Sojitz Motherson Industrial Park (SMIP) Conceptual Plan 2.5 KANCHEEPURAM DISTRICT PROFILE

2.5.1 RAINFALL & CLIMATE

Kancheepuram district generally experiences hot and humid climatic conditions. The

district receives the rain under the influence of both southeast and northeast

monsoons. Most of the precipitation occurs in the form of cyclonic storm caused due

to the depressions in Bay of Bengal chiefly during northeast monsoon period. The

southwest monsoon rainfall is highly erratic and summer rains are negligible. The

normal annual rainfall over the district varies from 1105 mm to 1214mm. It is

minimum in the western and northwestern parts of the district around Uttiramerur

(1105 mm) and it is the maximum around Kovalam (1214.2 mm). High relative

humidities between 58 and 84% prevail throughout the year. Relative humidity is

maximum in the morning and minimum in the evening. Higher rates of relative

humidity are observed between November and January i.e., 83 to 84%. In the

months of June, the humidity is lower i.e., around 58%. Average relative humidity in

the morning and evening 74 and 64%. The minimum and maximum temperatures

are 20°C & 37°C. The daytime heat is oppressive and the temperature is as high as

43°C.

2.5.2 GEOLOGY & GEOMORPHOLOGY

The prominent geomorphic units identified in the district through interpretation of

satellite imagery are i) Chingleput-Tirukkalukkunram Surface (Erosional) ii) Palar

Surface (fluvial and iii) Mamallapuram (Mahabalipuram) surface (Marina) etc. The

elevation of the area ranges from 100 m amsl in the west to a sea level in the east.

The major part of the area is characterized by an undulating topography with

innumerable depressions, which are used as irrigation tanks. Three beach terraces

ranging in elevation between 4 mark the coastal tract and 12 m with broad inter

terrace depressions. The coastal plain displays a fairly low level or gently rolling

surface and only slightly elevated above the local water surfaces on rivers. The

straight trend of the coastline is a result of development of a vast alluvial plain. There

are a number of sand dunes in the coastal tract. The coastal landforms include

estuarine tidal, mud flats or lagoons and salt marsh etc.

Sojitz Motherson Industrial Park (SMIP) Conceptual Plan 2.5.3 SOIL PROFILE

Soils have been classified into 1) clayey soil, 2) red sandy or red loamy soil 3) Red

sandy brown clayey soil and 4) Alluvial soil. Of the above soils brown clayey soil is

the most predominant, covering more than 71 percent of the areal extent of

Kancheepuram district. Alluvial soils are found on the banks of Palar, Cheyyar and

other rivers. The river alluvium is transported and is seen in coastal area of this

district. Sandy coastal alluvial (arenacious soil) occurs along the seacoast as a

narrow belt.

2.5.4 GROUNDWATER POTENTIAL

The district is underlain by both sedimentary and fissured formations. The important

aquifer system in the district are constituted by 1) unconsolidated and semi

consolidated formations and 2) weathered, fissured and fractured crystalline rocks.

Porous Formation

Semi Consolidated formation:

Gondwana sandstones and shales and Tertiary mottled clays and sandstones

represent the porous, semi-consolidated sediments. Ground water occurs under

water table conditions to confined conditions in the intergranular spaces of

sandstones, sands and in the bedding planes and thin fractures of shales. The

ground water occurs under water table conditions and the depth of the wells ranges

from 5 to 10 m bgl. The depth to water level ranged from 2.89 to 4.09 m bgl during

May 2006 and 1.05 to 3.40 m.bgl during Jan’2007. The specific capacity of porus

formation ranged from 1.00 to 80.00 lpm/m/dd.

Ground Water in Unconsolidated Alluvium

These unconsolidated formations occur mainly along the banks of Palar and

Cheyyar rivers and the sand layers of this alluvium form the potential aquifer.

Between Walajabad and Kancheepuram, small diameter dug wells tap the alluvium

with depths ranging between 6 and 12 m bgl. The yield ranges from 25 to 35 m3 /hr.

Depth of filter point and dug cum bore wells ranges from 10 – 21 m bgl and yield is

around 20 m3 /hr. The yield of infiltration wells with varying depths of 5 – 12 m bgl is

around 35 m3 /hr. In areas covered by the laterites, the ground water is developed by

means of dug wells in the depth of 4 to 6 m bgl. Along the coast, windblown sand

acts as aquifer zones and ground water extraction is by means of shallow dug wells

Sojitz Motherson Industrial Park (SMIP) Conceptual Plan with radial arms. The wells can sustain for 3 to 6 hours pumping and yield is around

15 m3/hour.

Fissured Formation

The movement of ground water is fissured crystallines is principally controlled by

joints, fissured, fractures and their interconnections. Ground water in fissured

crystallines is developed by means of dug wells, dug-cum-bore wells and bore wells.

