How to prepare for Environmental Engineering for GATE
How to Prepare GATE Civil Engineering
Environmental is one of the biggest boulders coming in your way to good scores in the GATE examination. You would have gone through analysis of previous year papers, but in case if you haven’t let me get it clear. Environmental Engineering (also known as water supply engineering) comprises an average of 10.2% of GATE’s overall marking scheme. This subject overlaps a subsequent part from Geotechnical Engineering and Engineering Hydrology which increases the importance of this subject in various Examinations.
In GATE Civil Engineering Syllabus, the below is part of GATE Environmental Engineering-
Water and Waste Water: Quality standards, basic unit processes and operations for water treatment. Drinking water standards, water requirements, basic unit operations and unit processes for surface water treatment, distribution of water. Sewage and sewerage treatment, quantity and characteristics of wastewater. Primary, secondary and tertiary treatment of wastewater, effluent discharge standards. Domestic wastewater treatment, quantity of characteristics of domestic wastewater, primary and secondary treatment. Unit operations and unit processes of domestic wastewater, sludge disposal.
Air Pollution: Types of pollutants, their sources and impacts, air pollution meteorology, air pollution control, air quality standards and limits.
Municipal Solid Wastes: Characteristics, generation, collection and transportation of solid wastes, engineered systems for solid waste management (reuse/ recycle, energy recovery, treatment and disposal).
Noise Pollution:Impacts of noise, permissible limits of noise pollution, measurement of noise and control of noise pollution.
Coming on to the point that how to prepare for it. Environmental Engineering is all related to water, its quality and treatment of water, so we will discuss it in three parts:
- Raw water Engineering –
This portion of Environmental Engineering is very useful in practical life, on how to supply water to households, industries, etc. Students who like studying by relating things to real-life might get a good interest in this portion. Here, only sub-surface sources of water will be discussed. For Surface sources, we have a different subject with the name ‘Engineering Hydrology’.
- The topics comprise in raw water engineering include:
Forecasting of population, Sources of water, Physical, Chemical, and biological characteristics of water, Distribution, and conveyance system.
- Sewage Engineering –
This portion of Environmental Engineering deals with the wastewater and also termed as wastewater engineering. Many of the colleges provide field visits to a sewage plant in that area for a proper demonstration of their students. But if you haven’t visited, no problem at all, it won’t matter much to visit it to understand. Just stick to the treatment processes and work of various processes in treatment plants.
The topics comprise in Sewage Engineering include:
Systems of Sewage, Characteristics of sewage, Treatment of Sewage, and Disposal of Sewage.
- Air and Noise pollution –
Well, I don’t need to explain much about this portion of Environmental Engineering, you would have already studied it in catholic schools as E.V.S. subject. But considering it easy enough might cost you about 2 to 4 questions in the GATE exam.
Since we have let you know about its parts and how to study them. Let us talk about reference books that might be helpful on such occasions.
The reference books are –
- “Water Supply Engineering” by B.C. Punmia Vol 1 & 2
- “Water Supply Engineering” by Dr. P.N. Modi Vol 1 & 2
DISCLAIMER FOR STUDENTS:-
There are many other books out there in the market you may refer them also but remember stick to only one. Referring to too many books will do you no good, instead, you will end up exhausted and confused.
For study materials, if you are unable to pay for study materials, YouTube is filled with many video lectures of good faculties. You can refer to those for good understanding along with reference books.
Another very important thing is that Air and Noise pollution may cover 2 to 4 questions in GATE examinations, and taking it lightly might affect your GATE score subsequently.
