PRESIDENT DIRECTIVE

1. Reduction of Pollutant Load to the environment  through compliance  

for water pollution and air pollution from 680 industries in 2010 and 

continue ( planning for 2014 : 2000 industries) 

2.   Reduction of hot spot from forest fire for 20% per year

3.   Reduction of pollutant load entirely until 50% in 2014 (Baseline    

calculation for domestic waste water based on population in    

2010, potential BOD load = 2,584,825.70 ton BOD)

4.   Improving  environmental degradation on the 11 watersheds start

CHALLENGE AND OPPORTUNITY IN WASTE WATER MANAGEMENT IN INDONESIA

A. Technical Aspect

• Improper on‐site treatment plant to treat both black and grey water• Need an advanced technology to install the pipe in the main road• In some cities many high rise building already have treatment plant• Need pumping system on flat land condition

B. Financial Aspect• Need an enormous amount of financing Investment to construct 

sewerage system.• Local and Central government have limited financial source• Wastewater business characteristic doesn't meet investors need, 

because of long term Return On Investment

CHALLENGE ------- (CONTINUE)

C. LEGAL ASPECT

• Dispute/unclear of job description among local institutions whoresponsible to handle wastewater management

• No local regulation to manage community right and obligation inwastewater system

• No Public Private Partnership guideline/standard related towastewater management system

D. CULTURE AND SOCIAL ASPECT

• Lack of Community awareness in term of good quality sanitation.• Lack of community understanding in term of wastewater treatmentplant both “ black and Grey Water” should be treated
