Turn-key Projects

Engineering and construction

Based on the knowledge of the customer’s needs, we suggest an optimized global solution, which connects our scope of supply with the services required by the customer.

Design and construction of water treatment facilities

CIM Aigua offers specific solutions for water treatment both in terms of purification and process water

We focus on the customer’s needs and ensure that all facilities meet the agreed objectives and current regulations.

We are involved in all stages of the project


Preliminary design and/or engineering studies


Supply and installation of equipment, and/or assembly 




Technical service to manage the facilities, to improve the existing systems or for maintenance,

Specific solutions

Process water
