The filter ponds in Leers were built to supply water to the Roubaix Canal, which is located nearby. Their primary function is to purify some of the water from the Grimonpont wastewater treatment plant. This plant initially filters 75% of the water; the ponds then process the remaining 25%. This final filtration takes seven days. During this process, the water flows through several ponds, moving from one to the other by gravity. This filtration technique is called phytoremediation: the water is naturally purified by algae, plants, and microorganisms that thrive in these ponds. In Leers, plants such as yellow iris and purple loosestrife, among others, play this purifying role. After seven days of filtration, the water flows into a final 9,000 m² basin. At this stage, it is perfectly purified and of very high quality. This final basin, known as the "storage basin," is the final step before the water is conveyed to the canal. The Leers filter ponds, formerly a landfill, are now a peaceful 5-hectare nature reserve, perfect for a relaxing walk, alone or with the family. The area is home to around thirty bird species, including the coot, the Mediterranean gull, and the reed bunting. If you look closely, you might even be lucky enough to spot a smooth newt swimming in the ponds, searching for small invertebrates to feed on. To protect the environment and wildlife, dogs must be kept on a leash on the paths and are not permitted in the winding sections of the ponds. Source: enm.lillemetropole.fr
