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.

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

Topics	Explanation
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.

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: Screening and primary filtration Primary sedimentation Advanced and secondary filtration Process of aeration Use of chlorine
