Wastes of different type such as spent water from bath rooms, water
closets/pans, house and street washings, semi liquid waste of human excreta,
dry refuse of house and street sweepings, broken furniture, crockery etc., are
produced daily. If proper arrangement for collection treatment and disposal of
all the wastes produced are not made, unsanitary conditions will develop and it
will become impossible for the public to live. Therefore, it is most essential to
collect, treat and dispose all the sanitary waste produced. Generally, it has been
observed that about 80 % of the water supplied comes out as sewage. Therefore,
the total quantity of wastewater generated from the proposed Residential
Apartment Project is worked out as below.
Water required for the project = 681 KLD
Wastewater generation : 681 X 0.80 = 544.8 or say 545 KLD

1. INTRODUCTION:
The Environmental Management Plan (EMP) is aimed at mitigating the possible
adverse impact of a project and ensuring the existing environmental quality. The
EMP converse all aspects of planning, construction and operation of the project
relevant to environment. It is essential to implement the EMP right from the
planning stage continuing throughout the construction and operation stage.
Therefore the main purpose of the Environmental Management Plan (EMP) is to
identify the project specific activities that would have to be considered for the
significant adverse impacts and the mitigation measures required.
The construction phase impacts are mostly short term, restricted to the
plot area and not envisaged on the larger scale. In the operational phase the
environmental impacts are due to continuous operation of the project, hence,
the emphasis in the Environment Management Plan (EMP) is to minimize such
impacts. The following mitigation measures are recommended in order to
synchronize the economic development of the project area with the
environmental protection of the region.
The emphasis on the EMP development is on the following;
Mitigation measures for each of the activities causing the environmental
Impact.
Monitoring plans for checking activities and environmental parameters and
monitoring responsibilities.
Role responsibilities and resource allocation for monitoring; and

3.4 SOLID WASTE MANAGEMENT:
The solid wastes generated during operation phase can be categorized under
Three types: Domestic/Residential Waste
Wet Garbage: Food waste, Lawn mowing wastes etc.
Dry Garbage: Paper, Plastic, Bottles, etc.
Sludge from Sewage Treatment Plant (STP)
The solid waste generated and its management is detailed in Annexure – F.
The various mitigation measures to be adopted during collection and disposal of
wastes are as follows:
It is preferable that the container and bins used for collection of waste
should be of closed type and waste is not exposed thus possibility of
spreading of disease through flies and mosquitoes is minimized.
Collection system should be properly supervised so that quick and regular
removal of waste from the dustbin is practiced.
Door to door collection shall be done in each building to collect the solid
wastes.
3.5 STORM WATER MANAGEMENT:
As the project location is blessed with fairly good rainfall, it is planned to
collect the storm water at different gradients of the location. There will be
rainfall runoff from building roof-tops, roads and pavements and greenbelt area.
Necessary provision will be made to collect the quantity of rainfall runoff during
the most rainy day of season. Necessary rain harvesting pit/recharge pit at every
30 m centre to centre have been envisaged. A storm water drain with 600mm
wide with RCC precast perforated cover and 1800 mm dia RCC precast Ring soak

pit will be provided around the periphery of property and designed as per
building by-law (schedule 12).
3.6 LANDSCAPE DEVELOPMENT:
Vegetation is the natural extension of the soil ecosystem on a site. It can
provide summer shade, wind protection and a low-maintenance landscape that is
adapted to the local environment. The layout masterplan is planned in such a
way that the maximum natural vegetation can be retained as is without much
disturbance. It will be further enhanced by planting additional trees as proposed

About 200 native indigenous species are planted at site. The project site has 308
existing trees (120 Teak wood, 138 Sapota, 50 Mango) out of it 193 trees (70
Teak wood, 98 Sapota,25 mango) will be retained, 115 trees will be felled (50
Teak wood, 40 Sapota, 25 mango) obtaining permission from forest cell.
Following approach will be adopted for Vegetation and Ground Management. It is
planned to include an ecologically knowledgeable landscape architect as an
integral member of the design team.
Preservation of existing vegetation, especially native plants, will possibly be
incorporated. Avoid fencing off property where possible to make landscape
available to community increasing project integration.
Decrease paving and monoculture lawns.
Avoid replacing mature trees with young seedlings.
Protect existing plants during construction. Delineate the "drip line"
around trees and demark or fence off areas to avoid damage.
Contain heavy equipment and stockpiling areas to predefined areas.
Design new plantings as diverse communities of species well adapted to
the site. Plant native species of varying ages. Select vegetation that
attracts wildlife.
Avoid invasive species and monocultures (same species, same age).

