Residents Fight for Water Supply as Solar Panels Encroach on Algarve Aquifer

A Battle for Resources in Algarve

In the heart of Algarve, specifically in Querença/Silves, a photovoltaic power plant is being constructed over the largest aquifer in the region, raising alarm among local residents. The project spans 96 hectares and involves the installation of 102,399 solar panels in areas designated for maximum infiltration, threatening both the visual landscape and the functionality of the hydraulic network.

Residents of the Quinta da Larga Vista urbanization, which has 146 homes built on plots resembling small farms, have been struggling for public water supply for decades. They currently rely on an artesian well owned by the family of the former property owner and other private sources. Gail Serra, the president of the residents' association, expressed frustration that environmental values are overlooked in favor of large economic interests.

Legal Complications

The urbanization, which was constructed without infrastructure, was later legalized through a revision of the Municipal Master Plan (PDM) approximately three years ago. This change reclassified the area from a National Ecological Reserve (REN) to a rural agglomeration, but residents now bear the burden of finding autonomous solutions for their water supply.

Alexandre Serra, a local agronomist, criticized the municipality for ignoring the impact of the solar plant while neglecting the basic needs of the residents. He questioned how he could obtain permission for a new well when his neighbor, who already has one, refuses to consent.

Environmental Concerns

The Regional Coordination and Development Commission (CCDR-Algarve) has approved the Environmental Impact Assessment for the solar plant, despite the area being classified as REN. The agency stated that there are no water bodies associated with the hydrographic network in the project area, which raises concerns regarding the environmental integrity of this vital aquifer.

Residents fear that the solar installation will create a visual discontinuity in the landscape, with Gail Serra stating, "We will be surrounded by a sea of glass panels." Furthermore, the company providing irrigation water has indicated that they can only guarantee supply until the end of the year.

Luísa Luís, the vice president of the Silves Municipality, acknowledged the legitimacy of the residents' demands but stated that the municipality cannot meet these needs in the short term due to the complexity of the project. She mentioned a commitment with the company to ensure water supply continuity despite the ongoing challenges.
