Preamble:

INVESTIGATION METHODOLOGY &

TEST RESULTS

CHAPTER-2

Eight soil investigation boreholes were put as per the planning of the engineer in-charge and

these locations are shown in Fig.2.0.The equipment used and the methodology adopted to

carry out the fieldwork is described below.

Scope of Drilling:

The drilling depth of 12.0m below E.G.L was recommended by M/S. K RAHEJA CORP PVT

LTD, irrespective of the characteristics of the strata encountered.

Methodology of Field Work:

Equipment Used and Method of Drilling:

All the boreholes were sunk by conventional rotary drilling rigs. For borehole Methodology

followed for boring conformed to IS: 1892 -2000. Boring was progressed by the cutting action of

rotating bit with water circulation and stabilizing the side of the boreholes by using casing

pipes/bentonite slurry up to required depth to prevent collapse of sidewall. Boring was

continued by normal boring process using MS soil cutter in soil. However Tungsten Carbide

(TC) bit drilling was resorted to drill in highly weathered rock stratum where the normal boring

process became slow. Diamond Core (DC) bit drilling was adopted in moderately weathered

rock formations where penetration using TC bit was became slow.

Standard Penetration Tests:

This is a field test to determine “Penetration Resistance of Stratum at the Test Depth”. This has

been conducted in the boreholes generally up to refusal depth using procedures described in

IS: 2131- 2002. In this test, split spoon sampler (50.8 mm OD and 35 mm ID) has replaced

driving bit. Sampler is then driven by dropping 63.5 kg hammer on top of driving collar with free

fall of 75 cm. The length of sampler is 60 cm.

The tests were conducted at the depth intervals indicated in Chapter-1 (Sec.1.1.1).

Collection of Soil Samples:

2.2.3.1 Disturbed Samples:

The SPT-samples collected were used as disturbed soil samples. These samples were used for

visual and physical identification and for conducting laboratory classification tests as per

I.S.1498-1970.

Collection of Ground Water Samples:

One representative water Sample from each borehole was collected after 24 hours of

completing the borehole.

Laboratory testing:

On Coarse Grained Soil

On the representative samples, sieve analysis tests were conducted to arrive at grain size

distribution. These tests were conducted as per I.S.2720 (part 4)-1985 and the results are

presented in Tables-2.1 to 2.8. The grain size distribution is presented in Fig. 2.10 to 2.17.

On Fine Grained Soil

On the SPT sample index property tests were conducted to estimate consistency. These test

results are presented in Tables-2.1 to 2.8. The hydrometer analysis is presented in Fig. 2.18 to

2.25.

Chemical Analysis Tests

On representative soil samples chemical analysis tests were conducted to estimate pH,

Chloride and Sulphates and these results are presented in Table - 2.9.

Summary:

The locations of the field investigation boreholes are shown in site plan given in Fig.2.0. The

average sub soil profiles encountered at each location along with their classification and

engineering properties are presented in Figs.2.1 to 2.8. Further, the cross sectional variation of

the sub surface profile through different bore holes is presented in Figs.2.9.

CHAPTER-3

SUB-SURFACE STRATIFICATION

Preamble:

The sub surface stratification at borehole location, with respect to Foundation/Geotechnical

Engineering Application are derived based on the visual identification, laboratory classification

tests and field insitu strength tests. Further, the strength parameters are estimated based on

the in-situ strength test results as per the following correlations.

Design Sub Soil Profile:

The sub soil characteristics obtained at the test location are further processed to arrive at the

design soil parameters required for the design of sub structure using the following shear

strength correlations with respect to the Standard Penetration Test Values of different layers.

For Coarse Grained Material, Ref. IS: 6403 to estimate Angle of Shearing Resistance

(Reproduced and shown in Fig.A1)

For Fine Grained Material, Ref. Terzaghi & Peck, 1948, to estimate Unconfined

Compressive Strength (Reproduced and shown in Fig.A2)

Based on the above, the average design soil characteristics are given below:

Preamble:

FOUNDATION SYSTEM

CHAPTER-4

In the design of foundation system, the stress-strain compatibility of the super structure, sub

structure and the bearing strata should be satisfied both individually and as a combined

system. In view of this, the following data are needed for the design of foundation system,

defined in terms of the type of sub structure and the bearing strata characteristics.

The super structure characteristics along with the loading pattern on the sub structure

The sub soil characteristics that define the required substructure configuration for a

safe transfer of super-structural loads to the bearing strata

Considering the above aspects of the foundation design, the suitable type of foundation

system is presented below.

