Tianjin Hangu is an industrial district. The waste streams feeding to this wastewater treatment plant consists of approximately 70% industrial wastewaters from the district and 30% domestic wastewater from the industries and residents. ESD participates as a member in this Design-Build-Operation (DBO) project consortium. Our team was responsible for organizing wastewater source survey, optimization of process design and cost control, upgrade of process design from the original Class II discharge to current Class 1B discharge with water reuse scheme, variation management, odor control, process commissioning and development of operational plan for the initial 5 years operation. The operational budget for the initial 2 years will be funded by the World Bank Global Environment Facility (GEF).

ESD China undertook the water utility benchmarking study including training workshop, quality auditing, selection of Performance Indicators (PI), and data analysis of the PI results for 30 water supply companies in Shandong Province. The study was funded by World Bank using IBNET benchmarking tool.

ESD was selected to conduct the SVA studies for the two Coke plants in China. The scope of the SVA studies included the following components: a) Gather existing information regarding the regional water resources (surface water, groundwater, geology, water quality and land use); b) Define watershed and study area; c) Conduct land use survey, including vegetation and ecological data; d) Develop a conceptual model of the surface hydrology, geology and hydrogeology of the area; e) Identify potential polluting sources (for both surface and ground waters), source vulnerability, and define zones of protection for the water sources; and f) Document the required information and recommended mitigation strategies. Through the project, ESD developed GIS-based assessment model to evaluate the environmental vulnerability of the water supply source to the bottling plants.

ESD is engaged to provide technical assistance (TA) to the client to develop a comprehensive septic management system including on-site wastewater treatment management. The TA consists of development of proper policies and regulations for septic management, institutional settings, selection of affordable on-site wastewater treatment technologies, development of septic tank and septic truck operation and maintenance manuals, training, cost and financial analysis, and replication and dissemination of successful experiences. A GIS platform will be built to bring together the final management system.

ESD in association with Louis Berger Group (USA) jointly undertook this Technical Assistance (TA) in institutional analysis and managerial strengthening. The assignment included provision of guidance and assistance in developing corporate business plan, financial management and accounting procedures, operation and maintenance quality plan and manuals, and organizing domestic and international training for newly established wastewater companies in 8 project cities. In order to meet the World Bank loan conditions, the focus of the project included provision of assistance on corporatization of wastewater companies and financial/affordability studies.

ESD, in association with a number of parties at different stages, was engaged by Tianjin World Bank Project Office to undertake a number of Technical Assistance (TA) task packages. The project included sediment dredging, dewatering and landfill disposal for 83 km Dagu Sewage Discharge Canal. The TA provided professional advice covering sampling, pilot trials, design review and landfill operation and construction, leachate treatment, and construction management services. In addition, a comprehensive environmental impact mitigation plan (EMP) was prepared for this large river sediment dredging project, tackling construction/traffic noise, safety, and air emission impact to the communities along the river bank.

ESD staff was seconded to Halcrow Group (UK) acting as the project manager for TA construction management. The assignment includes preparation of bidding documents, review of pre-qualification evaluation reports, bidding process management, design review, construction management and project management in line with World Bank policies and procedures. The project included 2 wastewater treatment plnats and 600 km sewer pipelines and pumping stations within 8 cities.

ESD staff was sub-contracted to Ecology & Environment Inc. (USA) to assess these additional works and to produce feasibility studies to identify and cost specific projects, in sufficient details to enable the Client to obtain World Bank funding. The feasibility study for the Longwangzui secondary treatment facilities included the following components:

• Study of the environmental impact on the South Lake, the receiving water for the effluent, from the Longwangzui Wastewater Treatment Works
• Study of potential secondary treatment process alternatives in order to achieve the required water quality standards.
• Preparation of outline design layouts for the secondary treatment alternatives
• A financial and economic assessment of the proposed works together with full project costing.

ESD staff worked as a sub-consultant to Halcrow Group (UK), responsible for survey of pollution sources, discharge permit system, and implementation enforcement of pollution control legislation and providing professional advice on pollution prevention and control solutions, cleaner production technology, and priority investment programme.

ESD staff was sub-contracted to Ecology & Environment Inc. (USA) to assess these additional works and to produce feasibility studies to identify and cost specific projects, in sufficient detail to enable the Client to obtain World Bank funding. The additional works proposed includes the provision of additional sewer collectors in three areas of Wuhan. The feasibility study for the Wuhan Wastewater Collectors included the following components:

• Assessment of the existing sewerage situation in three project areas
• A study to optimise the benefits of additional sewerage facilities in the project areas
• Production of outline designs for the additional sewerage including associated pumping stations
• An environmental assessment of the impact of the proposed works
• A financial/economic assessment of the proposed works together with full project costing

ESD seconded experienced water resource manager to act as Regional Water Resource Manager of TCCC to lead preparation and implementation of Source Vulnerability Assessment and Source Water Protection Plan for the whole China Division which has 36 bottling plants throughout mainland China, Taiwan, Hong Kong SAR. Detailed duties include developing/testing GIS systems, water supply vulnerability assessment, coordination of consultants and internal/external agencies and training.

Yuqiao Reservoir is the main drinking water supply source for Tianjin (Provincial) Municipality with a population of over 7 million. ESD China professionals are working with US EPA specialists to manage a demonstration project for water resources protection, including identification of non-point water pollution sources, pollution control measures, flood control, and reservoir water quality management including manure compost and agriculture best practice to prevent from runoff pollutions to the reservoir.

ESD staff was sub-contracted to Ecology & Environment Inc. (USA) to assess these additional works and to produce feasibility studies to identify and cost specific projects, in sufficient detail to enable the Client to obtain World Bank funding. The additional works proposed included the provision of secondary treatment facilities for the Hanxi Wastewater Treatment Plant in Wuhan, Hubei Province. The feasibility study for the Hanxi secondary treatment facilities included the following components: a study of the water quality issues for the Fu River in the vicinity of the Hanxi Wastewater Treatment Works site; a study into potential secondary treatment process alternatives in order to achieve the required water quality standards; Production of outline design layouts for the secondary treatment alternatives; a financial/economic assessment of the proposed works together with full project costing.
