Product Overview
As a direct manufacturer, BDB Metal offers the 3,500-litre underground waste container with all the structural advantages of the 5,000L model in a more compact volume. Engineered for small-population districts, narrow axes, residential complexes and mid-scale commercial sites, this capacity neither over-provisions space nor falls short of demand. Smaller excavation area, shorter installation time, lower overall project cost. The 3500L buried waste container system is the optimum solution for those seeking the right-sized investment.

3500L Underground Waste Container — Product Features
Material Structure
Concrete Block: Fixed concrete body in standard dimensions (1,980 mm × 2,180 mm, depth 1,550 mm); resistant to ground pressure and moisture conditions.
Metal Components: Manufactured with galvanised sheet, painted sheet and hot-dip galvanising options. Waste chute available in stainless steel on request.
Inner Body: Side walls in galvanised sheet steel; bottom covers in hot-dip galvanised steel.
Mechanical & Functional Features
- Pedal system on the waste chute is standard. Full integration with Kinshofer (Double Mushroom), Double Hook and F90 lifting attachments; compliant with EN 13071-3 standard.
- Fully buried structure isolates odour and liquid leakage from the surface.
- 3,500L capacity significantly reduces collection frequency compared to conventional surface systems.
- Waste chute closes slowly and automatically via spring and gas-damper system; prevents animal entry, wind effect and vandalism.
- Silent, leak-proof operating mechanism.
- Simple and minimal surface design compatible with urban aesthetics.
Performance
- Equivalent storage capacity to 4–5 × 770L conventional surface containers.
- Efficient waste management for medium-density areas without over-sizing.
- Smaller installation area, faster setup, shorter downtime.
- Measurable savings in fuel consumption and personnel routing costs.
- Buried structure eliminates visual pollution entirely.
Collect waste with a volume of 3500L, more efficiently than the 770L standard waste container.
Hide bad odors underground with underground structure
Ensure longer service life with its corrosion-free structure.
Save both staff and time by collecting high volumes of waste.
Get rid of the problem of your standard 770L waste container products not fitting inside the container
Add value and longevity to your work by choosing quality materials.
Choosing the Right Capacity: Why 3,500L?
For historic neighbourhoods with narrow streets, mid-sized residential complexes or sites with limited excavation depth, the 5,000L system can sometimes be oversized. This is where the 3,500L municipal underground waste container steps in: it consolidates the capacity equivalent of 4–5 standard surface containers at a single point, with a smaller excavation area and lower infrastructure cost.
For municipalities, this means the ability to install containers at more locations within the same budget. For site managers, it is both an aesthetic and practical solution: an invisible, odour-free, low-maintenance waste system.
Compact Installation, Full Protection
The concrete body withstands ground pressure and moisture conditions. Galvanised steel components do not rust and resist chemical corrosion. The waste chute closes slowly and automatically via spring and gas-damper system, preventing animals, wind and deliberate interference.
Despite its compact dimensions, the system operates as fully buried as larger-capacity models: no odour reaches the surface, no liquid seeps through, the surroundings remain clean.
Areas of Use
- Small and mid-sized municipalities: Narrow streets and districts, squares and parks.
- Residential complexes and social housing projects: A solution that preserves aesthetic integrity and operates quietly.
- Tourist areas and holiday resorts: Invisible system suitable for high seasonal use.
- School and university campuses: Management of high but controlled waste generation.
- Small commercial areas and bazaars: The ideal transition model for those who find the 5,000L excessive but wish to move away from surface systems.
Separate models for glass, plastic, paper-cardboard and organic waste can be manufactured on a project basis.
Logistics Savings
If 4–5 × 770L waste containers were to be collected at the same point, the vehicle would make 4–5 stops, the lift-and-empty cycle would be repeated each time, and fuel, time and personnel would be spent on every occasion. With the 3,500L underground waste system, the entire process is reduced to a single emptying. For municipalities with intensive route planning, this difference translates into dozens of hours and significant budget savings over a season.
Future-Ready Infrastructure
Municipalities do not need to change their existing fleet for 3,500L underground waste containers. A mixed network can be established: the high-capacity 5,000L underground waste container for high-density points, the 3,500L for medium-density points. Both are emptied with the same crane, the same driver, on the same route. This flexibility carries the infrastructure investment into the future.