4. MANAGEMENT OF SOCIO-ECONOMIC ISSUES:
1) Schools for laborer’s children
Temporary education centers (Creche) will be provided for education of the
children of the laborers.
2) Health camp for laborer’s family
Periodical health camps will be organized to monitor and facilitate the occupants
of the labor camps.
HEALTH RISK AND DISASTER MANAGEMENT:
Public health and safety:
Since all the construction related activities are confined to the project site, minimal
health related impacts are envisaged within the project influenced area during the
construction stage.
At the project site on an average of 300 no. of persons will be engaged, who face
direct exposure to dust and noise generated from the construction activity. This is
likely to cause health related affects such as asthma, bronchitis etc., and hearing
impairments respectively.
To minimize these anticipated impacts, suitable actions like
• Use of water sprinklers to prevent dust from being air borne.
• Providing suitable Personal Protective Equipments (PPE) like mouth mask with
filters, noise mask, helmets etc.,
• Periodic health check up camp for the laborers will be arranged.
• Provision of safety belts.
• In case of injury on site medical treatment and transport will be organized.
Due to operation of the proposed project, there will be enhancement in public Health
and safety.
Regular visit of resident medical officer to take care of the first aid and
primary medication in case of emergency for project occupants and laborers.

7.0 RAINWATER MANAGEMENT PLAN:
7.1 RAIN WATER HARVESTING:
The water collected from the terraces of the buildings shall be collected in the
rainwater collection sump and reused for domestic purpose after necessary
treatment.
7.2 VOLUME OF RAIN WATER HARVESTED:
The total quantity of water i.e., received in the form of rainfall over an area is called
the rain water endowment of that area, out of which the amount of water that can be
effectively harvested is called the rain water harvesting potential.
Rain Water harvesting potential = Intensity of Rainfall (m) x Roof Area x
Impermeability Factor.
The collection efficiency accounts for the fact that all the rain water falling over an
area cannot be effectively harvested due to losses on account of evaporation, spillage
or run off etc.,
According to the data available from the Indian Meteorological Department, the
Average annual rainfall around month of September = 194.80 mm
Assuming that about 90 % Rainfall can be effectively harvested.
Number of Rainy Days = 9.3
Therefore the I.R = 194.80/9.3= 20.94 mm/day or 0.02094 m/Day or 0.021 m/day
The Quantity of roof top rainwater harvested from the proposed is calculated as
under:
The 14th floor area of the proposed project is about 6,548.55 sq m
For rain water harvesting consider 75 % of this total area is 4,911 sq m
Quantity of Rain Water that can be harvested from the building is as follows.
Rain water (Q) from Roof top = 0.021 x 4,911 x 0.9
= 92.81 cum/day or say 93 cum/day

72 PROJECT REPORT
Rain water storage sump of 100 cum (1 no) capacity is constructed to collect the rain
water and is being reused for domestic purposes.
7.3 STORM WATER MANAGEMENT:
Storm water disposal is divided into 2 Groups:
Terrace Storm water disposal: The entire rainwater from the terrace would be
disposed through suitable rain water pipes and collecting in the dedicated rain
water collection sump, which is proposed at site level. This water will be
utilized for domestic purpose
Site (Paved and landscape area) Storm water disposal: The entire storm water
from the site would be disposed off through suitable RCC Box drainage system
to the rainwater recharge pits and the excess is diverted to external storm
water drainage.
The amount of storm water that the paved area will produce can be determined by
considering the impermeability factor to be 0.9.
Q = 0.021 x 23,862.75sq m x 0.9
= 451.00 cum/day or say 451 cum/day
The amount of storm water that the landscaped area will produce can be determined
by considering the impermeability factor to be 0.3
Q = 0.021 x 16,014.69 sq m x 0.3
= 100.89 cum/day or say 101 cum/day
The Total amount of storm water = paved area + landscaped area
= 451 + 101 cum/day
= 552 cum/day
The Proponents shall also Provide Recharging Pits along the inner periphery of the
boundary wall with recharging pit of size 1.2 m dia x 2.5 m deep spaced at 20 m
centre to centre. These recharging pits are filled with graded media comprising of
Boulder at bottom and with coarse aggregates to facilitate percolation of harvested
rain water to Recharge Ground Water table.
