safe handling, and optimized space use – especially in locations where centralized infrastructure is unavailable.
