1.1 BACKGROUND

The Karnataka Municipal Reforms Project (KMRP) is a US$ 310 million (Rs.1364 crore) IBRD financed project that is fully consistent with the World Bank’s Country Assistance Strategy and focuses on working on governance issues and sectoral projects. The KMRP comprises of four major components, which include (i) Institutional Development; (ii) Bangalore Development; (iii) Municipal Investment Support; and (iv) Project Management. Broadly, KMRP would assist institutional development activities statewide and infrastructure development in 32 Urban Local Bodies (ULBs) as per GO No. UDD 56 PRJ 2005 dtd 13.09.2005.

1.1.1 PROJECT OBJECTIVES

1. Enhancing the capacity of Urban Local Bodies to discharge their functions in accordance with 74th Constitutional Amendment with a greater sustainability and accountability.

2. Strengthen institutional and financial frame work in urban service delivery at ULBs level and State level.

3. Improve the quality of urban infrastructure in 32 (ULBs) and

4. Improve the road system in Bangalore and the sanitary conditions in the 8 erstwhile ULBs surrounding Bangalore city, while ensuring financial viability and sustainability.

The Municipal Investment Support Component is to be managed by KUIDFC, working in close coordination with DMA’s office, the DUDCs and the ULBs. 32 ULBs are divided into 4 packages. Package-1 with 9 ULBs, 2 with 5, 3 with 10 and 4 with 8 ULBs respectively.

While the project is expected to improve the environmental conditions in selected urban areas of Karnataka by improving the quality of service, development ofinfrastructure including water & sanitation and substantial health benefits. Adverse social and environmental impacts are anticipated if the investments are not properly planned, sited, designed, constructed, operated and maintained.

Considering these aspects, GoK plans to integrate social and environmental issuesin the project at policy and sectoral levels. This will be achieved throughPreparation of Social Assessment and Resettlement Action Plan and Environmental Assessment (EA), Environmental Management Plan (EMP) at project level as required and appropriate.

1.1.2 OBJECTIVES

The objective of the present assignment is to prepare Social/Resettlement and Environmental Management Plans for the works proposed under KMRP andintegrate the concerns in the design. The scope includes the following:

providing social and environmental inputs into action plan

Chitradurga

planning for social and environmental activities to be carried out duringproject preparation and implementation

providing guidance / quality assurance for integration of environmental and social aspects in the work

preparing RAP and EMP as required as per SEMF

integrating finalised EMP into the contract for implementation and operation

1.1.3 METHODOLOGY

Identification and review of all the relevant policies and regulations that influencethe project environment is very important to assess the impacts on projectplanning and implementation. In view of this, review of all applicable operationalpolicies / directives of The World Bank and environmental laws / regulations inIndia, is carried out in the Social and Environmental Management Framework. This included review of the operational policies of The World Bank.

A Capital Investment Plan (CIP) was prepared in 2005 based on the ULB borrowing capacity. Based on CIP and SEMF including the policy, regulatory and institutional mechanism, a detailed review of the project and the proposed sub-projects in the ULBs was carried out and Detailed Project Reports (DPRs) wereprepared. This involved discussions with the project ULBs to understand thepresent basic infrastructure status.

The project profile primarily focused on identifying the various activities that are envisaged for providing the basic infrastructure and the details of priority investments that are planned for each of the project ULB.

In addition to the above, the key environmental regulations / policies in India that may affect /influence the project environment both during preparation andimplementation stage are also reviewed.

1.1.4 REVIEW OF INSTITUTIONAL MECHANISMS FOR ENVIRONMENTALMANAGEMENT

A detailed analysis of various stake holder agencies who will be involved inplanning, designing, operating and maintaining the infrastructure that are beingdeveloped by the project and other improvement measures are important to assess the capacity, willingness and resource requirement of the institutions for effective integration of environmental concerns. More specifically, the environmental impacts will be influenced by the manner in which the project components are designed.

In view of this, a review of institutional and organisational set up of theinstitutions and beneficiary agencies are carried out.

The review primarily focuses on the role of each of the above agencies in various stages of project development. An assessment of technical and managerial

Chitradurga has some important tourist spots like Chitradurga Fort, Obavvana Kindi Vaani Vilas Sagara, Murugha Rajendra Bruhanmatha & Chadravalli Garden.