Proposed Structures

The proposed structure is a MSB IT/ITES PARK commercial building consisting of

1 Basement Lower Ground + Stilt + Upper Stilt 1, 2, 3 + 13 Floors.

Foundation System:

For the kind of proposed configuration of structure, sub soil conditions shallow foundation

system shall be adopted and the basement clear height of about 6.0m from the existing

ground level, as informed by the client in charge during the time of preparation of report.

The recommended allowable bearing pressures of different sizes of footing with different

embedment lengths in rocky formation are worked out and presented in table-4.1.

Typical computations are presented in annexure.

Since the sub soil stratum below the founding level is rock with varying grade of weathering

only immediate elastic settlement will takes place.

CHAPTER-5

RECOMMENDATIONS

Recommendation for Foundation:

For the kind of sub soil conditions isolated column footings as discussed in Chapter-4 can be

adopted.

During monsoon season, open dewatering may be adopted.

The recommended allowable bearing pressures of different sizes of footing with different

embedment lengths in rocky formation are worked out and presented in table-4.1.

Since, chlorides and sulphates are well within the permissible limits, no special steel or

cement is required for the construction of footings.

Recommendation for Excavation:

For carrying out the deep excavation, the sides can be retained by installing contiguous bore

cast insitu pile taken for a minimum depth three times the diameter of pile into underlying hard

rock, which is encountered beyond 10.0m to 11.0m and duly anchored with passively pre-

stressed rock anchors.

For the kind of rock profile excavation from 6.0m to 11.0m no blasting is required and

convention excavators can be used, however, for excavator from 11.0m to 12.0m,

conventional excavator fitted with rock breakers may be required.

Though the soil in the excavated depth is clayey in nature, the strata beyond 6.0m being

completely weathered rock, it is ideal to provide deep bore wells of 15.0m deep in a 20.0m

grid and lower the water table to the bottom of excavation.

Optional

The efficiency of excavation in the top very soft clay can be improved by increasing the

consistency of the clay. For increasing the consistency, sand-lime columns of 200mm

diameter spaced in a grid of 1.0m and 4.0m deep can be used. However, this

recommendation is a guide line and can be used, subject to site experience while carrying out

the excavation in the soft clay.

2 Computation of Settlement: (as per IS:8009-Part-I-Ref. Eq.11)

2.1 Elastic Settlement (Se)

Since, the bearing straata are weathered rock, for the prupose of computing the settlement, which will be of

elastic type, the weathered rock is modeled as coarse graiend sand and accordingly, the Es is estimated

using SPT-value correlation. Further, to estimate the maximum settlement, the maximum size of footing is

considered as 6.0m.

The immediate elastic settlement (Si)= qB(1-m2)*I/Es

q= bearing pressure 1500.00

Poission's Ratio (m1) 0.20

Modulus of Elasticity (Es)(Ref. Joseph E Bowels,1996,page316,Table5.6, Japanese

design standards)

Modulus of Elasticity (Es) 156000.00

DESIGN DETAILS

Rain water harvesting technique has been adopted as per NBC Part-9, 5.5.12.1

The rational method is to be preferred to calculate the Storm water run-off.

Q = Runoff in m3/sec

I = Intensity of rainfall in mm/ hr.

A = Drainage area in hectares.

C = Co-efficient of run off as below

Run-off co-efficient for various types of surfaces

Open grounds, unpaved street 0.30

Parks, lawns, gardens 0.20 to 0.50

Macadam roads, pavements 0.70

Asphalt pavements 0.85 to 0.70

Water tight roof surface 0.95

Total Run-off : ROOF TOP

Q = Runoff 0.323 m3/sec

I = Intensity of rainfall 79 mm/hr

A = Drainage area in hectares. 1.55 Ha

C = Co-efficient of run off 0.95

Data assumed:

Considering 15 min of rainfall

Volume of rainwater available for harvesting is 291 Cum

This run-off is being diverted to roof top rain water collection sump, which

shall be used for domestic purposes after the necessary treatment.

Rain water recharging technique has been adopted as per NBC Part-9, 5.5.12.2

Total Run-off : PODIUM AREA / HARDSCAPE & DRIVEWAY





Data assumed:


Volume of rainwater available for recharging is 95 Cum

Date : 25.06.16

Project : Raheja IT park at Pallikaranai, Chennai

To supplement the ever growing shortage of protected, pure and safe water supply for

human consumption rain water is an ideal source which can be conserved and used in a

useful manner by the people.

Rational formula for calculating runoff = Q = (C I A) / 360

It is essential to catch the runoff and use it for augmentation of ground water reservior

by modifying the natural movement of surface water by recharging it by artificial means

for example, construction of recharge structures.

