The Asprokremmos dam in Paphos District on the Xeros River holds back the second largest reservoir in Cyprus with a capacity of 53 million cubic metres of water. It is built at an altitude of about 100m above sea level and is located 16 km east of the city of Paphos.
The Asprokremmos Dam is of earth fill construction, standing 55m high. The dam complex comprises the main embankment, spillway, tunnels and galleries. The Asprokremmos Dam was completed in 1982 at a cost of $23,000,000.
The water quality of the reservoir behind the Asprokremmos Dam is remotely continuously monitored using a smart system of satellite remote sensing and wireless sensor networks. These innovative, energy-autonomous floating sensor platforms transfer data via a wireless network to a remote central database. This provides continuous measurements of a range of water quality parameters.
