Abstract
An arrangement is provided in a drain water system having a main drain conduit which is designed as a closed ring conduit (19), and pump members (17, 18) are arranged to pump drain media emanating from different buildings (6) to and into the ring conduit for transport therein through pumping action. Devices (27-31) for taking care of drain media are connected to the ring conduit through a branch (12, 13) each. Valve members (24, 25, 32) are arranged in each connection to the ring conduit and optionally controllable so as to either open in the case of a feed connection and allow pumping of drain media into the ring conduit and in the case of a device connection allow drainage of drain media from the ring conduit, or close to stop drain media from flowing into or out of the ring conduit.
