HEALTH PROJECTS
Learning objectives
- Discuss conventional symbols used in environmental
health projects - Explain how to design and draw water and sanitarian
projects - Draw some of water and sanitary facilities that are to
be built at the community level
Introduction
Modern planning and designing demands a very precise
system of environmental projects (water supply and disposal
of sewage) in a building. If properly laid this system leads to a
healthy and hygienic living. It deals with water supply in a
building and then its proper disposal in the form of sewerage
from the same building. Graphical symbols and depiction of
sanitary fittings be thoroughly understood before making such
drawings.
