El Rosario Residents Raise Alarm Over Construction Waste Discharged Into Sea
Residents in El Rosario, Tenerife, are demanding an official investigation into allegations that a construction site is illegally pumping untreated, sediment-heavy wastewater directly into the sea.
Waste management at a construction site in El Rosario, Tenerife, has sparked a new public debate. Residents have raised concerns that water from the local swimming pool renovation is being pumped directly into the sea, which would violate environmental protection rules for bathing areas.
Local residents documented the process, capturing photos of pumping systems moving liquid from the construction site to the coastline. They claim the water is filled with sediment, cement residue, and sludge from drilling and building work. Neighbors are worried that these pollutants are damaging water quality and the local seabed, noting that there appear to be no filtration or settling systems in place to clean the water before it reaches the ocean.
This situation has put the oversight of coastal projects under the spotlight. Environmental regulations require that any work near the coast must include strict measures to protect the ecosystem. Residents are now calling on the El Rosario City Council to confirm whether this drainage method was authorized and if the project’s supervisors approved the way the liquid waste is being handled.
Because the site is a popular spot for swimmers, the incident has drawn criticism regarding the gap between the council’s sustainability policies and the reality of their construction projects. While residents have provided photographic evidence, there has been no official chemical analysis to confirm the exact contents of the discharge, nor has the council issued a statement on whether any environmental rules were broken. Residents are now demanding a formal technical inspection to ensure the site is following environmental laws and to hold any responsible parties accountable for potential negligence.
