Rainwater conservation vs. ecology: Morocco debates water management

As Morocco grapples with water scarcity, a debate is emerging over whether the country should store rainwater that currently drains into the sea or allow it to continue its natural course.

Many Moroccans wonder if urban flooding and wasted rainwater could be mitigated by implementing better collection systems, particularly in the country’s northern coastal cities, which receive the highest rainfall. These discussions coincide with Morocco’s exploration of German rainwater management strategies, aiming to optimize water use in households and adapt to climate change. Pilot programs are set to launch in Tangier and Marrakesh.

Jalal Maher, a civil engineer, argues that urban rainwater drainage is crucial for preventing floods and protecting the environment. “Urban drainage involves collecting, transporting, and managing rainwater in cities,” Maher told Hespress AR. He explained that modern networks of pipes and trenches can channel water into retention basins or natural reservoirs, enhancing water conservation.

He proposed that Moroccan cities adopt plastic drainage pipes with perforations that allow water infiltration while directing excess flow into main collection systems. This, he said, could prevent water loss and ensure better resource management.

However, environmental experts warn that diverting rainwater into reservoirs could disrupt natural ecological processes. Ahmed Talhi, an expert in environmental development, asserts that rainwater reaching the sea plays a vital role in maintaining Morocco’s marine biodiversity.

“Coastal fishing depends directly on rainfall,” Talhi told Hespress AR. “Rainwater carries plant materials and soil deposits to the sea, attracting fish species that feed on these nutrients. This natural cycle sustains marine life and supports the fishing industry.”

Additionally, he cautioned that rainwater flowing through rivers and natural streams helps replenish underground water reserves. “If we confine rainwater in reservoirs, we limit its distribution, potentially depleting essential groundwater sources in other regions,” he said.

As Morocco explores innovative water management solutions, experts emphasize the need for a balanced approach—one that mitigates water waste while preserving environmental equilibrium. The upcoming pilot projects in Tangier and Marrakesh will provide a critical test for integrating rainwater conservation with sustainable ecological practices.
