We help our clients make more money

At Onlinewater.io, we choose to focus on just a few clients at a time. This way, we can dedicate the resources it takes to thoroughly understand and grow them to their fullest potential. We help educate, fuel and build long-lasting relationships with the clients we work with.

We work only on environmentally related projects. We are water and wastewater professionals. We have participated in many trade fairs, in the drafting of technical brochures and their translation, and what can we say about the time spent on transportation! Over the years, we realized that it was much more effective to communicate on the web.

Since we made this transition successfully, we thought we should share this new organization. Nicolas Meudal then created Onlinewater.io, a communication agency dedicated to environmental services.

Onlinewater.io: The power of digitization to support sustainable development

In concrete terms, we offer communication and marketing services as well as engineering and consulting solutions.

Regarding digital marketing, our offer ranges from the simple website analysis to the complete website development, but we only deal with topics related to the environment. Indeed, when it comes to writing technical content on a particular technology, it is best to assign this task to someone who understands the industry.

Our industrial background allowed us to understand assembly methods, materials, industrial design. If you need to develop a prototype or produce new water treatment equipment, we can help you!

Finally, thanks to our years’ experience in engineering firms, we can now offer you services such as the drafting of tenders, training on various technologies, or even sales representation.
