WATER QUALITY STATUS 2012‐2017COMPARED TO CLASS II
Result of monitoring of 600 sampling points in 90 riversUsing at least 21 water quality parameters (Physical, Chemical and Biological)
Parameters influence the water quality are E-coli,total coliform, BOD, COD , H2S
Pollutant sources : Domestic, livestock, Industry and Non‐point source
Heavily PollutedModerately PollutedSlightly PollutedGood

WATER POLLUTION CONTROL PROGRAMS AND ACTIVITIES BASED ON TMDL (DTBP AND ABP) DEVELOPMENT ‐‐‐‐>RESPONSE TOWARD DRIVER DAN PRESSURE
Permit system, supervision, inspection, law enforcement,Economic instrument and
technical assistance
Public services, supervision, community empowerment, Parthnership and technical
assistance
Concervation: Civil
Construction and Vegetation
Increasing of compliance for industries and other institutions
Increasing the number and operation of STP for domestic and small scale enterprises
Increasing the number and effectiveness of BMPs for non point sources (agriculture and urban runoff)
Improvement of Hydrology, morphology and water body ecology(River Restoraion)
Decreasing of Water Pollution Load
Decline of Max/min flow ratio
Decline of erosion and sedimentation
Decline Runoff Coefecient
Improvement of water quality

ISSUES OF TMDL IMPLEMENTATION IN INDONESIA
• The number of provinces and districts / cities that have performed TMDL/DTBP calculations is still small
• The most difficult challenge in applying TMDL is to determine the load or quality and quantity of wastewater required in the effluent discharge permit
• Provinces and districts / cities that have calculated TMDL / DTBP have not been able to apply the calculation results for the effluent discharge permits

APPLICATION OF TMDL IN EFFLUENT DISCHARGE PERMIT
• TMDL analysis is in accordance with the provisions of Article 23 of PP No. 82 of 2001: Determination of TMDL in water sources is used as a basis in effluent discharge permit
• The watersheds whose TMDLs have been established and applied, then: the load or quality and quantity of wastewater required in a effluent discharge permit is determined in advance together with all other pollution sources
• The watershed whose TMDLs have not been established and applied, then:a. the load or quality and quantity of wastewater required in a effluent
discharge permit is determined in case by case wise (using TMDL of a certain local/segment)
b. Use the national effluent discharge
