The only fully scientific solution to waterless urinals
Our technology is backed by science — not just engineering. While other solutions rely on mechanical methods or partial water reduction, Smarti’s eliminates flushing completely without compromising on hygiene. Our patented enzyme-based system actively prevents odours, blockages, and bacteria buildup — all without a single drop of water.
Test our technology for yourself.
It’s proven to perform
What the science says
Smarti was developed in collaboration with academic partners and tested under real-world conditions — to create a system that doesn’t just save water, but also performs better than flushing systems on hygiene and maintenance.
Proven to be more hygienic than flushing urinals
Two key studies from academia
1. Virus transmission from urinals
This study found that standard flushing urinals spread viral particles up to 60 inches from the bowl through aerosolised droplets — a major hygiene risk.
2. Aerosol infection transmission in flushing urinals
Found flushing systems rapidly increase airborne bacteria and virus spread.
Why do traditional flushing urinals fail?
But what about maintenance?
Uric acid crystallisation
-
Uric acid: Urine contains uric acid, which can crystallise and form solid deposits.
Incomplete dissolution: While water helps to flush away urine, it may not completely dissolve all uric acid crystals, especially in low-flow systems.
-
pH levels: When urine mixes with water, the pH levels can lead to the precipitation of uric acid crystals.
Crystal formation: Over time, these crystals adhere to the pipe walls and accumulate, forming larger deposits that can restrict flow.
Biofilm formation
-
Organic Matter: Urine provides nutrients that support the growth of bacteria.
Biofilms: Bacteria can form biofilms, which are slimy layers that adhere to pipe surfaces.
-
Reduced pipe diameter: Biofilms can grow and thicken over time, reducing the effective diameter of the pipes.
Increased friction: The presence of biofilms increases friction, slowing down water flow and contributing to further buildup.
Mineral deposits
-
Mineral content: Water, particularly hard water, contains minerals like calcium and magnesium.
Scale formation: These minerals can precipitate out of the water and form scale deposits on pipe walls.
-
Combined effects: When combined with uric acid crystals and biofilms, mineral deposits can exacerbate blockages and buildup.
Reduced flow: The combination of these factors can significantly reduce water flow and increase the risk of blockages.
Specific issues in low flow systems
- Insufficient water volume: Low flow systems use less water, which may not be enough to adequately flush away all urine and dissolved substances.
- Slower flow rates: The reduced flow rate means that residues have more time to settle and adhere to pipe surfaces, increasing the likelihood of buildup.