1.2.3.2 History

Chitradurga features bold rock hills and picturesque valleys, huge towering boulders in unimaginable shapes. It is known as the "stone fortress" (Kallina Kote). The landscape looks much like a mischievous giant's playground, with boulders thrown around, forming silhouettes against the sky. According to a story in the Epic Mahabharatha, a man-eating giant named Hidimbasura lived on the Chitradurga hill and was a source of terror to everyone around. When the Pandava came with their mother Kunti in the course of their exile, Bhima had a duel with Hidimba. Hidimba was slain by Bhima and peace returned to the area. Legend has it the boulders were part of the arsenal used during that duel. In fact, the boulders on which major part of the city rests belong to the oldest rock formation in the country. Timmana Nayaka a chieften under the Vijayanagar empire rose to the rank of governor of Chitradurga as a reward for his excellence in military achievements, from the Vijayanagara ruler. This was the beginning of the rule of the Nayakas of Chitradurga.

It can be summarised from the environmental-social profile in the preceding sections that the Chitradurga town do not present any sensitive environmental features that could be affected by the proposed implementation.

1.3 IDENTIFICATION OF SOCIAL AND ENVIRONMENTAL IMPACTS

For the purpose of assessing the impacts, a summary of the same and various activities involved in execution of the Infrastructure components.

1.3.1 PUBLIC CONSULTATION

The willingness of the public and their expectations on the service levels is very critical in accomplishing the objective of improving the level of service in the project towns. For this purpose, Public Consultations were conducted.

The objective of these public consultations was to elicit public view on the present status of infrastructure, problems and issues associated with the same and their expectation on the proposed project. The economic, social and environmentalissues associated with the same were also identified during these public consultations. The results of the public consultations provide an input to identify the impacts of the project proposals and subsequent formulation of EMPs.

1.3.2 CONSTRUCTION AND OPERATION PHASE

The impacts on physical resources such as topography, climate will be insignificant or no impact. Whereas impacts on the environmental resources (Surface water quality, groundwater quality, air, noise); ecological resources and human use values (Soil, Archaeological / Cultural Properties, Social Impacts) will be very minor and temporary, however the measures presented subcomponent-wise will mitigate the possible impacts during construction and operation phases.

1.4 ENVIRONMENTAL MANAGEMENT PLAN

No major environmental impacts are anticipated due to the proposed development. The critical issues will be to ensure adequate safety and precautionary measures to minimise impacts during construction and during operation. Any specific impacts arising during execution has to be analyzed and appropriate mitigation measures taken accordingly.

While the impacts are not very severe and permanent, care has to be taken to ensure that the ambient environmental conditions do not deteriorate. The recommended mitigative measures to the impacts on key environmentalparameters are detailed out subcomponent-wise in the following sections.

Regular maintenance of infrastructure components will be carried out by the ULB. Equipments will be procured for operation and maintenance of the implemented infrastructure. Regular monitoring of implementation of the proposed infrastructure shall be carried out.

1.4.1 BENEFITS FROM THE PROJECT

The proposed infrastructure components would increase the effectiveness of the water supply, stormwater disposal, RWH, traffic & transport and slums in the town by providing better infrastructure facilities. The proposed work will provide better health benefits for the public, preventing water borne diseases arising from the improper stormwater disposal system. Also, the proposed work will prevent the contamination of due to improper disposal of stormwater. The ground water contamination will also be arrested by allowing the sewage to flow in the pipeline. The beneficiaries will comprise households of the town.

1.5 SOCIAL / RESETTLEMENT ACTION PLAN

All the rainwater harvesting structures are proposed over existing buildings and no additional land will be required for the project. Also, the road network an stormwater drainage proposed to be developed as a part of the project shall be aligned over government land and no private land is proposed to be acquired. Further water augmentation and slum upgradation will be on existing land. Hence, issues related to resettlement and rehabilitation are not envisaged in the proposed project.

But in order to shift the electric poles and telephone poles the involvement of concerned authorities are necessary for road improvement works.

No major social impacts are anticipated due to the implementation of proposed infrastructure. The critical issues will be to ensure adequate safety and precautionary measures to minimise impacts during construction and operation phases to the standards prescribed by KSPCB during operation.

