TRICEL NERO RANGE - STORMWATER MANAGEMENT
Underground drainage system
OVERVIEW
An underground drainage system comprises pipes, channels, and structures intended to gather and transport surplus water from rainfall, surface runoff, and other origins, diverting it from urban or developed regions.
Its primary function is to mitigate flooding, erosion, and waterlogging by effectively channeling stormwater to suitable outlets such as rivers, lakes, or treatment facilities.
Discover the Tricel Nero Range that contains two solutions: Tricel NeroStor and Tricel Rigofill, and considerations for your project.

Type of Underground drainage system
In this article, we’ll compare two underground drainage systems from the Tricel Nero range.
Nerostor
NeroStor, developed by Tricel, is a modular stormwater storage system featuring high-density polyethylene (HDPE) chambers that interconnect seamlessly to create underground storage structures. This design maximizes storage capacity while minimizing required footprint space.
Key Features of Tricel Nerostor
Modular Design
NeroStor’s modular design offers flexibility to adapt to diverse site requirements. Installers can customize the size and layout of the storage system to meet specific project needs.
High Capacity
These chambers boast substantial stormwater storage capabilities, effectively easing strain on drainage systems during periods of heavy rainfall.
Durability
Crafted from HDPE, NeroStor chambers are corrosion-resistant and engineered to endure the demands of underground installation.
Easy Installation
With comprehensive installation instructions provided, assembling NeroStor chambers on-site is efficient, lowering labor expenses and installation durations.
Rigofill
Rigofill is an innovative stormwater attenuation system that diverges from conventional concrete tanks by employing lightweight plastic modules, which are straightforward to transport and install.
The system is meticulously engineered to enhance water infiltration and optimize storage efficiency.
Key Features of Tricel Rigofill
Lightweight Construction
Rigofill modules are crafted from lightweight plastic, facilitating easy handling and transportation to installation sites. This feature simplifies logistics and reduces installation time.
Infiltration Capability
The design of Rigofill encourages water infiltration into the surrounding soil, supporting groundwater replenishment and mitigating surface runoff.
Versatility
Rigofill modules offer flexibility in layout configurations to meet specific site requirements, optimizing space utilization effectively.
Environmental Benefits
By promoting infiltration and groundwater recharge, Rigofill contributes to maintaining natural hydrological cycles and fostering sustainable urban development practices.
Main differences between these 2 Underground drainage system
1. Material: Nerostor utilizes HDPE chambers known for their durability and corrosion resistance. In contrast, Rigofill modules are crafted from lightweight plastic, offering similar robustness and resistance qualities.
2. Installation: Both systems feature straightforward installation processes. Nerostor’s modular design provides flexibility to adapt to various site constraints effectively.
3. Storage Capacity: Both systems offer substantial storage capacity for stormwater management. Nerostor’s modular chambers are designed to optimize storage efficiency, potentially offering a more efficient use of space compared to Rigofill modules.
4. Infiltration: Rigofill is specifically engineered to enhance water infiltration into the surrounding soil, making it ideal for projects focused on groundwater recharge and sustainable drainage solutions.
What system to choose for what project ?
Objective:
Tricel Rigofill aims to mitigate floods and manage stormwater volume by temporarily storing runoff. Tricel Nerostor systems focus on promoting infiltration and groundwater recharge by facilitating the absorption of stormwater into the ground.
Components:
Attenuation systems like Rigofill typically include storage tanks or basins with controlled outlets. Soakaway systems such as Nerostor consist of underground structures filled with permeable materials to enhance infiltration.
Application:
Attenuation systems are ideal for urban areas with limited space for surface detention ponds. Soakaway systems are suitable for locations with well-draining soils and where promoting groundwater recharge is beneficial.

Frequently Asked Questions
Why do you need attenuation ?
Attenuation offers a lasting remedy for mitigating the risk of flooding resulting from water runoff during extended periods of rainfall. These systems incorporate a flow control chamber designed to regulate the volume of water discharged into a nearby sewer system or watercourse, such as a river or reservoir.
How close can stormwater attenuation be to a building?
Unlike a soakaway system, underground floodways can be positioned much closer to a building. The critical consideration is ensuring that the building load or foundation load does not impact the tank. Ideally, if you were to draw a 45-degree angle from the foundation, that line should not intersect the tank. However, this may vary depending on the depth of the tank. Nonetheless, they can be situated in proximity to the building.
What are critical factors to consider with stormwater?
The main factors to check out to choose the best system for your project are :

How do flood tunnels work ?
How does attenuation work?
Attenuation serves as a straightforward system for storing excess water, receiving water from various inlets like pipes and channel drains while typically having a single outlet. Acting as a void, the tank allows water to accumulate, preventing downstream drains from becoming overwhelmed during heavy storms. The outlet usually incorporates a flow control device, such as an orifice plate or vortex flow control, to regulate the discharge rate of water. Tank size is determined based on factors such as rainfall, surface area, and considerations for climate change.
Properly designed tanks should consistently accommodate the site’s water volume.
