1. INTRODUCTION

1.1. Background of project

M/s Puravankara Limited has constructed 990 Residential apartments by name “Cosmo City” located at Survey Nos:53/3,53/4,53/10B,55,56/1,57/2 & 57/4, Pudupakkam Village Chengalpattu Taluk, Kancheepuram District, Tamilnadu an expansion to 1184 apartment (Ref: SEIAA/TN/EC/8(a)/006/F-20/2008 dated 24.07.2008). The total Plot area of the Residential apartment Project is 1,27,570.85 Sq.m & the Built up area for expansion is 87,019.40 Sq.m. The total built up area for 2174 apartments (1184 + 990) after expansion is 1,91,215 Sq.m.The building is designed by Renowned Architects and the structure is designed to Seismic Zone specifications-One level higher than mandatory requirement by the government NFPA Compliant Building. Ample parking space has been planned. Water Supply from CMWSSB & sewage treatment plants to keep the environment free from pollution & also rain water harvesting is taken care. Total power requirement is taken care by means of TNEB & the building shall have power backup.

Since the project is construction of buildings, it requires Environmental Clearance from State Environment Impact Assessment Authority (SEIAA) under sector 8(b) of EIA Notification 2006. As Puravankara have started the construction without obtaining prior EC, the file has been delisted by SEIAA and project is pending for want of Environmental Clearance. In order to obtain EC from MoEFCC we are applying to EAC, MoEFCC to get EC as per the procedure prescribed in Notification dated 12.03.2017.

In this regard, M/s Puravankara Limited has appointed M/s.ABC Techno Labs India Private Limited, , accredited by National Accreditation Board for Education and Training (NABET) – Quality Council of India (QCI), New Delhi to formulate Environmental Management Plan during Construction & Operational Phases to mitigate any adverse impacts to the Environment.

The Conceptual Plan describes all the details of the project and its specific activities are considered for investigation of the significant adverse impacts. The report also provides specific measures that are put to practice to minimize the impacts on the Environment.

3.8Rainwater Harvesting & Storm Water Drain

A rainwater harvesting system comprises components of various stages – transporting rainwater through pipes or drains, filtration, and recharging the ground water through tanks. Percolation pits are constructed for ground water recharge. Runoff from the first spell of rain carries a relatively large amount of pollutants from the air and catchments surface so the system provided with a filtration pit consisting of layers of sand, gravel and pebbles of relevant sizes to remove impurities from the collected rainwater.

3.8.1 Need for rainwater harvesting • Surface water is inadequate to meet the daily demand and we have to depend on ground water.

• Due to rapid urbanization, infiltration of rain water into the sub-soil has decreased drastically and recharging of ground water has diminished.

• Rainwater harvesting prevents the flooding of low-lying areas in the site.

• Salinity of ground water is reduced.

CONCEPTUAL PLAN

3.8.2 Rainwater Harvesting Network

All around the compound wall rain water harvesting trenches are provided to collect, convey & harvest the rain water. Hand augured bore holes are planned at appropriate locations & same will be terminated at sandy level. The excess storm water is allowed to drain into the external storm drain available. The trenches are connected around the buildings closer to the compound wall. The depth of the trench is 1.5m and the width of 1m. The trench is filled with rounded pebble 50 to 75mm size. Recharge bore wells are constructed at bottom of the trenches with equal intervals. Depth of bore well is around 15m and diameter of 150mm. A total of 65 Rain water harvesting pits are constructed in the project site (two around each block) to collect and Harvest the rain water from roof tops. The path ways around the boundaries of the project site are graded to facilitate drainage into trenches. Surplus water from the recharge wells/pits diverted to the external storm water drainage network. Details of the rain Water Recharge pit are provided in Annexure VII. The quantity of run-off water potential for the project is given below.

4.3 Green Belt Development To provide a dense tree cover and to provide good sound and dust barriers, the planting of tree species in open areas are done. The recommended plant species are listed in Table 4.5. As per guidelines of TNPCB, the three main criteria for selection of plants may be as follows,  Trees, shrubs will have dense foliage with a large surface area, because leaves absorb pollutants.  The species chosen must be resistant to pollutants, particularly in the early stages of their growth.  The species chosen may be native species and drought tolerant. Table 4. 3 Recommended species for green belt development

CONCEPTUAL PLAN

4.6 Environmental Management Cell

Environment Management Cell (EMC) will look after the environment related matters during the construction and operation phase of the project. EMC will perform the following assignments. • Periodic monitoring of emissions and report any abnormalities for immediate corrective measures. • Periodic monitoring of ambient air quality, ground and surface water quality. • Periodic noise monitoring of the building zone and surrounding area. • Regular monitoring of storm water drains. • Green belt plantation, maintenance, development of other forms of greenery. • Regular monitoring of solid wastes quantity and ascertaining avenues for utilization of solid wastes. • Development & maintenance of schemes for water conservation. The Environmental Management Cell (EMC) will take the overall responsibility for coordination of the actions required for environmental management and mitigation and for monitoring the progress of the management plans and actions to be taken.
