drainage- he means of removing surplus water or liquid waste; a system of drains


shower- are fundamentally a very simple appliance designed to contain water and a person or two and to drain spent water into the sewer system.

urinals- is a container used to collect urine. It is shaped to fit either a man or a woman. But some women might find it easier to use a bedpan.

Drafting Notes

  Resource: PNU- TLE Drafting Concept of Drafting  In most cases before making the final plan it takes the form of sketches and drawing  Sketches usually precede the making of scale drawing of an object.  An attempt to make something without having a definite plan usually results in waste of materials and time as well as in a poorly constructed project. DRAFTING EQUIPMENT In order to do planning or drafting work it is first necessary to learn the names of the tools the draftsman uses and the way he uses them to produce a good drawing. In addition it is necessary to learn certain rules and regulations which are the principles of good drafting.  Drawing Pencils - Drawing pencils is made of a much better grade of graphite, commonly called lead, than the ordinary writing pencils so it is possible to draw lines which are of uniform blackness and to do better quality of line work. - The hardest of the drawing pencils is the 9H. The next hardest in order are the 8H, 7h, 6H, 5H, 4H, 3H, 2H
