Water Treatment-
When the quality of water is not satisfactory, then the water is made suitable for the intended use.
It includes removal of,
1.Pathogens.
2.Suspended matters.
3.Color and odour producing substances.
4.Chemicals not suitable for drinking or other use of water.
5.Turbidity.
The above mentioned materials are removed in a water treatment plant.
This process is completed by the series of units which are suitable to the raw-water, characteristics of raw-water source and the desired quality of finished water.
Raw water is entered in the coagulation & flocculation tank. By passing through theunits, treated water is collected from the disinfection tank.
A water treatment plant is designed on the basis of maximum daily flow.
Type and degree of water treatment
The type and degree of water treatment will depend upon the
1.Source of raw-water.
2.Intended use of water after treatment.
If clear water is obtained from the lakes or reservoirs, only filtration and disinfection units may be required.
Generally ground water requires no treatment, if there are no chemical precipitates present in the water.
However, filtration is necessary for lime softening, removal of iron and manganese etc.

Important tips for
#BMC
@MACEDHULE
1.As fast as possible cover entire technical syllabus(the one recommended)!!
2. Do not solve numericals
3. Ssc JE level technical MCQS are expected
4.Read as much matter as u can!!
5.Solve Gate previous 1 mks question, ESE theoretical questions, ssc previous years & MPSC previous years questions. Cover all these mcqs first.
When u are done with these questions(these are almost 12000+ questions) then only go for objective books like, PN khanna & VS murthy
6.There are around 8 most important reasoning topics as far as IBPS is concerned.
Solve 5 questions of Evry topic on daily basis, this will help u become fluent in reasoning thereby increasing your speed and accuracy!!
7.focus on
#Solid Mechanics
#Soil Mechanics
#Concrete technology
#Highway
#Survey
#Environment
#QSV
After covering these topics then only move to others.
❤SOM❤Soil❤Environment❤ Will make the difference!!!
8.Remember a proper balance between technical and nontechnical is keyword of getting through #BMC!!!!
9.Those already done with technical Study everything, don't leave anything from civil engineering.
Good luck All!!!

1)Surface Sources
(River has Suspended Solids so need primary secondary treatment)
2)Sub-Surface Sources:-
Infiltration Galleries are porous pipes Galleries,
Infiltartion Well or Jack well are No.of RCC Ring wells constructed at bottom of river
Spring and it's 3 types:-
Artesian,Gravity and Surface Spring
Wells,
Tube Wells:-Strainer tubeWells (mostly used in India),
Gravel Pack Type tube well,Cavity tubeWells..
Ground water Requires Disinfection only
Intakes:- Structure for Conveyance of Water
Types of Intake:- Submerged & Tower Intake
Types of Metallic Pipes
& Non metallic Pipes**(Uses)**
Types of Joints(Recommended For which Pipes vichartat)
Types of Valves(Location & Function)
Population Forecast Methods:-
GOI manual Suggested Geometric Increase Method giving population of Young and Rapidly developing Cities..
Arithmatical Increase Method(Old Towns)
Incremental Increase
Logistic Curve
Comparative Graphical
Master Plan
Apportionment Method..
Simple Graphical,etc.
Water Demand:-
Domestic Water Demand
Full flush (200lpcd)metro area
Non flush (135 lpcd)for LIG(Low income groups)
Industrial,Commercial,Public,
Thefts losses and Fire demand
Fire Demand:-
If water in Kilo litres then use GOI Formula=100√P
Where p is Population in Thousands always note it
Or
else use (suitable formula)
Kuicking formula=3182√P
Co-incident Draft=
Max Daily Demand + Fire Demand
OR
Co-incident Draft=
1.8 Avg Daily Demand + Fire Demand
Per Capita Demand:-Annual avg.of daily water reqd by one person & includes all types of Water demands.
335 lpcd (Full flush)
270 lpcd (Non Flush)
Variations in Water demand**(Very imp.)**
Max daily water demand =1.8q
Max Hourly=1.5q
Max weekly=1.48q
Max monthly=1.28q
Max hrly of Max Day(Peak Demand)=2.7q
Goodrich Formula
Pumps,Pipe Mains,Source of Supply designed for Max.Daily Consumption
🌟Filter units designed for Twice Avg.daily demand or Max daily consumption
Distribution system designed for Max hrly demand on Max Day or for Co-incident draft
