Plumbing and Pipeling (Theory & Practical)

Plumbing system design remains an integral part of every Building. This means that the Plumbing design engineer must provide a system with great efficiency for waste and pollution removal, efficient water distribution and usage and efficient energy retention.

This is a field where vast experience is required. Plumbing design systems will tap knowledge from numerous fields such as Process engineering, Civil engineering, Mechanical engineering and Materials engineering. A great Plumbing system is one with a good fit in the ecological eco-system in reducing harmful and deleterious wastes.
