7.0 SEWAGE GENERATION
Construction phase:
Quantity of sewage generated during the construction phase will be negligible and
proper management will be done by providing mobile toilets. Septic tank & soak pit
will be provided on site for treatment.
Operational Phase:
Sewage generated during operation phase would be approx. 606 KLD. Capacity of
onsite STP is 730 KLD.
8.0 SOLID WASTE GENERATION, COLLECTION, TRANSPORT AND DISPOSAL
Solid waste would be generated both during the construction as well as during the
operation phase. The construction waste expected to be generated during the
construction phase will comprise of soil, sand, gravel, bricks, concrete, bitumen wood
and other materials. The following steps are to be followed for the management solid
waste:
• Construction yards are used for storage of construction materials.
• The excavated material such as topsoil and stones will be stacked for reuse during
later stages of construction.
• Excavated top soil will be stored in temporary constructed soil bank and will be
reused for landscaping of the Project.
• Remaining soil will be utilized for back filling / road work /rising of site level at
locations.

PVT. LTD
PLAN
• Brick parts and broken concrete will be used as cinder filling.
• Unusable waste will be sent to CD site through authorized agency.
Waste generation during Operation Phase

Treatment of Bio-Degradable wastes
Biodegradable /Organic and Horticultural Waste would be treated in Organic Waste
Converter installed at site. Generated compost would be used as manure for
horticulture development.
Non Biodegradable waste
Recyclables, such as plastic, rubber, wood pieces, glass etc will be segregated from
non biodegradable waste & sold to authorize vendors for recycling & remaining inert
waste shall be sent to land fill site through authorized vendor as per the guidelines of
Municipal Solid Wastes (Management and Handling) Rules, 2000 and amended
Rules, 2016.

Based on the tectonic features and records of earthquake, a Seismic Zoning map has
been developed for the country by Bureau of Indian Standard (BIS). The area under
study falls in Seismic Zone-IV. Suitable seismic coefficients in horizontal and vertical
directions respectively, will be adopted while designing the structures. Earthquake
resistant construction material will be used.
15.0 EMERGENCY LIGHTING
The emergency lights operated on DG sets/battery power should be provided at
appropriate locations – such as corridors, common area, staircase, exit and entrance
doors, parking, etc. The transformers will be kept energized and should feed
independently alternate rows of lights so that in case of failure of one transformer,
there will not be complete darkness.

PLAN
16.0 FIRE SAFETY
In design component of the project, adequate measure has being taken as per the
provisions of the National Building Code to provide for fire protection services. Required
quantity of water will be stored within the premise to subdue fire if at all required. Water
will be supplied from the underground and overhead water storage reservoir. Apart from
providing sufficient water for firefighting, other measures that have been considered
include:
The internal roads will have sufficient load bearing capacity to withstand fire engines
The building materials shall be of appropriate fire resistance standard. Further,
design shall include provision for the following:
o The electrical systems shall be provided with automatic circuit breakers activated
by the rise of current as well as activated by over current.
o Fire Alarm systems at appropriate places
o Means of escape,
o Access for fireman
o Adequate fire fighting requirement have been taken into account while designing
the electrical distribution system.
17.0 ENVIRONMENTAL POLLUTION MITIGATION MEASURES
17.1 Air Pollution
Increased traffic generation due to project (no. of parking space proposed for the
project is not going to cause significant increase in atmospheric concentration of gases
and will not result in heat island formation as adequate landscaping has been provided.
Mitigation Measures for Air Pollution during Construction Stage
Air quality around the project site will be impacted during construction stage. Various
construction activities especially related to handling of loose material are likely to
generate fugitive dust that will affect the air quality of the surrounding area of the project
site. To minimize such impacts following measures has been proposed:
All the loose material either stacked or transported will be provided with suitable
covering such as tarpaulin, etc.
Water sprinkling shall be done at the locations where dust generation is anticipated.
To minimize the occupational health hazard, proper personal protective gears i.e.
mask shall be provided to the workers who are engaged in dust generation activity.
Mitigation Measures for Air Pollution during Operational Stage
Operation of DG Sets is the only source of air pollution during operational phase.
Sufficient stack height will be provided for proper dispersion of pollutants. Also, it is
proposed to minimize air pollution by providing plantation as buffer on the periphery of
the project site and on the open spaces. An area of 7282 m2
(14.5% of the Plot Area)
has been kept for landscape/green development.
17.2 Water Pollution
The source of water pollution during construction and operation phase is due to waste
water generated from toilets and washing.
Mitigation Measures for Water Pollution during Operational Stage:
Waste water generation and treatment and reuse are dealt in 6.1.

PVT. LTD
PLAN
17.3 Noise Environment
During construction the machineries used were of highest standard of reputed make
adhering to stipulated standard. Hence, insignificant impacts due to construction
machinery are envisaged. Apart for this, the construction activities were restricted to day
time only.
Source of noise for the existing as well post construction phase are from the material
handling operations and utility units like cooling tower and DG sets. The DG sets are
operated during power failure only and provided with inbuilt acoustic enclosure as per
CPCB standard.
Mitigation Measures for Noise Pollution during Construction Stage
During the construction stage, expected noise levels shall be in the range of 80-85 dB
(A) which will decrease with increase in distance as per the Inverse Square Law.
Administrative as well as engineering control of noise will be implemented. Isolation of
noise generation sources and temporal differentiation of noise generating activities will
ensure minimum noise at receiver’s end. To prevent any occupational hazard, ear muff /
ear plug shall be given to the workers working around or operating plant and machinery
emitting high noise levels. Use of such plant or machinery shall not be allowed during
night hour. Careful planning of machinery operation and scheduling of operations shall
be done to minimize such impact.
Mitigation Measures for Noise Pollution during Operation Stage
It is envisaged that there shall be maximum movement of light motor vehicles like cars
which will lead to some increase in noise levels. It is proposed to minimize the noise
levels by providing plantation as buffer on the open spaces and around the periphery of
whole complex. Informatory signboards shall be provided to encourage vehicle owners
to maintain their vehicle, not to blow horns and follow the emission standards fixed by
Government Authorities
DG sets will be kept in the acoustic chamber and ambient noise will be within the CPCB
standard limits.
18.0 CONSTRUCTION MATERIALS
Following construction materials are required for construction of Institutional Building:-
1. Coarse sand
2. Fine sand
3. Stone aggregate
