2.3 WATER REQUIREMENT & WASTEWATER GENERATION
There will not be any construction activity proposed as existing infrastructure is enough
for the proposed amendment. Water demand is 8.37 MLD and 5.19 MLD fresh water for
the operation phase is drawn from Hemavathi River for project needs and Industries are
not going to draw water from Tippagondanhalli reservoir.
During operation phase sewage generated will be treated in the Sewage Treatment Plant
(SBR) planned in 4.7 Ac on modular basis. The estimated Sewage generations from
domestic purpose during operation phase, 1.984 MLD. The treated water shall be reused
for toilet flushing, gardening etc. and the wastewater generated from the industries will
be treated in their respective Effluent Treatment Plants (ETP) on the basis of zero discharge
concept. The treated effluent will be reuse for industries like cooling, heat exchangers,
boilers, cleaning equipment’s etc.

Executive Summary
3.0 DESCRIPTION OF ENVIRONMENT Monitoring has been carried out at various sampling locations within the study area during
the period of 16th March 2018 to 15th June 2018. The findings of the baseline environmental
status of the land, Meteorology, Air, Noise level, Ecological Environment, Socio-economic
conditions are given below and interpreted with reference to environmental standards.
Study area of 10-km radius around the project site is shown in Figure - 1.
3.1 Meteorology
The minimum and maximum temperature for study period is 20.6°C & 34.9°C. The
predominant wind direction during study period was west followed by the westerly south
west.
3.1.1 Air Environment
The prime objective of baseline air monitoring is to evaluate the existing air quality of the
area. This will also be useful for assessing the conformity to standards of the ambient air
quality during the construction and operation of the proposed project. This section
describes the selection of sampling locations, methodology adopted for sampling,
analytical techniques and frequency of sampling. The results of ambient air monitoring
carried out in the 8 locations of the study area. The results of ambient air monitoring
carried out during the study during the month of 16th March 2018 to 15th June 2018.
a) PM2.5 – The maximum value of 34.1 µg/m3 was observed at Project Site (AAQ1). A
minimum of 17.9 µg/m3 was observed at Jolumaranhalli (AAQ7).The 24 hours applicable
limit is 60µg/m3 for industrial/residential/rural areas, the sampled locations are within the
prescribed limit

minimum of 8.52 µg/m3 was observed at Sripathihalli (AAQ6). The 24 hours applicable
limit is 80µg/m3 for industrial/residential/rural areas, the sampled locations are within
the prescribed limit. Other parameters like ammonia, ozone, CO, VOCs, Arsenic & Nickel

Executive Summary are below detectable limit. The air quality data in the monitored area within the project
site is within the prescribed limit.
3.1.2 NOISE ENVIRONMENT
a) Day Time Noise Level:-Noise levels during day time were found to be in the range
48.6 – 70.2 dB (A). The maximum noise level was observed to be 70.2 dB (A) at Project
site (N1) and a minimum of 48.6 dB (A) was observed at Birogondan Halli (N4). The
monitored locations during the Day time are under the prescribed limit.
b) Night Time Noise Levels: -Noise levels observed to fall in the range 40.3- 59.0 dB
(A) during the night time. Maximum noise level of 59.0 dB (A) was observed at Project
Site (N1) and a minimum of 40.3 dB (A) observed at Birogondan Halli (N4). The monitored
locations during the Night time are under the prescribed limit.
The Noise Level data in the monitored area near project site is below the prescribed limit
3.1.3 WATER ENVIRONMENT The water pH of groundwater samples is in the range is in between 6.72-7.84 and surface
water pH is between 7.34 and 7.91. Total dissolved solids (TDS) of groundwater samples
are 232-616 kg/ha. The total dissolved solids (TDS) of surface water samples are 121-279
kg/ ha. Correspondingly the hardness, alkalinity, chlorides & sulphates were also in
average. The groundwater and Surface water at project site is comparatively good and
with some treatment, can be used for domestic and Industrial purpose.
3.1.4 SOIL ENVIRONMENT
It has been found red sandy soil observed that the pH of the soil ranges from 6.82 - 7.54
indicating that the soil is ideal for plant growth. The nitrogen values are in the range of
284-426 kg/ha and the potassium values range between 194-346 kg/ha, which indicate
that the soils have moderate quantities of potassium. The soil from the study area shows
moderately fertility.
3.2 ECOLOGY
The flora and fauna in the study area are explored by the expert crew. The land type,
forest area and other ecological aspects are detailed in this section. The impact of the
proposed project to the biodiversity, terrestrial and aquatic ecology has been studied.
7 July 2018
Executive Summary 3.3 DEMOGRAPHY AND SOCIO- ECONOMICS
The baseline data includes the socio economic status of the area. The data about the
human settlements in and around the project site, health status of the community, existing
infrastructure facilities for social welfare, job opportunities, safety and security of the
workers and the surrounding population. The positive impact of the proposed project and
the socio economic status in the buffer zone is reported.
4. ENVIRONMENTAL IMPACTS & MITIGATION MEASURES 4.1 Air Environment
The impact on air environment depends on the raw materials of member industries. SO2
& NOX are anticipated during the usage of DG sets and boilers. The vehicles used for
transportation of raw materials will cause air pollution.
Mitigation Measures
Use of low Sulphur diesel will minimize the emission from diesel generators.
Development of green belt will reduce the level of particulate matter.
The emission standards fixed by government authorities will be followed.
Vehicles will be maintained properly.
Green belt development
Pollution abatement via green belt development is one of the vital components for any
Industrial activity. The main objectives of green belt development plan in any area are
1. Aesthetic Enhancement.
2. Reduction of impacts of air pollution and dust.
3. Arrest soil erosion
4. Climatic amelioration
4.2 Noise Environment
During operation phase, noise pollution will be aroused due to DG sets, vehicular
movements and machineries in industries. There will not be much noise during Operation
phase.
Mitigation Measures
Proper acoustic measures will be provided to reduce the noise generated by DG sets
and isolation of DG will reduce the noise at receiver’s end.
Green belt development will also reduce noise level.
8 July 2018
Executive Summary 4.3 Water Environment
During the operation phase water will be sourced from Hemavathi River. The effluent which
is supposed to be generated may cause severe problems to the environment when
compared with the wastewater generated by domestic activities. The members industries
are responsible for treating effluent from industries.
Mitigation Measures
The waste water generated by domestic activities will be treated in STP of capacity 2.0
MLD. Industrial effluents having different properties will be treated in ETP of respective
industry. KIADB will mandate member industries to adopt Zero Liquid Discharge System
as well as Rain Water Harvesting structures.
Storm water drains will be provided to collect water during rains. It would be sized
adequately to prevent flooding of the site. It is proposed to have rain water harvesting
structures for recharge of roof top rain water and rainwater of paved surface at respective
buildings. The storm water drains will be acting as recharge trench and intermittent check
dams will be provided in the storm water drains to infiltrate maximum amount of water
into the ground.
4.4 Soil Environment
Dumping of municipal and industrial waste on the land will affect the soil quality. Poor
Garbage management will lead to unsanitary conditions including vermin, odor and fly
infestation. The spillage of waste oil from DG sets will also affect the land.
Mitigation Measures
• The waste generated will be treated and disposed properly.
• Toxic waste from industries will not be disposed on land without treating it in a
proper manner.
• Generation of waste will be minimized at the source.
