constructed on a land admeasuring 12,256.67 Sq.mts of site area and Apartment block built up area is

37585.2sq.mts area, standing in the name of the company in Visakhapatnam. The proposed

construction will be undertaken on a plot of land after having approval of the authorities. The company

has since obtained the approval of plan and layout from the Greater Visakhapatnam Municipal

Corporation.

Project Scenario

After the adverse affects of the Economic recession in the last 1 ½ years, the construction activity,

especially construction of economy apartments and individual houses is increasing with the signs of

economic recovery. As the Directors of the company having good experience in construction activity

and acquired huge quantity of sites.

Due to the growing requirement of apartments in economy segment and to get the benefits and

privileges which were recently declared by the State and Central Governments in the form of

Government fees, flats registration charges, lower rate of interest on housing loans, income tax

benefits etc., the firm has decided to take up the construction of apartments/flats in addition to its

trading of plots/sites. Although the project is the maiden venture of the unit, it is capable of executing

the same on profitable lines riding on the collective experience and the financial strength.

WATER AVAILABILITY

Water is required for the construction as well as during occupation stage as the same is an important

resource. The Water requirement during construction is in the order of 50 cum/day with a peak demand 70

cum/day, and during occupation stage in the order of 142.2 KLD. The water resource both domestic water

and sewage is dealt by the Greater Visakhapatnam Municipal Corporation (GVMC) in the VUDA area.



Domestic water: It is proposed to draw domestic water from the Municipal Supply (GVMC), which have

been encouraging the bulk consumers. The water shortage if any during summer season will be drawn

from ground water sources. The water requirement of the project during occupation stage is in the order of

142.2KLD. The water requirement during construction will be from ground water sources and the

requirement is in the order of 50 cum/day.

The Environmental Management Plan envisaged for this construction project is described hereunder

with a strong commitment to follow best Environmental practices to reduce the negative implication to

make this project a sustainable development endeavor.

The management action plan aims at controlling pollution at the source level to the possible extent

with the available and affordable technology followed by treatment measures before they are

discharged.

Environmental management plan aims at the preservation of ecosystem by considering the pollution

abatement facilities at the project inception. In the upcoming modern housing project, pollution

abatement has become an integral part of planning and designs along with techno economic factors.

The different Environmental components that are identified in the assessment chapter are dealt

hereunder with necessary environmental management plan. 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.

Following sections describes the environment management plan proposed for construction and

operation phases.

1. SITE CLEARANCE:

Control of Soil Erosion:

Generally cutting of herbaceous vegetation, during the construction phase results in the loosening of

the top soil.

Vegetation removal shall be minimized to prevent extent of soil erosion.

Vegetative cover shall be re-projected /rehabilitated at the earliest practicable time to minimize

duration & extent of soil erosion.



Control of Noise Levels:

Selection of equipment with less noise generation to be used.

The earth moving equipment shall be periodically checked and maintained for noise levels.

Since the site is more or less even use of these earth moving equipments may not be necessary.

The workers shall be provided with adequate personal protection equipment (PPE) such as ear

plugs to reduce impact of high noise levels.

Control of Dust generation:

The construction activity will result in the increase of SPM concentrations due to fugitive dust.

The site cleared shall be periodically watered to reduce emission of dust particles.

The workers shall be provided with PPE such as nose masks and goggles to reduce impact

on health.

2. AIR ENVIRONMENT:

As the proposed unit is a construction of an apartment, SPM, SO2 & NOX emissions from the

operations will be very less concern. Water sprinkling will be provided through out the complex to

control the fugitive emissions arises if any during construction activity.

Generation of Dust

Pre Construction & Construction Stages

Dust will be generated from transport, construction, and utility operations. The mitigative measure

proposed is water sprinkling of the roads, and covered construction activity so as to ensure the dust

does not fly. The road condition is a major cause of the dust and permanent black top roads will be

provided as far as possible in the construction area. Exposure of labor and employees during

construction will be mitigated by provision of facemasks to employees at dust generating sources.

