Due to intense usage, wastewa-ter systems age rapidly making regular renovation and restora-tion particularly important.

We provide you with options and alternatives for future systems and integrative concepts, tak-ing into account the legislative requirements as well as opera-tional safety and efficiency. Our specialists from various techni-cal fields plan, coordinate and supervise repairs, restoration and renewal of urban drainage systems.C

EBy optimising the operation of sewer systems and their special structures, negative environmental effects, such as storm water overflow, can be minimised and the perfor-mance of the whole system improved.

We analyse the dynamics of wastewater systems in rela-tion to seasonal and regional discharge variations and run models to provide complete solutions for optimised pollu-tion load management relative to the receiving water bodies. We design and coordinate the installation of all automa-tion and control systems and optimise existing systems.

To sustainably protect our water resources, society needs new alter-natives. Our interdisciplinary teams collaborate with clients to develop progressive, appropriate and unique solutions.

BREAKING NEW GROUND

Urban drainage influences the natural water cycle. The Gen-eral Drainage Master Plan is an optimal instrument for water quality protection. With the General Drainage Master Plan we can ensure that water bodies remain clean, now and in future, through structural interventions and sustainable planning.

Using the latest techniques, we advise on all aspects of drainage, determine the actual state and develop and optimise targets for drainage areas.

Municipalities and wastewater associations need to ensure that the financial resources required for capital costs as well as the operation and maintenance of plants and drainage systems are guaranteed.

Using asset accounting and financial models, we determine the cost covering ratios for wastewater management. Our experts help you plan invest-ments and advise on tariffs and policies that will give you a sus-tainable financial and regulatory framework.

NSCareful planning of sewer

construction and the develop-ment of optimum solutions for special structures can add tremendous value to public water networks. We develop comprehensive solutions and identify possible operational alternatives for our clients.

Specialised teams plan and verify all the measures using state-of-the-art applications and methods, to ensure flaw-less project implementation.

ES In wastewater systems, hydrau-

lics are an important factor. We apply static or hydrodynamic calculation methods as required. Long-term performance of sewer overflows and rainwater basins are investigated with numeric simulation models that take into account perennial precipitation data.

Our experienced staff are also involved in national research and development projects.
