Academic Year: | 2026-27 | |---------------------------|-----------| | Semester: | 5 th | | Category of the Course: | PCC | | Prerequisite: | Students know Surveying, Building Materials & Construction, Fluid mechanics, design principles, Applied & Structural Mechanics at a basic level, Soil Mechanics. | |-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Rationale: | Water is very important element in civilization. Social life developed on the bank of Water-source. The mental as well as social health plays vital role for remarkable growth of society. For that purpose, Pure, potable and palatable water to be supplied to the society and to maintain the hygiene of it, the waste water must be collected and treated properly before disposed of in nature, so the natural flora and fauna will not get affected by sewage disposal. In present time, solid waste also wants more attention. The technician must know about the quality as well as quantity of domestic water to be supplied to the society. Similarly, technician should be conversant with the collection, conveyance, treatment and disposal of waste water. | ## Course Outcome: After Completion of the Course, Student will able to: | No | Course Outcomes | RBT Level | |------|-------------------------------------------------------------------------------------------------------------------------|-------------| | 01 | Understand the importance of Water Supply and Sanitary Engineering. | R, U | | 02 | Calculate and Estimate the impurities present in water used for Domestic as well as Civil Engineering project works. | R, U & A | | 03 | Lay and perform maintenance of water distribution system and sewer-networks. | A | | 04 | Decide the requirement of treatment to make water potable and the treatment require for sewage to safely disposed off. | R, U & A | | 05 | implement house plumbing work effectively. | R, U & A | *Revised Bloom's Taxonomy (RBT) ##