To reduce level of dust emissions from the crusher and batching plant and other transportation of

materials will be taken up including vehicles delivering loose and fine materials like sand and fine

aggregates shall be covered to reduce spills on existing roads. Water will be sprayed on earthworks,

temporary haulage and detour roads on a regular basis.

During and after compaction of the sub-grade, water will be sprayed at regular intervals to prevent

dust generation. The dust emissions from the vibrating screen at the stone quarries do not exceed the

emission standards set by CPCB by providing covered areas and adopting water sprinkling.



Occupation Stage

The residential area will have greenery and all roads shall be paved and all slopes & embankments

shall be turned as per best engineering practices.

3. WATER ENVIRONMENT Water consumption for the Residential is estimated to be about 142.2 m3/day. The wastewater

generated from the domestic usage will be about 127.98m3/day only. Sree Balaji Nirman & Estates

proposes to build a full-fledged Sewage Treatment Plant and treated water will be used for green belt

development/toilet flushing.

The sewage generated from all the flats will be collected through the network of drains. The collected

sewage will be routed to the sewage treatment plant through covered drains provided with inspection

chambers.

The treated sewage will be used pumped into the overhead flush water tanks for flushing of toilets in

all Residential units and part of the treated water will be used for green belt development through

closed pipelines.

4. NOISE ENVIRONMENT & GROUND VIBRATIONS

The major noise levels will be confined to the construction activity while handling concrete mixer and

other consumables. The Leq of eight hours will be within the prescribed standards. Community noise

levels are not likely to be effected due to the proposed green belt development and attenuation due to the

physical barriers.

Construction Stage

The plants and equipment used for construction will strictly conform to CPCB noise standards. Vehicles

and equipments used shall be fitted with exhaust silencers. During routine servicing operations, the

effectiveness of exhaust silencers shall be checked and if found to be defective shall be replaced. The

noise level from any item of plants. Such as compactors, rollers, front loaders, concrete mixers, cranes

vibrators and saws shall not exceed 75 dB (A), as specified in the Environmental Protection Rules,1986.

The construction activity within 150 m of the nearest habitation, noisy construction work such as concrete

mixing will be restricted to daytime and there will not be any construction during the nighttime between

9.00 pm and 6.00am. To protect construction workers from severe noise impacts, noise standards of

industrial enterprises will be strictly enforced, and workers shall be provided with personal protection

Equipment (PPE).



Occupation Stage

The residential areas adjacent to the proposed 40 feet and Existing 20 feet wide roads will be checked for

noise levels and based on the results additional mitigation measures will be taken up like double-glazing

of windows if necessary.

The major sources of noise are DG sets

DG set will be housed in an area where the access will be restricted.

Acoustic dampeners in foundations and insulators in the interiors will be provided.

Personnel operating DG sets will be provided with ear muffs.

Selection of equipment to ensure that the residual noise level of 75 dB (A).

Noise levels will be checked periodically using a noise pressure level meter.

5. STORM WATER DRAINS AND RAINWATER HARVESTING:

A well connected isolated storm water drains has been designed to collect the rainwater from the entire

residential project. The design of the storm water drainage is based on the worst rainfall of max

100mm/hr.

RAINWATER HARVESTING PIT:

The collected storm water will be routed to the proposed rainwater harvesting pits at respective tower

for recharge of the ground water.

6. LAND ENVIRONMENT

The study area is predominantly agriculture oriented. Crops like paddy and coconut crops are

predominantly cultivated in the surrounding vicinity. The main source of water is ground water. The

soils in the area are predominantly clay with high fertility.

Design and Construction stage

The mitigation measures proposed to maintain the physiographic undisturbed or impacted to the

minimum is to maintain the contour levels and to keep the higher contour levels undisturbed. The

lowest levels of contour are undisturbed and are used for construction of high – rise structures. It may

be observed from the cut and fill operation is to use machinery and tippers which have pollution under

control certificate is to use machinery and tippers which have pollution under control certificate, using



water sprinkling of the cut and fill areas, and ensure that natural drainage is not filled with cut

material.

Occupation stage

The change in the physiography of the project site is enhanced by greening program of the central

area.

