Seville City Council has begun the installation of aeration systems in the lakes of the Tamarguillo, Miraflores, and Infanta Elena parks, with an investment of €192,591. The measure aims to improve water quality and prevent algae problems and unpleasant odours.
Seville City Council, through the Parks and Gardens delegation, has initiated the installation of new aeration systems in the water bodies of the Tamarguillo and Miraflores parks, a project that will extend in the coming days to the lake of the Infanta Elena Park. The investment amounts to €192,591.93 and is part of a technical plan to enhance the environmental quality of these green spaces.
The equipment includes aerators, submerged diffusers, weighted pipes, and specific electrical installations, adapted to the characteristics of each lake. The objective is to increase dissolved oxygen levels, promote water circulation, and reduce excess nutrients, which helps prevent the proliferation of algae, turbidity, and unpleasant odours.
A technical solution for recurring problems
The delegate for Parks and Gardens, Evelia Rincón, explained that “this intervention is not an aesthetic or one-off measure, but a technical action to improve the ecological functioning of the lakes and address the root causes of the problems.” Previous equipment lacked the capacity to oxygenate the entire water surface, necessitating a specific intervention.
Rincón emphasised that “the lakes in the parks require continuous maintenance, especially in a city like Seville, where high temperatures directly influence the water's ability to retain oxygen.” The action also includes reducing mowing debris and organic matter that may fall into the water, as well as informational campaigns to prevent citizens from feeding ducks and fish, as these contributions increase nutrient levels.
The Infanta Elena lake poses no risk after reddish discoloration
In the Infanta Elena Park, where a reddish discoloration of the water was detected a few weeks ago, alarming residents, the City Council has reminded that this discoloration is no longer visible and that analyses conducted did not detect any abnormal parameters. The pH, conductivity, iron, and manganese values were within normal ranges, ruling out an episode of contamination.
Periodic inspections have not recorded any mortality of fish, amphibians, or birds in the lake. The technical explanation points to the development of a type of algae at the bottom of the pond, with no impact on the fauna or the environment. “The data does not support a narrative of neglect or environmental risk,” Rincón insisted.
Continuous maintenance for Seville's green heritage
The installation of the aerators is part of a continuous maintenance plan for urban lakes, which includes periodic analyses and inspections. Rincón concluded that “the goal is clear: to care for the parks, protect their biodiversity, and maintain the water bodies that are part of Seville's green heritage in better condition.”
Residents of the city will notice an improvement in water quality and a reduction in potential odours, especially during the hot months. The works have already begun in Tamarguillo and Miraflores and will continue in Infanta Elena in the coming days.
