Stormwater and Rainwater Modular Tanks
GS-Tanks are modular PP units for underground stormwater and rainwater storage. They can form attenuation, infiltration or reuse systems when the lining, connections and discharge arrangements are designed for the site. For shallow modular build-ups, see HOENSOEY Cells.
GS-Tanks Manufacturing and Project Supply
- GS-Tanks support project orders and supply for dealers, wholesalers and distributors. Share the application, storage volume and available space to identify the relevant module options.
- The technical specifications list virgin polypropylene or 100% recycled PP. Review the declared data for the selected model and material alongside installation depth, loads and site conditions.
- For a quotation, provide the model, quantity, destination and delivery schedule. Product details, available documents and packing requirements can then be reviewed.

UP TO 55 YEARS OF SERVICE LIFE
The stormwater module is mainly made of high purity PP with great toughness. The modular rainwater storage tanks don’t easily react with acid or vinegar, etc. It can adopt an underground environment with cryogenic temperatures, and the service life could be above 55 years. And the underground rainwater modular tanks are 100% recyclable at the end of lifecycle.
ABOVE 30 TONS/SQM OF LOADING CAPACITY
By the reason of making full use of dynamics and logistic principles, the stability of triangle plays an important role in supporting and balancing. With the combination of round shape, the water storage system is able to provide robust, effective source control through retention, storage and collection at deeper or shallower depths.
HIGH VOID RATIO FROM UP TO 96%
The modular rainwater storage tanks have 96% of void percentage, and it creates a larger subterranean cavity while taking up less space. It results in a reduction in excavation and land clearing requirements. The modular rainwater harvesting system can be configured to provide project-specific storage capacity and help control stormwater runoff.
The names of GS-Tanks according to different purposes
- Stormwater Modules: Modular PP units can form underground storage arrays for stormwater management. Select the model and layout around the project storage volume and structural requirements. For shallow modular build-ups, also see HOENSOEY Cells.
- Modular Rainwater Storage Tanks: A lined and connected tank can store collected rainwater for non-potable reuse, subject to the treatment and water-quality requirements of the intended use.
- Attenuation Tanks: Modules within a suitable lining can temporarily store runoff for controlled discharge. The outlet arrangement and storage volume require hydraulic design.
- Soakaway Crates: Modules used in an infiltration build-up can distribute collected water into suitable surrounding ground. Confirm soil infiltration, groundwater separation and the applicable project requirements.
- Rainwater Harvesting Modules: Modules can be combined with collection, treatment and pumping equipment for non-potable rainwater reuse. Specify the intended use before selecting system components.
- Infiltration Tanks: A modular tank can provide temporary water storage in an infiltration system. Ground conditions, pretreatment and maintenance access determine suitability.
- Underground Rainwater Modular Tanks: The modular format allows storage below ground where surface space is needed for other uses. Review cover depth, access, loading and the complete surface build-up.
Request GS-Tanks Product Information
Send the application, required storage volume, preferred model, quantity and delivery destination. HOENSOEY can review product and supply information for your project or order.
HOENSOEY Cells for Shallow Storage and Drainage
HOENSOEY Cells form the internal honeycomb structure of HCR rectangular modules for shallow storage and drainage layers. Review the complete build-up, water path and project requirements before selection.
Underground Water Tanks for Stormwater Storage and Reuse
Underground water tanks provide space for temporary stormwater storage or rainwater collection. Their role depends on the project: controlled discharge, infiltration into suitable ground, or storage for later non-potable reuse.
For attenuation, stored water is discharged through a designed outlet. For infiltration, the tank must be coordinated with soil and groundwater conditions. Reuse systems also need the treatment, pumping and maintenance arrangements required for their intended use.
The technical specifications on this page list virgin polypropylene or 100% recycled PP. Compare the available structures and dimensions, then confirm the material and declared test data for the selected model.
Placing storage underground can leave the surface available for other uses. The project designer should review excavation, cover depth, loading, maintenance access and the complete surface build-up.
Water storage alone does not establish water quality. Pretreatment, filtration and maintenance requirements depend on the incoming water and intended use. Stored water may be considered for irrigation or other specified non-potable uses within the project design.
Where planted roofs or landscape areas connect to the drainage system, coordinate their discharge with the tank volume and outlet design. Roof loading, waterproofing and planting layers remain separate design requirements.
To review GS-Tanks for a project or supply order, send the application, storage volume, model or available dimensions, quantity and destination. Request the relevant product documents before final selection.
