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.

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

below:

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).

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.

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


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


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.