86/4, door no.2, Pallavaram Thoraipakkam Radial Road, Pallikaranani village, Sholinganallur

Taluk, Kancheepuram District , with a view to conserve fresh water resources and adopt re

cycle and re-use measures. They propose to set up a water pollution control and re-use

system for the wastewater generated from entire campus and also proposed to harvest and

recharge ground water as storm water management. The only source of waste waters is

from toilets, kitchens/pantries and wash basins and washrooms etc in the campus and

therefore domestic in nature.

This report details the following from the proposed facility: Collection, Treatment and

Disposal of Domestic Effluents.

2) QUANTITY AND QUALITY OF WASTEWATERS

For commercial unit with a population of 32,139 souls and average water consumption

considered for design is 45 LPCD.

The wastewater quantity from domestic sources is considered at maximum of 90% of water

consumed. Hence the quantity of wastewater generated is as below,

a) Quantity of wastewater flow for STP = 600,000 Lit/day for Block-01

b) Quantity of wastewater flow for STP = 350,000 Lit/day for Blocks-02

c) Quantity of wastewater flow for STP = 350,000 Lit/day for Blocks-03

Treatment plant for treating sewage in the campus has been proposed for a capacity of 600cum/day, 350cum/day & 350cum/day.

3) CHARACTERIZATION

The general characteristic of sewage is considered as shown in the table below.

General characteristics:

pH : 7 – 10

BOD : 250 – 350 mg/L

COD : 500 – 600 mg/L

user

Typewriter

138

SS : 150mg/lt.

The anticipated final water quality:

pH : 6 – 9

BOD : < 20 mg/L

COD : < 60 mg/L

SS : < 30 mg /L

TSS : < 10 mg/L

Residual Chlorine : > 1.0 mg/L

E.Coli : Nil

4) MODE OF TREATMENT

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

adopting Mixed Bed BIo Reactor using diffused aeration. The other modes of treatment

considered before arriving at activated sludge process are FAB (Fluidized Aerobic Bio

Reactor), ASP (Activated Sludge Process), SBR ( Sequencing Batch Reactor) etc. The

advantages and disadvantages of the each scheme, initial investment and maintenance cost

etc were compared and finally arrived at providing a STP using MBBR – Mixed Bed Bio

Reactor.

The units proposed for the proposed STP with MBBR are:

SL. No.

Name of the Unit

Purpose

1 Bar Screen Chamber For removing unwanted floating materials.

2 Equalization Tank To even out the flow variations and continuous uniform

mixing operations with course bubble.

3 Anoxic Tank For BOD reduction under anoxic conditions

4

MBBR Reactor

Activated Sludge Process for developing the bacterial

culture, which stabilizes the waste using submerged

diffusers. The reactor is provided with floating media which acts as an attached growth media for the enhanced

growth of biological organism

user

Typewriter

139

5

Settling Tank

The settling tank / clarified water tank acts as secondary

settling tank for settling the floating solids and activated

sludge which escapes out of the MBBR reactor. It also acts

as concentrator for the return activated sludge

6

Clarified Water Tank

The clarified water tank / pre-filtration tank is a storage

tank for collecting the over flow supernatant from the settling tank. From this tank the treated water is fed into

the Sand Filter and Carbon filter for further polishing and

treatment

7 Pressure Sand Filter To filter out suspended solids if any in the treated water.

8 Activated Carbon Filter To remove color and Odor if any in the filtered water.

9

Chlorinator

To disinfect the treated water to make it safe to come in contact with humans so that the treated water can be

used for gardening / allied uses.

5A) METHOD ADOPTED FOR THE DESIGN

The Sewage Treatment Plant is designed MBBR (Mixed Bed Bio Reactor). The system is

designed for a continuous operation scheme on a 24 x 7 basis.

b) DESIGN OF THE INDIVIDUAL UNITS

Bar Screen Chamber:

Provide a chamber of size 1.0 m x 0.60 m to suit sewer gradient to accommodate an

inclined bar screen with opening less than 10 mm. Provide a bar screen of 20 X 6 mm flats

with 10mm spacing in between as coarse bar screen and provide a 1.0 m x 0.60m bar screen

with 10mm sq openings as a Fine Bar Screen.

Equalization tank:

The flow from the bar screen chamber is let into the equalization tank. This tank is

provided to even out the flow variation, and to provide a continuous feed into the

secondary biological treatment units.

Design flow = 600,000 Lit/day

Average flow = 20 Hours

Provide Equalization Tank with a HRT of 6 Hours (holding capacity)

Hence required volume of the tank = 180.00 m3

Provide a tank of 180,000 Lit. Capacity.

The tank size would be 72sqm x 2.5m (effective volume)

Anoxic Tank:

Flow = 600 KLD.

