DETAIL DRAWINGS FOR SANITARY INSTALLATION3-dimensional visualization of thetoilets’ and hand basins’ connectionsin ground floor and first floorPlanning the sanitaryinstallationMaking a freehand sketch of thelavatory and it’s sanitary furnituregives a basic idea of the futurelocations of the furniture. Partitionwalls as well as the height of tilingand it’s layout are considered.Proper sloping of the wastewaterpipes in mind, the locations andthe dimensions of pipes are specified.For installations that passno solid wastes into the systema diameter of 55 mm is normallysufficient. For others, like toilets,a diameter of 110 mm is needed.Connectors and reducers have tobe chosen and properly specified.Fall pipes have to be plannedstraight and unbroken through allstoreys. They should have a ventilationopening at the upper endand have to extend up to the roof.Proper ventilation of the fall pipesand the house drain is importantto prevent the siphon traps formemptying when flushing toilets.The first sketch of the sanitary installation in the ground floor toiletThe connection of the pipes to thehouse drain should be rounded toprevent clogging.Sanitary designs have to be doneor approved by an engineer.The final detail drawing with all necessary measurements and technical descriptionsTHE KASANCHIS RENOVATION PROJECT HINTS ON THE PLANNING PHASE39Addis AbabaCity Government
