WO 94/19288 PCT/CH94/00029 Abstract In drainage systems in buildings and excavations there is waste and ground water with a high dissolved material con- tent. These mainly inorganic substances often cause the build-up of hard deposits in the water conveying parts of the drainage systems, e.g. waste water pipes. These depo- sits reduce the drainage cross section of the drainage sy- stems thus preventing the water from flowing freely and thus causing back-ups which can result in considerable da- mage. The current processes fo removing these deposits are electro-mechanical cleaning and high-pressure rinsing or abrading with water. These processes are laborious, expen- sive and cause interruptions in operation. It is the aim of the invention to prevent the formation of such depo- sits. To this end, a conditioning agent in aqueous form is added via a metering installation at one or more points in the drainage system. The conditioning agent is mixed with the water arriving at the next channel and prevents the dissolved substances from separating out and causing depo- sits.
