The small volume of the valve chamber of a water catchment area is determined by technical needs;it is about studying its outdoor envelope. This prism is located between two cylindrical tanks; the first one is already built, but it will take 25 years to need the second one. Asuming the long term situation two asymetric dihedral are proposed.

Drinking Water Treatment Station | ETAP Orense consists of several buildings with different volume and organization derived from water treatment process that must be an invariant in the project.
With this starting point, the role of the job is to study and propose the corresponding envelopes also preset materials and the holes needed for pre-configured volumes.

The goal is to achieve the scale, proportion and desired color balance in each building
