Abstract
This study aimed at modelling the wastewater
collection system in Cha-Am Municipality using PCSWMM to
investigate the quantity of combined sewage delivered to the aeration
lagoon treatment system (ALTS). Cha-Am is a small sea resort town
in Petchaburi Province located about 175 km southwest of Bangkok
and is facing increasing development so it is important to understand
current system performance and plan for future build out. PCSWMM
was calibrated using observed ALTS inflow data for the period 15
June to 20 July 2015. The model was validated using observed ALTS
inflow data for the periods 19 July to 20 October 2015 and 1 October
to 31 December 2015, respectively. The 1:1 lines between modeled
and observed peak flow and event volume for the calibration events
qualitatively showed good correspondence. The r2
values between
modeled and observed peak flow (99%) and event volume (89%) also
were strong.
