When sewerage stops functioning because of earthquakes and the consequent damage, there is a long-term effect on civic life. In the Great East Japan Earthquake, an unprecedented level of tsunami caused significant damage to sewage treatment plants and pumping stations. Under such circumstances, the importance of developing sewerage business continuity plans (BCP) has been recognized again and the development of efficient anti-earthquake, anti-tsunami measures is requested. JIWET has been carrying out joint research to tackle earthquakes and the consequent disasters with the aim of realizing a safer and more secure life.
