About us

International Holding with presence worldwide


DimWater Engineering, belonging to Dimasa Grupo, directs its activity to the development and application of technologies for the treatment of residual effluents (water, biogas and leachate).

In 1986 Plásticos y Poliéster Dimasa was founded with the aim of manufacturing polyester components for the industrial sector.

The constancy for the preservation of the environment of the founders and the new incorporations for more than two decades, facilitated the creation of DimWater Engineering, to cover the market of treatments for Water, Biogas and Waste, process optimization and energy recovery.

The commitment to the pursuit of excellence and the professionalism of our team has allowed us to design a leachate treatment process and a state-of-the-art biogas cleaning process that reduce the customer’s operating costs.

We carry out all the projects under the concept “turnkey”: feasibility study, engineering and design, manufacturing, delivery, commissioning and after-sales maintenance.


Our production plant, with an extension of 5,000 m2 and a team of 40 operators, is equipped with high technology for the production of our equipment, complying with the highest quality requirements and current regulations, such as the ISO System Certificates Quality Management (ISO 9001) and Environmental Management System (ISO 14001). We also have our own fleet of vehicles, which allows us to be more agile and competitive in our logistics department.

In addition, the business group is also formed by Plásticos y Poliéster Dimasa (responsible for the manufacture of equipment and tanks in polyester reinforced with fiberglass / GRP) and Dimamex (a subsidiary in Mexico to nourish the Latin American market).
