According to the proposal signed by the councilman responsible for Environment, Green Structure, Climate and Energy, José Sá Fernandes (elected from the Socialist Party lists) and which will be discussed at the private meeting of the municipal executive, the protocol to be celebrated with EPAL - Empresa Portuguesa das Águas Livres, establishes the terms of collaboration in five points, including the rehabilitation of several fountains in the city.

The first fountains that EPAL undertakes to rehabilitate, still in 2019, are the Garridas or Benfica fountain (in the parish of Benfica) and the Intendente or Desterro fountain (in the parish of Santa Maria Maior).

In 2019/2020, conservation and restoration interventions are planned in the fountains of Janelas Verdes, Mãe d'Água à Praça da Alegria, Rato, Carmo and Santo António da Convalescença.

Between next year and 2022, EPAL will also carry out conservation and restoration work in eleven more fountains in the city.

According to the protocol, after the interventions, the Lisbon city hall will ensure the maintenance and periodic cleaning of the fountains, as well as the surrounding public space.

The document to be signed between the municipality and the company also foresees the widening of the opening to the public of the underground galleries of the city's aqueducts, as well as the opening to the public of the Casa do Arco Garden, authorising the creation of a connection to the gardens of the Maria Ulrick Foundation (Casa de Veva de Lima).

By December 2021, EPAL is also committed to installing 200 drinking fountains in the city.

The proposal presented by Councillor José Sá Fernandes said that Lisbon was distinguished last year with the "European Green Capital 2020" award.

The document mentioned that, during the next year, EPAL will install photovoltaic panels for the electricity supply of the water distribution network of the city of Lisbon.
