Abstract
Urban drainage systems are the most fundamental facilities in modern developed cities.
There are two types of sewer systems in urban drainage systems: combined and separated. The
waste water and the runoff caused by rain are drained in a single tunnel or pipe in the combined
sewer systems; while the separated sewer systems use two separate systems of tunnels or pipes to
drain waste water and runoff respectively. It has been indicated by many researchers that the
performance of the sewer systems often can not reach its designed capacity when rainfall with
larger return periods occurs. In the developed nations, real time control sewer systems are
therefore applied to make the sewer systems more efficient for inundation caused by heavy
rainfalls.
The main objective of the research is to simulate the performance (e.g. reduction of the total
overflow volume in the drainage system) of the current drainage systems under optimized gate
operations without extra capacity imposed to them. This research uses the Zhongang, Shijian, and
Baoyi drainage systems of the 4th drainage area of Taipei City to demonstrate the effectiveness of
applying real-time control (RTC) in Taiwan’s urban drainage systems. For the purpose of RTC
simulation, the multi-thread technology is employed to integrate the Storm Water Management
Model (SWMM), developed by US EPA, and a genetic algorithm library, called GAlib, to
simulate RTC in the case study areas. The simulated results show: (1) total overflow volume in
each pumping system which gates are installed in the manholes reduced under optimized gate
operations. (2) These pumping systems with gates installation connected by pumps reduced the
total overflow volume under optimized operations.
