Ready to practice? Launch the mock test below.
These topic-wise mock tests cover the complete Environmental Engineering syllabus for GATE Civil, ESE, and SSC JE — including water supply, treatment processes, sewage systems, and waste water management. Each free test has 10 MCQs with detailed explanations.
Environmental Engineering for GATE Civil and ESE covers: water quality parameters (BOD, COD, DO, turbidity), water supply system design (population forecasting, demand estimation), water treatment processes (sedimentation, coagulation, filtration, disinfection/chlorination), sewage characteristics, sewage treatment (primary, secondary — trickling filter and activated sludge process), waste water disposal, and basics of air pollution and solid waste management.
These tests are ideal for undergraduate civil engineering students and candidates preparing for GATE Civil Engineering, ESE Prelims, SSC JE Civil, state PSC/PWD exams, and any other civil engineering competitive examination. All tests are completely free — no account needed.
Environmental Engineering carries approximately 5–9% weightage in GATE Civil Engineering, typically 5–9 marks out of 100. Water treatment processes, BOD/COD relationships, population forecasting methods, and sewage treatment are the most frequently tested topics. It is a moderately weighted but highly scoring subject with many formula-based numerical questions.
In ESE Prelims Paper II (Civil Engineering), Environmental Engineering typically accounts for 12–18 questions, carrying 24–36 marks out of 300. ESE covers both water supply engineering and waste water treatment comprehensively, including design calculations for treatment units, population forecasting methods, and quality standards.
For SSC JE Civil Engineering, important topics include: sources and types of water, water quality standards (BIS and WHO limits), water treatment methods (coagulation, sedimentation, filtration, chlorination), types of sewers and sewer systems, sewage treatment plants (septic tank, Imhoff tank, trickling filter, activated sludge process), and basic air pollution concepts. Numerical questions on BOD, population forecasting, and per capita demand are commonly asked.
