Phase III of the construction of the Ljubljana Central Treatment Plant dominates this area of the vision. One of the largest environmental projects in the city, it aims to ensure efficient use of the capacities of the facilities as well as greater energy self-sufficiency of the plant.

The urban waste water discharge systems in the neighbouring municipalities of Medvode and Vodice will be upgraded by the end of 2015, leading to the construction of the C0 connection channel in Ljubljana proper. This channel, running from Brod to Sneberje, will enable the connection of the neighbouring municipalities to the central sewerage system in Ljubljana itself. The idea is that greater access to the sewerage system will mean improved management, and the construction of this 10.5km long channel is estimated at €13.5m.

The main aim of this is relieve the pressure on the central sewerage system. By reducing the inflow of waste water currently pumped in from lower-lying areas of the Sava, the operating costs of the entire system can be reduced. One location should mean better control after all.