General Hospital (B&C Wings)

Lokayukta Office

Krishna Rajendra Library

General Hospital one of the important land mark of the town and is situated close to CMC building on the Bangalore – Poona National Highway. It is a partly stone building and has approximately 3682 m2 area with wards in the first floor. There is a sump in the frontside of the General Hospital. It is proposed to harvest the roof top rain water and lead in to the sump for storage and use. The building has ample open space within and it is being used for maintaining gardens. The building has drain pipes both of PVC and AC inside as well as outside but most of it (110 mm dia) are broken or damaged. Hence, only the pipes which are in good condition are being used for vertical and horizontal collection. A total of 463m drain pipes are being dismantled out which pipes which are in good condition are being retained for vertical collection. The water that is likely to the harvested will be around 11,69,000 liters and the total estimated cost Rs. 5,98,000/-.

Lokayukta office is situated on the main road that is on NH4 and on the way to the KSRTC bus stand. The office is located in a building which is situated inside the compound and front portion of the compound converted to shops. The building has a built up area of 468 m2 and the top is partly of tiled roof. It has a sump and there is a hydro met station and an observational bore well in the backyard which is being used to record water level changes periodically. It is proposed to harvest rain water from the roof top and store it is the sump and the excess flows lead to the bore well to recharge ground water. The building has 90mm dia drain pipes which are partly good and partly damaged condition. A total length of 34m of pipes have been dismantled and the pipes in good condition have been utilized for vertical collection. The total estimated cost is likely to be Rs. 1,35,200/-. The water that is likely to be harvested will be 2,41,860 litres.

The Krishna Rajendra Library is situated in the heart of the town is on the NH4 and is above a half Km from the CMC building. It has an old British architecture type building (like the public library of Bangalore) and has two annex newly builtRCC buildings. There is a bore in the premises. For roof top harvesting purposes only the main building and one of the annex building is considered and the total roof area is 379 m2. The harvested roof water will be lead in to the bore well for recharging ground water. The main building which is an old building has only pipe projections to drain out rainwater where as the annexe building has drain pipes. A total of 22.3m pipes are being dismantled and the pipes which are in good condition are being retained for vertical collection. The total water that is likely to be harvested will be 1,95,860 liters and the estimated cost for the harvesting will be Rs. 1,33,400.

Most of the roads are in worn out condition with lot of pot holes and patches. Except for a few roads there are no pucca drains to carry the storm water. The interior roads are mostly having gravel and metal riding surface without proper drainage arrangement. In some of the new extension areas there are only earthen roads. Due to paucity of funds resulting in poor maintenance, the riding surface is in dilapidated condition. The traffic experiences difficulty in passing over the roads besides the problem of dust pollution.

1.7.2 REHABILITATION/IMPROVEMENT OF ROADS

The revised list provided for rehabilitation of 91 roads for about a length of 32.67 Km for various widths of carriage ways for providing bituminous and CC riding surface over different types of existing surfaces like earthen, metalled and bituminous surfaces. It also envisaged rehabilitation of 94 numbers of culverts and road drains for stretches where no pucca drains.

1.8 STORMWATER DRAINS


For drainage of storm water during rainy season and avoiding the flooding of low lying areas and water stagnation it is necessary to provide the drainage pathway for proper disposal of storm water from the developed area. The storm water drainage system in Chitradurga is predominantly open. The major storm water drainage network comprises of the primary drain from Kanaka Circle to Holalkere Road (NH4) which runs for 2.725 Km length in North ward direction inside the town. Road side drains from different parts of the town join this main drain.

Some portions of the drain needs desilting to facilitate smooth flow during rains. The main drain passes through the built up area of the city and is filled up with debris and encroached in some stretches. This results in water stagnation during rains leading to mosquito and contamination of under ground water sources which makes it more necessary to provide storm water drains from hygienic point of view.

1.8.2 PROPOSED DEVELOPMENT

At present storm water drains carry waste water from about 60%of the town because of non existence or non performance of underground drainage system in some of the areas of the town. Remaining 40% of the city area is not covered by storm water drains.

Three major open drains are discharging their waste in Baragere kere, which carries sullage and sewage from the households polluting the tank. In order to prevent the pollution of fresh water in the tank and also ground water, it is necessary provide suitable storm water drains to avoid the sewage entering into

1.9 SLUM INFRASTRUCTURE

1.9.1 EXISTING INFRASTRUCTURE

The total local network comprises of lanes & streets roads for a length about 107.5 Km. Of these about 58 Nos of roads for a length of about 8.85 Km is taken up under this sub component. These roads cater the needs of main traffic inside the city and are provided with bituminous and rigid riding surface with carriageway ranging from 3.0 to 5.50 m.