Average Flow = Plant Capacity / 20 hrs

30 m3/hr

HRT = 2.5 Hours

Volume of Anoxic Tank = 75.0 m3

Hence provide an anoxic tank with a volume of ~ 75 m3

The tank size would be 18.75 sqm x 4m (effective volume)

MBBR Tank:

Flow = 600 KLD.

MLSS = 5000 mg/L

Food to Mass ratio ( F/M) = 0.135

Total BOD in Kg/day = (BOD in mg/L x Plant Capacity) / 1000

Total BOD in Kg/day = 210.0 kg/day

user

Typewriter

142

Volume of Aeration Tank = Total BOD / ( MLSS x F/M Ratio)

= 311.1 m3

Hence provide an MBBR tank with a volume of ~ 315 m3


Calculation of Air Volume

"BOD5 after treatment <10 mg/lit

"BOD5 Loading = 350 mg/lit

"Total BOD5 load = 600 x 1000 x 350kg/day

1000000

"Total BOD5 load = 210 kg/day

BOD5 load in Kg/day in the aeration tank = 210 Kg

Oxygen required in Kg/day = 420 kg/day

(2 kgs of Oxygen is required for every Kg of BOD5 to be removed)

% of Oxygen in air = 0.21

Density of air = 1.2

Air Volume required per day = 1667 m3 of 02 / day

No. of hours of oxygenation = 18

= 92.6 m3 / hr

Diffuser Transfer efficiency = 92.6/0.18

(18 % for 4.5m submergence after providing for media loss)

= 514 m3 / hr

Hence, Air volume required in Aeration tank = 514 m3

/ hr

Consider 30% extra for equalization tank = 669 m3 / hr

Total Air Volume required = 670 m3 / hr

Therefore Total air requirement in Cum. / Day = 670 m3 / hr

Secondary Clarifier :

Plant Capacity = 600 KLD

Loading Rate = 25 m3/sqm/day

Volume Considered in Design = 2 times plant capacity

Surface area of settling tank = Plant Capacity x 2 / Loading Rate

Surface area = 35 m2

secondary biological treatment units.

Design flow = 350,000 Lit/day

Average flow = 20 Hours

Provide Equalization Tank with a HRT of 6 Hours (holding capacity)

Hence required volume of the tank = 105.00 m3

Provide a tank of 105,000 Lit. Capacity.


Anoxic Tank:

Flow = 350 KLD.

Average Flow = Plant Capacity / 20 hrs

17.5 m3/hr

HRT = 2.5 Hours

Volume of Anoxic Tank = 43.75 m3

Hence provide an anoxic tank with a volume of ~ 50.00 m3


MBBR Tank:

Flow = 350 KLD.

MLSS = 5000 mg/L

Food to Mass ratio ( F/M) = 0.135

Total BOD in Kg/day = (BOD in mg/L x Plant Capacity) / 1000

Total BOD in Kg/day = 122.5 kg/day

user

Volume of Aeration Tank = Total BOD / ( MLSS x F/M Ratio)

= 181 m3

Hence provide an MBBR tank with a volume of ~ 180 m3


Calculation of Air Volume

"BOD5 after treatment <10 mg/lit

"BOD5 Loading = 350 mg/lit

"Total BOD5 load = 350 x 1000 x 350kg/day

1000000

"Total BOD5 load = 122.5 kg/day

BOD5 load in Kg/day in the aeration tank = 122.5 Kg

Oxygen required in Kg/day = 245 kg/day

(2 kgs of Oxygen is required for every Kg of BOD5 to be removed)

% of Oxygen in air = 0.21

Density of air = 1.2

Air Volume required per day = 972.2 m3 of 02 / day

No. of hours of oxygenation = 18

= 54.01 m3 / hr

Diffuser Transfer efficiency = 54.01 /0.18

(18 % for 4.5m submergence after providing for media loss)

= 300.06 m3 / hr

Hence, Air volume required in Aeration tank = 300 m3

/ hr

Consider 30% extra for equalization tank = 390 m3 / hr

Total Air Volume required = 390 m3 / hr

Therefore Total air requirement in Cum. / Day = 390 m3 / hr

Secondary Clarifier :


Loading Rate = 35.00 m3/sqm/day

Volume Considered in Design = 2 times plant capacity

Surface area of settling tank = Plant Capacity x 2 / Loading Rate

Surface area = 20 m2

6) CONCLUSIONS:

The STP would be able to treat the sewage to the standards prescribed by the TNPCB with

treated BOD levels less than 20 mg/lit. The treated water is safe to come in contact as the

chlorination is done to kill the bacteria disinfection. The treated water will be consumed in

irrigation, flushing toilets, HVAC purposes as well as washing pavements and driveways.
