The Hidden Peril of Open Stormwater Drains

A silent, overlooked menace lurking beneath Monrovia's streets

Not as harmless as they look. Open stormwater drains crisscross Monrovia's roads, touted as easy to maintain — a claim this report puts to the test.

In the bustling streets of Monrovia, a silent and often overlooked menace lurks beneath our feet. Open stormwater drains, those seemingly innocuous channels carved into the urban landscape, pose a significant threat to pedestrian and cyclist safety. While they may appear as convenient water conduits and are touted as easy to clean, the reality paints a starkly different picture.

In this article, we delve into the statistics and dangers associated with open stormwater drains, presenting the current condition of open channels, drains, and sewer lines in Monrovia — and examine the notion that they are a straightforward, easy-to-maintain flood control measure for cities.

A looming menace

Three ways open drains endanger road users

  • Accidental falls Thousands injured each year from slips, trips, and falls
  • Cyclist mishaps Riders lose control and sustain severe injuries colliding with drains
  • Fatal encounters Pedestrians and cyclists have lost their lives in open drains

The myth of easy maintenance, debunked

Proponents of open stormwater drains often argue that they are straightforward to clean and maintain. However, this assertion ignores critical issues. Developing countries often lack the necessary resources, both financial and human, to maintain open drains effectively — drainage systems require continuous monitoring and cleaning, which is frequently neglected due to budget constraints.

Cleaning open drains often involves the use of harmful chemicals to dislodge debris and unclog pipes. These chemicals can seep into the environment, polluting water bodies and affecting local ecosystems. Cleaning is itself a hazardous task: the need for manual labor to access narrow channels increases the risk of accidents among maintenance workers.

Beyond the immediate safety concern

Beyond the immediate safety concerns, open stormwater drains have broader environmental and safety disadvantages. Debris, chemicals, and waste often find their way into open drains, contaminating the water supply and posing severe health risks to communities relying on these water sources. Stagnant water becomes a breeding ground for disease-carrying mosquitoes and other pests, increasing the prevalence of vector-borne illnesses. And beyond health, open drains diminish the aesthetics of urban areas, potentially impacting tourism and property values.

A safer path forward

To address the grave issue of open stormwater drains as road safety hazards, we must consider innovative solutions: infrastructure upgrades such as covering open drains with secure grates or replacing them with underground drainage systems; public awareness among pedestrians and cyclists about the dangers of open drains; regular, consistent maintenance of drainage systems; community engagement to foster a sense of ownership and responsibility; and government commitment to prioritize pedestrian and cyclist safety with the resources to match.

In conclusion, the seemingly benign open stormwater drains that crisscross the roads of developing countries hide a significant road safety hazard. Statistics reveal a grim reality of accidents and fatalities, while the notion of easy maintenance is debunked by resource constraints and environmental repercussions. To truly prioritize pedestrian safety and environmental sustainability, developing countries must invest in improved infrastructure, awareness campaigns, and robust maintenance practices. It is only through collective action that we can transform these perilous pathways into safe, thriving urban landscapes.

What it will take

Covered drains, consistent maintenance, and government investment matched to the scale of the risk open channels pose every day.