Few roads there have no pucca drains to carry the storm water. The interior roads are mostly earthen or having gravel and metal riding surface without proper drainage arrangement. In some of the new extension areas there are only earthen roads. Due to paucity of funds resulting in poor maintenance, the riding surface is in dilapidated condition. The traffic experiences difficulty in passing over the roads besides the problem of dust pollution.

Santhe Maidhan is situated in northern part of the Chitardurga town, 800 m away from the KSRTC bus stand. There is burial ground and private bus stand closely situated near the area. The habitation living around the area belongs to low income group .i.e below the poverty line. The space in and around the area is presently occupied by the vehicle repairing garages. Every Monday there will be trading of vegetables .i.e. (Sandy day santhe). To boost up their standard of living conditions by providing good hygiene conditions, a market yard covering a area of 60 m x 30 m is proposed with 102 shops is proposed. By providing this market, there will be increase in revenue collection to the municipality.

1.9.2 UPGRADATION OF PHYSICAL INFRASTRUCTURE IN SLUMS

The revised list provided for rehabilitation of 58 roads for about a length of 8.85 Kms for various widths of carriage ways for providing bituminous & concrete riding surface over different types of existing surfaces like earthen, metalled and bituminous surfaces. It also envisaged rehabilitation of 75 numbers of culverts and road drains for stretches where no pucca drains.

The ULB has also proposed to take up the construction of Sante maidhan market, providing cover slabs on existing storm water drain in Budda nagar slum and providing basic facilities for the residents of Mandakki batti.

The market yard is designed as a pitched roof covering a plan area of 60 x 30 m comprising of steel angular trussess resting on concrete columns. The structural analysis of the structural was performed by Staad pro with various load combinations of live load, dead load and wind load (basic wind speed 33 m/s).The steel angular truss will be covered with 0.5 mm galvalume sheet which is more corrosive resultant than conventional sheets. The market yard will also be provided with civic amenities like roads, water supply and electrification.

capacity. The WTP is located at outskirts of Hiriyur near NH-4. WTP comprises of aeration, flash mixers, chemical coagulation, clarifier, rapid sand filter and treated water sump. Filtered and chlorinated water is pumped using 320 HP centrifugal pumps, 2 Nos. (1W+1S) through 400mm dia C. I. ‘B’ class rising main over a length of 18 km and water discharged into a rectangular sump of 1.00 lac liters capacity at intermediate pumping station.

Non functional Water Treatment Plant at Hiriyur

The status of various units/equipments of water treatment plant is given in following table.S. No. Component Present status of the component1 Aerator : The aerator is in good working condition2 Raw Water channel : This requires reconditioning by repairing the plastering on removing

the old plastering & installing raw water meter.3 Flash Mixer : This requires to be improved by attending fresh plastering the side

walls, bottom & external sides. The agitator assembly including support frame, 3 HP motor (3 PH-415 volts). Reduction gears and coupling are out of order and the unit required to be replaced with new fixtures.

4 Clariflocculator : The electro-mechanical component is not in order, and found to be totally unserviceable and cannot be repaired. Hence supply of scraper bridge assembly including drive carriage viz., motor, gear box assembly, central bearing, slip ring apparatus, rubber squeegees and M.S. track are required to be replaced in order to recondition the systems.

5 Rapid sand gravity filters : The RPS filtration is not in order and the system is found to be not working. It is advisable to recondition the system by total revamping by providing of pipe gallery and out let valves of 400mm dia & back wash valve of 300mm dia. Also, providing fresh filer media as per technical specification, further filter apparatus including LOH & ROF meters & ROH controllers, are to be provided.

6 Chlorinators : The apparatus are in good working condition on improvements of the treatment plant as detailed above, this will ensure a potable, water supply of 9,08,000 Ltrs (2 MGD) for a population of 1,50,000 at 60 LPCD with proper chlorination, as the ion exchange chlorinators installed are under good working condition.

