What if Morocco stores the rain water that is lost in sewage channels and poured into the sea? A question that many Moroccans ask when watching a threshold of rain is heading directly towards the sea, especially in the coastal cities in the north of the country, which usually lead the most rainy areas in the country.
These questions come in conjunction with the start of talking in Morocco about benefiting from the German experience in managing its water and home use, within the framework of preparing and preparing residential buildings to deal in a strong way with water resources and the rationalization of their consumption to adapt to climate changes, as it is expected that the process of experimenting with Tangier and Marrakech is expected to start.
In this context, Jalal Maher, a civil engineer, considered that “urban drainage is an essential system for rainwater management and treatment in urban areas,” stressing that “with increasing urbanization it is necessary to understand how this process works to prevent floods and protect the environment.”
Maher added, in an interview with Hespress, that “urban drainage includes the collection, transportation and management of rain water in cities,” and added: “Thanks to a network of tubes and trenches, water is directed towards retention ponds or towards natural waterways.”
The same spokesman scored that “the main goal of urban drainage is to prevent and reduce floods and improve the quality of water”, stating that “this process depends on several elements, such as storms, control barriers, tenth dams and retaining areas; It is possible to rely on the drainage of rain water through natural trenches and sinks with armed cement in several geometric forms, including covered and open.
The same engineer pointed out that “in Moroccan cities, it is possible to rely on the distribution of a plastic pipeline network that differs from one from the other according to the importance of the sites; And the characteristic of these pipes is that they have separate holes in their upper hemispheres, which are fixed above with stones that allow water to flow only and direct them to major drains and then to assembly, with the aim of preventing their loss.
But this offering finds those who oppose it, and considers that “the flow of rain water in valleys and watering and its reaching the sea has many gains, and supports the preservation of environmental and ecosystem balances for the country, as well as it enhances and enriches the waterbed.”
Ahmed Al -Talhi, an expert in the environment and development, said that “there are those who see that the water is lost in the sea,” stressing that “it is natural that the rain and snow are not mobilized in dams, whether major or medium or even the tables.”
Al -Talhi added, in a statement to Hespress, that “the water that goes to the sea is useful in enriching the coastal fish wealth,” highlighting that “coastal fishing activity has a direct relationship with rain, when it is good rains, coastal hunting is active, which is the basis for us in Morocco.”
The spokesman added, explaining that “the rain does not carry water with it only, when it takes place the remains of plants and dust to the beaches, and thus contribute to attracting types of fish that live and feed on these loads,” considering that this issue is necessary to enrich the coast and its fish wealth.
Al -Talhi also pointed out that “the flow of rain water in the sewers and watercress makes it contribute to feeding the groundwater mattress; And if we mobilize it, we will limit it to a specific geographical area, and it will not spread and include all lands, which leads to the lack of a group of water brushes of the necessary resources, as he put it.
