Project Ndiyan — Coastal Infrastructure, Engineered
Resilient drainage for African urban futures.
We engineer coastal drainage infrastructure and real-time flood telemetry so that a season of rain never again becomes a city's emergency.
The Problem
Open canals were never built for this much water — or this much waste.
Across coastal West Africa, seasonal monsoonal rains move through drainage networks designed decades ago. When unmanaged municipal waste collects at the chokepoints, ordinary weather turns into flash flooding — displacing families, shutting down commerce, and overwhelming municipal budgets year after year.
Aging Networks
Open-canal systems built for an earlier era of rainfall now run undersized for today's monsoon intensity.
Debris Chokepoints
Unmanaged waste collects at drainage bottlenecks, converting manageable rainfall into standing floodwater.
Seasonal Surge
Monsoon season concentrates a year's worth of stormwater into weeks, straining systems with no buffer.
Human & Economic Cost
Flash flooding displaces residents, halts commerce, and forces cities into reactive, costly emergency spending.
The Technology
An industry-first trash trap, engineered at 45 degrees.
Our hydrodynamic trash-trap systems sit at a 45-degree angle across the canal channel, using the natural force of stormwater flow to lift debris clear of the waterway automatically — no manual clearing crews, no seasonal shutdowns. Paired with ultrasonic water-level sensors and flow-velocity meters, every unit reports live conditions back to municipal operators before a bottleneck ever forms.

Live TelemetryPassive Lift
The 45-degree angle uses channel flow itself to carry debris up and out — no electricity, no moving parts to fail during a storm.
Ultrasonic Water-Level Sensing
Continuous, non-contact measurement of canal water level, streamed to municipal operators in real time.
Flow Velocity Metering
Live velocity data flags emerging bottlenecks long before a blockage becomes a flood.
Global Impact & Traction
A decade of regional flood research, headed toward deployment.
Phase — Research Foundation
Over a decade of regional flood and hydrology research underpins every design decision behind the trap and telemetry system.
Phase — Pilot Delegation
This December, our team travels to West Africa to advance our pilot delegation and deepen municipal partnerships on the ground.
Phase — Municipal Deployment
Our data-driven approach is built to scale from pilot canals to citywide drainage networks across coastal West Africa.
