Los viajes del agua (II)

- Recreational infrastructure for rainwater collection, treatment and visibility -

The Añorga quarry in San Sebastian is located within a territory where water and hydraulic infrastructures have played a determining role in the definition of the site.
However, these architectures are often invisible and remain alien to the pulse of people and the physical context. Valuing as an opportunity the high rainfall in the quarry as well as its topographical condition - a large impermeable surface where the water flows -, a large recreational infrastructure is proposed.

It collects, treats and uses this rainwater understanding the potential that the infrastructures and the water itself have as the germ of programmes and spaces.
The intervention reactivates the quarry with water as the protagonists, where with its different qualities, qualities and speeds, it runs through permeable and hydrophilic architectures that make it visible together with its processes.

3. Rainwater treatment, the visible process

The architecture becomes trasnsparent to water in order to make the treatment processes visible.
From the traces of the necessary infrastructure the circulations arise; ramps, stairs and helicoids that go along with the transparent conduits, allowing to see the water continuously flowing

The water collector roof

A catenary surface forms the roof that acquires its shape by the action of gravity and the weight of rainwater that flows through when it rains.
