Sewer Construction and Rehabilitation

Besides the targeted planning of economical solutions and taking into account all influencing factors, we also design sustainable rehabilitation strategies which we evaluate and choose – together with you – for their technical and economic feasibility.


One of the crucial preconditions for the protection of groundwater is the construction of technically correct, leakproof sewer systems. We offer you the full spectrum of engineering services in regard to sewer system construction. They range from planning to tendering to construction supervision and management-oriented consulting for sewer maintenance.
