Company policy

The management of BHU Umwelttechnik GmbH has adopted the following company policy in order to achieve its corporate objective of securing and expanding its market position in the long term, maintaining jobs, safeguarding and expanding income.


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

The integrated quality, health and safety, and environmental management system ISO 9001 (QM), BS OHSAS 18001 (HS) and ISO 14001 (EM) are part of all business processes. The management system meets the requirements of ISO 9001: 2015, ISO 14001: 2015 and OHSAS 18001: 2007.


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


Our business model includes Development, Project and Contract Engineering, Installation, Commissioning and Maintenance for drinking, processwater and waste water and sludge treatment plants based on our own process engineering competence and preferably based on our own and implemented technology.

We are the technological partner of our customers. We understand their needs and can fulfil their individual requirements and expectations to the fullest satisfaction.

To ensure the best possible products, we are not only technologically, but also culturally responsive to our customers. Our quality standard applies equally to domestic and foreign markets.

Our quality standard includes planning and implementing the best possible treatment procedure for every application; this applies to the performance parameters as well as to the investment and operating expenses.

To complement innovative ideas as well as the timely observance of changed laws and requirements, we maintain an open and interested cooperation with universities and authorities.

The goal is to sustain and continually improve:


We want to contribute to environmental protection with our technologies, whose development 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, safe to dispose of. We take the greatest care in the safety of operation and work.


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

We constantly develop the quality of our work to meet the high demands of our customers.


Environmental protection and its improvement are part of our corporate policy. Through forward-looking, quality-enhancing and environmentally friendly processes, we meet the increasing demands of our customers and the market.

As part of our company, we are committed to preserving our environment and constantly improving it through our state-of-the-art construction of water treatment plants. We prevent environmental pollution by professional use of materials and resources.

We see it as our task to conserve 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, which must be protected. Therefore, we take all necessary measures to create and maintain secure jobs. The prevention of accidents and occupational diseases with the aim of improving the related company standards are the key aspects of our occupational health policy.

A high availability of our plants and resources is a goal and a necessary condition of our service. Maintenance, servicing and regular testing are therefore an integral part of our corporate policy.


Through expert advice to costumers, flexible response to customer requirements and our smoothly-run order processing, we want to meet the needs of our customers. The ultimate goal is to fully meet customer requirements and to adapt the operation to changing customer demands, quality criteria and new procedures.

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


Each employee is responsible for the quality of his work results. We promote and reward all ideas and measures of our employees which lead to quality improvements, occupational safety and reduction of the environmental impact of our products. Due to the high motivation and qualification of our employees, we create the basis for customer-oriented, quality, environmental and safety-conscious work. The management therefore supports the education and training of employees.

Continuous improvement / error prevention:

We do not want to ensure the quality of our systems by troubleshooting, but rather by early error prevention. Every employee is called upon to actively participate in this process with their own ideas and suggestions. The Integrated Management System serves the continually improvement of our processes and procedures and the reduction of our expenses.


We commit ourselves to limit the burden of man and the environment to the inevitable in the planning, production, storage, transport, distribution and use of our facilities.

We only work with suppliers who are willing to support and share our objectives in a spirit of partnership and unconditionally.


We are committed to compliance with existing environmental and occupational safety laws and regulations. Systems, products, emissions and disposal are monitored on their own responsibility. Anything that is recognized as necessary is tackled of its own accord without any legal obligation or regulatory 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 seek to provide shareholders with a fair financial dividend for the financial risks they bear.
