Abstract

Madiun River catchment area is widely known for flooding in the rainy season. There is an embankment built to prevent the flood from entering the city. With the existence of the embankment, pumps are required to discharge the rainwater from the urban drainage channel into the river. The pumps located in the pumping stations are spread across the Madiun City. Each pumping station has a different capacity and different catchment areas. Nevertheless, its capacity is not sufficient to discharge the water flowing from the drainage channel into the river without causing flood in the city. Hence, the evaluation of pump capacity is necessary. In this study, a case study of Pancasila Pumping Station as a pumping station with the biggest catchment area is taken. From the rainfall data, flood discharge in the inlet of the pumping station is calculated using a synthetic unit hydrograph of the Nakayasu method. The capacity of the pump will be evaluated using the resulted flood discharge, whether the capacity is sufficient or not. Furthermore, the necessary pump quantity, the pump capacity, the operational hours, and the volume storage needed will be calculated. The results are: maximum flood discharge with a return period of 10 years is 20.206 m³/s, the existing pump capacity is only 1,000 litre per second while the required pump capacity is 5 m³/s with the quantity of two units, both operated in the same time for 8 hours and one unit is operated for the ninth hour, equipped with a storage volume of 102,017 m³. Thus, the addition of pump capacity is necessary.

Abstract

Sustainability is one of the principles in infrastructure asset management. In a hydropower project, Hydropower Sustainability Tools (HST) are needed in assessing sustainability principles into practice when developing new hydropower projects. International Hydropower Association (IHA) published guidelines consist of three documents; one of them is Hydropower Sustainability Assessment Protocol (HSAP). This study is a mini-review focusing on the implementation of HSAP in hydropower projects in Indonesia, including the Pelosika project in Southeast Sulawesi, the Ir. H. Juanda project, and the Bendung Perjaya project in South Sumatra. HSAP has its advantages and disadvantages, it covers a variation of topics widely, but the assessment is somewhat subjective, time-consuming, and cost-intensive. HSAP is relatively new in Indonesia; there are not many publications regarding this topic. Future studies are recommended to know more about its potential in increasing the sustainability of hydropower projects.
