The Park of the Rieres d'Horta was inaugurated in summer 2013 on the cover of the rainwater regulation tank and the Park for cleaning the road cleaning services of the Horta-Guinardó district. Down there the torrents of Collserola and below, formed the old Riera d'Horta, the most important watercourse of the hydrographic system of the Plan of Barcelona. The Park incorporates energy self-sufficiency and renaturation. It has Mediterranean vegetation adapted to climatic conditions with areas of shade in summer and sun in winter.
The name was chosen by the neighborhood. The proximity to Collserola makes it a connector of biodiversity between the mountains and the city.
About renaturalization the planting of natural bearing trees allows obtaining high biomass density and enhancing the connection with Collserola. Regarding energy self-sufficiency, it has a 642 m2 photovoltaic pergola and public lighting via telemanaged LED according to demand.
Below is a municipal stormwater reservoir.

Landscaping and design
An accessible path runs longitudinally through the park. On the 1st terrace is the photovoltaic pergola that shades the bowling and petanque courts and has a bar and public services. The lighting consists of 921 LEDs embedded in the walls. On the 2nd terrace there is a health and sports circuit aimed at the elderly. The 3rd terrace houses the accessible children's play area. The last terrace has a central space of compacted earth, pavement areas and bleachers, and a wooded setting for neighborhood events. The distribution of trees creates areas of shade in summer and sun in winter. The rainwater is used for irrigation and the sun's energy for lighting.

Water Games Fountain
Water projection system with 16 springs of vertical water jets and water mist on the pavement and illuminated with LEDs that combine red, blue and green and an interactive game with push buttons.
The source has a recirculation, filtering and sterilization system by ultraviolet light or aeration. It also has an anemometer to control the height of the jets depending on the wind speed.
