Company policy

The management of BHU Umwelttechnik GmbH has decided on the following company policy in order to achieve the corporate goal - long-term securing and expansion of their market position, preservation of jobs, securing and expansion of earnings:


The context refers to the BHU Umwelttechnik GmbH with the operating site Leonberg.

The integrated quality, occupational health and environmental protection management system according to ISO 9001 (QM), ISO 45001 (AM) and ISO 14001 are part of all business processes. The management system meets the requirements of ISO 9001: 2015, ISO 14001: 2015 and ISO 45001: 2018.


The three management systems - QM - HS - EM are implemented as an integrated management system - IMS - in the company policy.


Our business model includes the development, planning, execution, commissioning and maintenance of drinking, industrial and wastewater systems as well as sludge treatment systems on the basis of our own process engineering competence and preferably on the basis of our own and implemented technology.


We are the technological partner of our customers. We understand your requirements and can therefore meet your individual requirements and expectations to the fullest satisfaction.

To ensure the best possible products, we cater to our customers not only technologically, but also culturally. Our quality standards apply equally in Germany and in foreign markets.


Our quality standards include planning and implementing the best possible treatment method for each application; this both in terms of the performance parameters as well as the investment and operating costs.


To complement innovative ideas as well as to comply with changed laws and requirements in good time, we maintain an open and interested cooperation with universities and authorities.

The aim is to maintain and continuously improve the following:


We want to make a contribution to environmental protection with our technologies, in the development of which we attach great importance to sustainability in terms of energy efficiency and resource conservation.

Our products embody reliability and innovation. We set ourselves the goal of producing products that are safe to manufacture, safe to use and, if necessary, to be disposed of safely. We take great care to ensure the safety of operations and work.


We owe our business success to our products, high flexibility, reliability of employees, delivery reliability and, first and foremost, the high quality standard in our company.

We are constantly developing the quality of our work in order to meet the high demands of our customers.



Environmental protection and its improvement is part of our corporate policy. With future-oriented, quality-promoting and environmentally friendly processes, we meet the increasing demands of our customers and the market.

As part of our society, we undertake to preserve our environment and to continuously improve it through our service „construction of state-of-the-art water treatment plants“. We prevent environmental pollution through the professional use of materials and resources. We see it as our task to preserve raw materials and energy from the point of view of resource conservation.

Occupational Safety, Health Security, Plant Safety:

The health of our employees is our most valuable asset that needs to be protected. We are therefore taking all necessary measures to create and maintain secure jobs. The prevention of accidents and occupational diseases with the aim of improving the relevant company standards are the central aspects of our work and health policy.

A high availability of our systems and resources is a goal and a necessary prerequisite for our service.

Servicing, maintenance and regular testing are therefore an integral part of our corporate policy.


We want to meet the requirements of our customers through competent customer advice, flexible reaction to customer requirements and smooth order processing. The primary goal is to fully meet customer requirements and to adapt operations to changing customer requirements, quality criteria and new processes.

By maintaining a close partnership with our customers, we can bring our knowledge and experience to our mutual benefit.


Every employee is responsible for the quality of their work results. We promote and reward in a target-oriented manner all ideas and measures of our employees that bring about quality improvements, occupational safety and a reduction in the environmental impact of our products. Due to the high level of motivation and qualification of our employees, we create the basis for customer-oriented, quality, environmentally and safety-conscious work. The management therefore promotes training and further education for employees.

Continuous improvement / error prevention:

We don‘t want to ensure the quality of our systems by eliminating errors, but rather by avoiding errors at an early stage. Every employee is called upon to actively participate in this process with their own ideas and suggestions. The integrated management system helps us to continuously improve our procedures and processes and to reduce our costs.


We undertake to limit the impact on people and the environment in the planning, manufacture, storage, transport, distribution and use of our systems to the absolute minimum.

We only work with suppliers who are willing to support and support our objectives in a spirit of partnership and without reservation.


We are committed to complying with existing environmental and occupational health and safety laws and regulations. Systems, products, emissions and disposal are monitored independently. What is recognized as necessary is tackled on its own initiative, even without legal obligation or official requirements.

Our partners:

The shareholders provide the company with the financial means and support it with their resources and worldwide connections in achieving the company‘s goals.

We strive to generate an appropriate financial dividend for the shareholders for the financial risks they bear.