7. SOLID WASTE GENERATION:

Solid waste generation from the proposed residential project is in the following ranges:

Municipal solid waste - 523 Kg/day

Sludge from STP - 10 Kgs/day

PROPOSED SEWAGE TREATMENT SYSTEM

Based on the literature available and after study of wastewater characteristics the following treatment

system has been designed.

I. PRIMARY TREATMENT

Bar Screen chamber

Grit Chamber

Neutralization tank cum Equalization tank

II SECONDARY TREATMENT

Aeration tank

Secondary clarifier

Clarified Water storage tank

Sludge holding tank

Filter Press

III TERTIARY TREATMENT

Sand filter

Activated Carbon filter

Treated water storage tank

IV MODE OF DISPOSAL

The wastewater after treatment will be used for development of Green belt/toilet flushing /sewerage

system.



TREATMENT SCHEME PRIMARY TREATMENT

BAR SCREEN CHAMBER

Screen is the very first operation carried out at treatment plant, and consists of passing the wastewater

through screens, so as to trap and remove the floating matter, such as pieces of paper, wood, cork, hair,

fiber, etc., present in wastewater. These floating materials if not removed, will choke the pipes, or

adversely affect the working of the pumps. Thus the main idea of providing screens is to protect the

pumps and other equipments from the possible damage due to the floating matter.

Bar screens are provided with an inclination of 300-600 to the direction of flow. Large floating matter is

obstructed by these screens. The screens are to be cleared frequently by manually to allow free flow of

wastewater in to the treatment system.

GRIT CHAMBER

The waste water came from the bar screen chamber flows into the grit chamber where the solids will be

collected and clear wastewater flows to the final collection tank for further usage.

EQUALIZATION/NEUTRALIZATION TANK

The wastewater varies widely in its characteristics both qualitatively and quantitatively and hence to

equalize the waste water air flow line is provided. At this stage the pH value should be maintained in

between 7.5-8.0.

SECONDARY OR BIOLOGICAL TREATMENT

CHEMISTRY OF BIOLOGICAL REACTION

The coagulation of non – settleable collection solids and the stabilization of organic matter contributing to

BOD are reduced by principally by bacteria. The microorganisms convert the colloidal and dissolved

carbonaceous organic matter into various gases and into cell tissue. Because cell tissue has a specific

gravity slightly than water the resulting tissue can be remove from the liquid by gravity setting.

The converter of organic matter into gaseous end products and cell tissue can be accomplished

aerobically. An aerobically or facultatively suspend growth or attached growth system. In aerobic

conversion apart of the organic matter is converted to end products and other part to obtain the energy for

the synthesis of new cells and hence the growth.



In most biological treatment systems, these three processes occur simultaneously in the activated sludge

process, the bacteria are the most important microorganisms, because they are responsible for the

decomposition of organic materials in the influent. In the reactor, or mixed reactor, or mixed liquor tank, a

portion of the organic waste matter is used to obtain energy for the synthesis of the remainder o f he

organic material into new cells.

While bacteria are the microorganisms, that actually degrade the organic waste in the influent, the

metabolic activity of other microorganisms is also important in the activated sludge system.

For example protozoa and rotifers act as wastewater polishers protozoa consumes dispersed matter that

have not flocculated and rotifers consume small biological flocculated particles that have not settled.

AERATION TANK Supernatant from the Primary clarifier over flows in to the aeration tank where the organic matter in the

wastewater is biologically decomposed under aerobic conditions. The mixed liquor in the tank is aerated

by using 1 no. slow speed diffused aerator. The MLSS in the aeration tank is maintained around 4000 mg/l

by return sludge, dissolved oxygen of 1 to 3 mg/l has to be maintained. The detention time in this tank is

around 6 hours. The mixed liquor from this tank over flows into the secondary clarifier.

SECONDARY CLARIFIER

The mixed liquor from the aeration tank overflows into the lamella clarifier. Here the wastewater is kept

under comparatively quiescent condition. This allows the solids from mixed liquor to settle. The mixed

liquor enters the drum of the clarifier at the center and distributes itself equally of all ides. It leaves

through the periphery of the tank. The wastewater moves very slowly facilitating setting of sludge at the

bottom as specific gravity of sludge is higher than that of water. The required amount of sludge is recycled

and the rest is bleeded out.