The wells range in depth between 6 and 17.00 m bgl. The depth to water level

ranged from 3.50 – 8.34 m bgl during May 2006 and 1.32 – 7.53 m bgl during

January 2007.The yield of the wells varies from 30 to 100 m3 /day (January-

March).The depth of dug cum bore wells ranges from 25 to 45 m bgl. The depth of

bore wells ranges up to 200 m bgl. The piezometric head ranges from 2.05 to 5.98 m

bgl during May 2006 and 0.70 – 3.75 m bgl during Jan 2007 and the yield ranges up

to 12 lps. The specific capacity in the fissured formation ranges from 10 - 250

lpm/m/dd.

Long Term Fluctuation (1998-2007)

The long-term water level fluctuation for the period 1998-2007 indicates rise in water

level in the area 0.0289 -0.3433 m/year. The fall in water level ranges between

0.0089 to 0.3279 m/year.

Aquifer Parameters

The Transmissivity values in weathered, partly weathered and jointed rocks vary

from 10- 125 m2 /day and specific yield in these formations is 1.5%. The specific

yield of the porus formation varied from 1.4 – 10.6%. The transmissivity in the semi-

consolidated and unconsolidated are varies from 23 to 52 m2 /day and 200 – 300 m2

/day respectively.

3.5.1.1 METHOD ADOPTED FOR THE DESIGN (MBR)

It is proposed to setup a treatment plant for treating the domestic waste, kitchen

waste adopting MBR. The MBR process is an emerging advanced wastewater

treatment technology that has been successfully applied at an ever increasing

number of locations around the world. In addition to their steady increase in number,

MBR installations are also increasing in terms of scale. A number of plants with a

treatment capacity of around 5 to 10 ML/d have been in operation for several years

now whilst the next generation. This very compact arrangement produces a MF/UF

quality effluent suitable for reuse applications or as a high quality feed water source

for Reverse Osmosis treatment.

MBR Process Description

The MBR process is a suspended growth activated sludge system that utilizes

microporous membranes for solid/liquid separation in lieu of secondary clarifiers. The

typical arrangement shown in below figure includes submerged membranes in the

aerated portion of the bioreactor, an anoxic zone and internal mixed liquor recycle.

Figure 3.4 Process Diagram of MBR

Advantages of MBR Systems The advantages of MBR include:

• Secondary clarifiers and tertiary filtration processes are eliminated, thereby

reducing plant footprint. In certain instances, footprint can be further reduced

because other process units such as digesters or UV disinfection can also be

eliminated / minimized.

• Unlike secondary clarifiers, the quality of solids separation is not dependent

on the mixed liquor suspended solids concentration or characteristics. Since

elevated mixed liquor concentrations are possible, the aeration basin volume

can be reduced, further reducing the plant footprint.

• No reliance upon achieving good sludge settlability, hence quite amenable to

remote operation.

• Can be designed with long sludge age, hence low sludge production.

• Produces a MF/UF quality effluent suitable for reuse applications or as a high

quality feed water source for Reverse Osmosis treatment. Indicative output

quality of MF/UF systems includes SS < 1mg/L, turbidity.

3.6.1.1 VERMICOMPOSTING

Vermicomposting process is an aerobic, bio-oxidation, non-thermophilic process of

organic waste decomposition that depends upon earthworms to fragment, mix and

promote microbial activity. The basic requirements during the process of

vermicomposting are

• Suitable bedding • Food source • Adequate moisture • Adequate aeration • Suitable temperature • Suitable pH

Sojitz Motherson Industrial Park (SMIP) Conceptual Plan 1. Bedding

Bedding is any material that provides a relatively stable habitat to worms. For good

vermicomposting, this habitat should satisfy the following criteria:

1. High absorbency: As worms breathe through skin, the bedding must be able to

absorb and retain adequate water.

2. Good bulking potential: The bulking potential of the material should be such that

worms get oxygen properly.

3. Low nitrogen content (high Carbon: Nitrogen ratio): Although worms consume

their bedding as it breaks down, it is very important that this be a slow process.

High protein/nitrogen levels can result in rapid degradation and associated

heating may be fatal to worms.

If available, shredded paper or cardboard makes excellent bedding, particularly

when combined with typical on-farm organic resources such as straw and hay.

