Explanation of Water Quality Standard A ( Incompliance with Standard) B ( Slight Polluted) C ( Medium Polluted) D ( Heavy Polluted)
Regulation – Goverment Regulation No. 82 Year 2001 about Water Quality Monitoring and Water Pollution Control – Goverment Regulation No. 42 Year 2008 about Water Resources Management
Efforts for Water Pollution Control in Ciliwung River Basin • Transboundary Synchronization and Coordination in Pollution and Degradation Control Programs in Ciliwung River Basin: - Sampling Points Agreement - Institutional Capacity Building - Coordination between Institutions - Data and Information Management
AGREEMENT ON WATER POLLUTION CONTROL AND MONITORING 1. Determining targets for water quality standard of achivement along 20 year are : • Upsteam area in Bogor Regency before entering Bogor City: Class I • Bogor City : Class II • River segment in Bogor Regency after Bogor City before Depok city: Class II • Depok City : Class II • South Jakarta before Manggarai: Class II • Urban area in downstream (Jakarta) start in Manggarai : Class III
AGREEMENT ON WATER POLLUTION CONTROL AND MONITORING 2.Ecosystem and Sector- Authority based river basin management (MoE, MoA, MoF, MoHA, Local Government, etc) 3.Coordination River Monitoring Activity 4.Prioritazing Management Actions based on problem typology in field
WATER QUALITY MANAGEMENT • Integrated water quality management based on Government Regulation No. 82/2001 on Water Quality Management and Water Pollution Control (Article 9 Section 1) states that water classification of river located in two or more provinces is determined by the President. • Integrated management is based on Master Plan as a guidelines for National Board of Planning, Provincial and Local Board of Planning in arranging action plan.
