An experience in the 2006's Twinning Program


Reported by Aris Harnanto, Jasa Tirta I, Indonesia

As continuation of good cooperation between Indonesian NARBO and Japan Water Agency (JWA) under Network of River Basin Organizations (NARBO) umbrella, since the year of 2004, the Indonesian NARBO dispatched 4 personnel (Bekty, Irwan, Aris, and Herman) to JWA on June 12th – 25th 2006. The twinning program of this year is held as implementation of Agreement of Exchange Personnel on Twinning Program between JWA; Directorate of Water Resources Management, Directorate General of Water Resources, Ministry of Public Works ("PSDA"); Research Centre for Water Resources, Agency for Research and Development, Ministry of Public Works ("PUSAIR"); Jasa Tirta I Public Corporation ("PJT I"); and Jasa Tirta II Public Corporation ("PJT II") signed on 16 May 2006 in Jakarta.


During the twinning program to JWA, we held some discussion with JWA Staffs related to Integrated Water Resources Management (IWRM) implemented both in Japan and Indonesia. Beside that, we also had an opportunity to visit several locations in where JWA conducts its daily activities in managing the water resources. We visited Tone Canal Project, Urayama Dam, and Toyo Canal Project. In Tone Canal Project, we visited Tone Canal Control Center and Tone Diversion Weir, where we found a structure for fish way. Up to now, there are many fish ways have been constructed in Japan in order to prepare a way for migratory movements of fish. In the upper part of Urayama Dam we also visited a check control structure equipped with fish way and seem to be new structures that added to the existing structure. At present there is a project under construction called Urayama Dam Environment Project. This project consist of installation of 6.2 km length of pipeline for discharging 0.6 m3/sec water taken from the upper most of reservoir and convey to the downstream of the dam especially in case of flood and increased turbidity of water. During the construction, the construction site is so clean and we not found any garbage or unused material surrounding the site. When we visit a canal, we also found the specific structure to reduce noise from the water drop, so the public is not disturbed.

Last place to be visited was Banba Regulating Reservoir with surface area of 0.83 km2 and reservoir volume of 5 Mm3. The surrounding of Banba Regulating Reservoir is arranged such a way that looks beautiful and good environmentally sound. We also visited Water Exhibition Center; this place is good for recognition hygienic environment and to understand how to secure the water from upstream to downstream part. So, in the all activities, JWA has paid much attention to the environment, and that’s good to be learned and followed...
