I am OK You are OK

Dear Reader ,

This post is being specially written for one of my students.

He had just called me to know what are the things asked in a interview.

I am sharing some thoughts for all job aspirants :

[ Already we have two posts with title :

Welcome …please be seated &

Interview questions which offer some important tips for the successful interview.]

1. Be on a transaction level of ” I am OK you are OK “

Before I expand on this philosophy , let me tell you .There are four basic types of transactions possible :

1. I am OK but  you are not OK :  

Not the right attitude specially during interview.

2. I am not OK but you are OK :

Why to feel inferior ? We are there to seek a job .After all we are exchanging our quality time with salary. We are going to deploy our expertise and experience for that organisation. 

3. I am not OK and you are also not OK :

If you go with this attitude then you would not be optimistic and positive. A gloom shall be on your face.

4. I am OK and you are also OK :

This is the most advisable attitude.

This means we are there because of mutual needs.

No one is obliging any one.

No one is inferior no one is superior.

its equal equal.

We need to possess an attitude of gratitude during the interview.

Regardless of whether we are getting selected or not.

If we are selected, we are getting a job but even if we are not appointed there , at least we have been blessed with an opportunity to express ourselves and to learn how the interaction takes place during the interview.

Go with confidence and be a winner 

All the best 

PS : Before you go for interview , ensure that you have perused all the posts of this blog. that shall refresh the basic issues  in your mind.

Not really a dirty topic !

Overview:

Although the actual execution of plumbing and sanitary works is done after completion of the RCC work and masonry work , it is necessary to include this in the master planning in the beginning of any project.
This article gives inputs on the overall scope of plumbing and sanitary works and gives insights as to how to execute this in a way that maintenance does not become a       nightmare.

PLUMBING IS UP TO THE TAP. ONCE WATER IS USED, IT COMES UNDER THE PURVIEW OF SANITARY.
PLUMBING IS UP TO THE TAP.
ONCE WATER IS USED, IT COMES UNDER THE PURVIEW OF SANITARY.

What’s the basic difference ?
Plumbing talks about all pipelines, valves storage & distribution system related to fresh , usable water whereas sanitary refers to everything related to waste water.

Scopes defined:

The scope of plumbing starts from source of water, storage , distribution up to the tap at your home.
The moment this water comes out from the tap and is used or ( abused ),it comes under the scope of sanitary.

PLUMBING STARTS  FROM NATURAL SOURCE OF WATER AND COMPLETES AT THE BIB COCK

Plumbing Scope detailed out

Plumbing would start from the river or lake or open well or bored well to Jack well to pipe line to storage to filtration plant to water distribution system to underground storage tank to pumps to overhead storage tank to loft tanks to individual taps or cocks in the apartments.

Sanitary Scope detailed out: 
Sanitary would start from wash basin to waste coupling to drain pipe to gully trap to chamber to septic tank to soak pit or municipal drainage system.

SANITARY STARTS FROM A COMMODE AND COMPLETES AT SEPTIC TANK OR SEWAGE TREATMENT PLANT
SANITARY STARTS FROM A COMMODE AND COMPLETES AT SEPTIC TANK OR SEWAGE TREATMENT PLANT

Black water & grey water:
All waste coming out from the latrines which is also known as human excreta or night soil is called as black water.

ALL MATTER COMING FROM THIS ORISSA PAN TO THE DRAINAGE IS TERMED AS BLACK WATER
ALL MATTER COMING FROM THIS ORISSA PAN TO THE DRAINAGE IS TERMED AS BLACK WATER

Every other waste from the house is termed as grey water or also known as ablution water.

ANY WASTE WATER COLLECTED THROUGH ANY FLOOR TRAP IS TERMED AS GREY WATER
ANY WASTE WATER COLLECTED THROUGH ANY FLOOR TRAP IS TERMED AS GREY WATER

Nature of Black water:
This is organic matter containing biological waste from the body and is therefore has high BOD content.
BODBiological oxygen demand.
Higher is the organic or putrefying matter higher shall be the BOD value)

Nature of Grey water:
All effluent from wash basin , bath rooms , kitchen sinks , utensils wash ,washing machine is termed as grey water and it is basically inorganic in nature with lot of chemicals from various soaps , detergents, shampoos , body wash etc.

Single line  collection system :
Black water and grey water are collected in a single pipe line and is taken directly to the septic tank.

Advantages:
There is only one line to be provided and hence economical  as compared to double lines.

Disadvantages:

Septic tank has to be adequately designed to cater the combined load of black & grey water and hence it has to be much bigger in size .

In case of any blockage in the single pipe line , the entire sewage system shall render useless and shall call for emergency maintenance.

DOUBLE LINE SYSTEM . [ OBSERVE A SEPARATE DRAIN PIPE CONNECTING TO LATRINES AND ANOTHER TO ALL FLOOR TRAPS.
DOUBLE LINE SYSTEM .
[ OBSERVE A SEPARATE DRAIN PIPE CONNECTING TO LATRINES AND ANOTHER TO ALL FLOOR TRAPS.

Double line  collection system :

Black water and grey water  are collected in different pipe lines. Black water  is taken directly to the septic tank whereas grey water is discharged into the municipality drainage.

Advantages:
Septic tank has to be adequately designed to cater the combined load of black & grey water and hence it has to be much bigger in size .

Disadvantages:
Only disadvantage is that since one line is only catering to black water , there shall be lesser flow and hence probability of chock in the pipe shall be higher.

What is a septic tank ?
It is a method by which the unstable black water which is highly putrefying is converted into inorganic and stable output through a process of decomposition.

Structure of septic tank :
Visualize a long box with 2 partitions creating 3 equal compartments .First partition has opening at the bottom while the second partition is open at the top.

SEPTIC TANK IS BEING CONSTRUCTED IN BRICK MASONRY

Process in a septic tank :
The black water enters in the first compartment while the treated water leaves the last compartment.
The central chamber is where the anaerobic bacteria decompose the organic matter into a stable mass.
The output of septic tank are : sludge , liquid and foul gases.

ENTRY CHAMBER OF A SEPTIC TANK
ENTRY CHAMBER OF A SEPTIC TANK

Short circuit of septic tank :
If the untreated waste gets discharged through outlet.
This can happen if the opening in the first partition is kept at the top ( instead of at the base ).

Choke in the septic tank :

The sludge deposits at the base of the septic tank. If it is not cleaned at a specific interval , this prevents the passage of waste water from first to second compartment. The  entry chamber is thus flooded and does not allow entry of additional waste water.This is a very troublesome situation since the toilets on the ground floor gets flooded with back water .
Only solution is to immediately clean the sludge .This is done with a sludge pump which is mounted on a tanker.The sludge is sucked by the pump and gets filled up in the tanker.

SOAK PIT UNDER CONSTRUCTION AT A SITE
SOAK PIT UNDER CONSTRUCTION AT A SITE

Soak pit:

The effluent from the septic tank is discharged into the soak pit from where it gets slowly absorbed into the soil beneath through percolation.
Soak pit needs to be provided only when there is no municipality drainage in that locality .

Construction of a soak pit:

Brick bats are filled up in a deep circular pit and the septic tank effluent is discharged at the centre through a percolated pipe. Top of the soak pit is usually covered with coarse sand only.

Manhole or chamber:

A chamber is smaller in size . If it is large enough that a  person can down inside for
maintenance , it is known as the manhole.
A chamber is normally cubical in shape whereas a manhole is cylindrical or conical in geometry.
