Preparation of preliminary environmental and social impact assessment of the project.
To develop various conceptual options, preliminary project cost estimates, preliminary whole life cycle cost analysis. To carry out financial analysis and development of decision matrix to select the optimal conceptual solutions.
Identification and prioritization of sub-projects / components to achieve pollution reduction objective.
Master Plan report shall be prepared for the horizon year 2036 and Master plan, Report shall include project formulation, Phasing of works and cost estimation, for the year 2036 including population projections, water demand projections, reorganization of existing sewerage zones. Identification of project components and phasing of works shall be discussed before finalization of Master Plan.
Consultants shall prepare a table of contents for Master Plan/ Feasibility Study/ DPR for obtaining concurrence from PMC/PHED

Phase 2: Feasibility Study

Review of collected documents and data, if required, collection of additional documents and data to further develop the concept. To continue to liaise with various stake holders to seek, confirm and consolidate all users’ requirements. The user parties to be consulted are as given earlier:
Concept, framework and design of the facility planning for the project components shall be determined or confirmed. To make framework and design, possible design alternatives (2 to 3) including capacity and location of facilities shall be identified and examined, and the most appropriate alternative shall be selected.
Additional survey/ lab analysis and investigation such as but not limited to the following shall be carried out to get further required basic data. An inventory survey of existing facilities shall be carried out to identify the need for rehabilitation.
1. Topographic survey works for the proposed major facilities
2. Geotechnical survey works for the proposed major facilities
3. Sewer condition (structural and extent of blockage, siltation etc.) assessment and flow monitoring
4. Water and effluent quality lab analysis
Development of design for sewers (location, alignment, profile, diameter, length, etc.), for pumping stations (capacity, pumps specification, general arrangement etc.) and for Sewage Treatment Plant (process, process flow diagram, mass balance, unit sizes, layout etc.) and project program and cost estimate for each of options (minimum 2) for priority project, including breakdown of costs for civil/ structural, mechanical electrical and instrumentation, control and automation works. Analysis and comparison of options based on overall life cycle costs.
Detailed study and investigation of at least 2 options for sewage treatment methods to meet the effluent discharge standards as laid down by NRCD and the objective of reducing pollution in Yamuna River and recommendation of the best life cycle cost treatment option.
The Consultant shall evaluate the existing organizational structure and propose appropriate and a sustainable organizational structure for managing sewerage facilities including existing facilities. Also the Consultant shall identify the need for capacity building for manpower requirements for running and maintaining the proposed sewerage system including for existing system. A training program for the required manpower shall be formulated.
The Consultant shall prepare the financial plan of the project including construction cost of the proposed facilities and O&M cost of proposed and existing facilities. The plan shall also include tariff level and system, level of subsidies required, costs for human resource development and institution building. A feasible financial plan shall be formulated assuming loan from international funding agencies. Financial and economic evaluation shall be carried out and the economical and financial internal rates of return (EIRR and FIRR) shall be estimated for different infrastructural investment scenarios.
Overall evaluation of the project during feasibility study shall be carried out with the following evaluation items:
1. Technical feasibility,
2. Feasibility of financial and economic conditions,
3. Institution and capacity building,
4. Environmental impact of the project
The consultant shall prepare and develop a detailed schedule of work for implementation by showing broad activities of the project component after discussion with all stakeholders, using MS Project software.
After the preliminary design, development of the preliminary procurement plan for goods and services for the implementation phases.
The consultant shall take into account the need for localized closure and diversion of affected facilities and services during surveying and condition assessment of sewers etc. Proper resources and scheduling methods should be applied so that personnel and vehicular movements, traffic diversion, transport of materials, site storage and hoarding requirements impose minimum social costs such as nuisance, inconvenience and disruption to locals.
Sample table of content and guidelines is attached in the annexure for information to consultant for Feasibility Study.
