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. This research uses the Liu-Kang drainage system of the 1st drainage area of Taipei City in the case study 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 Liu-Kang system. The simulated results show that the overflow hydrograph with reductive tendency at manhole near the pumping station under RTC and the water depth is kept at nearly to maximum. |
