China - Jiangsu Water and Wastewater Project : environmental assessment (Vol. 5) : Environment management plan (English)

The objective of the Jiangsu Water Supply and Wastewater Project (JSW&WP) for China is to enhance infrastructure services and support urban growth and economic development in Jiangsu Province. The major potential adverse environmental impacts during both construction and operation periods include: noise, odour, dust, traffic congestion, and sludge disposal. Mitigation measures of the project are: 1) construct temporary sewage treatment facilities, such as retention tank, sedimentation tank, oil separation tank, drainage ditch, and collect the wastewater according to different types; 2) construct temporary toilet facilities in construction camp, treat wastewater in septic tank and underground sewage treatment device. Domestic waste will be discharged into the local sewer collection system if available; 3) avoid excavation and backfill in rainy seasons; 4) spray water before excavation to avoid dust generation. Transport and backfill soil and construction waste promptly; 5) cover and wash vehicles, no overload, spray the roads 4-5 times a day; 6) manage traffic properly to avoid traffic congestion; 7) stop construction work in windy weather; 8) arrange construction time properly, notify the local residents in time, and comply with the standard for permissible noise level for construction sites; 9) take noise reduction measures, locate machinery at points with lowest impacts on residential areas nearby, set up temporary noise barriers around stationary noise sources and temporary fences on construction sites; 10) store spoil and construction waste generated properly during construction, treat them centrally and transport them promptly, to avoid pollution of river courses and sewer congestion; 11) farmers should be compensated for the land to be temporarily acquired in compliance with the national standards; and 12) stop taking water immediately in case of water intake pollution, enhance the monitoring of water quality in water intake region. If the polluted water flows into raw water transfer pipelines, more disinfectant should be added and the amount of backwash water should be increased until the water quality can meet the drinking water standards.
