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).

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.

23 SV ENVIRO LABS & CONSULTANTS| ENVIRONMENTAL MANAGEMENT PLAN
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

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
Run off Coefficient (C) = 0.8
Maximum intensity of rain fall (I) = 100 mm/hr
So, Q = (0.8 x100 x 0.46)/360 = 0.10 m3/sec
Area for catchment for open areas = 0.12Hectares
Run off Coefficient (C) = 0.6
Maximum intensity of rain fall (I) = 100 mm/hr
So, Q = (0.6 x100 x 0.12)/360 = 0.02 m3/sec

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

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.
