EXTERNAL WATER SUPPLY SCHEME

Technical Feasibility of WaterIntake :

GGPL is in the process of setting up a 135 MW Power Project using Lignite as fuel.Condenser cooling is proposed through a closed cooling water circuit with induced draftcooling towers (IDCT). The site has been identified and the map showing the details of

the proposed site is attached as Ann.1

The purpose of this study is to examine the technical feasibility of getting requisite

water from the nearest water source. In this case the nearest water source identified is

river Tapi which is near to proposed site. Based on preliminary information, the river is

perennial and it is feasible to draw water from the Tapi river.

Water requirement

The total water requirement for the proposed Power Project will be around 15 KLD.

The first phase, expected to be commissioned by end of 2010.

Scope of Work :

Part-I Technical Feasibility of Water Supply Scheme

1. Study of the source of water : The consultant should carry out investigationsand detailed survey of proposed source i.e. TAPI river. This should include

collection of water flow data for last 10-15 years, study the water flow levels,the river path, any variation that has taken place with the course of time. HFL,

meteorological data, water temperature measurement, information on

seasonality of temperature and flow, etc. The consultant should prepare month-wise water levels in the river based on the historical information. Based on the

analysis, the consultant should draw conclusion about the possibility of getting

the requisite ultimate quantity of water, quality of water, about seasonal

variations, and about storage capacity requirement within the plant.

2. Examine the feasibility of various alternatives to draw the requisite quantity of

water from the river. This should include, but not limited to examine possibilityof getting river water by creating some storage mechanism at river end, getting

river water directly, creating French Well etc. Based on this analysis, the

consultant should suggest technically feasible and most cost effective option.

3. The consultant shall carry out water analysis and shall consider any seasonal

variations which are expected in determining the quality of the water usinghistorical data on water quality.

4. Based on the outcome of the water analysis and requirement of water quality,the consultant should suggest raw water treatment facilities such as filtering,

clarifier (clarifloculator), chlorination etc.

5. Suggest the most appropriate intake system, which shall;

Provide adequate quantities of water under all conditions

Provide water of suitable quality under all conditions.

Flexible for gradual and incremental addition in the built up capacity

Design the system considering the phase-wise water requirement.

Propose the in-situ storage under worst conditions of water intake.

6. Once the technical feasibility of getting the requisite quantity of water is

established, the consultant should suggest the best way of transporting the waterto the site. The consultant shall consider all possible alternatives and assess the

technical feasibility of each alternative, and suggest the technically feasible andmost economical solution.

7. The consultant should identify the place within the proposed site where thestorage facility can be created. The consultant shall study various alternate

locations within the site and suggest the most suitable cost effective location.

Based on the storage capacity requirement, the consultant should suggest type ofstorage facility i.e. open pond, closed concrete tank, over ground, underground

tank etc. The consultant should suggest the facility which is most economical.

8. The consultant should also study the environmental aspects. The scheme by the

consultant must meet all the environment related rules and regulations.

9. The consultant should also study what kind of permissions will be required totake from the State Government or any other statutory authority for

implementing the water supply scheme.

Part-II Basic Engineering of Water Supply Scheme

1. Based on the conclusion arrived at during part-I of the study, the consultant

should design the water supply scheme. It is not expected to carry out a detaileddesign; however, the consultant should be able to provide the design on which

basis EPC bids can be invited. The design should include, but not limited to,

1.1 Broad specifications for equipments and data sheets.1.2 Layout drawings.1.3 Pipe routing.

1.4 Storage facility details.

1.5 Buildings envisaged.1.6 Power feeding arrangement.

1.7 BOQ.

1.8 Any other details required for obtaining the firm price bid on EPC basisfor complete job.
