Category of the Course:

PCC

Prerequisite:

Rationale:

Students know Surveying, Building Materials & Construction, Fluid
mechanics, design principles, Applied & Structural Mechanics at a basic level,
Soil Mechanics.
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:
