A.Putrefaction – decomposition caused by anaerobic bacteria accompanied by bad odorsB.90cm x 150cm – minimum width and minimum length of a septic tankC.GradeD.Carbon Dioxide– is a combination of carbon and oxygen. It is the simplest oxide of carbon (CO2)E.Common Vent– is a drain from two or three fixtures connected to a single trap. Also called dual vent Branch– is any part of piping system other than the main riser or stackF.Secondary BranchG.Manhole – a device of the main and storm sewer. It serves as man’s access for inspection, cleaningand repair. (distance from each other 75- 150m) (diameter varies from 90-120cm)H.Standpipe - a vertical pipe extending from a water supply, especially one connecting a temporary tapto the mainI.Sanitary Sewer – a sewer intended to receive sanitary sewage with or without industrial wastes andwithout admixture of surface water, storm water or drainageJ.Stack – is the vertical main system of soil, waste or vent pipe.

It is subject to deposits of salt and lime thatgradually accumulate and finally choke the flow of water. It deteriorates faster when used as hot watersupply line.B.Aerobic Bacteria – survives only in the subsoil not more than 150cm below the surface, they cannotsurvive without oxygen C.Rigid Type – a type of copper pipe. Copper pipes can be rigid or flexible D.Reinforced Concrete - a vertical pipe extending from a water supply, especially one connecting atemporary tap to the mainE.Plastic Pipe – is a new concept in the field of plumbing. It was introduced in the Philippines at early70’s although it is developed in the midyear of 1935 in Germany. It is used in sewer and cold-water pipeline.
