The Mornos Aqueduct is gravity aqueduct with a total length of 188,5 km. It connects the Mornos Reservoir with the Aharnon WTP, and it is made up of tunnels (67,5 km), canals (113,5 km), and inverted siphons (7,5 km). The daily capacity of this aqueduct (up until the Meristi node - 40 km upstream of the Aharnon WTP) is approximately 1.800.000 m3.

Along the Mornos Aqueduct, there are points with a significant elevation differential. At these points there are special structures that destroy the excess hydraulic energy in an attempt to control and normalize the hydraulic flow. In an effort to utilize this hydraulic energy EYDAP is in the process of constructing small hydroelectric power plants at the above locations. These hydroelectric are estimated to produce 40GWh of electric energy.

Given the extended length of the Mornos Aqueduct, there are an adequate number of technical works along its path in order to control and monitor the project’s operation safely (Energy Dissipation Works, Penstocks, a Central and four Regional Control Units). All these installations are integrated with the SCADA system, and aim to telemonitor and remote control the aqueduct from the Central Control Unit, which operates at the Aharnon WTP.

The Mornos aqueduct’s SCADA system, in combination with the special hydraulic software installed for the smooth operation of the project, enables EYDAP to dynamically regulate the Mornos Aqueduct and the Connecting Mornos-Marathon Aqueduct automatically. The ability to continuously adjust the flow rate and the supply capacity of the aqueduct system to match the fluctuating demand of Water Treatment Plants is referred to as the dynamic regulating of the Mornos Aqueduct.
