Prof. Dr.-Ing. Stein

Prof. Dr.-Ing. Stein provided essential foundations for a sustained management of drainage systems, as well as for trenchless installations of pipelines and their rehabilitation and maintenance. S & P has its focus on this tradition and its intertwined objectives, as e.g. environmental protection, improved underground supply and disposal infrastructures - and with that an improved quality of life in our cities.

The complexity of this task requires interdisciplinary solutions. Our team of highly qualified professionals at S & P is at your disposal.
Our know-how in planning, construction, operation, maintenance, rehabilitation and management of water supply and disposal networks, as well as the mastery of all trenchless installation methods and pipeline rehabilitation are the key to our success.

In addition to consulting services and practice-oriented solutions we initiate and support a multitude of research and development projects. We advise and assist owners and operators in all fields of rehabilitation and maintenance management of their supply and disposal networks.

Through thousands of successfully realised projects, and in reference books which we published in co-operation with Prof. Dr.-Ing. Stein in English, Japanese and Spanish and which are regarded as standard literature on their field all over the world, it is documented that our opinion counts.

Challenge our achievement potential! For your individual success.
