The ÖBf is responsible for numerous spring and lake regions in Austria and wisely protects drinking water reserves for the coming generations. aqua plus is a competent partner for water supply projects. Starting with the preparation of solution variants, we accompany or independently complete all areas of project implementation such as the planning, financing, construction and operation of water supply projects. We have particularly extensive know-how in fighting water loss and low-excavation piping renovation.
