Recovering from the Great East Japan Earthquake
Sekisui Chemical Group's business is to provide housing and the infrastructure essential to support living.
Utilizing the characteristics of these businesses, it is carrying out a variety of activities to support recovery from the Great East Japan Earthquake.
Contributing to Affected Areas through Various Infrastructure Construction Work and Other Projects
As a recovery from the Great East Japan Earthquake, since FY2011, the Urban Infrastructure & Environmental Products Company has continued to deliver materials for restoration work on sewer pipes that had their gradients damaged in the earthquake. While this is urgent work because damaged roads cannot be restored until the sewer pipes are repaired, it is moving forward at aslower pace than expected due to labor shortages at local construction companies. For this reason, Sekisui Chemical Group member Nippon No-Dig Technology Co., Ltd. (NNT) is contributing to the restoration work by accepting sewer construction directly from the city of Sendai.
In addition, Sekisui Chemical is studying use of sewage heat under a feasibility study on making Sendai a model city for use of sewage heat, under contract to the Ministry of Land, Infrastructure, Transport and Tourism of Japan. This project involves a system for collection and use of heat from sewage during pipe rehabilitation construction using Sekisui Chemical's pipeline rehabilitation method, a technology for rehabilitation and seismic retrofitting of deteriorated culverts.
At the same time, NNT is moving forward with preparations for forming a joint venture with a local firm in the city of Ishinomaki, Miyagi Prefecture, in preparation for future recovery-related demand.
In addition to the above efforts, Sekisui Aqua Systems Co., Ltd. is contributing to earthquake recovery through installation of vinyl greenhouses on a strawberry growing complex for recovery purposes and rebuilding of aquaculture facilities in the town of Watari, Miyagi Prefecture.
Contributing to Improving the Living Environment of Emergency Temporary Housing
Immediately after the Great East Japan Earthquake struck, the Housing Company built a total of 1,160 units of emergency temporary housing in the three prefectures of Iwate, Miyagi,and Fukushima. Later, due to delays in restoration work, the period of residence in temporary housing was extended from two to three years, and the need arose to improve the residential environment for residents. Accordingly, the Housing Company continues to support recovery in affected areas by carrying out additional construction work as requested by each prefecture.
Examples of such additional construction include installation of wind shelters approximately 3.3 square meters in area in front of the front doors to individual residence, to help residents endure the cold winters of the Tohoku region by blocking out cold air. Other efforts to help fight the cold included additional installation of heated toilet seats and, in temporary housing in the particularly cold city of Kesennuma and town of Minamisanriku, distribution of heating equipment.
Since temporary housing facilities are constructed on sites such as unused land and athletic grounds, many are on sites with poor drainage, and some residents have reported that puddles form in pathways and elsewhere. In response, we carried out rainwater drainage construction by installing water-permeable pipes beneath the paths between buildings. In addition, since many residents are elderly, we paved the spaces between units and the parking lots with asphalt, so that residents can move in safety around the temporary complexes.
Furthermore, as the period of residence lengthens, residents' belongings increase, filling up the small temporary housing units. As such, we installed storage sheds next to the front entrance to each unit, contributing to improving the living environment for residents in the temporary housing.
