Public Health Engineering — यह विषय किस बारे में है
हर शहर को दो अदृश्य systems चाहिए: साफ़ पानी अंदर आना, और sewage सुरक्षित रूप से बाहर जाना। Public Health Engineering वह विषय है जो आपको दोनों सिखाता है। यह एक practicum विषय (4.9) है, 100 अंकों और 2 क्रेडिट का, जिसमें 1 lecture और 2 practical hours प्रति हफ़्ता हैं, और उसकी lab एक water-testing lab है — pH, turbidity, chlorine, dissolved oxygen, BOD और COD।
आप किसी शहर की population और उसकी पानी की demand का पूर्वानुमान लगाएँगे, water treatment plant design करेंगे (sedimentation, filtration, chlorination), distribution system का layout बनाएँगे, sewers और उनके appurtenances design करेंगे, और sewage की primary व secondary treatment सीखेंगे — जिसमें sewage या water treatment plant की field visit भी शामिल है।
विषय 4.9 (Practicum/Theory) • कुल 100 अंक • 2 क्रेडिटs • L 1 – P 2 • चौथा सेमेस्टर — Civil Engineering • सत्र 2026–27
नोट: 4th-semester scheme के totals से पता चलता है कि इस विषय के 40 internal अंक Practical assessment के तहत आते हैं, जबकि उसके 60 external अंक Theory के तहत आते हैं (extract की गई table के columns की alignment गड़बड़ है — NOTES देखें)। यहाँ दी गई lab work subject 4.9 का ही हिस्सा है।

Sewage और sewers — conservancy और water carriage systems, sewer appurtenances, और sewers को lay करना व test करना।
Unit 5 — Characteristics and Treatment of Sewage (3 Periods, 20%)
Sewage characteristics: properties of sewage and IS standards for analysis of sewage, physical, chemical and bacteriological parameters; natural methods of sewerage disposal: general composition of sewage and disposal methods, disposal by dilution, self purification of stream, disposal by land treatment, nuisance due to disposal; sewage treatment: meaning and principle of primary and secondary treatment and activated sludge process, their flow diagrams, introduction and uses of screens, grit chambers, detritus tanks, skimming tanks, plain sedimentation tanks, primary clarifiers, secondary clarifiers, filters, control beds, intermittent sand filters, trickling filters, sludge treatment and disposal, oxidation ponds (visit to a sewage treatment plant), oxidation ditch, duckweed pond, vermiculture; building drainage: aims of building drainage and its requirements, different sanitary fittings and installations, traps; introduction to smart water supply and waste water management: a field visit may be planned to explain and show the relevant things.
Sewage treatment — primary और secondary treatment, activated sludge process, oxidation ponds, और building drainage।
