 Due to temperature changes, the moisture-saturated biogas will form inevitably condensation water in the piping system. Ideally, the piping system should be laid out in a way that allows a free flow of condensation water back into the digester. If depressions in the piping system can not be avoided, one or several water traps have to be installed at the lowest point of the depressions. Inclination should not be less than 1%.

 The piping system connects the biogas plant with the [[Biogas Appliances|gas appliances]]. It has to be safe, economic and should allow the required gas-flow for the specific gas appliance. '''Galvanized steel (G.I.)''' pipes or '''Polyvinyl chloride (PVC) '''pipes are most commonly used for this purpose. Most prominently, the piping system has to be reliably gas-tight during the life-span of the biogas unit. In the past, faulty piping systems were the most frequent reason for gas losses in biogas units.
