Abstract
This research has two main objectives which are to monitor the water quality of
selected high-rise residential building in Seberang Perai, Penang and compare the result
with Malaysian drinking water quality standard and to estimate chlorine availability and
its water ages at the user’s end using EPANET 2.0 modelling software. This study was
carried out to examine the drinking water quality of high-rise residential buildings
distribution network in Universiti Sains Malaysia by collecting samples from 2 different
locations (Desasiswa Tekun and Utama). The aim is to determine the potential
relationship between the water age stored in the tanks with the chlorine in the distribution
network and test weather can the EPANET 2.0 be use to estimate or predict water quality
in small building. The residual chlorine is tested in situ immediately while pH, turbidity
and colour are brought back to school of Civil Engineering’s laboratory for the test. The
water age and chlorine availability were estimated by using water distribution network
software modelling EPANET 2.0. The result of this study have shown that assessment
of drinking water quality at both USM high-rise residential building and estimation by
using EPANET 2.0 water distribution simulation modelling software, this study
elucidated that the quality of water supplied are fulfilled the Malaysia drinking water
quality standard which is pH of water is within 6.5-9.0, turbidity contain are less than 5
NTU, colour of water is less than 15 TCU and free residual chlorine contain are within
0.2-0.5 mg/l. The value of chlorine contains predicted by the EPANET 2.0 was lies
within the range of result in-situ tested .
