Water and Wastewater is an essential part of the syllabus for all engineering examinations like GATE CE, computer science, ESS, and JEE. 71% of the earth is covered with water, but only 0.3% of the water is found to be usable for humans. Keeping in mind that this important natural resource is really limited in nature, we need to implement proper water management and treatment systems to preserve this natural resource for future generations. Wastewater is the liquid waste released by households, factories, and businesses, containing vegetable waste, chemicals, and other harmful substances. This article will tell you where to go for water and wastewater study material for GATE CE, water and wastewater GATE questions and answers, water and wastewater quiz, water and wastewater books to study, water and wastewater notes for GATE pdf, water and wastewater for computer science, and water and wastewater syllabus for GATE.

Important Water and Wastewater Terminology for GATE CE

Water and Wastewater syllabus for GATE CEoften includes questions from these definitions and terminologies.



Surface sources of water

These are the sources of water that are a result of rain, water from melted snow, and other natural phenomena. These are the sources of water that are found on the surface of the earth like ponds, lakes, oceans, and rivers, etc.

Underground sources of water

These are the sources of water that are found underground or beneath the surface of the earth, like wells, springs, and underground water, etc. These are usually referred to as sub-surface sources of water.

Water quality

Water quality is the testing of the quality of the water on the basis of the physical, chemical, and biological characteristics. These tests are done to see if water fits the expected requirements.

Wastewater treatment plants

Wastewater treatment plant is a treatment plant where contaminated wastewater is treated to make it fit for use. It purifies wastewater from biological, chemical, and physical contaminants.

Steps for water treatment

Water treatment follows a specific order of steps to reach households:

  1. Screening and primary filtration
  2. Primary sedimentation
  3. Advanced and secondary filtration
  4. Process of aeration
  5. Use of chlorine

Steps for wastewater treatment

Wastewater treatment follows 3 steps for treatment of wastewater:

  1. Primary treatment of wastewater
  2. secondary treatment of wastewater
  3. Tertiary treatment of wastewater
