Abstract

The purpose of the study was to compare high density polyethylene (HDPE) and polyvinyl chloride (PVC) pipes used in the sanitary drainage system or the Hotel Parcvue project in Alabang. The physical and chemical properties of HDPE and PVC were identified and compared. The differences in installation methods for both pipe materialswere also analyzed. Furthermore, the costs of using PVC and HDPE pipes were compared. Research from he internet and books were done to identify the properties of the pipe materials. Observations at the project site also done to be familiar with the processes and methods of installation of the pipes. It was found that the advantage of using PVC is that it can withstand higher pressure than HDPE. This makes it more suitable for pressurized systems. On the other hand, HDPE pipes are more elastic and lighter; which make HDPE pipes easier to handle and transport. HDPE pipes take longer to install because it uses butt fusion technique while in PVC pipe installation, cement adhesives are used. The use of HDPE pipes also led to the use of air admittance valves (AAVs) as replacement for vent pipes. It was found that the installation of AAVs was cheaper than using PVC vent pipes by Php 174.33 per toilet and bath. The use of AAVs also led to save some space for other costruction processes required.
