Cities are often built for cars, concrete, and drainage, but not for nature. Streets, sidewalks, parking lots—these impervious surfaces don’t absorb rain; they funnel it into storm drains, picking up pollution along the way and dumping it into rivers, lakes, and oceans. That’s why the surge of interest in “green infrastructure”—permeable pavements, rain gardens, filter bricks—matters. One promising solution comes from AquiPor Technologies, which has developed upcycled bricks that act like filters, letting water flow through while trapping pollutants. These permeable paver bricks could offer a scalable, sustainable way to reduce urban runoff pollution while reusing materials.
The Problem: Pollution in Stormwater
Stormwater runoff is more than just water after a downpour:
What it picks up: Oil, heavy metals, microplastics, sediments, nutrients, and other pollutants accumulate on paved surfaces. When rain hits, it carries all those into waterways.
Why it’s dangerous: These pollutants degrade water quality, harm aquatic ecosystems, and can even affect drinking water.
Existing infrastructure struggles: Traditional storm drains are built to move water fast, not to filter it. Many urban areas lack sufficient green infrastructure to mitigate pollution effectively.
AquiPor Technologies addresses this gap with a product that combines three major features:
Permeability: Their material lets water percolate through it—less runoff pooling, less pressure on storm drains. Inhabitat+1
Filtration: While letting water through, the bricks filter out debris, dirt, and particle pollutants. Inhabitat+1
Upcycling & material reuse: The bricks are made using upcycled or repurposed materials, which reduces waste and the energy footprint compared to traditional concrete pavers. Inhabitat+1
How the Bricks Work
AquiPor’s bricks are designed like this:
They use a concrete-like mix that’s engineered to be porous enough for water to travel through. Inhabitat
When it rains, instead of water flowing over impervious surfaces, it’s absorbed by these permeable bricks.
As water flows through the brick’s pores, sediment, dirt, and particles are left behind or trapped, resulting in cleaner water that enters the ground or stormwater system.
Because of their upcycled nature, they also divert waste that might otherwise end up in landfills.
Benefits of Pollution-Filtering Bricks
These upcycled permeable bricks offer several environmental, social, and economic benefits:
Improved water quality – Reduced pollutant loads reaching waterways.
Reduced flood risk – Better absorption can reduce peak runoff volumes after storms.
Lower maintenance – Less clogging of drains and fewer costly stormwater infrastructure upgrades.
Sustainable material lifecycle – Using upcycled components reduces embodied energy and carbon.
Beautification and utility – Can be used for plazas, sidewalks, parking areas, bike paths—places that need hard surfaces but want environmental function.
Challenges and Considerations
As promising as the technology is, it doesn’t come without trade-offs:
Clogging risk: Over time, sediments and fine particles can block pores. Maintenance (e.g. periodic cleaning) will be needed.
Durability: Need to ensure the material holds up under freeze-thaw, heavy loads, and wear.
Cost and adoption: Upfront cost may be higher than standard pavers; convincing municipalities or developers to use them requires demonstration of long-term value.
Supply chain of upcycled materials: Scaling up means ensuring a consistent, safe supply of upcycled input materials and quality control.
Use Cases & Real-World Applications
AquiPor has applied or proposed its bricks in several contexts:
Urban sidewalks or plazas, where stormwater runoff is high and impermeable surfaces dominate.
Parking lots or driveways, replacing asphalt patches with permeable brick sections.
Infrastructure projects where green stormwater management is part of regulation or sustainability goals.
Cities with combined sewer systems (that overflow during storms) or places with regulatory pressure to reduce runoff pollution are especially strong candidates for adoption.
Policy & Urban Design Implications
For technology like this to make broad impact, supportive policy and design practices are important:
Stormwater management regulations can require or incentivize permeable surfaces.
Green infrastructure grants or subsidies can offset upfront cost.
Maintenance guidance to ensure performance over time.
Urban planning that integrates these technologies into public spaces from the start, rather than retrofits.
FAQs
Q1: Do the bricks completely eliminate pollution from runoff? Not entirely—but they reduce particle pollution significantly. They work best as part of a system that also includes vegetation, bio-swales, catchment systems, and regular cleaning.
Q2: Will they work in places with heavy traffic or heavy machinery? That depends on load rating and material strength. For light-to-moderate traffic (pedestrian walkways, plazas, sidewalks), yes. For heavy loads (truck traffic, industrial) you’d need spec’d versions or reinforced substrate.
Q3: What about winter climate and freeze-thaw cycles? Porous materials can be vulnerable if pores freeze. Designing for local climate—using suitable materials, drainage below, and protective layers—will help prevent damage.
Q4: How often do they need maintenance? Every few years, or sooner if clogged. Sweeping, sometimes pressure washing or vacuuming, helps maintain permeability.
Conclusion
Stormwater runoff is one of the invisible crises of modern cities—pollution hidden in plain sight. Upcycled, permeable bricks from AquiPor point toward a future where infrastructure doesn’t just manage water, but helps clean it. With thoughtful design, maintenance, and policy support, these filtering bricks could make urban surfaces part of the solution instead of part of the problem. If cities embrace such materials not as novelty, but standard practice, we may finally transform how runoff, water, and pollution interact in the urban landscape.
