All activities are arranged and in well-organized based on regular SOPs, there is continuous reporting on the observation and maintenance of spillway and outlets equipment. The purpose is to maintain the performance of the spillway and outlets equipment that will contribute to the safety of the dam and its reservoir. The works will include program implementation of the spillway and outlet equipment, examination and maintenance of spillway and outlet equipment to assess the condition and reliability also functional testing of spillway and outlet equipment. 6. Component 6, Reservoir Operation, with its activities of: Operation Protocols; Relationship with External Stakeholders; Debris Management The score is: at a very good practice (level 4). The DMU of Bengawan Solo RBO has prepared the rule curve for reservoir operation purpose as a protocol and continuously recorded with a structured process as required in the SOP of dam operation. The annual operation plan is prepared based on rule curve and recommendation Basin Coordinating Team for the proposed water requirement from the users. The Debris management is done as part of maintenance works in accordance with SOP which has been made in order to improve the performance of the dam and its reservoir that secure on all the operating conditions. 7. Component 7, Dam and Spillway maintenance, with its activities of: Dam, Reservoir and Access maintenance; Spillway and Outlet Structure maintenance. The score is: at a good practice (level 3). UPB BBWS Bengawan Solo has arranged the operation pattern of reservoir and has been carried out recording with a structured process because it already has SOP of dam operation. Waste management is done in accordance with SOP that has been made the goal is to increase the implementation of maintenance of the structure of the civil society and construction related to the dam and its reservoir. Including structural maintenance or repairs, erosion protection, control vegetation and drainage maintenance (drainage surface and drainage relief internal). Including spillway and electrical outlets that shows the function of the safety of the dam also electrical components and mechanical. 8. Component 8, Review and Audit, with its activities of: Dam Safety Program Audit; Dam Safety Program Reviews; Dam Safety Reviews; Flow Control Equipment Reviews. The score is: at a good practice (level 3). The dam safety program is prepared annually. As a part of the SOP, the implementation and the program are regularly audited and reviewed by DMU manager. While the dam safety review including the flow control equipment being done in semiannual basis by the ministry and 5 years basis for the major inspection by the Dam Safety Commission, not all inspections have been implemented but have been included in the strategic plan related to the implementation of the major dam inspection. 1159
