Elmich - Modular tank system
VersiTank Rainwater Harvesting Tank System Malaysia
VersiTank modules form a high-void underground structure that can be configured for project storage or attenuation requirements. The complete design includes the modules, geotextile or liner, access, inlet treatment, overflow and maintenance provisions.

Typical application
VersiTank in the Build-Up
VersiTank is a modular below-ground structure used within rainwater storage, detention or infiltration designs. The modules are only one part of the system. Liners or geotextiles, inlet treatment, ventilation, access, pumps and controlled outlets depend on the intended use.
Tank volume should be calculated from the connected catchment, local rainfall pattern, reuse demand or discharge target. Burial depth, groundwater, soil, nearby foundations and traffic loading also affect the civil and structural design.

- Size the system from rainfall, catchment and demand data.
- Define traffic loading and burial depth.
- Include pre-filtration and maintainable access.
- Confirm groundwater, soil and structural conditions.

Frequently asked questions
Before Ordering VersiTank
Can VersiTank be used for rainwater harvesting?
It may form the modular storage zone within a designed harvesting system. The liner, filtration, pump, overflow, access and water treatment are selected around the proposed reuse.
How much VersiTank storage is required?
Storage depends on catchment yield, rainfall, demand, overflow criteria and available space. A civil or hydraulic designer should complete the project calculation.
Can VersiTank be installed below vehicle areas?
Loading and burial conditions must be checked against the current selected system data and the project design before it is specified below trafficable areas.
