4.2 Methodology

In order to ensure that all project activities are completed as per schedule and terms of reference, it is

necessary to follow a proper methodology. The methodology adopted by the Consultant for this project is

as follows:

Data Collection from Client

Engineering Designs for Sewer Distribution Network

Preparation of Detailed Cost Estimates

Preparation of Report




Chapter 5 Designs

5.1 General

The sewer network design usually involves using the survey data and design period factors, total

containment of sanitary wastes and maximum exclusion of infiltration and inflow to determine the size of

the pipe and location of the man holes. The pipe material selected for the pipeline is DI because it is

relatively cheap, easily available in most parts of the state and is very easy to repair. The following

sections will discuss the method adopted to design the Sewer Network.

5.2 Design Factors

The following factors are considered in the design of sanitary sewers distribution network.

Peak sewage flows from residential, commercial, institutional, and industrial sources;

Groundwater infiltration and exfiltration;

Topography and depth of excavation;

Treatment plant location;

Soils conditions;

Pumping requirements;

Maintenance, including manpower and budget;

Existing sewers;

Existing and future surface improvements;

Controlling service connection elevations

5.3 Minimum Size of Circular Sewers

The minimum diameter may be adopted as 200 mm for cities having present/ base year population of

over 1 lakh. However, depending on growth potential in certain areas even 150 mm diameter can also

be considered. However, in towns having present/ base year population of less than 1 lakh, the

minimum diameter of 150 mm shall be adopted.

In the case of hilly locations, the minimum diameter of 150 mm shall be adopted. The house sewer

connection pipe to public sewer shall be (a) minimum 100 mm or higher based on the number of

houses / flats connected and (b) subject to the receiving public sewer being of higher diameter.




5.4 Shape and Size of Sewers

In general, circular sewer sections are ideal from load bearing point of view in public roads and as the

hydraulic properties are better for varying flows.

In the current design 200 mm pipe diameter is considered.

5.5 Ductile Iron pipes

Ductile iron pipe is a pipe made of ductile iron commonly used for potable water transmission, and

wastewater sewer applications . it has become the most preferred pipe material for water supply and

pressure sewerage applications around the world. has a chemical composition which is very similar to

cast iron, it is considered superior due to its spheroidal micro-structure which has vast advantages such

as higher pressure bearing ability, impact resistance, corrosion resistance etc.

The standard diameters of pipes and flanges followed in this standard are as follows:

80, 100, 125, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 750, 800, 900, 1000, 1 100,1 200,

1 400, 1 600, 1 800 and 2 000 mm.

DI pipes rate are based on the pig Iron (Si. 2% - 2.5%) with WPI of 141. K 7 Class DI pipes conforming

to IS 8329:2000 with latest amendments and conveying to work site, rolling, lowering into trenches,

laying true to line, level and perfect linking at joints are used for Distribution network.

5.6 Flow in Circular Sewers

If the velocity and depth of flow is the same for the length of a conduit, it is termed steady flow and as

otherwise, it is non-steady flow. The hydraulic analysis of sewers is simplified by assuming steady flow

conditions though the actual flow conditions are different during morning peak flows and varying flows in

other parts of the 24 hours.

In the design of sanitary sewers, an attempt shall be made to obtain adequate scouring velocities at the

average or at least at the maximum flow at the beginning of the design period. The flow velocity in the

sewers shall be such that the suspended materials in sewage are not silted up; i.e., the velocity shall be

such as to cause automatic self-cleansing effect. The generation of such a minimum self-cleansing

velocity in the sewer, at least once a day is important, because if depositions are takes place and is not

removed, it will obstruct free flow, causing further deposition and finally leading to the complete blocking

of the sewer.




The smooth interior surface of a sewer pipe gets scoured due to continuous abrasion caused by the

suspended solids present in sewage. It is, therefore, necessary to limit the maximum velocity in the

sewer pipe. This limiting or non-scouring velocity will mainly depend upon the material of the sewer.

Thus the sewers are designed on the assumption that although silting might occur at minimum flow, it

would be flushed out during peak flows. Erosion of sewers is caused by sand and other gritty material in

the sewer and by excessive velocity.

5.7 Profile of Sewer System

The vertical profile is drawn from the survey notes for each sewer line. All longitudinal sections are

indicated with reference to the same datum line. The vertical scale of the longitudinal sections are

usually magnified ten times the horizontal scale. The profile shows ground surface, tentative manhole

chamber locations, size and material of pipe, ground and invert levels and extent of concrete protection,

etc. At each manhole chamber the surface elevation, the elevation of sewer invert entering and leaving

the manhole chamber are listed.

5.8 Manhole Chamber

A manhole chamber is an opening by which a man may enter a sewer for inspection, cleaning and other

maintenance and fitted with a removable cover to with stand traffic loads in sewers. Having designed the

sewer system, the manhole chambers are identified where ever required based on the ground profile to

accommodate the sub mersible pumps for pumping the sewage into the UGD system provided along the

walls of the storm water drains. The diameters of circular manholes for stated depths of sewers are in

Table 5.1 and List of Manhole chamber whever is required is listed in Table 5.2.

5.9 Sewer Distribution Network

5.9.1 Network Design

Considering the above design parameters Sewer network consisting of trunk line, mains, branches and

laterals has been designed. Manhole chambers are constructed wherever required to pump the sewage

into the UGD pipe line by providing 1 working and 1 standby submersible pumps in the manholes. The

sewer network is planned along the walls of the existing storm water drains 0.3 m below the top of storm

water drain.The detail of the Sewer network system is as follows.

Chapter 7 Recommendations

7.1 Introduction

Electronics City Industrial Township Authority (ELCITA) is the nodal agency responsible for looking after

the welfare of the companies who have put up their enterprises in the Electronic City. ELICTA would like

to ensure that the entire Electronics City comprising of various phases shall function as a smart city

providing world class facility in terms of communication, transportation network, pedestrian movement,

pollution free environment, state of the art drainage network, etc.

The purpose of the project assignment is to collect waste water from the septic tanks of the various

buildings through a network of pipe lines to the proposed 300 KLD STP in the Electronics City

Industrial Township Authority (ELCITA), Bangalore.

7.2 Pipe Material for Distribution System

It is proposed to use DI pipes for sewer distribution network system along the existing storm water

drains.

7.3 Method of Distribution system

It is proposed to adopt gravity and pumping based sewer distribution network system with brick masonry

manhole chambers for accommodating the submersible pumps wherever required.

7.4 Findings and Recommendations

Electronics City Industrial Township Authority (ELCITA) has established 300 KLD STP.

The STP will get the sewage from various industries through a network of Trunk lines/ Main

Lines/ Branches/ Laterals.

The entire network is designed to cater for 300 KLD capacity such that future demand can be

met without further augmentation.

The entire network of sewage network is planned along the existing storm water drains using

Ductile Iron pipes (DI) material and K7 class the flow will be by gravity and pumping.

Indivisual Units connections to the UGD network is not considere in the Design & Estimation.




Manhole chambers has been proposed wherever required of 1.75 m diameter and 2.0 m depth

for accommodating 1 working + 1 standby submersible pumps as per the design/ site

requirement.

Considering the project has to be developed in an urban area with restricted right of way a

provision for Restoration/ Relocation of Utilities/ Dismantling and Restoration of

Structures/ Disposal of excavated material etc. have been made in the cost estimate.

The total cost of the distribution network consisting of Trunk lines/ Main lines/ Branches

/ Laterals and Manhole chambers with submersible pumps is amounting to Rs. 247.00 Lakhs

as per the schedule of rates SOR of KUWS & DB for the year 2014 – 15.
