Optimization of pumping operation system in massively developed industrial city of Cikande

Abstract

This paper presents the optimization of pumping operation system in one of massively developed industrial city in Cikande, Tangerang with total area around 2,400 ha. Flood control in Cikande area uses the detention pond at the end of system with the capacity 1,395,610 m3 and it is equipped with 5 pumps with the capacity 4.5 m3/s. There are two parameters are being considered as the important factors for optimizing the pumping operation, water elevation at reservoir and pumping operation pattern. The water elevation at reservoir is defined that shall not exceed +7 m. The results show, after implementing the clustering and long storage system, the capability of the existing operation system to handle the flood increased from 5 years to 10 years of return periods; however the operation is not effective because of the pumping operation patterns are impulsive which causes the pumps break easily. Hence, by using the new optimized pumping operation system, it is successfully and effectively controls various floods i.e. 2, 5, and 10 years of return periods.