SLUDGE FILTER PRESS

Hydraulically operated filter press will be installed with 12 nos. of plates to dewater and cake will be used

as manure.

SAND FILTER AND CARBON FILTER The wastewater from secondary clarifier over flow into sand filter where any traces of organic matter will

be removed. Further, the effluent overflow in to activated carbon filter, there the wastewater will be



treated by the principal adsorption and removes partially total dissolved solids. The clear supernatant will

be sent to polishing pond for recirculation into process or to use for Green belt development

It is proposed to release / dispose the storm water in the storm water drains.

STORM WATER DRAINS

Conservation of water resource is most important aspect of the project during construction and occupation

phases. Storm water drainage planning, domestic water planning and sewage transfer and sewage

treatment planning are critical aspects of construction and occupation stages of housing projects.

Storm water drains will be provided all over the site to meet the expected increase in the runoff during

rainy seasons due to the impervious nature of the paved areas. The site is uneven and it is proposed to

maintain the levels as much as possible, hence storm water outlets from the storm water runoff and

presented in following table.

It is proposed to release / dispose the storm water in the storm water drains.

CALCULATION FOR STORM WATER DRAIN

Quantity of storm water:

(a) Without project

Discharge (Q) = (C x I x A)/360

Area of Catchment (A) = 12256.67 sq.mts. = 1.22Hectares

Run off Coefficient (C) = 0.6

Maximum intensity of rain fall (I) = 100 mm/hr

So, Q = (0.60 x100 x 1.22)/360 = 0.20m3/sec

(b) With project

Discharge (Q) = (C x I x A)/360

Area for catchment for roof area = 0.46 Ha

Area of Catchment (A) = 0.46 Hectares



So, Q = (0.8 x100 x 0.46)/360 = 0.10 m3/sec

Area for catchment for open areas = 0.12Hectares



So, Q = (0.6 x100 x 0.12)/360 = 0.02 m3/sec



Total Discharge = 0.12 m3/sec

Discharge (Q) = A/V

Where

A = Area of the Drain

V = Max. Permissible Velocity

= 3.0 m/sec for concrete drain

Area of drain (A) = Q/V

= 0.12/3 = 0.04 m2

Taking depth of the drain as 0.3 m at the starting point

Width of drain = Area/depth = 0.04/0.3 =0.13m = 13cm

Width of the drain is to taken 105cm and depth varies according to the slope of ground.

Housing project will have traffic entry / exit from the existing road connecting to NH-5

road. The entry/exit points have been marked on the layout plan.



GREEN BELT DEVELOPMENT

Green belt has been developing all around the housing project. About 2 m wide all around

the proposed project has been provided for development of trees in two rows. The design of

the greenery will be done in consultation with the horticulturist.

The selection being based on the broad-leafed nature of the trees and its ability to attract

birds.

The philosophy behind the green belt development is to improve the ecology and

environment of the surrounding of the plant by extensive afforestation.

Planting scheme has also been chosen keeping in mind the needs of residents during

traditional/festive occasions apart from functional, ecological and aesthetic needs.

PLANT DETAILS

Greenbelt is a set of rows of trees planted in such a fashion, to create effective barrier

between the project and surroundings. The greenbelt helps to capture the fugitive

emissions, attenuate the noise levels in the housing project and simultaneously improving

aesthetics of the housing project. The greenbelt around the housing project compound wall

and in the reserve site will be developed in keeping view of the following objectives.

1. Planting of trees in each row will be in staggered pattern.

2. The short trees will be planted in the first two rows and the tall trees in the outer

rows around the purview of the project site.

3. Since the trunks of the trees are generally devoid of foliage, it will be useful to have

shrubs in front of the tress so as to give coverage to this portion.

4. Sufficient spacing will be maintained between the trees to facilitate effective height

of the greenbelt.

5. Plants of native origin, fast growing type with canopy and large leaf index shall be

preferred.
