Pilot and Demonstration Activities
Development of a Water Quality Management System for the West Tarum Canal of the Citarum River Basin

The growing population in West Java's urban areas has brought pollution to the Citarum River Basin, leading to the dwindling of water quality. This PDA will pilot the establishment of a water quality monitoring and management system for the West Tarum Canal.

 
PDA SNAPSHOT
Project Site West Java, Indonesia
Cost Estimate $67,000
Status Completed
Approval Date 2006/10
Completion Date March 2008
Category Basin Management
Type Appropriate Technology
Proponent Chris Morris, Southeast Asia Department
Partner Korea Water Resources Corporation (K-Water)
BACKGROUND

Rapid urbanization and industrialization in the Indonesian capital of Jakarta has led to increasing pollution levels and deteriorating water quality in the Citarum River Basin (CRB). Pollution by urban effluents in the upper part of the catchment area, particularly in Bandung and Purwakarta, have resulted in water pollution in reservoirs, whose natural purification capacity have collapsed and now pose threats to the region's water supply. Low water quality in the CRB has also impacted on the operations of hydropower stations. Fishing and other recreational activities have become limited.

CRB — which is composed of 9 rivers, the West Tarum Canal (WTC) and East Tarum Canal, and the Saguling, Cirata and Ir. H. Djuanda (Jatiluhur) multi-purpose dams and reservoirs-is a major source of water supply to West Java's metropolitan areas. About 70% of Jakarta's drinking water supply comes from the Djuanda reservoir, transported through the WTC to water treatment plants in the city. Originally designed as an irrigation canal for rice production, the WTC currently serves different types of industrial and municipal users whose demands continue to increase and, in the process, generate pollution in the canal.

This PDA will pilot the establishment of a water quality monitoring and management system for the WTC as part of the Government of Indonesia's overall plan of addressing the sustainable water resources development and management of the CRB.

OBJECTIVES

The aim of this PDA is to pilot an approach that would address the issues of

  • Adequate database development through systematic monitoring of water quality
  • Development of a system to support better water quality management in the context of integrated water resources management (IWRM) of the CRB

Top

EXPECTED RESULTS
  Outputs     Outcomes     Impacts     Indicators  

  • A comprehensive water quality monitoring network appropriate for the WTC area in the CRB
  • Water quality database based on adequate monitoring activities, including identification of suspected sources of pollution
  • A sound water quality modeling system for WTC, highlighting the innovative aspects of the model structure
  • Increased capacity of Jasa Tirta II Public Corporation (PJT II) —the river basin organization in charge of managing CRB— in water quality monitoring and modeling, and increased awareness of other stakeholders

REPORT CARD

This PDA was completed in March 2008. Read the Final Report [PDF].

  Achievements     Recommendations  

This PDA

  • Developed a comprehensive water quality monitoring network for the West Tarum Canal (WTC) of the Citarum river basin. Fourteen existing monitoring locations adequately represented the general condition of water quality in the WTC. Additional monitoring points have been put in place
  • Provided various programs to enhance the capacity of PJT II, both for staff and management level. PJT II staff actively participated in project activities together with K-water, particularly in the design and development of the water quality monitoring network
  • Successfully conducted water quality monitoring and institutional capacity building and introduced better resources management practices to the top management groups of water
  • Held regular meetings with the main stakeholders to demonstrate the impact of knowledge and information
  • Promote public awareness on water quality management
  • Establish Best Management Practices (BMP) for the sustainable management of environmental and water resources in the CRB. A well-established BMP through the systematic water quality monitoring and modeling system can provide an appropriate strategy in establishing IWRM in the CRB as well as other river basins in Indonesia
