The need to introduce remediation and treatment technologies in the water cycle was recognized by the European Commission under the 5th and 6th Framework Programme and several research projects aiming at improving WW treatment techniques through process optimisation to minimise environmental impacts from WW treatment were funded. In parallel various initiatives are being conducted at the national level, both in the EU and Mediterranean Partner Countries (MPC). However, the communication gaps still existing among scientists and local communities (and water users) and the lack of networking among different Mediterranean countries are the main obstacles to more efficient use of the gained knowledge. The INNOVA-MED Coordination Action will include 7 EC funded project s (P-THREE, CADOX, EMCO,AQUACAT, EmWATER, WATERBENCH and HOLIWAST), dealing with wastewater treatment and water management: 2 from the EESD programme (5th FP); subprogramme area: Waste water treatment and re-use, 3 from the INCO programme (for Western Balk an Countries and Developing countries and Newly Industrialized States), one from Policy-orientated research programme - Scientific Support to Policies (SSP) (Scientific Supportto Policies) programme and one project from the EU-MEDA programme. The main objective is to explore the synergies of the research carried out within different programmes and countries (eg. ED, WBC, DEV, NIS, MCP), to coordinate the research activities of ongoing EU and national projects dealing with development of innovative technologies for wastewater treatment and treatment and disposal of sludges and with application of innovative practices for re-use of reclaimed water and to facilitate the communication with researchers and national and regional institutions from the MPC and allow a broad dissemination and transfer of the knowledge/technology/practice to the Mediterranean area.
