Preserving our environment
Economy and ecology: the main challenges of industrial effluent treatment and wastewater treatment. Every day, they are the driving forces behind life and progress. We need to be aware of them. Understanding the balance is the key to understanding our work.
“Let’s act, protect and be environmental firefighters! ”
Julien Blanvillain, Director of SEMEO

Towards a responsible economy
The aim of wastewater reclamation is to reduce the volume of effluent. In concrete terms, SEMEO aims to reduce effluent by a factor of 4 to 10, depending on the type of sludge to be dewatered or wastewater to be treated.
Ensuring that the state of waste is just one stage in a process of optimizing resources to achieve real benefits for all. The challenge, therefore, is to ensure that expenditure is well-judged in order to generate added value and a significant return, thereby enabling the green economy to drive growth.

Towards an ecological balance
SEMEO’s core business is based on the intelligent management of resources and the provision of ecological sanitation that preserves the environmental balance.
This responsibility for the future is SEMEO’s mission to serve the common good. That’s why we’ve developed our ecological mobile solutions based on a rigorous working protocol. The challenge is to create an economy that nurtures and respects the environment. That’s the balance of the issues that motivate and engage us.
Committed to the common good
High standards and trust are essential to establish a healthy and lasting professional relationship. That’s why SEMEO has created a charter of commitments to help you build a lasting partnership in the management of your effluents.
Article 1 : Our first commitment is to results. Control, advice, water and sludge treatment using mobile units: at every stage of the action plan, SEMEO works to guarantee you the desired result.
Article 2: Committing to you means putting the discipline of our work at your service. SEMEO listens to you in order to understand your challenges and meet them throughout the collaboration through our customer support service.
Article 3: The environment and the economy are demanding, complex and ever-changing fields. SEMEO is committed to constantly evolving and developing its skills to best meet global demand.
Article 4: The challenges and work of the company are based on the well-being of the men and women who make it up. This is why SEMEO is committed to guaranteeing the best possible working conditions for all employees involved in wastewater treatment or sludge dewatering using mobile equipment.
Article 5: Finally, SEMEO undertakes to use all available means on the sites to limit the impact of our business on the economy and the environment.
