𝘼𝘾 🏕️
December 2, 2024, Rio Ota

The area of the springs, on the Ota River, was once a leisure area for the local population, including the local bathing area in the summer. This site remained natural for a long time after the EPAL was installed, but at a certain point, the intensification of agriculture with the use of chemical fertilizers and pesticides, intensive livestock farming, and urban sewage made the flow from upstream a polluting threat to EPAL's water intakes, and EPAL paved several dozen meters of the river course near the site where it is installed with reinforced concrete.

The Ota River has its source in the Montejunto mountain range. It flows through the Ota area and empties into the Alenquer River, which in turn meets the Tagus River near Vila Nova da Rainha. At this point the river is close to the village of the same name, Ota.