2. Food Source

Regular input of feed materials for the earthworms is most essential step in the

vermicomposting process. Earthworms can use a wide variety of organic materials

as food but do exhibit food preferences (Table 3). In adverse conditions, earthworms

can extract sufficient nourishment from soil to survive. However earthworms feed

mainly on dead and decaying organic waste and on free living soil microflora and

fauna. Under ideal conditions, worms can consume amount of food higher than their

body weights, the general rule-of-thumb is consumption of food weighing half of their

body weight per day. Livestock excreta, viz., goat manure, cattle dung or pig manure

are the most commonly used worm feedstock as these materials have higher

nitrogen content. When the material with higher carbon content is used with C: N

ratio exceeding 40: 1, it is advisable to add nitrogen supplements to ensure effective

decomposition. The food should be added only as a limited layer as an excess of the

waste many generate heat. From the waste ingested by the worms, 5-10% is being

assimilated in their body and the rest are being excreted in the form of vermicast.

Sojitz Motherson Industrial Park (SMIP) Conceptual Plan 3. Moisture

Perhaps the most important requirement of earthworms is adequate moisture. They

require moisture in the range of 60-70%. The feed stock should not be too wet

otherwise it may create anaerobic conditions which may be fatal to earthworms.

4. Aeration

Factors such as high levels of fatty/oily substances in the feedstock or excessive

moisture combined with poor aeration may render anaerobic conditions in

vermicomposting system. Worms suffer severe mortality partly because they are

deprived of oxygen and partly because of toxic substances (e.g. ammonia) produced

under such conditions. This is one of the main reasons for not including meat or

other fatty/oily wastes in worm feedstock unless they have been pre-composted to

break down the oils and fats.

5. Temperature

The activity, metabolism, growth, respiration and reproduction of earthworms are

greatly influenced by temperature. Most earthworm species used in vermicomposting

require moderate temperatures from 10 – 350C. While tolerances and preferences

vary from species to species. Earthworms can tolerate cold and moist conditions far

better than hot and dry conditions. Higher temperatures (> 35oC) may result in high

mortality. Worms will redistribute themselves within piles, beds or windrows such that

they get favorable temperatures in the bed.

6. pH

Worms can survive in a pH range of 5 to 9, but a range of 7.5 to 8.0 is considered to

be the optimum. In general, the pH of worm beds tends to drop over time due to the

12 fragmentation of organic matter under series of chemical reactions. Thus, if the

food sources are alkaline, the effect is a moderating one, tending to neutral or

slightly acidic, and if acidic (e.g., coffee grounds, peat moss); pH of the beds can

drop well below 7. In such acidic conditions, pests like mites may become abundant.

The pH can be adjusted upwards by adding calcium carbonate.

3.7 POWER DETAILS

Total electric load for the proposed project is estimated at 30.32 MVA and will be

sourced through TANGEDCO. The Developer and Individual industries will be

provided back-up power based on their requirement.

3.8 RAINWATER HARVESTING & STORM WATER DRAIN

3.8.1 LOCATION OF DRAIN & NETWORK

The storm water drains will comprise of trapezoidal stone pitch. Surface water from

each catchment would be served by a network of roadside drains which would then

discharge into the proposed outlet drains.

Sojitz Motherson Industrial Park (SMIP) Conceptual Plan 3.8.2 ULTIMATE DISPOSAL OF STORM WATER

Based on the existing terrain profile, storm water falling on the existing site area

during the rainy season will flow naturally towards the Theneri Lake.

The quantity of run-off water potential for the proposed construction project is given

below.

3.10 DESIGN OF ROADWAYS

The key role of the road network in the Industrial Park is to provide smooth

movement of trucks & large vehicles. The road network will be designed based on

traffic inflow & outflow. The hierarchies of roads are as follows,


1. Primary roads – 24m wide

2. Secondary roads – 18m

3. Access to private lands – 9m

The turning radii at all junctions are considered as per IRC 41 guidelines. Multiple

locations of pedestrian crossings are provided for the convenience and locations

have been marked as per IRC 35 guidelines. Avenue plantations will be created all

along the roads. The pedestrian pathway will be shared with cycling path.

Bus stops will be located at critical points for developing an “Internal Transport

System” within the Industrial Park. These stops will also serve as lay bays to allow

emergency stoppage, break-downs, parking etc. in order to facilitate smooth flow of

traffic.

For Industrial plots, a separate entry & exit is provided so there is a loop circulation

for the trucks & trailers going into the plot for loading & unloading purposes.

The Commercial plots will have entry & exit points based on their alignment with

connecting road. The fire tender circulation to these plots will also be the same as

that for the other vehicles while the front façade of the building will be accessed by

the tender from the external road.

4.6 DEVELOPMENT OF GREENBELT

To provide a dense tree cover and to provide good sound and dust barriers, the

planting of tree species in open areas will be done. The recommended plant species

are listed in Table 4.5. As per guidelines of CPCB, the three main criteria for

selection of plants may be as follows,

Trees, shrubs will have dense foliage with a large surface area,

because leaves absorb pollutants.

The species chosen must be resistant to pollutants, particularly in

the early stages of their growth.

The species chosen may be native species and drought tolerant.
