WATER RESOURCES MANAGEMENT

Hydromanagement specializes in water resources engineering and has conducted numerous projects related to stream settlement, irrigation, hydrological projects, design of water treatment facilities, telemetry etc.

Water Supply Networks and Water Treatment Plants

A considerable number of water supply networks have been designed, ranging from preliminary to final design, including some highly complicated specialised studies. The projects undertaken cover all aspects of water supply, including transmission and trunk mains, distribution networks, pumping stations, reservoirs, pipe replacement and rehabilitation, water treatment plants and SCADA. A few indicative examples are:

  • Water supply, Sewerage network and Wastewater Treatment Plant for Nsork  in Equatorial Guinea, Africa – design for construction
  • Design of seawater Desalination Plant in Agia Paraskevi – Santorini island – budget of 9.970.000 €. Includes a subsea pipeline, a sea water pumping station and pressure pipeline transporting the sea water to the Reverse Osmosis desalination plant.
  • Water Supply Trunk Main and distribution network for the Imera and Avra settlements in Kozani – 9.000m external, 2.000m mains and 8.000m internal network.
  • Hydraulic Study - Connection of Aliakmonas river intake and trunk main to the existing water supply facilities (Thessaloniki Water and Sewage Company SA –  E.Y.A.TH)
  • Water supply network to settlements of Alonnisos island – Water supply treatment plant and SCADA – 103 ha, 37,5 km network, 35.000 EP
  • Water supply network of the coastal zone of Kato Olymplos municipality - 38.000 EP, 247 ha, 50 km pipeline network.
  • Water Supply to Ithaki island arid areas – includes submarine trunk main and water treatment plant.
  • Design of submarine pipe from Kalochori to Kalamaria (E.Y.A.T.H.)
  • Water distribution network replacement in the Industrial Zone of Kavala City – 15 km internal network, 4 boreholes, disinfection, automation, SCADA
  • Water Distribution network replacement in Assiros Municipality – over 30 km internal network.
  • Water Supply in Industrial Zone of Alexandroupoli’s city -  3.350m pipes, boreholes, storage tank, pumping station.                                       ΔΙΑΧΕΙΡΙΣΗ ΥΔΑΤΙΚΩΝ

Water Supply Network Management & Leakage Detection

HYDROMANAGEMENT has specialized experience in water supply networks operational management and leak detection. The company’s staff experience was acquired through the completion of a number of projects, in collaboration with the British Consultants HYDER and British Leak Detection services providers FLOWCONTROL and HYDROSAVE.

Some of the operational management and leakage control projects completed are:
