"German Competences for Sustainable Water Projects“

INWASOL is a German company for the development and realization of sustainable water projects. It was founded in 2009 and belongs to Grasshopper Investments.

Water is a complex issue. Experience has shown that only combined know-how and the involvement of specialised competences from consulting over technologies to long term operation, results in successful water projects. This was the background to form a group of German market leaders, who cover all main aspects in the lifecycle of a water project. The result is a unique concept for “German Competence in Water” as a "One Stop Shop".

In addition INWASOL creates new concepts and innovative business models for water projects. Here our focus lies on decentralized concepts for drinking and sewage water with upscaling potentials. Examples are: container concepts for rural and suburban areas, mobile disinfection services, septic tank management models, water loss reduction methods or franchise models for water entrepreneurs.

As a subsidiary of Grasshopper Investments, which is specialised on private financing for water projects, the horizon of INWASOL comprises always the project side as well as it its implications for the financing side.