7. Electro-Mechanical fixtures & Filter Media

: Again, the present status of electro mechanical fixtures provided have been inspected, under the water treatment plant at Hiriyur on 29.08.2007. Due to lack of maintenance, Alum mixing tank apparatus, flash mixing devices and clariflocculator bridge in the treatment plant are required to be changed by new fixtures; Including wiring and controls needs to be replaced. Further, the filter media is formed to be totally worn out and un serviceable, hence required to be replaced conforming to quality standard prescribed by CPHEEO: to ensure supply of potable water to the public in particular with due chlorination. Also, the pipe gallery is found to be very old and not suitable to screen the water and this has to be replaced newly, along with control valves and control meters and equipping of required laboratory apparatus.

Water Supply arrangements from TP for supply to the Chitradurga City.

: The treated water from the filter plant is conveyed to 70,000 ltr. Capacity pure water sump in the treatment plant area. (50’ x 24’ x 10’) water from this sump is then pumped to IPS (25’ x14’ x 12’). 21,000 ltr capacity sump at Burujanakoppa through 400mm CI pure water rising main 23Km length. Originally there were 2 No. of 150 HP pumpset with 1 No. of additional pump set on stand by. As these pumps are out dated and involving frequent repairs, as such in 1984, 2 Nos. of 300 HP pumpset with 1 No. as stand by was installed. Again during 1997-98 under Deputy Commissioner scarcity relief fund 2 Nos. of 320 HP pumpset were installed and now presently, these pumps

S. No. Component Present status of the componentare in working condition and providing water supply in the city. Earlier, at IPS 2 Nos-140 HP pumpset and 1 No. as standby was provided. But, the pumpsets were out lived involving frequent repairs and also of low discharge capacity. As such during 1984, 2 Nos. of290 HP pumpset were installed, of which 1 No as standby. Again during 1997-98 under DC scarcity relief fund 2 Nos. of 300 HP pumpset were installed, of which 1 No. as standby and with this, water supply is made in the town. Further from this IPS, water is again pumped to sump of 5000 gallons (40’ x 20’ x 10’) capacity located near Kanave Maramma temple through 400mm dia CI rising main of 10.30 Km. From this reservoir water is then distributed through 400mm dia CI of gravity main of 5.40 Km length to existing GLSR and OHTs. Thus water obtained from Hiriyur TP is distributed to following reservoirs to distribution network pipes and also directly supplied to distribution pipes.

1.10.2 WATER SUPPLY AUGMENTATION

It is proposed to provide new electro mechanical fixtures to the flash mixer alum tank and clari-flocculator etc. Further, it is observed that the plastering provided for the above component works for interior and exterior are also required to be dismantled and good plastering in cement mortar of requisite proportion is to be attended in order to achieve proper water tightness of the component. Thus, necessary repairs for attending plastering to this works are proposed.

The rapid sand filter is found to be unserviceable and it requires total revamping of filter media and filter sand. Hence, it is proposed to provide filter media as per CPHEEO standards on removing the existing filter media and attending repairs to filter box viz., plastering the cement mortar both inside and outsides of the filter box and proposing cement mortar grouting to the bed to fill the cracks and crevices in order to recondition the filter box for water tightness. Anti-corrosive painting for the interior of the filter box is also proposed.

Electro-mechanical equipments required in case of alum tank and flow meters, gauges, valves, etc. for the filters for inlet and outlet connections as well as for wash water pipe have been proposed in place of worn out and unserviceable valves and fixtures in accordance with Dondeli model. The estimate has been prepared based on Dondeli treatment plant repairs model. For laboratory apparatus and safety equipment rates approved under Dondeli model for repairs to treatment plant has been estimated it amounts to Rs. 1,20,000/.

On improvement of the treatment plant by attending the above repairs and installations and proper chlorination. water shall be treated to the standards specified as per IS 11095. besides this necessary laboratory apparatus required for testing of water samples together with safety equipments have been proposed.

It is envisaged that mitigativemeasures for the construction phase impacts will form part of tender documents inviting proposals for construction. The responsibility for their compliance thus would be binding for the prospective contractor as the contract condition. Theoverall responsibility for implementation of mitigative measures will, however, rest with the project implementing agency, which will supervise the construction ofimprovements.

The implementation of mitigation measures are the responsibilities of the Contractor/PC/ULB. However, the mitigation measures during construction phase will be the full responsibility of prospective Contractor. The PC/ULB would be responsible only for monitoring/supervision/guidance, etc. Liquidated damages are also recommended on account of non-compliance of EMP provisions.
