BDL Ltd. – In service of sustainable and affordable water management


BDL Environmental Ltd. is committed to offer its partners personalized, systematic solutions in all aspects of the water industry.

We conduct our activities with special devotion to professionalism and environmental protection in the fields of drinking water purification, wastewater treatment, storm water management and environmental remediation.

We are present from the beginning of solving environmental issues: from the technological and environmental assessment, through the determination of development directions, the preparation of investment concepts and tender plans, classic civil engineering designing, until trial operation.

The engineering and business knowledge and broad experience of our staff and partners, covers the full technical fields related to design (technology, civil engineering, control engineering and automation), and the complex financial and economic knowledge associated with water utility services, investment planning and implementations.

Due to our diverse professional activities, we consider both technical, ecological, and economical aspects, to find the most sustainable alternatives, to support our clients in optimal decision making.

Over the past decades, we have contributed significantly to the development and proteciton of the aquatic environment in Hungary and in the neighboring countries, as well as the improvement and expansion of the Hungarian water utility services.

Our colleagues in the different segments of the water industry possess an outstanding professional and innovative knowledge, which have been known and recognized in many parts of the world. Our CEO, Mr. Károly Kovács is the President of the European Water Association (EWA), the Hungarian Water Cluster and Vice President of the Eurasian ASEM Water Academic Development Committee.

As a member of the Hungarian Water Cluster, with 24 other corporate members, we can rely on the expertise and resources of more than 2000 colleagues

Thanks to our continuous growth, now we are working together with private and public clients, partners, institutions in and outside Europe.




Technical and Economic consultancy


We apply system approach to the problems threatening our waters, and focus on the complexity and comprehensiveness of their management. We not only consider economic aspects, our development solutions take into account the environmental values of the ecosystem, its characteristics, so that we can provide unique, customer -specific solutions.

In accordance with the European requirements we apply in the design process the method of Dynamic Cost Comparison (DCC) developed with our active contribution, in order to prepare well-established professional decisions through applying the economic principles of cost-efficiency and sustainability related to development of waterworks in practice.


The DCC Guidelines provides an efficient way to perform option analysis for the various technical solutions, in order to improve the cost efficiency and sustainability of the water utility developments, as well as to improve the decision-making process.


The DCC method is completely consistent with the domestic and EU legislations and methodological recommendations, its calculation process as well as the presentation of the results is schematic, so the results can be easily understood, it is transparent and straightforward for engineers, economists and policy-makers alike.

Besides economical consultancy, we regularly organize trainings and seminars, we are lecturers in demand at major universities. We deliver presentations at national and international conferences on the best practices of asset management, Life Cycle Costing (LCC) approach and Dynamic Cost Comparison (DCC) to achieve sustainable and professional long term utility management.

We also provide technical evaluation activities; by systematic assessment, we can provide complex suggestions, to improve the effectiveness of existing facilities, and to decrease operational cost and ecological footprint.

BDL provides you sound professional basis to make optimal decisions considering both technological and economic aspects.


Civil engineering:


One of our main activities is classical civil engineering-design and implementation; within that we specialize in the design and implementation of water utilities.

We carry out the planning and development of the networks point-like, plant -like facilities. We furthermore, often participate in the expansion, modification and reconstruction of existing networks and facilities.


Our Projects include the whole range of:

  • Drinking and domestic water purification (extraction, purification and preparation)
  • Municipal and industrial wastewater treatment,
  • Storm water management,
  • Environmental remediation


Full range of engineering, construction and investment preparatory tasks:

  • Technical Condition and Environmental Assessment (eco-audit)
  • Concept design
  • Conceptual authorization
  • Management of licensing processes
  • Preparation of tender documents
  • Detailed design, construction plans
  • Coordination implementation (production, transport , technical supervision)
  • Test operation documentation and supervision (management, remote control and supervision)


With the experience of more than hundred, operating facilities BDL offers you the complete professional design palette.


Utility Asset Evaluation and Reconstruction Planning

The sustainable maintenance of the water utilities is in the context of asset management, and the coverage for this is provided by the depreciation of the assets.

The evaluation of the water utilities is the bases for a predictable operation. The Structured utility asset database, established as a result of the utility asset evaluation process, with this operators, municipalities; utility owners are given an objective view of the value of the utility assets, their real economic and technical state. Based on these the operators and owners are capable of efficient and a sustainable asset management and better operational decision-making.

Developed by our Utility Asset Evaluation department, the multi-faceted, Integrated Utilities Assessment Database ( TIKA ) software received, in 2012, the Eco -Aqua Trade award from the Hungarian Water Utility Association, which counts among its members a 170 water utility provider, several water industrial companies and educational institutions.

Due to our multi-faceted integrated utility asset evaluation methodology, it is possible to create sustainable and responsible bases for asset management and to optimize the utility service tariffs.


Multi-faceted integrated utility assessment levels:

  1. Geodetic survey, creation of utility base maps

  2. Public utility registry, digitizing public utility maps

  3. Identifying, defining Object Groups, establishing the asset inventory

  4. Assessment of Technical Condition

  5. Assessment of depreciation indicators

  6. Calculation of replacement costs

  7. Determination of asset value – utility evaluation

  8. Consultancy with regards to the asset management and water utility tariffs
